Decrements the memory data specified by the operand by 1.
On every execution of the instruction the device specified as the (D), has its current value decremented (decreased) by a value of 1. In 16 bit operation, when -32,768 is reached the next incrementation will write a value of +32,767 to the (D).

Examples of the use of DECP instructions on Mitsubishi PLC :

1. If X000=OFF then Value in D0=30.
2. If X000=ON then Value in D0=29.
3. If X000=OFF then Value in D0=29.
4. If X000=ON then Value in D0=28.
5. If X000=OFF then Value in D0=28.

Writing the Inverter Parameters Mitsubishi PLC

Parameter writing is performed when the parameter number is stored to D9241 (D9243) and parameter writing value to D9242 (D9244), and turns ON the Y29 (Y2B). When writing is completed, X29 (X2B) turns ON to notify the completion. The device number within parentheses is used to write the parameter setting value to EEPROM. When writing the calibration parameter, set the following value to D9234 (D9235) to write each calibration parameter value.
0: Setting value (Frequency/Torque)
1: Parameter-set analog value
2: Analog value input from terminal

As soon as the inverter parameter write completion (X29(RAM) or X2B (EEPROM)) turns on, 0 is set to D9150 on normal completion. If an error occurs during access to the parameters, e.g. if any value outside the setting range is written or write is performed during inverter operation, the value of parameter No. + H8000 is written to D9150 as soon as the write completion signal (X29(RAM) or X2B (EEPROM)) turns on, resulting in abnormal completion. If abnormal completion occurs, the parameters are not written. For example, if an error occurs in the torque boost, H8000 is written to D9150.

Inverter parameter write must be performed in the PU operation mode or NET operation mode.

Inverter Status Monitoring of FR-A700 PLC

You can assign the data for grasping and changing the inverter’s operation status to D9133 – D9147 and read/write them from the user sequence.

The following data can always be read. They are automatically refreshed every time the END instruction is executed.

1. Operation monitor
The following data devices are always read- enabled (write-disabled) to allow you to monitor the output frequency, output current and output voltage of the inverter.

2. Error history (error codes and error definitions)
The inverter stores the error codes of the errors that occurred. The error codes of up to eight errors are stored in the order as shown below and are always read-enabled (write-disabled). Errors code storing method details as following:

• Alarm definition read program example.
The following program reads the latest alarm definition of the inverter to D0.

• Regarding the error No. and detail of the self diagnostic errors During execution of a sequence program, any of the following error No. is stored into D9008 due to an operation error. At occurrence of a self-diagnostic error, the P.RUN indication (LED) flickers.

Sequence Program Writing of Mitsubishi Inverter FR-A700 PLC

Sequence program write can be performed in any operation mode (external operation mode/PU operation mode/Network operation mode). When rewriting the PLC function parameters and sequence program using GX Developer, check the following:
1. Check that the sequence program execution key is in the STOP position (SQ signal is off).
2. Check that the inverter is at a stop.
3. Check that the communication specification setting parameters are set correctly. If any of these parameters are set incorrectly, communication with GX Developer can not be made.
4. Check the PLC series and sequence program capacity in the GX Developer parameters.
5. Refer to the GX Developer manual and write sequence program.

A sequence program can not be written with its step specified. If written, the sequence program does not run. The program outside the specified range is initialized.

Do not read the built in PLC function parameters and sequence program without writing them to the inverter once using GX Developer. Since the inverter does not have normal data, always write the built in PLC function parameters and sequence program once.

Since the built in PLC function parameters and sequence program are written to the flash ROM, there are restrictions on the number of write times, approximately 100,000 times.

1K steps or more can not be written. Number of steps usable when a program capacity is 1K steps are calculated as, 1 X 1024-2 steps = 1022 steps.

Counter C of Mitsubishi PLC Function Programming

The counters of the built-in PLC functions are up counters. An up counter stops counting and its contact turns on when the count value reaches the setting.
1. Count processing
• The coil of the counter is turned on /off at execution the OUT C instruction and its resent value are updated and their contact turns on after execution of the END instruction.
• The counter counts on detection of the leading edge (OFF to ON) of the coil. It does not count if the coil remains on.
2. Counter resetting
• The count value is not cleared even if the coil turns off. Use the RST C instruction to clear the count value and turn off the contact.
• When the counter is reset by the RST instruction, the present value and contact of the counter are cleared at execution of the RST instruction.

The counter counts on the leading edge of the input condition of the counter imported at an input refresh.

The maximum counting speed of the counter is determined by the scan time, and the counter can count only when the ON/OFF period of the input condition is longer than the scan time.
Maximum counting speed Cmax = (n/100) x (1/ts) [times/s]
N : Duty (%)
ts : Scan time [s]

Implementation of Neural Network Function Block

The implemented block is a three layer Perception neural network. The block includes three input nodes and seven nodes in second layer and one node in output layer. The block in PLC S7300 has two automatic and manual modes. In the manual mode the parameter of the network are declared manually in the program (W01…W21, B01…B21). They are set by the user when the network is used. However if they are not defined some uniform random number are selected. In the automatic mode parameters of the network are calculated automatically by the back error propagation training method.

It is the most conventional method for training of these networks. The network is completely trained after almost 10 minutes of the time which the PLC is placed in RUN mode (for 500 data for training). The training data should be sorted in some parts of the PLC memory and it makes a matrix with four vectors including three column vectors as the output date of the network. The input and output data are used for training the network parameters. Every training sequence is calculated in one machine cycle of the PLC system.

Below is diagram of Neural network block output compare to PID output:

To test the designed network in a Siemens PLC, the behavior of a PID controller for a first order simple model is studied in Matlab Software. The model is used to extract data to form four vectors, the samples are gathered from almost 8 minutes analyzing of the PID controller on the model with 1000 sampling points.

Configuring Modicon Telemecanique Quantum 140 NOE IP Address

Before you install your NOE 771 x0 (140 NOE 771 00 or 140 NOE 771 10) module, it needs to be configured with an Internet Protocol (IP) address which can be accomplished by either of the following methods:
• A new user configured IP address which you assign to the module.
• A default address which is derived from the MAC address appearing on the global address label located on the front of the module.

If a new IP address must be assigned, obtain it from your system administrator and then install it using your Concept Programming Panel. Alternately, you may use the BOOTP Server to install the IP address. In either case, record the IP network address on the writable area located on the front panel of the module.

If you use the default IP address derived from the MAC address proceed as follows: Locate the global address label on the front panel of the module. Convert them from hexadecimal to decimal. Each pair of hexadecimal numbers will result in a decimal number between 0 and 225. This is the default IP address.

The 140 NOE 771 x0 is capable of communicating over either an auto-sensing 10/100BASE-T or a 100BASE-FX Ethernet network at any given time, but not both at the same time.

Modicon Telemecanique Unitelway Network with G3

This article presents how to connect G3 HMIs on a Unitelway network. This network is using a proprietary protocol from Schneider telemecanique. The PLCs are also known as Square D or Modicon. As cabling particular for Unitelway, this note will describe on the connections between the HMI and the PLCs and between the PLCs.

As the Unitelway network supports only one master, both G3 will be slaves. Therefore the communication driver Unitelway Slave will be used in Crimson 2.0 configuration.

G3 Connections on the Network
In order to get data exchange, two cabling solutions are available:
1. Using the TER and AUX ports of the PLCs.
Telemecanique PLCs have 2 communication ports on the front panel. They are actually on the same network and can be used for easy connections to create the network.

2. Cabling as a unique bus
In this solution, cabling will be the same on a pin to pin point of view, only the connection point will be different. It will be as below:

In order to get this network up on running, the G3 have to be programmed as followed:
1. Select Unitelway Slave protocol.
2. Choose right Baud Rate, parity and stop bits as defined by the network.
3. Define the TSX as a Master.
4. Enter the G3 address on the network. This address has to be different from the others slaves and can not be 1, 2 or 3 as they are reserved by the master.
5. Indicate the address of the unit you wish to communicate with. An address of 0 will access the master. You can access other slaves as well if you enter their address.

Defining the Access Names of TELEMEC Server with InTouch

InTouch uses Access Names to reference real time I/O data. Each Access name equates to an I/O address, which can contain a Node, Application, and Topic. In a distributed application, I/O references can be set up as global addresses to a network I/O Server or local addresses to a local server.

The following fields are required entries when entering Access Name Definition:

1. Access Name
In the Access Name box type the name you want InTouch to use to this Access Name.
2. Node Name
If the data resides in a network I/O Server, in the Node Name box, type the remote node’s name.
3. Application Name
In the Application Name box, type the actual program name for the I/O server program from which the data values will be acquired. In case the values are coming from the TELEMEC Server the TELEMEC is used. Do not enter the .exe extention portion of the program name.
4. Topic Name
Enter the name defined for the topic in the TELEMEC Server to identify the topic the TELEMEC Server will be accessing.
5. Protocol to use
Select the DDE Protocol.
6. Advise Server
Select Advise All Items if you want the server program to poll for all data whether or not it is in visible windows, alarmed, logged, trended or used in a script. (Not recommended).
Select Advise only active items if you want the server program to poll only points in visible windows.

Telemecanique Dynamic Data Exchange (DDE) Server

The Telemecanique DDE Server is a Microsoft Windows application program that acts as a DDE (Dynamic Data Exchange) server and allows other Widows application program to access the data from the Telemecanique TSX17-20 micro PLC and its I/O extensions blocks. Connection requires a TSX17 ACC8 interface cable and a TSX 17 ACC11 connection kit with the 9 and 25-pin connectors. The data link is established by connecting TSX 17 ACC11 to the 9-pin serial port on the IBM PC and to the 25 pin connector on the TSX 17 ACC8 is set to the Series 7 position.

The DDE protocol identifies an element of data by using a three-part address, including Application, Topic, and Item.

Application refers to the name of the Windows program (server) that knows how to access the data element. For the TELEMEC server, the application portion of the DDE address is TELEMEC.

Topic is an application specific sub group of data elements. The TELEMEC server considers Micro PLC and uses this name as the topic name for DDE references.

Item indicates a specific data element within the specified topic. For the TELEMEC Server, an item is Input bit, output bit, System bit, Internals word, Constant word, System word, Input register word, output register word, bit of any word, parameter of function block.

Interface between Operating System and Interrupt Service Routine of PLC 135 WB

PLC 135 WB has interrupted processing capabilities. In this mode, the cyclic program in interrupted and an interrupt service routine executed. Once the interrupt service routine has terminated, the processor returns to the point of interruption and resumes execution of the cyclic program.

The interrupt service routine is initiated in two different ways:
• I/Os causing interrupt (OB 2).
• Signal state change of selected input bit (edge-controlled) (OB 3).

OB 2 and OB 3 constitute the interface between the operating system and the interrupt service routines.

Organization block OB 2
OB 2, the block with the highest priority, is called by interrupts of the process I/Os causing the interrupt. It can only be processed in special mode. The alarms are retained in flag bytes FY 8 to FY 10 and must be acknowledged by the user.

Organization block OB3
OB 3 is always invoked when the signal state of a bit in up to four interrupt input bytes changes. The user may select the input bytes and default it via machine data (PLC MD 124 to 127).

The system program checks the interrupt bytes every 10 ms, and invokes an interrupt service routine when required. OB 3, however, is only processed once per 10 ms scan, even, if several signal state change occur.

OB 3 can be processed in normal or special mode and has a lower priority than OB 2, e.g.
OB 3 can not interrupt OB2.

Modicon 800-Series Input/Output Modules

The Modicon 800-Series input/output offer one of the industries widest ranges of I/O modules. Their dependability has been proven in thousands of application worldwide. With over 50 modules to choose from, you can select the most cost-effective module for field device requirements.

The Modicon I/O family offers discrete, analog, special purpose and intelligent modules to meet the most demanding I/O and process control needs:

• Discrete In – which convert signals coming from field input devices such as push buttons, limit and proximity switches, or photo sensors into signals that can be used by the PLC.

• Discrete Out – which convert signals generated by the PLC into output signals used to control field devices such as motor starters, relays, lamps, or solenoids.

• Analog In – which convert analog signals coming from field input devices such as pressure, level, temperature, or weight sensors into numerical data that can be used by the PLC.

• Analog Out – which converts numerical data generated by the PLC into analog output signals to be used by field devices – such as heaters, valves, pumps instrumentation, or drives.

• Special Purpose – which handle unique signal requirements. For instant high speed counter, CAM emulator, RTD and thermocouple modules.

Modicon B882-239 High Speed Counter Module

The B882-239 High Speed Counter Module has two identical and independent counters for applications that require counting or comparisons. Because the module handles the counting within own internal logic, the PLC is free to do other tasks.

Each counter counts to 9999, and two counters can be cascaded to count to 99,999,999. Each counter counts up to 10,000 pulses per second. The module has two modes of operation, high frequency and low frequency, so its maximum count rate varies from 350 Hz (Low Frequency) to 30 KHz (High Frequency).

Because the module acts independently of the PLC, it counts the high speed pulses from the field independently of the PLC scan. The counter automatically reports its current count to the PLC every scan. Where high performance is required, the modules own outputs can trigger independently of the controller scan.

The major features of the B882-239 High Speed Counter Module include:
• Two independent counter (0 – 32 Vdc, true Low).
• 0 – 30 KHz operation with selectable low frequency filter.
• Six auxiliary field inputs (0 – 32 Vdc, True Low).
• Six Field outputs (0 – 32 Vdc, True Low).
• Self diagnostic.
Other specifications of Modicon B882-239 High Speed Counter Module are:

Basic Physical Configuration of Modicon 984 PLCs

Modicon 984 PLCs are designed as a compatible family, the individual products in the family offer a wide range of functionality and physical attributes. This means you can use the right PLC for the right job – no matter what application.

The PLC is available in three basics physical configurations: compact, chassis mount and slot mount. Slot mount PLCs use an advance microprocessor architecture that incorporates system and power components into single compact modules. These modules mount in the primary 800 Series I/O sub racks. They include the 984-38x series. 984-48x series, 984-685 series, and 984-785 series PLCs. These models cover small to large control applications with logic solve time ranging from 1.0…5 milliseconds/K of user logic. Slot mount PLCs are the perfect choice for small to large applications such as machine or process control.

Chassis mount PLCs are housed in rugged four or seven slot chassis. These PLCs comprise a set of modular system boards that are individually installed in slots in the chassis. Chassis mount PLCs include the 984A, 984B, and 984X models. These models cover mid range to extra large control application with high performance logic solve time of about 0.75 milliseconds/K of user logic.

On-Screen Cross Reference of SYSWIN

Select Block Cross reference command to display the Address Cross reference dialog. Using the Display options, you can choose to display the list of addresses used within the current network (Alt+F7) or you can display the complete list of addresses used within the whole program (Alt+F8). When you are editing the program in the ladder editor you can press Alt+F6 to quickly show the cross references for the current address at the cursor.

Find Address
You can quickly find the references for any address by typing in the Find Address field.

Previous/Current/Next
If you choose to display the address list for the current network, you can use the Next and Previous buttons to change the current network. If you have changed the current network by clicking on cross-references, you can update the Address list by clicking the Current button.

Go To
If you have a cross reference entry highlighted, you can close the Address Cross References and edit the current network using the ladder editor by pressing the Go To button. A quicker way to edit the current network is to double click on the highlighted cross reference entry.

Close
This button closes the Address Cross-Reference and returns you to the original network that you were editing before you started the Address Cross References.

Statement List Editor in PLC with SYSWIN

The actual PLC instruction code which underlies any ladder program can be viewed and edited with the Statement List Editor. It allows you to verify the contents of networks in instruction format, and make changes as necessary. You can use Statement List Editor to create an entire program, through the features of SYSWIN encourage more intuitive programming method using ladder diagrams. This editor is intended to enable the viewing and modification of networks when the need arises.

The Statement List Editor is opened with command from the Editors menu, or by clicking on the Statement List Editing button on the toolbar (Ctrl+F8). This dialog operates with the ladder display, so that when you move between networks, the ladder display moves too, and always shows the same network as selected in the editor. Use the Previous and Next buttons to step from one network to the next.

The Network and name fields from the current network header are displayed-the name field can be changed with the Network Symbol Editor.

The instruction list can be displayed in either address or symbolic format, depending on your selection for the Display option. If you have used the other editors to create symbol names for addresses, the information displayed here in Symbol mode makes it easier to follow the instruction listing. You can only change between display modes when the instructions are valid.

Instructions are entered as normal text, similar to Notepad. You can use the Windows cut, copy, paste tools (Ctrl+X, Ctrl+C, and Ctrl+V) in the usual way to edit the list, and the mouse to select items for coping or deleting. Ctrl+Z can also be used to undo the last change.

Entering Functions on PLC Projects with SYSWIN

All ladder programs use function in addition to the basic instruction. These are entered in much the same way as symbols, but because most of them require data parameters on which to operate, the process involves different dialogs.

SYSWIN uses your setting of the PLC type, together with your function mapping parameters to determine which functions are available to use. When a function is selected, a dialog box is displayed requesting the necessary data.

If you know which function you wish to insert in a network, the easiest way to enter it is to use the ‘F’ key. This displays the function dialog box, and you can type in the name or number of the function.

When a function is drawn, its inputs (and occasionally output) are indicated by unterminated lines. These need to be connected to other parts of the network before the network is complete.

Most functions are available in differentiated and non-differentiated forms. They identified by special symbols in front of the name. When a function can have more than one form, the dialog provides extra check boxes. Alternatively, you can use special characters when typing a function name, and SYSWIN converts the function as appropriate:
• @ Differentiate UP
• % Differentiate DOWN
• ! Immediate refresh

The availability of differentiated functions, contacts and outputs depends on the PLC type.

Program Structure of SYSWIN in a PLC Project

Although it is possible to create a program that consists of a simple series of networks, SYSWIN encourages you to break down a program into groups of networks, which form functional blocks.

The concept programming in block is designed not only to make it easier for you to work through a program, by splitting it into manageable chunks, but also to maintain the program after it has been in use for a while. Programming in blocks also eases the process of creating library modules that can be incorporated into future programs.

SYSWIN encourages the creation of groups of networks within blocks, again promoting the concept of working in a structured manner, as shown in this example:

With CV series PLCs, interrupt routines are held in separate blocks, and main blocks are sequential and joined together. For both C and CV series, the last block in main program must contain the END instruction, as normal.

Normally you would not be connected to the PLC when preparing the main structure of a program. After programming you would check the program carefully before connecting and downloading it to the PLC. Checking of program syntax and validity of function is done by SYSWIN at various times as a protective mechanism, but any logical checking that you do speed up the debugging process.

Ladder Programming Workspace of SYSWIN

The main area of the SYSWIN screen is devoted to the ladder program display, as a window covering part of the total programming workspace. To view larger portion of the workspace, you can use Preferences Overview Mode command-selecting this same command again switches back to normal mode.

When first running SYSWIN, or opening a program you always see the left-hand ‘rail’, from which ladder program networks always begin. A right-hand rail exists in workspace, at its extreme right, but this is normally off the screen. When you complete the network, outputs are drawn showing a small vertical bar to indicate the right rail. This saves having to scroll the display to see the right-hand side of your networks.

The currently selected network is generally displayed at the top left of the workspace window. The left-hand side of the power is highlighted and the program scroll as you move up and down between networks. SYSWIN has a keyboard interface that allows the Up and Down arrow keys to roll up and down between networks. Page Up and Page Down keys scroll the screen by full pages. Block Insert Network command (Alt+Insert) enables you to create a new network, above or below the selected one. Using the mouse, double clicking on the left side of current network bar, if visible, insert a new network above it.

Setting up a PLC Project with SYSWIN

When planning a PLC programming project, various item need to be considered and setup within SYSWIN before beginning to lay down program instructions. Once set for a project, it is not advisable to change the PLC, and preparation of an initial specification for the program is therefore recommended.

Before programming, it is recommended that you make up a checklist of the important program aspects, including its structure and PLC parameters. To start a new project in SYSWIN, you should follow these steps in addition to the basic procedure outlined in your PLC programming manual:

• Determine essential parameters of the PLC.
The SYSWIN project setup needs to know:
PLC series (C or CV).
PLC type (C200H, CQM1, etc).
CPU (where applicable).
Type of communications interface.
Your choice of editor and project type.

• Assign specific project information.
Text information should be provided.

• Check the project preferences
Determine how you want the project to be displayed, and how the statement list code is to be generated.

• Allocate PLC memory
Work out the balance required between program memory and expansion data memory.

• Establish the PLC setup parameters.
Configure the parameter necessary for the desired way of running the PLC.

• Create the appropriate I/O table.
List all I/O devices and addresses related to them.

• Create a basic structure for the program.
Note how you plan to group functional networks to make up program blocks.

• Decide how to input and edit the program.
SYSWIN offers two main methods of working on a program: ladder diagram and function plan.

Once those are completed, the appropriate files are copied to your hardware or the network drive. If necessary you are prompted to insert other program diskettes when the software requires it.

SYSWIN V3.4 can also be fully activated using a token or dongle from previous version of SYSWIN.

Installation of PLC Driver Siemens LOGO!

The PLC driver can be installed while PLC-ANALYZER pro is operating. Select the PLC driver in menu Extras. In the widow PLC driver click the button Add. If the desired driver is not on the list, you have to install a new driver via the License-Key management.

With PLC-ANALYZER pro you can load the same or different PLC driver more than once to acquire data from different PLC.

Installing Additional Hardware
If you have connected your PC with LOGO! Using LOGO! (USB) PC cable, usually nothing else must be done.

Installing Additional Software
No software is required in addition to the PLC-ANALYZER pro basic module and the PLC driver.

Configuration of PLC Driver
After installing the driver you can change important parameters under Properties.

Choose meaningful name for the driver first, and then specify under Connection the Com-Port of the PLC, which is connected by a cable to the PLC. Press Test Connection to check whether a connection to the PLC can be established.

Use Time Stamp to specify, if the time stamps should be entered into the signal file continually or only signal changes. For a continuous time stamp the exact scan points are documented even for a signal which does not change.

Under Scan Interval enter the length of time between read-out of data from the PLC. A longer scan interval may be chosen for non critical time signals.

The Benefits of Conversion RS Logix 500 to RS Logix 5000

The conversion programming from RS Logix 500 to RS Logix 5000 seen versatility alone could make the conversion from the RS Logix 500 platform to the RS Logix 5000 platform a worthwhile venture. With four different programming languages at your disposal, almost every electro-mechanical control application conceivable can be accomplished through the implementation of Rockwell Software’s RS Logix 5000 software.

Due to the multiple programming languages, it was able to be shortened. Each programming language has a topic that it has been designed for. With this in mind, the Ladder logic pertaining to the heating zones was more suitable for function block diagrams than Ladder logic. The commands are more suitable to particular applications, therefore, shortened the code.

Another benefit is having the ability to program all inputs and outputs using descriptive tags. It was obvious through the project code writing processes that a program with tags would make a program not only easier to follow, but easier to troubleshoot too. Additionally, the ability to monitor and change tag values, while the program is online, has been a benefit. For example, gain values for a PIDE function block can be changed online to optimize your PIDE curve. The result of this tuning can be seen almost instantaneously and will not disrupt the other program functions.

Set Up EthernetIP for ControlLogix 5000

EDS file is an Ethernet IP EDS file specific to PumpSmart PS200 is available on the PS200 v5 Fieldbus Communications web page. Note that EDS files are only required when using RSNetworx for Ethernet in your application. This example is not using RSNetworx for Ethernet but is opening a generic Ethernet module in the ControlLogix 5000 PLC.

1. Open RS Logix 5000 and open an RSLogix 5000 program. Right click on the 1769-L32E Ethernet Port Local ENB.

2. Click on new Module.

3. Select module Ethernet – Module

4. Program the following information below. The example below is using Input and Output Assembly instances 102 and 103. Once completed click finish.

Input and Output sizes must match that used in the PS200. If writing to the Control Word and first reference, and reading the status word, motor speed, power, and smart flow, the output size must be 2 and the input size must be 4.

5. The RETA-01 is now added to the PLC I/O.

The problem or error that usually happened is unable to establish communications between the drive and the DCS (PLC). To avoid this problem:
• Be sure the module is located in slot 1 of the PS200.
• Check the MAC Addressing between the DCS and the drive specifically the IP and Subnet Mask.
• Be sure the Comm Rate and DHCP values are correct for the network.
• Be sure that parameter 31.01 state RETA-01.
• Be sure that you have refreshed the fieldbus module anytime after you change parameters in group 31.27.
