The Benefits Simulation Tool Control RTU (Remote Terminal Unit) SCADA (Supervisory Control And Data Acquisition) SM800-Based Programmable Logic Controller




With the advance of technology the Intranet and the Internet today, SCADA concept has become more simple and utilize the Intranet infrastructure. At the beginning, the control system has a device MTU (Master Terminal Unit) which has function as Control and Data Acquisition through one or many RTU (Remote Terminal Unit) which serves as a (dumb) Remote I / O via communication lines radio, dedicated line Telephone, etc.

In some industrial applications, Telemetry Products from NBT consisting of The SM800 Series Telemetry PLC combines the functions of a data logger, programmable logic controller, and the controller communication into one powerful, cost-effective unit. RTU (Remote Terminal Unit) has several important roles in performing the function of Control capability, Recording capability, Alarming capability, Direct reports and alarms to PC, fax or pager.

Telemetry Hardware SM800 Series PLC

Accurate and Easy Data Logging Process

Telemetry capability is no doubt in terms of Data Logging - The SM800 is able to continue to track the performance of the equipment or process for a certain period. Capacity data logging device is capable of tracking unit 5600 stores the event (22,000 optional) including date and time stamp and the data can be transferred to Microsoft Excel, Access or DDE compatible software. This facilitates the reading and analysis of data.


Remote Monitoring and Control Capability

One of the functions carried this device is to monitor various points in a single piece of equipment, a complex process, or a complete facility. Remote Process Monitoring & Control - SM800 is relatively fast and sophisticated as it can perform real-time control and / or program the unit to control every point in the system and has control based on arithmetic calculations such as Min. / Max, run times, etc.


Fast and Secure Communications Device

Fast data communication, without delay and accurate strongly support the performance of the system. The device is powered by three communication ports in each unit: two standard RS232 and RS485 a good, RS422, RS232, telephone or radio modem. Configuring the system becomes easier in a hierarchical network in which the remote unit can communicate with each node as other intelligent network. This allows to be configured in a system. Another advantage is the ability of peer-to-peer SM800 allows the remote unit to call other units are timed and / or alarm conditions.


Alarming Early Warning System

As the media early warning system, an alarm is very important function in the control system. This device is equipped with an automatic alarm system work with SM800 send a notification so that corrective action can be taken in the event of system error. Alarm call system can be up to six digits, including PC, FAX and pager. Users can choose one of seven different report formats for direct reporting of each FAX.


Having Functional and Versatile

The control device has versatile functions, as well as internal programmable logic controller and serves as a BASIC compiler allows the user to perform almost any data calculations are fast and scalable. No need understanding of complex programming languages, user friendly programming with "Fill Empty" spreadsheets easy to understand. After completion programmed, the connection to the equipment can be done with a simple process.


Proven and Supported Device Control System

Users do not need to hesitate to use this device because it has a lot of companies that use and supported by thousands of units in service for government agencies, utilities, OEM, Engineers and Integrators. Many applications in the industry SM800 perform a variety of tasks from the water and wastewater systems for site remediation monitoring, data logging and alarming.


Many Alternative Base I / O Options

Users have many choices in using the base I / O for example Basic I / O options, 2 Digital In, Digital Out 2, 4 Analog In, Digital In 4, 3 Digital Out, 1 Analog In, 1 Analog Out. To meet customer needs, the device also features Expansion: Up to 15 I / O Module, Expansion Module Available, 8 Pt Digital In, 8 Pt Digital Out, 16 Pt Digital Out, 8 Pt Analog In, 4 Pt Analog Out, 4 pt Free Counter, 4x20 Display / Log Interface Module.


Conclusion

RTU (Remote Terminal Unit) SCADA (Supervisory Control And Data Acquisition) SM800-Based Programmable Logic Controller can be used via the configuration architecture with low cost remote I / O using a leased line, dial radio modem or wireless connection. Ease of use and the many benefits obtained The SM800 and SM300 Series is fully compatible with each other and have been used together in a variety of telemetry applications make the device widely used.
