The Top 5 Siemens Modular PLC

In the world of control system we know some brand PLC, such as modular PLC that already become one module. For example the PLC Omron its devices already incorporated into one between I / O, CPU and Memory. While the example of Siemens and Allen-Bradley modular appliances so that its device components separately, between the CPU, IO and memory, which is incorporated in a single rack. At this session we will discuss the following picture of Siemens Modular PLC as below:

Siemens Modular PLC Controllers

1. Logic module LOGO!

This type controller widely used for simple automation tasks in industry and building service.  Logic module LOGO design is very flexible, but allows expansion to advance the controller 24 digital inputs, 16 digital outputs, 8 analog inputs and 2 analog outputs! Although it has a simple design but the controller is already compatible with AS-Interface and KNX. One use is for heating and cooling system design with the RTD PT100 module using PI control, the response and analog multiplexer.

2. SIMATIC S7-1200

SIMATIC S7-1200 controller can work perfectly together with HMI, I / O, drives and software to create a custom-designed system controller. This controller can be integrated into the Totally Integrated Automation (TIA) easily, flexible and scalable. Simple and flexible design allows you to optimally meet specific needs, and to expand the system securely.
SIMATIC S7-1200 controller is compatible with PROFINET IO, the SIMATIC S7-1200 and fit to be used together with PROFINET IO devices to solve a variety of applications - the power of "SIMATIC"

3. SIMATIC S7-300

Modular controller becomes the latest solutions for system control in the manufacturing industry because it is easily and widely in use with the product range comprises 7 standard CPU, a compact CPU 6, 6 CPU fail-safe and 2 CPU technology. CPUs are available from a width of only 40mm.

4. SIMATIC S7-400

SIMATIC S7-400 is the advance variance of SIMATIC device controller that is expected to perform the function control in the manufacturing and process industries to more quickly and accurately. This controller is an advanced all the CPU that controls the workload in large quantities. Even several CPUs can work together in a multi computing configuration to boost performance quickly. This CPU has a work memory, address range, number of connections and good execution time so as to perform high processing and deterministic response time which is great

5. SIMATIC S7-1500

The last version SIMATIC SC-1500 is a new generation of controllers in the Totally Integrated Automation (TIA) Portal and milestones in automation. By using this product you will get 2 advantages namely: Power plus and Efficiency Plus.
  1. Power Plus Advantages:
  2. SIMATIC S7-1500 has a high-quality system performance and fast response time. The technology used has integrated perfectly with the motion control functions and PROFIdrive.
  3. Efficiency plus Advantages:
  4. Innovative design and easy trouble shooting makes this device safe and comfortable to use. Ability in the diagnosis of an integrated system automatically and consistently make your investment in the design of control system will generate good returns.


Siemens Modular PLC is an electronic circuit that can do a variety of functions in the control of complex levels. It can be programmed, controlled, and operated by an operator who is not experienced in operating a computer. This controller is generally depicted by lines and equipment on a ladder diagram. Results of program on a computer illustrates the control flow that have output is to be ON or OFF. It can also be operated in a system with varying output. You can choose type of controller based on control system complexities.
