Through its many innovations, the new SIMATIC S7-1500 controller sets new standards for maximized productivity. This benefits a range of machines including small-series machines as well as more complex installations. The SIMATIC S7-1500 is seamlessly integrated in the Totally Integrated Automation Portal(TIA Portal) for maximum engineering efficiency.

The SIMATIC S7-1500 is modularly structured, with scalable functionality.

Each controller consists of

  • CPU:
    The CPU is the heart of the system.  They execute the user program and network the controller with other automation components.
    Thanks to multiple innovations, the new Controller will provide the ultimate “plus” in productivity and efficiency. There are a range of CPUs available that can be chosen based on the kind of application that we are using it for. Cotmac has the ability to advise and implement the right kind of combination for any specific automation solution
  • Signal modules as inputs/outputs:
    The signal modules or I/O modules provide the interface between the controller and the process. The controller detects the current process status by means of the connected sensors and triggers the corresponding actuator reactions. With rich experience, Cotmac Electronics personnel have developed the skill to use the right combination of equipment to give optimal results
  • Technology and communication modules :
    Technology modules (TM) offer hardware-level signal processing for rapid counting, measurement and position registration for a variety of encoders. While communication modules increase the communication capabilities of the S7-1500 through additional communication functions or more interfaces.. Additional interfaces enable realization of complex automation structures or process optimization through connection to the enterprise management level.
  • HMI :
    SIMATIC HMI is optimized to meet your specific human machine interface needs using open and standardized interfaces in hardware and software, which allow efficient integration into your automation systems.
  • And Safety? It’s integrated in the F-modules, of course!

Some Innovative features of S7-1500 PLC

Use of 1500 controller ensures highest efficiency, and maximum usability for medium and high-end applications in machine and system automation.

Diagnostics Display

Main aggregate of 1500 PLC is troubleshooting through color display

S7-1500 PLC provides Color display for easy access to detail diagnostics.  User need not to go in software option for checking error. This will reduce the time required to diagnose the problem by providing complete plant transparency.

User can do many more settings in display of 1500 PLC like setting IP address of the hardware device,


S7-1500 has facility to protect the display so that unauthorized person will not be able to access the PLC Program & parameter settings.


To meet the evolving needs of various industries fail-safe versions of the controllers are used that will better enhance every production process. Fail-safe CPU’s execute both standard programs and safety program as well. So need for separate safety PLC’s is eliminated.

STEP 7 language innovations

Only limited languages are supported by predecessors of 1500 but in 1500 Controller total 11 languages are supported for programming as well as for color Display.

Potential Bridges:

Integrated Potential bridges for flexible potential group formation reduces the wiring cost.

Shared Device Functionality

One I/O device can be shared by more than one controller for e.g. A Drive and a safety controller can share one IO device. One interface is sufficient for both clock-synchronous control of the drive and fail-safe communication.

Industrial Automation continuously demanding fast response time of the system in order to increase production efficiency & to reduce downtime of the Plant.

S7-1500 is the best solution to achieve all those requirements by providing response time less than 900 micro second.

Cotmac Electronics has been designing Automation systems using the S7 1500 PLC for many projects and has a superior understanding of the system. This enables better design and makes for efficient and seamless automation systems
