Simatic S5 6eS5-1XX PLCs & 6EP-XX Programmable Logic Controllers

Simatic S5 6eS5-1xx & Simatic 6ePXX PLCs (programmable logic controllers) are not like any average programmable logic controllers. These controllers don't just perform open-loop control these days, they also handle closed loop control, positioning, counting proportioning, valve control and much more. For this purpose, there are intelligent I/O modules built within the controllers. These PLCs are microprocessor controlled and execute time-critical special tasks completely automatically.

They also have a direct connection to the process via their own input/output channels. This avoids additional loads for the CPU. If it is necessary to bridge large distances between the process and the I/O modules the wiring can become very complex and susceptible to faults. If a modular and flexible automation system is required, we recommend use of distributed I/O systems.
