Problem:
Many modern automation systems are characterized by the following features:
- S7 CPU and ET 200 distributed I/O, connected over the Industrial Ethernet / PROFINET IO bus
- Safety program and standard program in the same S7 CPU
- Normal signals (e.g. Switch motor on) and safety-related signals (e.g. Emergency-off motor) are transferred over the same bus
For many applications, wireless communication is more cost-effective than communication using cable. In some cases, it is the only way of connecting an S7 CPU with distributed ET 200 stations. This applies, for example, to communication between moving parts of an automation system or between areas that are difficult to access.
Solution:
The following functionality is implemented using wireless (PROFINET IO over IWLAN):
- Normal switching duty of a motor (start, stop)
- Safety-related motor switch-off (emergency stop)
- Safety function (emergency-stop) in SIL 3 / PL e
Standard and safety-related communication thus takes place via IWLAN. The safety-related communication complies with SIL 3 / PL e. This is enabled by PROFIsafe. The following hardware components are used in the functional example, as well as standard components:
- Safety-related components: SIMATIC Safety Integrated for Factory Automation
- Components for IWLAN: SCALANCE W
