The hybrid motor starters are connected to PROFINET via the EMPNET-GATEWAY-IFS. Connection is via a DIN rail connector, which provides the 24 V supply voltage and is also used to control the devices. Digital outputs are not required in order to control the motor starters. The motors are safely shut down via enable inputs using a safety relay or safe controller according to PL e. The EM-PNET-GATEWAY-IFS has eight digital inputs and four freely programmable outputs. Particularly in the case of a modular or distributed structure, there is no need for I/O cards at the controller or even remote I/Os.
In this case, the position switch is connected directly to the PROFINET gateway.
The hybrid motor starters, as well as the command and signaling devices, are directly connected to the controller via a gateway using SmartWire-DT™. SmartWire-DT™ reduces the wiring effort. You benefit from clearly arranged and compact control cabinets. Safe shutdown is implemented with a PSR safety relay.
