Integration into fieldbus systems is implemented using the INTERFACE system connection or the SmartWire-DT™ wiring system. Corresponding gateways are available for all common fieldbus systems.
The hybrid motor starters are connected to PROFINET via the EM-PNET-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 to control the motor starters. The motors can be 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 parameterizable 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 switches are directly connected to the PROFINET gateway, for example.
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.
