Interface settings

Interface settings 1:

Is only available on the EK9320 and the EL6633.

Service protocol:

The service protocol used for the acyclic services can be manually selected here. The SystemManager recognizes which protocol is supported based on the GSDML of the device.

RPC:

RPC uses the UDP protocol as the transport layer. This requires the assignment of an IP address, which is limited to IPv4 in PROFINET.

RSI (default):

RSI only uses layer 2 communication, all services that are used with RPC via UDP are routed via layer 2 communication with RSI. This means that no IP address is required and none is assigned via PROFINET by default.

RSI with IP set:

RSI is used as the service protocol, but the PROFINET device is also assigned an IP address by the controller via DCP during connection start-up. This means that the use of IP protocols or services (e.g. SNMP or WebServer) is still possible without the need for an additional "IP assignment mechanism".
