12.7.2 Interface Connection
12.7.2.1 Default setting for an interface connection
In SafetyDesigner, different areas of the FSoE slave addresses and connection IDs must be
set for all projects of PLCs communicating with each other (in the example 1001 to 2000).
The areas must be unique system-wide for each PLC and must not overlap.
12.7.2.2 General Information on interface connections
In this type of connection, there is a payload data flow only in one direction per interface
connection.
In the SafetyDesigner project of the PLC providing the data, a write interface variable is
created where as a structure is defined which signals are to be transmitted via this
connection. Furthermore, which SCP this package provides and how many remote peers
should be supported (how many safe CPUs get the same safe signals).
