Connections on bus module
The bus module includes the PROFINET connections (X3 and X4) and the power
supply connections (X1 and X2). Depending on the version, connection is made via
push-pull plugs according to IEC 61076-3-117, variant 14 or 7/8"-plugs according
to ANSI/B93.55M-1981 and M12 plugs (d-coded) according to IEC 61076-2-101.
The bus module includes a PROFINET RT switch for Ethernet connection.
