4.3 Connecting the connection module CM CPU 2PN M12 7/8"
Introduction
Connect the supply voltages and PROFINET to the connection module
CM CPU 2PN M12, 7/8". The 1st PROFINET interface (X1) is equipped with an internal
PROFINET switch. This enables the direct loop-through of PROFINET or the direct
connection of another IO device (e.g. ET 200pro with IM 154-4 PN). Use X1 Port 1 and X1
Port 2 for configuring ring topologies. The 2nd PROFINET interface (X2) has only one port.
