CAUTION: ControlEdge PLC-I/O network is a private network, and
the switch used for the interconnection of CPM and EPM must
not be connected to any other LAN or WAN. Likewise, no devices
or communication traffic other than the ControlEdge PLC
components should be connected to the I/O network switch.
Failure to comply will cause communication failures on the I/O
network causing I/O modules to go in and out of their failsafe
settings.
