Ethernet port isolation is designed to limit hazard during short term network faults to hazardous voltages. It does not
conform to safety requirements for routine AC line voltage isolation.
Note
The CPU models CPU C
R20s, CPU CR30s, CPU CR40s, and CPU CR60s have no
Ethernet port and do not support any functions related to the use of Ethernet
communications.
