Ethernet Connection in the Operator Panel
In some industrial units for Ethernet, the RJ45 contact's shield is connected to the
chassis via a capacitor, see 1 in drawing above.
The operator panel's Ethernet shield is directly connected to the chassis, see 2
in drawing above.

In many cases, connecting the shielded Ethernet cabling to the chassis at both
ends is inappropriate. Hum or grounding loops can occur. Unshielded cabling
may even result in fewer communication errors.
If using a HUB on the LAN B port results in different issues, like bad
performance, then it is recommended to use Switch instead of HUB.

Check whether the other Ethernet unit has its shield directly grounded or
grounded via a capacitor.
