- 1
Inspect communication cable connecting the remote node to the PLC communication module for physical damage, proper termination, and secure connections at both ends.

Verify that the remote node is powered on and measure its supply voltage at the input terminals to ensure it is within specified operating limits.
- 3
Check the status indicator LEDs on both the remote node and the PLC's communication module for network activity, power, and error indications.
