Remote Node Missing or Disconnected

Was bedeutet 3000 ?

This error occurs when a remote device or node that the system expects to communicate with is either missing, physically disconnected, or has been intentionally shut down. This prevents any data exchange or control operations with that specific remote node.

• Physical disconnection of the remote node's network cable.
• Remote node powered off or in a shutdown state.
• Remote node configuration mismatch or removal from the network.

1. 1

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

2. 2

   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. 3

   Check the status indicator LEDs on both the remote node and the PLC's communication module for network activity, power, and error indications.

4. 4

   Verify the network address (e.g., IP address, MAC ID, node address) configuration of the remote node matches the PLC's project configuration.
