Wrong Station Number

What does 5000 mean?

This fault implies that the system is attempting to communicate with a device using an incorrect network station number. The target device cannot be reached because its identifier does not match what the system is sending, preventing proper addressing and communication.

• Incorrect station number configured in the communication message.
• Physical DIP-switch settings on the target device not matching configuration.
• Duplicate station number on the network, leading to ambiguous addressing.

Click steps to track your progress.

1. 1

   Verify the configured network station number or IP address within the PLC's communication instruction or module settings (e.g., MSG instruction, I/O configuration) matches the target device's expected identifier.

2. 2

   Verify the actual network station number, Node ID, or IP address physically set (DIP switches, rotary switches) or software-configured on the target device matches the value the PLC is sending.

3. 3

   Inspect the network cabling (e.g., Ethernet, DH+, RIO, ControlNet) between the PLC communication module and the target device for secure connections, damage, and proper termination.

4. 4

   Check the network status indicators (LEDs) on both the PLC communication module and the target device for any error conditions or communication faults.
