Network: timeout explicit message

What does 0x8112 mean?

This warning indicates that no "explicit message" was received within the parameterized timeout period set by the scanner, or the connection to the scanner has been interrupted. This points to an issue with explicit network communication or its physical connection.

• Loss of network communication between the inverter and the PLC/scanner due to a broken cable, loose connector, or faulty network switch.
• Incorrect network address (e.g., IP address, node ID) configured on either the inverter or the PLC/scanner.
• PLC/scanner experiencing a fault or being in a stopped state, preventing it from sending explicit messages.
• Incorrect network timeout settings (e.g., P800.00, P801.00) in the inverter or scanner, causing premature timeouts.
• Network traffic congestion or interference, delaying explicit message delivery beyond the timeout period.

Click steps to track your progress.

1. 1

   Verify the physical network cable connection (e.g., Ethernet cable, CAN bus) between the inverter and the scanner. Check for proper seating and damage.

2. 2

   Confirm that the network address (e.g., IP address in P800.00 or node ID in P801.00) configured in the inverter matches the scanner's configuration.

3. 3

   Check the status of the PLC/scanner to ensure it is running and attempting to communicate with the inverter.

4. 4

   Increase the network timeout parameter (e.g., P802.00) on the inverter or scanner in small increments to allow for network delays.

5. 5

   Monitor network activity using a network sniffer tool to identify communication drops, excessive traffic, or message delays.
