The system detected an unexpected routing error. The manual's first action is: “Check the routing tables.”
The local node is busy and cannot send data. The manual's first action is: “Change the network so that traffic is not concentrated.”
Illegal packet discarded due to invalid data transmission. The manual's first action is: “Check for nodes sending illegal packets.”
Internal buffers are full and packets are being discarded. The manual's first action is: “Change the network so that traffic is not concentrated.”
The system failed to send a command due to a header error. The manual's first action is: “Check the command format and set the correct command data.”

The system encountered a routing table error while attempting to send data. The manual's first action is: “Create the routing tables correctly.”
The system failed to send data because no routing table entry was found. The manual's first action is: “Set the local node, remote node, and relay nodes in the routing tables.”
The destination address is not in the routing tables, so data cannot be sent. The manual's first action is: “Set the destination address in the routing tables.”
The CPU Unit failed to send a signal successfully. The manual's first action is: “Troubleshoot the error in the CPU Unit using the PLC operation manual.”
The system failed to find a unit at the specified address. The manual's first action is: “Check the unit address at the remote node.”
The remote node is not connected to the network and communication failed. The manual's first action is: “Check the connection to the remote node.”
The system has failed to send a command due to resend count exceeding limits. The manual's first action is: “Check transceiver at remote node.”
