Chapter 12 Monitor Status and Handle Faults
EM Transmission Error
(Destination Device Absence) Unable to transmit because the destination
device is not on the network. Check the node address of the destination node and the node address of the transmission
message.
Make sure the power supply voltage for the destination node is set within the specification
range.
Make sure the communication rate of all nodes is the same.
Make sure the cable lengths of the main and branch lines are not too long.
Make sure a cable or wire is not disconnected or loose.
Make sure terminating resistance is at both ends of the main line and only at both ends.
Take precautions against excessive noise.
EM Transmission Error
(Destination Buffer Full) Unable to transmit because the destination
buffer was busy. Check the message receive size at the destination node.
EM Transmission Error (Command
Length Error) Unable to transmit because the command is
longer than the maximum length. Check the response message size from the destination. Also check if the response size expected
in the request message is correct.
EM Transmission Error (New
Request Received) Message was deleted due to receiving new
request. None.
Received Error Response (UEM) Receiving an error response when the user
explicit-message function is used. Check that the specified service or data size in the user explicit message matches the destination
object specifications.
Table 21 - DeviceNet Communication Error Messages
Message Description Corrective Action
Table 22 - EtherNet/IP Controller System Failure Error Messages
Message Description Corrective Action
System Failure A system failure occurred. Cycle the power supply. If a failure occurs again, replace the controller.
An EtherNet/IP memory error occurred.
An EtherNet/IP communication controller error occurred.
The same IP address is set for another device on the network. Check the IP addresses of the other devices, and set an address that does not
duplicate any other.
A setting table logic error occurred. Check the configuration. If a failure occurs again, replace the controller.
A BOOTP server connection error occurred. Make sure the cable is connected correctly.
Make sure the BOOTP server is operating normally.
An EtherNet/IP basic setting logic error occurred. Check the configuration. If a failure occurs again, replace the controller.
An EtherNet/IP standard target communication error
occurred. Make sure the same communication settings are used for each node.
Make sure the cables are not disconnected or bent.
Make sure the power is supplied to the originator.
A Link Off error occurred. Make sure the same communication settings are used for each node.
Make sure the cables are not disconnected or bent.
Make sure the power is supplied to the hub.
Table 23 - Error Messages Related to the I/O Power Supply
Message Description Corrective Action
Input PS Voltage Low I/O power supply (V1, G1) is not connected. Make sure the power supply voltage is set within the specification range.
Make sure that a cable or wire is not disconnected.
Output PS Voltage Low I/O power supply (V2, G2) is not connected.
