(2) Error codes returned from PLC CPU, intelligent function module and network board.
The following explains the error codes returned from the PLC CPUs, intelligent
function modules or network boards.
POINT
The error codes may not be returned as described in "(a) Error code list."
Before referring to "(a) Error code list", read "(b) Precautions for error code
confirmation."
(a) Error code list
When an error is detected by the PLC CPU, intelligent function module or
network board, the following error code is returned.
The higher two bytes indicate an error detection module, and the lower two
bytes indicate the error code returned from the module where the error is
detected.
For details of errors, refer to the manuals of the PLC CPU, intelligent function
module or network board corresponding to error codes.

(b) Precautions for error code confirmation
The following describes the precautions for error code confirmation returned
from the PLC CPU, intelligent function module or network board.
1) Property setting error
When the system configuration does not match with the property value
setting, the higher two bytes cannot indicate the correct error detection
module.
For example, when the ACPU's property value is set to ActCpuType in the
QCPU (Q mode), the higher two bytes may indicate the ACPU as an error
detection module.
In such a case, communicate again after confirming the system
configuration and all the property value settings.
In addition, when using the ActMulti or ActMLMulti control, confirm the
setting of the communication setting utility.
