Instructions That Read Function Module Error Status
You can determine the error status with the instructions that get error status provided for each function
module from the user program. These instructions get the status and the event code of the error with
the highest level.
Applicable function module
PLC Function Module
NX Bus Function Module
Motion Control Function Module
EtherCAT Master Function Mod-
ule
EtherNet/IP Function Module
Note An NC Integrated Controller has the CNC Function Module. For how to check and correct errors in the CNC
Function Module, refer to the NJ/NY-series NC Integrated Controller User's Manual (Cat. No. O030).
For details on the instructions that get error status, refer to the NJ/NX-series Instructions Reference
Manual (Cat. No. W502).
Checking with System-defined Variables
You can check the Error Status variable in the system-defined variables to determine the status of
errors in a Controller. You can read the Error Status variable from an external device by using commu-
nications. Refer to the NJ/NX-series CPU Unit Software User's Manual (Cat. No. W501) for information
on system-defined variables.
