3.34 Module Error Collection
3.34 Module Error Collection
This function collects errors occurred in the connected intelligent function modules in the CPU module. By storing the
errors in a memory that can hold data in the event of a power failure, the errors can be held even after power-off or
reset.Note 3.22
(1) Supported modules
The CPU module collects errors occurred in the connected intelligent function modules
*1
.
The CPU module does not collect the errors of intelligent function modules on other stations in the network.
*1 Indicates intelligent function modules that support this function. For supported module versions, refer to the manual for
each module.
(2) Timing when module errors are collected
Module errors are not collected during execution of a program such as the COM instruction but collected in END
processing.
Note 3.22
Before executing the function, check the versions of the CPU module and GX Works2 used.
( Page 465, Appendix 2) GX Developer cannot display module errors.
