Troubleshooting using the engineering tool

Check the error or history using the engineering tool, and identify the error cause. More detailed information on the error as 
well as the error cause and action to be taken can be checked by using the engineering tool.
The engineering tool has the following functions for troubleshooting.

This function diagnoses CPU module, expansion adapter, and expansion board. (The current error and its details can be 
checked.)
Information required for troubleshooting, such as the current error, details and cause of the error, and action to be taken, are 
displayed. The incorrect parameter setting and program error location can also be identified by selecting the error and clicking 
the [Error Jump] button. On the [Module Information List] tab, the LED status and the switch status of the target module can 
be checked.
