An action to be taken when an I/O data error has occurred depends on the error cause stored in Error code
details 1. For details, refer to the following.
• All input points error: If an error occurs for all the input points due to the input dark test error (error code:
0205H) or the double input discrepancy detection error (error code: 0204H) and the input function cannot be
performed anymore, a moderate error state of I/O data error (error code: 010BH) is applied. In such a case,
take actions to restore from the previous error state (0205H or 0204H: minor error).
• Error detected by internal input dark test: Correct the wiring on the error detection points indicated in Error
code details 2.
