FEn (D): Diagnostics input n
The arrows indicate the permanent relationship between signal and diagnostics
input.
The following applies in the example:
Diagnosis for channel 0 (DI) is in bit 0 of byte 1 of the PII
Diagnosis for channel 1 (DO) is in bit 1 of byte 1 of the PII
Diagnosis for channel 2 (DI) is in bit 2 of byte 1 of the PII
