Possible addresses 0 (00H) to 255 (FFH)
4)
To achieve optimum fault detection, set the inverse addresses 85 (55H) and 170 (AAH) at S1 and S2.
5)
Since the addresses of the monitoring module switches S3 and S4 are not acknowledged, this must be done by the
monitoring module contained in the last expansion unit (the most remote from the central controller). The addresses
85 (55H) or 170 (AAH) of this monitoring module must be coded at switches S1 or S2, respectively.
These addresses may no longer be occupied for I/O tasks.
