FAULT DEPENDENT GROUP associates a set of adapters such that if one
adapter in the group faults, all the other adapters in the group fault, going
to their fail-safe mode of operation. The scanner must be in Program mode
to issue this command. You can specify as many as 8 fault groups.

Parameter: Description:
0220 fault dependent group block There are 4 configurable bits for each starting group entry.
An adapter must be in the current scan list to be assigned to a
faultĆdependent group. If you specify an adapter that is not in
the scan list, the scanner writes an illegal configuration error
(16H) to the confirmation status byte. See Figure 6.8
and Figure 6.9.
