We use a combination of MCIN/MCOUT and AIN/AOUT blocks in an AB Gateway. It
is redundant, but for individual alarms, CIN blocks may be connected to MCIN
blocks.

About the way to adress points... are you using MCIN/MCOUT, PACKIN/PACKOUT ?
and if it's so, how do you treat individual alarming in DCS for each signal
?
We have some similar AB-DCS comms (old ABStation, and INT30-KF2), but we are
usung CIN/COUT because of the alarm/acknowledge capacities...
Operator disliked those blocks with 8 alarms because the ack is for all 8,
not each one separatelly (BOOLALM).
So we cannot optimize loads and/or add more points.
Do you think using MCIN/MCOUT in integrators and MCIN+CIN in CP is a
feasible approach ? (more pear-to-pear, though)
