(For the High Performance model QCPU, Process CPU, Redundant CPU, Universal
model QCPU)
(Bit devices capacity) + (Word devices capacity) + (Timer, retentive timer and
counter capacity)

For bit devices, 16 points are calculated as 1 word.
(Bit device capacity) =
(b) For timer (T) retentive timer (ST), and Counter (C):
For the timer, retentive timer, and counter, 16 points are calculated as 18 words.
(Timer, retentive, counter capacity) =
(c) For word devices:
