The number of points indicated in Table10.8 starting from the set counter number
is used as interrupt counters.
In order to use an interrupt counter, an "interruption permitted" status must be
established by E1 instruction at the main routine program.
Table10.8 Number of interrupt counter points of each CPU module

High Performance model QCPU,
Process CPU, Redundant CPU
128 points, starting from the set counter number, are
used as interrupt counters.
When the first interrupt counter No. is set to C300,
C300 to 427 are used as interrupt counters.
256 points, starting from the set counter number, are used as
interrupt counters.
When the first interrupt counter No. is set to C300, C300 to 555
are used as interrupt counters.
