Items Shared by the Timer and Counter
Timer and counter partitioning
Timers and counters share the same area. The partitioning of the area can be changed
to obtain the number of timers or counters needed.
Partition the area by setting system register 5. If the initial number of the counter is
specified, those prior to that point will be timers, and those subsequent to that point will
be counters.
If the same value is set for system register 5 and 6, timers are non
−
hold types, and
counters are hold types. Normally, the same value should be set for both system
registers.

hold type partitioning
The contents of timer contacts, counter contacts, set value areas and elapsed value
areas can be held when the power is turned off or the mode switched from RUN to
PROG., and operation later resumed based on those contents.
In the case of the FP0 C10/C14/C16/C32, and FP
−
e without clock/calendar function,
the areas which hold their contents when the power is turned off are fixed as shown
below. System register settings 6 to 8 as well as 14 become invalid.

word number, the contents of timer/counter contacts and set value/elapsed value
areas before that point will be non

hold types, and subsequent the contents of
timer/counter contacts and set value/elapsed value areas will be hold types.
