NOTE
1 This area is reserved for PMC management
software. No I/O can be allocated in this area. Do
not use it in user programs.
2 This area is used to specify the precision of a
variable timer.
Don’t modifiy the value of timer and precision
except for same value when working the timer
-Don’t set the value other than the following range.
If above rules are violated, the working of the timer
is not guaranteed.
The rage other than from T9000 to T9499 are
reserved.
The value of precision
0: Default (8msec or 4msec)
1: 1msec
2: 10msec
3: 100msec
4: 1sec
5: 1min
3 This area is common memory for the multi-PMC
function. It is possible for each program to read
the same value from, and write it to, the area.
4 No extra relay is available for the dual-check safety
PMC.
