Basic Timer
Specifications
The following table shows the basic specifications of the timers.
Note (1) TIM PVs are refreshed at execution for all times and also every 100 ms
for T0000 to T0015.
(2) TIMH(015)/TIMHX(551) PVs are refreshed at execution for all times and
also every 10 ms for T0000 to T0015.
