System use only
1) S_TIME
The scan time in PID operation means the interval of sampling the present value (PV). In
general, the PID operation shows best performance when the S_TIME is synchronized
with external enable input. (The input condition of PIDCAL instruction)
The range of S_TIME is 0.1 ~ 10 seconds. However, when input S_TIME data into PLC
device, it is scaled up 10 times for more precise setting. Therefore, the actual range of
input data is 1 ~ 100.
