PID8(PIDCalculation)
a) Usage
•
when the condition of execution is on, PID operation executes.(only rising edge condition)
•
‘n’ is registration No.at parameter( 0 ~ 7)
b) Example program
•
When the input condition F0093(1second clock) is rising edge(off
⎢
on) PID operation executes at no.2 parameter.
•
PID execution status registrate D0000 and the output value of control result registrate D0001
