PID8AT n S1
a) Usage
when the condition of execution is on, PID auto tuning operation executes and calculates P,I,D constant
‘n’ is registration No.at parameter( 0 ~ 7)
S1 is execution status and P,I,D constant registration area
b) Example program
When the input condition M0 turns on, PID operation executes at no.2 parameter.
PID execution status stores D0000 and the output value of control result stores D0001 and P,I,D constant sequentially
store D002(P),D003(I),D004(D)
Done : normal execution signal
D0000
