■ PID8AT (Auto-tuning by parameter)
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).
