Description
When the execution condition is ON, PID(190) carries out target value filtered
PID control with two degrees of freedom according to the parameters designated
by C (set value, PID constant, etc.). It takes the specified input range of
binary data from the contents of input word S and carries out the PID action
according to the parameters that are set. The result is then stored as the
manipulated variable in output word D.
The parameters are obtained when the execution condition turns from OFF to
ON, and the Error Flag will turn ON if the settings are outside of the permissible
range.
