Using PID basic functions
The technology object CONT_C provides a continual PID-controller for automatic and
manual mode. It corresponds to the instance data block of the instruction CONT_C. You can
configure a pulse controller using the PULSEGEN instruction.
The proportional, integral (INT) and differential components (DIF) are switched parallel to
each other and can be turned on and off individually. With this, P-, I, PI-, PD- and PID-
controller can be set.

All parameters and tags of the technology object are retentive and can only be changed
during download to the device if you completely download CONT_C.
