Function Manual, 03/2017, A5E35300227-AC
213
The technology object CONT_S provides a step controller for actuators with integrating
behavior and is used to control technical temperature processes with binary output value
output signals. The technology object corresponds to the instance data block of the CONT_S
instruction. The operating principle is based on the PI control algorithm of the sampling
controller. The step controller operates without a position feedback signal. Both manual and
automatic mode are possible.

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_S.
