216 Function Manual, 03/2017, A5E35300227-AC
Technology object TCONT_CP
The technology object TCONT_CP provides a continual temperature controller with pulse
generator. It corresponds to the instance data block of the instruction TCONT_CP. The
operation is based on the PID control algorithm of the sampling controller. Both manual and
automatic mode are possible.
The instruction TCONT_CP calculates the proportional, integral and derivative parameters
for your controlled system during pretuning. "Fine tuning" can be used to tune the
parameters further. You can also enter the PID parameters manually.
