Hello Hero_pro, the PIDConL block doesn't support a function to inhibit the increase of MV. The PIDConL block has the Inputs "IntHoldPos" and "IntHoldNeg" with the Parameter "1" the Integrator cannot run in positive/negativ direction (see the manual Advanced Process Library in the section PIDConL I/Os). This method is used against the integrator windup for cascade control within the distributed control system (see the templates of the PCS 7 Advanced Process Library). Another solution is to implement this function in a CFC. In the attachment you can find an example CFC to inhibit the increase of MV. The blocks have following function:
