5.5.2 Sequence
The following flow chart provides an overview of the sequence of the individual control signals and the
subsequent switching conditions between the beginning and end of a tightening process of a tightening
controller. Use of the individual PLC signals depends on the individual case of application, e.g. Setting of
CHxyPrg0...7.
