Abstract
Abstract A control and monitoring arrangement for drives of moving parts of a machine for the manufacture of structural parts in two or more steps is equipped with controls for the drives. The drives may be pressure fluid operated and they are electrically and/or electronically controlled through switching and control modules. The switching module actuates the drive and the control module cooperated therewith for controlling the actuated drive. A releasable coupling detachably connects the control module to the switching module for ready replacement of the control modules in each control. A monitoring module is connected to, and cooperates with, the control module.
