Efficient drive engineering by the use of profile based IEC 61131 function blocks

Motor control offers a huge variety of area or custom specific solutions. These possibilities can be found in the process control system (PCS) also. However uncounted variants of device parameterization, different cyclic process image definitions and watchdog checks lead to a high complexity, which can be reduced by the consequent usage of profiles. Also today there are some profiles in use, but they are built from the field bus communication view point. This article introduces an approach which presents both, drive control and device diagnosis from the process control systems point of view, in order to reduce engineering cost. The suitability of the approach has been verified in a prototypical implementation.
