Eplan can now better document operational sequences

10 October 2011

Knowing the sequence of operations is always helpful, especially for the programming of control systems in machine and plant design. ‘Eplan Operational Sequence’ is now able to document the functional timeline of a machine/plant by using convenient process descriptions.

The user has a choice between a functional diagram or a GRAFCET standard. PLC programmers will benefit from the seamless documentation, controlling the interactions of actuators and sensors.

It has become increasingly difficult to clearly represent a functional timeline for machines and plant systems because of an increasing complexity and the mechatronic interaction of sub-elements. Eplan has introduced the solution with 'Eplan Operational Sequence.´ The new Eplan Platform module option includes process descriptions into the overall control systems documentation. The software offers various ways of describing these operational processes: frequently used function diagrams as well as the newest version of GRAFCET diagrams are also supported. The PLC programmer receives timely information about the necessary actuators and sensors and their operational interaction and timeline. It provides preplanning time for machine controls and accelerates the engineering processes. Changes to electrical and fluid engineering plans can then be integrated into the process descriptions automatically and documented perfectly afterwards.

The device navigator is now the central dialog for inserting Eplan functions into a function or GRAFCET diagram. It doesn't matter if the function has already been placed into the schematic, or if it will be created as a new device. Only the values for time/step scales, as well as the process sequence, need to be entered into the diagram after placement. The necessary forms are included and values can even be inserted as macros. The only remaining manual step is be the process sequence with the aid of graphic elements such as polylines. An automatic translation into foreign languages is available right from the start, as well as other quality increasing functionalities in the process sequences.

The ´Eplan Operational Sequence´ module option will be available with the release of Eplan Electric P8 2.1 and is part of Eplan Fluid, the second Platform system, included with the delivery scope of version 2.1.
