Conversion and development of new typecircuits for Siemens PLC

Abstract: Automationscenter & Bråvalla Elteknik AB offers complete turnkey solutions to the market where the customer can operate and monitor their production from operator panels. This total solution lacks today type circuits in Siemens PLC controls for operating, control and monitoring of process-driven objects. The report begins with a description of the company. Then the purpose of the examination work is described, and the specifications as the basic for our work. After that it presents how the work began with a feasibility study of software programs for Mitsubishi PLCs. The report then continues with how the programs for Siemens PLC system works and which components that were used. The result was a documentation of the conversion of four type circuits, and the development of two brand new type circuits. These type circuits have also an operator interface for each type circuits. Software code is available to all type circuits in the report as an appendix. The programming for each piece is commented to make it easier to understand. Even the operator images to each type circuit are attached as an appendix.
