Manufacturers of machinery are increasingly using application programming of safety controls in order to implement safety functions. As a result, the functional safety of the control systems also depends on the application programs, which have undergone extensive development and testing. A key requirement set out in the relevant standards (e.g. DIN EN ISO 13849-1) is that these programs must be developed according to a structured work process and measures aimed at avoiding faults must be taken. As part of a project funded by the German Social Accident Insurance (FF-FP 0319 "Standard-compliant development and documentation of safety-related application software in machine and plant construction"), which ran from 2011 to 2013, the Bonn-Rhein-Sieg University of Applied Sciences established a practically applicable development method. The IFA matrix method has already been presented at events for German social accident insurance institutions and industrial companies, where it was discussed and found to be useful. As part of project IFA5133, an IFA Report on this topic was created.
The IFA matrix method is used for the specification, validation and testing of safety-related application programs. This method requires multiple tables to be completed for different development phases. The SOFTEMA software tool was developed on the basis of project IFA5137 "SOFTEMA - A tool for safety-related programming on machines" for automated application of the tables used in the IFA matrix method. The purpose of SOFTEMA is to assist both machine manufacturers during the development of these programs and external bodies during the inspection and testing of such programs. The functions of SOFTEMA are intended to assist in reducing and detecting input errors and to generate documentation for programming and tests. The efficient and error-free modification of specifications and application software is a key aspect of SOFTEMA. It is intended to raise awareness of the IFA matrix method, and in doing so, to assist the standard-compliant development of safety-related application software in the machine and plant construction sector.
