Sequential Function Chart (SFC) is used for describing procedures with alternative or parallel sequencers. SCL-blocks form the basis for sharing program code between S7-1200, S7-300, S7-400 and WinACĬonsiderable time savings compared to programming in LAD/FBD/STL Ideal for user-defined function blocks for libraries SCL blocks can be used in other STEP 7 languages The values of all tags are displayed clearly online Loops and multi-line comments can be expanded and collapsedįast access to tag parts (bit, byte, word.) with 'slicing'“ S7-SCL Editor offers the following functionalitiesĬomplete areas of program code can be activated/deactivated with just one click Programming efficiency is enhanced using new, high-performance SCL The SCL code is simpler, shorter and clearer to produce and handle. Particularly suitable for the high-speed programming of complexĪlgorithms and arithmetic functions and for tasks in data processing. Level and reusability level requirements according to PLC open. (Structured Text) defined in the standard IEC 61131-3 and fulfills base This permits simple navigation between the errors and has an indicator for faulty networks.Ĭontrol Language (SCL) corresponds to the textual high-level language ST Troubleshooting is made easier and quicker thanks to several tools – a syntax window lists all errors in the current block. The embedding of the various editors in a common working environment ensures that all data is available to the user on a consistent basis and an overview of the project data is assured at all times. Programming editors and the latest Windows technologies adapted to tasks and processing provide the basis for the intuitive STEP 7 (TIA Portal) operating concept. It is also straightforward to have different programming languages in a single block. STEP 7 (TIA Portal) therefore enables efficient creation of user programs. Statement list (STL) and step sequence programming (GRAPH, SFC) are additionally available for the controller series S7-1500, S7-300, S7-400, WinAC and the S7-1500 Software Controller.įunctions such as drag & drop, project-wide cross-reference list and Autocomplete provide users with intuitive tools for all tasks. Structured text (SCL), ladder logic (LAD) and function block diagram (FBD) languages are available for all controllers SIMATIC STEP 7 (TIA Portal) provides powerful programming editors for programming SIMATIC S7 controllers
