Hello, the are many step5 plc family. What cpu do you have? Anyway in all plc you have OB1 that is cyclic program execution block, instruction in OB1 are ciclically executed by cpu (you don't have to do noting except write instruction inside OB1). then there are interrupt OB, time controlled OB... To get an idea please refer to pag147 of this manual (specific for s5-135-155 family). If you have more specific question please ask. Regards AttachmentS5 - List of operations.pdf (158 Downloads) |
