Hello, I am a trainer and I would like to present the programming of S7-1200 (TIA v19) PLCs as closely as possible to the IEC 61131-3 standard. I'm using this document [STEP 7 Standards compliance according to IEC 61131-3 (3rd Edition)] dated April 2015. I don't know if there is a more recent one? In this document, page 23, table 25. AttachmentIEC_61131_compliance_en_US.pdf (68 Downloads) |

An other example The standard contains the mentions of CONCAT_DATE_TOD and CONCAT_DATE_LTOD. In the help : T_COMBINE: Combine times (S7-1200, S7-1500) « Note Use of T_COMBINE in SCL programs When you drag the instruction "T_COMBINE" from the "Instructions" task card to the SCL programming window, the internal instruction CONCAT_DATE_TOD or CONCAT_DATE_LTOD is displayed there. » Standard and TIA STEP 7 use different names. |

Be sure and enable IEC check for every created block in that case. It's a property for OBs/FCs/FBs (or attribute depending on your thoughts). Default is unchecked.
