I am trying to make VAT tables in This PLC PROGRAM for S7-300 , I Have a schematic with 29 pages , I need to make VAT Tables based on Sheets , for example say Sheet 7 of 29 has Digital Inputs from DI0.0 - 3.7 , also there are PIW and PQW . The original Program takes complete Input byte so there are no Use of BIT inputs, once copying the byte to the Data Block he has used the Bit from the Data Block Similarly the outputs are first copied to a Data block and later moved to the Output Address But in Schematics in PDF the inputs and outputs are in the form of - I0.0, I0.1...Q0.0 Q2.0 PIW200, PQW264 I am facing the problem that when i put the input address in the VAT table and try to edit the symbol it gets shifted and the address is gone and symbol text copies itself to the input address location therefore I created a new function block and wrote some code and edited the Symbols there Now there are two problems Some of the Input like PQW 201 and PQW 203 are not in the Program but they are in the schematics so when I make a vat table I need to add it and also need to have a symbol for it How to do that ? in the Function block I created to edit the symbol when I put PQW 264 it tells the command is not allowed , there is no PQW used in program AttachmentNew folder.zip (115 Downloads) |
