Hi, For pointer addressing see this link as a start: How can you construct an ANY pointer in S7-SCL using the AT function?
I hope I could help! |

Hi, all variables in TIA Portal have "global" scope... it's just a matter of addressing them. You can easily access any variable of any db (glob or instance) from any FB or FC there is... Be careful about using ANY ptr. I for example, did not manage to make it point to single to single bit... Because of that, I'd suggest you to use "Indirect Addressing": link. It is very useful particularly for implementing loops (indexing etc...) Janko |
