SFC program shows Questions marks (?) when the program is running
Dear experts, I take contact with you because I have an issue when we try to run a program on a CPU PM554-ETh. Originally the logic was programed in differents PDUs using FBs, but now we need to add two new PDUs, one programed in SFC (Called SELEC_BOMBAS_SFC) and the anotherone in FB (called TRANSICIONES). The problem come us when we try to simulate or run the new proyect. The new PDUs are shown in grey on the PDUs tree on the left. Also, the Global Variables appear as Questions marks (?). Please take a look on the attachments. Excuse me if this query result to much basic for you, but it is our first experience with ABB PLCs. Thank you very much in advance.

Hi Gaston
at first glance, it would seem that the two new POUs you have added are not called in the MAIN block, often PLC_PRG is called but you can change them by name ... it seems a simple and obvious thing, but sometimes we all forget too of the simplest things ....
Don't forget to recompile the project and when you download it to the CPU, and create boot project
Hope this help you
