Hi everyone,
I am using step 7 Simatic manager V5.5 for S7-300 (cpu319-3PN/DP). I have created a udt in DB1 which contains DINT and I want to access it from OB1. I could not find the right access name for DINT like DB1.DBD1 (which I know is for DWORD) I have read in a few forums that you can access bit, byte, word and dword only when accessing from DB. Please let me know if it is true.
Also, second question is if I change my DINT to DWORD would I be able to perform mathematical equations like add subtract etc. on Dword data type.
Thank you!
