I am having an issue accessing S7-300 counters. I can access the Counter at offset 0 juts fine. I can read and write to the counter. The Ignition address for Counter 0 is [S7_300]C0
But I cannot access Counter 2. Neither read nor write. I used the address [S7_300]C2
What I did discover is that after changing the address to [S7_300]C4 and creating another tag with address [S7_300]C6, suddenly I could read Counter 2, but the Ignition address is specified at [S7_300]C4.
The challenge though is that I cannot write to the Counter, I can only assume this has to do with incorrect address, offsets and conversion to BCD.
Has anyone experience this issue?
