Good morning all,
I'm working with a S7 1200, connected with modbus to the computer. In the computer I'm using the latest AdvancedHMI (just downloaded), and MS Studio 2019 (comunity).
There are some questions, first and the most headbreaking for me. PLC is working as a server, it can only works with holding registers. I need to do some setups from the final HMI, by changing bits of a register, in order to make it works.
I'd been trying what i found in the forum, about addressing, 40001.X, or B:40001.X, and etc. But nothing works. If I use a button with a register, its value will turn 1, thats ok, but in the moment i try to address a bit of the register, nothing happens, no error, no change.
The second question is, when i try runtime with analog values, through different registers, it works perfectly, but every x seconds, it changes to a message "Address must be 4-11 digits, 0" for some seconds, and next changes back to normal, in a continuous loop.
Thank you in advance.
Regards.
