Hello everyone.
I’m trying to make a datalogger in a S7-1200 (1214C DC/DC/RLY to be precise) to upload read data from a network analyzer Socomec A-30, I’m connecting this device with the PLC via Modbus TCP (I’ll leave the link to the modbus registers at the end of this post), but I’m having some trouble reading data from the server (Diris A-30).
Via the cmd I made sure the devices are well connected, so there aren’t errors regarding wiring or IP address assignment as far as I’m aware.
I tried out first reading a couple of registers with a two MB_client with different variables at the CONNECT terminal it was just fine, but when I kept adding more MB clients some MB blocks stopped reading and the STATUS variable showed the following error code 80A3, I looked up on the Tia Portal Help and I couldn’t find a clear description of the error, as far as I know it is trying to stablish an already existing connection?
The thing is after randomly recoding and downloading the program all the sudden the blocks started working. After adding one more, this last one had showed on STATUS “80C5” and “80C4”. After that I tried using only one CONNECT variable for all the MB_Clients I had but of course timing everything properly. Like last time it worked for a pair of blocks but once I kept adding more the 80A3 error showed up again, and after recoding and stop the plc several times I couldn’t make it work again.
Could somebody please help me out with this issue? What does the 80A3 error mean in this case considering all the context mentioned before?
I’ll upload the program if you want to get a closer look, you may check out mainly:
