Hello,
I have managed to connect to the Opta WiFi using Modbus TCP over Ethernet. I'm reading just 3 registers cyclically, using one read request per register. The time to read these three registers is nearly 50ms. This seems quite slow. For comparison, reading three registers in the same way from a Schneider Modicon M221 takes only 2-3ms. Is there any way to improve the performance?
Secondly, it appears that writing registers using masking (FC22) doesn't work. Is this not supported?
Thanks,
Kareem
