I recently bought a Publisher for Modbus IP publish-ip-unlimited licence.
Now when trying to feed a third party TCP Modbus Master, I get in trouble.
The master needs to read multiple registers with length 120. That fails. I tried reading multiple registers with length 16, that worked. 32 didn't.
Sadly there is no documentation about a lenght restriction IMHO.
For my project it is really important to be able read 120 registers at once!!! If not implemented in the module, would it be possible getting that included soon?
Anybody who can give advice?
