reading of holding register limited to 125 bytes #67

Reading quantity for holding register (and others) are limited. Not sure why this is limited, but I would like to read quite some more. Can I change this? Are there any limitations?

p.s. this would be over tcp/ip

Ah, just found my answer: modbus message size may not exceed 255 bytes....

I also encountered this problem, is there any good solution? @pdorrestijn
