Hello, Mark:

My device B needs the frist byte high for one word. and my gateway device has the same order. Why I am not able to contact them? How Beijer reads the CRC?
My crc word order is CRC Low and CRC High.

hello, Mark:

Finally, it works with our device on serial and ethernet. The problem is holding registers address between 40000 and 465535; however, modbus reading function is 0x3. I think I confuse it. So I put address starting number 3; however between 30000 and 365535 is for input register.

Thanks
