Hi Roman,

I need to write the register of my rs485 device according to MODBUS, the MODBUS frame should be "0C 10 00 1B 00 02 04 7F FF FF FF A0 E8", there are 2 registers should be operated, how can I control the register number in the attributes list? what I wrote in the attributes list is "R:27:r:ti:ti", but the register number is always "00 01".

Thanks a lot!

Learn, learn and learn better than work, work and work.
