1 - it is recommended to read these registers simultaneously – in 2-registers frames. If single registers are read, data
errors are possible because of changes of read value between successive registers readings.
2 - after writing to register no 20h the device responds witch an “old” address in the message.
3
- after writing to register no 22h the device responds with the new baud rate.
4 - the value of the “mbAccE” parameter is also connected to write to this register, so it is possible to block a writes,
but impossible to unblock writes via RS-485 interface, The unblocking of the writes is possible from menu level only.
