- it is recommended to read these registers simultaneously – (1,2) and (7,8), (D3h,D4h) in 2-registers frames, and
registers (9h,Ah,Bh,Ch) in 4-registers frames. If single registers are read, data errors are possible because of
changes of read value between successive registers readings. Zeroing of
total flow counter
is possible by preset of
0000h to any one of it's registers (09h ÷ 0Ch). Controlling of
batcher counter
is possible by writing appropriate
value (
0
- zeroing,
1
- start/continue,
2
- pause) into one of the
batcher counter
registers (0Dh ÷ 0Fh). Zeroing of
number of batches counter
is possible by preset of 0000h to any one of it's registers (D3h ÷ D4h).
2
- these registers are active only if device is equipped with active current or voltage output
3 - after writing to register no 20h the device responds witch an “old” address in the message.
4
- after writing to register no 22h the device responds with the new baud rate.
5
- 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.
