1
- these registers are active only if device is equipped with current or voltage output
2
- after writing to register no 20h the device responds with 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 “
mbAc
” 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.
5
-
the pairs of „
X
-
Y
” coordinates may be defined for any free point. The pair is “free” (it means that particular point is
not defined) if „
X
” coordinate of this point is equal 8000h. After writing both X and Y coordinate the point is defined
and used in calculation of result. The coordinates of any point can be changed at any time.
