Communic
a
tion
P771 protocol address
Note:
Applicable only to ports programmed for Modbus RTU or Modbus ASCII
(Parameter 770).
The unique identifier of the BW500 on the network for the selected port, ports 1 to 3
(P771-01 to –03).
For devices connected with the Milltronics protocol this parameter is ignored.
For devices connected with a serial Modbus protocol this parameter is a number from
1-247. It is up to the network administrator to ensure that all devices on the network
have unique addresses.
Do not use the value “0” for Modbus communications as this is the broadcast address
and is inappropriate for a slave device.
Values
0 to 9999 ( f = 1)
P772 Baud Rate
The communication rate with the master device for the selected port, ports 1 to 3
(P772-01 to –03).
The baud rate chosen should reflect the speed of the connected hardware and
protocol used.
Values
1 4800 baud
2 9600 baud
3 19,200 baud
f -03
4 38,400 baud
P773 Parity
The serial port parity for the selected port, ports 1 to 3 (P773-01 to –03).
Ensure that the communications parameters are identical between the BW500 and all
connected devices.
For example many modems default to N-8-1 which is No parity, 8 data bits, and 1
stop bit.
Values
0
none
f
1 even
2 odd
