P771 Protocol Address; P772 Baud Rate; P773 Parity - Siemens Milltronics BW500 Operating Lnstructions

P771 Protocol address

Applicable only to ports programmed for Modbus RTU or Modbus ASCII (P770).
Note:
The unique identifier of the BW500 and BW500/L on the network for the selected port,
ports 1 to 3 (P771-01 to -03).
For devices connected with the Siemens 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
f
0 to 9999 ( = 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
f (01 and 02)
1
2
f (03)
3

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
BW500/L 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
f
0 none
1 even
2 odd
