P771 Protocol address
The unique identifier of the SF 500 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
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
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 SF 500 and all
connected devices.
e.g many modems default to N-8-1 which is No parity, 8 data bits, and 1 stop bit.
Values
Note:
Applicable only to ports programmed for Modbus RTU or Modbus ASCII
(Parameter 770).
