Network and Modbus Setup
The
Network and Modbus Setup
menu is where the wireless device’s
Network ID
is set and Modbus
®
se-
rial communications settings are programmed.
Network ID
The network ID determines
primary
and
secondary
wireless pairs. The primary and secondary
units must share the same unique network ID in order to communicate.
Modbus Timeout
The Modbus timeout sets the length of time the wireless devices will wait for a reply from the
other Modbus device before returning an error. This should be 1 to 2 seconds at 9600 bps on the
primary device.
Modbus Baud Rate
The baud rate of the wireless devices must match the baud rate of the Modbus network in order
to prevent collisions on the bus. The baud rate may be set between 1,200 and 57,600 bps.
Data Format
The data format of the wireless devices must match the data format of the Modbus network. Set
the data format to either
8E1
(8-bit, even parody, 1 stop bit),
8O1
(8-bit, odd parody, 1 stop bit), or
8N2
(8-bit, no parody, 2 stop bits).
