Overview
Modbus communications parameters control Modbus communications with the
transmitter.
Modbus support is implemented on the RS-485 physical layer via the RS-485 terminals.
Important
Your device automatically accepts all connection requests within the following ranges:
• Protocol: Modbus RTU (8-bit) or Modbus ASCII (7-bit) unless Modbus ASCII Support is disabled
• Parity: odd or even
• Stop bits: 1 or 2
• Baud: 1200, 2400, 4800, 9600, 19200, 38400
You do not need to configure these communications parameters on the device.
Procedure
1. Enable or disable Modbus ASCII Support as desired.
The setting of this parameter controls the range of valid Modbus addresses for your
device.

Available Modbus addresses
Disabled 1–127, excluding 111 (111 is reserved to the service port)
Enabled 1–15, 32–47, 64–79, and 96–110
2. Set Modbus Address to a unique value on the network.
3. Set Floating-Point Byte Order to match the byte order used by your Modbus host.
