Model 2400S Transmitters with Analog Outputs
Optional Configuration
8.11 Configuring digital communications
The digital communications parameters control how the transmitter will communicate using digital
communications. The following digital communications parameters can be configured:
• The Modbus address (used for service port or Modbus connection types)
• Modbus ASCII support
• The HART address (used only for HART connection types)
• Loop current mode
• Infrared port write-protect
• Floating-point byte order
• Additional communications response delay
• Digital fault indicator
• Burst mode
• PV, SV, TV, and QV assignments
8.11.1 Configuring addresses and related parameters
Two addresses can be used to identify or connect to the transmitter: the Modbus address and the
HART address. You may configure either or both, or leave them at default values.
Note that the service port always responds to either of the following addresses:
• The service port address (111)
• The configured Modbus address (default=1)
Configuring the Modbus address
The set of valid Modbus addresses depends on whether or not support for Modbus ASCII is enabled
or disabled (see following section). Valid Modbus addresses are as follows:
• Modbus ASCII enabled: 1–15, 32–47, 64–79, 96–110
• Modbus ASCII disabled: 0–127
