6.6 Configure digital communications
The digital communications parameters control how the transmitter will communicate
using digital communications.
Your transmitter supports the following types of digital communications:
• HART/Bell 202 over the primary mA terminals
• Modbus/RS-485 over the RS-485 terminals
• Modbus RTU via the service port
The Model 1500 has only a single Modbus port.
Procedure
You have the following digital communication options:
• During the first 10 seconds after a power cycle, connect to the service port using
address 111 and the service port communication parameters.
• After the initial startup period, you can connect using Modbus with the configured
Modbus address and communication parameters.
6.6.1 Configure HART/Bell 202 communications
HART/Bell 202 communications parameters support HART communications with the
transmitter's primary mA terminals over a HART/Bell 202 network.

Overview
Basic HART parameters include the HART address, HART tags, and the operation of the
primary mA Output.
HART/Bell 202 communications parameters support HART communication with the
transmitter's primary mA terminals over a HART/Bell 202 network. The HART/Bell 202
communications parameters include:
• HART Address (Polling Address)
• mA Output Action
• Burst Parameters (optional)
• HART Variables (optional)
