Service port connections
HART/Bell 202 connections
HART/RS-485 connections
Modbus/RS-485 7-bit connections (Modbus ASCII)
Modbus/RS-485 8-bit connections (Modbus RTU)
Service port connections use standard connection parameters that are already
defined in ProLink III, and therefore you do not have to configure them.
HART/Bell 202 connections use standard HART connection parameters that are
already defined in ProLink III. The only parameter you must configure is the
transmitter address.
Some connection types require opening the wiring compartment or the power
supply compartment. These connection types should be used only for temporary
connections, and may require extra safety precautions.
Modbus connections, including service port connections, are typically faster than
HART connections.
When you are using a HART connection, ProLink III will not allow you to open more
than one window at a time. This is done to manage network traffic and optimize
speed.
You cannot make concurrent connections if the connections use the same
terminals. You can make concurrent connections if the connections use different
terminals.
