Service port connections
HART/Bell 202 connections
Modbus/RS-485 8-bit connections (Modbus RTU)
Modbus/RS-485 7-bit connections (Modbus ASCII)
Service port connections are specialized Modbus/RS-485 connections that use
standard connection parameters and a standard address that are already defined in
ProLink III. Service port connections are typically used by field service personnel for
specific maintenance and diagnostic functions. Use a service port connection only
when another connection type does not provide the functionality you need.
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.
