ProLink III messages
As you use ProLink III with a Micro Motion transmitter, you will see a number of messages and notes. This
manual does not document all of these messages and notes.
Important
The user is responsible for responding to messages and notes and complying with all safety messages.
B.2 Connect with ProLink III
A connection from ProLink III to your transmitter allows you to read process data, configure the transmitter,
and perform maintenance and troubleshooting tasks.
B.2.1 Connection types supported by ProLink III
Depending on the channels that are licensed on your transmitter, you may have several connection types
available to connect from ProLink III to the transmitter. Choose the connection type appropriate to your
network and the tasks you intend to perform.
Table B-1: Connection types supported by ProLink III
Connection type
Service port
HART/Bell 202
HART/RS-485
Modbus/RS-485 8-bit (Modbus RTU)
Modbus/RTU 7-bit (Modbus ASCII)
When selecting a connection type, consider the following:
• Some connections require opening the wiring compartment. These connection types should be used only
for temporary connections, and may require extra safety precautions.
• Service port connections use standard connection parameters and a standard address already defined in
ProLink III.
• Channel E auto-detects incoming connection requests, and automatically responds to both HART and
Modbus.
• HART/Bell 202 connections use standard HART connection parameters that are already defined in ProLink
III.
• RS-485 connections and service port connections are typically faster than HART/Bell 202 connections.
