A.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.
A.2.1 Connection types supported by ProLink III
Different connection types are available for connecting from ProLink III to the transmitter.
Choose the connection type appropriate to your network and the tasks you intend to
perform.
The transmitter supports the following ProLink III connection types:
• Service port connections
• HART/Bell 202 connections
• Modbus/RS-485 8-bit connections (Modbus RTU)
• Modbus/RS-485 7-bit connections (Modbus ASCII)
When selecting a connection type, consider the following:
• 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.
• 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.
• Service port connections can be made only when the transmitter’s RS-485 terminals
are in service port mode. If they are not, you must switch them to service port mode
by power-cycling the transmitter and connecting within the first 10 seconds.
