Emerson 2200S User Manual

To configure and make the administrative connection using the Communicator or ProLink II:

1. Make a startup connection to the transmitter using default HART parameters as listed below:

•

HART address = 0

•

Baud rate = 1200

•

Parity = Odd

•

Stop bits = 1

Note: For information on using ProLink II, see Appendix D. For information on using the 
Communicator, see Appendix E.

2. Set the HART address as required. Valid HART addresses are 0–63. The HART address must 

be unique on the network. You do not need to change the default address unless the transmitter 
will be on a multidrop network. To set the HART address:

•

Using the Communicator, select 

.

•

Using ProLink II, click 

.

Note: If you set the HART address to a non-zero value, Loop Current Mode is automatically disabled 
and the mA output will not report process data. See Section 6.3.2 for information on enabling Loop 
Current Mode.

3. If desired, set the software tag (also called the HART tag). Devices on the network may use 

either the HART address or the software tag to communicate with the transmitter. To set the 
software tag:

•

Using the Communicator, select 

.

•

Using ProLink II, click 

.

4. Disconnect the startup connection and reconnect using the new parameters.

If the Micro Motion adapter-barrier is installed, the mA signal received by the host is scaled from 
4–20 mA. If the adapter-barrier is not installed, the mA signal received by the host is scaled from 
12–20 mA. For the configuration and maintenance tasks listed below, you must know which scale 
applies:

•

Configuring the fault value (if Fault Action is set to Downscale)

•

Performing a loop test on the mA output

•

Performing an mA output trim or scaled AO trim

•

Viewing output levels

For these tasks, Micro Motion has included scale conversion routines in the Communicator device 
description and in ProLink II. These tools will perform scale conversion based on the mA 
measurement point (see Section 3.4.1). If you are not using the Communicator or ProLink II, you may 
need to perform scale conversion manually (see Section 3.4.2).

The mA measurement point is used by ProLink II and the Communicator to interpret the mA data, that 
is, whether to use a 12–20 mA scale or a 4–20 mA scale. Both ProLink II and the Communicator 
prompt you to specify this information whenever it is needed.
