Emerson 9739 Manuel D’Utilisation

The service port clips on the user interface of the transmitter are directly connected to the RS-485
terminals (26 and 27). If you wire the transmitter for RS-485 digital communications, you cannot use
the service port clips for communication with the transmitter.

HART/Bell 202 communications parameters support HART communication with the
transmitter's primary mA terminals over a HART/Bell 202 network.

The HART/Bell 202 communications parameters include:

•

HART Address

 (Polling Address)

•

Loop Current Mode

 (ProLink II) or mA Output Action (ProLink III)

•

Burst Parameters

 (optional)

•

HART Variables

 (optional)

1.

Set HART Address to a unique value on your network.

Valid address values are between 0 and 15. The default address (0) is typically used
unless you are in a multidrop environment.

Devices using HART protocol to communicate with the transmitter may use either HART
Address

 or HART Tag (Software Tag) to identify the transmitter. Configure either or both, as

required by your other HART devices.

2.

Ensure Loop Current Mode (mA Output Action) is configured appropriately.

Enabled

The primary mA output reports process data as configured.

Disabled

The primary mA output is fixed at 4 mA and does not report process
data.
