ON-LINE AND OFF-LINE OPERATION

5.0 ON-LINE AND OFF-LINE OPERATION

On-line operation is any configuration or monitoring activity which involves direct communication with a transmitter. When the controller function block is disabled, the local pushbuttons may be used to configure range and damping. When the controller is enabled, the local pushbuttons may be used to display PROCESS VARIABLE (PV), SETPOINT (SP) and VALVE (V); transfer control mode from AUTO

(A) to MANUAL (M); and change or store SET POINT and VALVE settings.

The configuration may be edited remotely using an MXC, a personal computer (PC) running XTC Configuration Software, or another HART Primary or Secondary Master. The MXC can also be used to monitor a transmitter’s variables and to look at a transmitter’s status.

Off-line operation is any configuration activity that occurs without direct communication with a transmitter. This includes using the MXC to create or edit a configuration and then to store that configuration in an MXC archive. It also includes using a personal computer and XTC Configuration Software to create or edit, and then store, a configuration.

5.1 ON-LINE OPERATION

The first part of this section contains the steps to configure and monitor a Model 344 from an MXC. The latter part of this section describes configuring the transmitter using the local pushbuttons.

5.1.1 Using the MXC for Configuration

Each transmitter is shipped with default data stored in its memory. Some of this data controls communi- cation and transmitter operation and cannot be altered by the user. Other data determines how the transmitter responds to changes in temperature with a change in current or digital output and is alterable by the user. Using the MXC in the on-line mode, configurations can be uploaded from the transmitter, edited, and saved to archive memory or downloaded to the Model 344. The following sections describe configuration in more detail.

The following sections are in a two column format. Step-by-step procedures are in the right column. The left column contains relevant MXC screens.
