Advanced Features

LCD BLOCK

The AI Function Block provides added capability through the addition of the following parameters:

ALARM_SEL

ALARM_SEL allows one or more of the process alarm conditions detected by the AI function block to be used in setting its OUT_D parameter.

OUT_D

OUT_D is the discrete output of the AI function block based on the detection of process alarm condition(s). This parameter may be linked to other function blocks that require a discrete input based on the detected alarm condition.

The LCD can display up to four different parameters. If a parameter from a function block is displayed, then the function block must be scheduled (downloaded) in order for it to be displayed on the LCD. If a parameter from a different device is displayed, it must be linked to a block in the Rosemount 2051 transmitter with the LCD display and it must be downloaded. It can display any input or output parameter of any block in the Rosemount 2051. The first display is pre-configured to show the value of the transducer block of the Rosemount 2051. This value can be left or changed.

1.Open the LCD block by double clicking on the LCD transducer block in Deltav Explorer.

Figure 3-4 will appear. Make sure the block is in "Automatic" mode. Then select the "Local Display" tab.
