Advanced function block faceplates

The faceplate library includes pop-up faceplate displays for the Advanced function blocks. These displays are located in the FaceplateFB subfolder under the Pictures folder in the DeltaV Operate configure mode. (In the DeltaV directory, they are in the DeltaV\DvData\Graphics-iFix\Pic\FaceplateFB subdirectory.) 

The faceplates are listed in the following table:

AVTR Faceplate

The faceplate display for the AVTR function block, AVTR_fp, is opened in runtime from a button on the AVTR dynamos on the primary (or other) display. The faceplate display consists of a tabbed control, a "close picture" button, a pushpin button, an "open module faceplate" button, and the function block path similar to what is shown in the example below. The pushpin button appears when multiple faceplate capability has been enabled in UserSettings.grf. When multiple monitor capability has been enabled, a display selector appears to the right of the pushpin.

CEM Faceplate

The faceplate display for the CEM function block, CEM_fp, is opened in runtime from a button on the CEM dynamo on the primary (or other) display. The faceplate display consists of a tabbed control, a "close picture" button, a pushpin button, an "open module faceplate" button, and the function block path. The pushpin button appears when multiple faceplate capability has been enabled in UserSettings.grf. When multiple monitor capability has been enabled, a display selector appears to the right of the pushpin.

There are two tabs: General and Overrides. The faceplate display is opened in Run mode in the context of a single Effect as configured when the CEM dynamo was pasted on the picture in Configure mode.

General Tab (CEM Faceplate)

The following items are contained on the General tab of the CEM function block faceplate:

• A text value field for the effect description, DESC_EFFECTx.

• To the left of the effect description is the value of EFFECTx (1 or 0, where 1=normal and 0=tripped). The background color is that of the Status global color table based on EFFECTx.ST.

• Below the effect description is the named state of STATEx. When STATEx is "Ready to Reset," a Reset pushbutton is visible to the right of the text. A click on the Reset button resets RESETx. When STATEx is "Trip Initiated - Delayed," the value of DELAY_TIMER appears to the right of the text.

• Below the STATEx text field are 16 rows, one for each potential associated Cause for this Effect. Visibility for a row is enabled when that Cause is associated with this Effect per the particular bit in MATRIX[x] and that Cause is not being masked per CAUSE_MASK. A visible row will always show the text description for CAUSEy (DESC_CAUSEy). When CAUSEy is inactive per bit y in ACTIVE_CAUSESx, the color of the text is the inactive color (default is gray) of a global color table. When bit y is active, the text color is the active color (default is bright red).

• To the left of the text field is a value field for CAUSEy (where 1=normal and 0=trip demand). The background color is that of the Status global color table based on CAUSEy.ST. When the value of FIRST_OUTx is non-zero, a red "first out" arrow points from left to right to each Cause that was active when the trip was initiated (in practice there is normally one visible arrow). The arrows remain visible until the block clears FIRST_OUTx.

Overrides Tab (CEM Faceplate)

The following items are contained on the Overrides tab of the CEM function block faceplate:

• A text value field for the effect description, DESC_EFFECT.

• To the left of the effect description is the value of EFFECTx (1 or 0). The background color is that of the Status global color table based on EFFECTx.ST.

• Below the Effect description is a text label (Current Overrides) and the text value for OVERRIDESx, always visible.

• Remove Force button - When OVERRIDESx is "Forced to Trip" or "Forced to Normal," there is a button visible labeled "Remove Force." Clicking this button sets FORCE_EFFECTx to "Do not Force."

• Force Trip button and Force Normal button - When OVERRIDESx is "None" or "All Associated Causes Masked," and FORCE_PERMIT is True or a force permit is not required (FORCE_OPTS.PermitNotReq=True), there are two buttons visible labeled "Force Trip" and "Force Normal." Clicking these buttons sets FORCE_EFFECTx to "Force Trip" or "Force Normal" per the button pushed.

• Forces are not permitted at this time - This text string is visible if FORCE_PERMIT is False and a force permit is required (FORCE_OPTS.PermitNotReq=False).

• Allow Forces button - Visible when FORCE_PERMIT is False and the force permit control should be visible (FORCE_OPTS.ForcePermitVisibleInHMI=True). Clicking this button sets FORCE_PERMIT to True.

• Disallow Forces button - Visible when FORCE_PERMIT is True and the force permit control should be visible (FORCE_OPTS.ForcePermitVisibleInHMI=True). Clicking the button sets FORCE_PERMIT to False.

• Red Stop Sign -Visible next to the Disallow Forces button when LATENT_TRIP is True and the force permit control should be visible (FORCE_OPTS.ForcePermitVisibleInHMI=True). A visible stop sign indicates that removing the force permit will result in a trip, that is, there is an Effect being forced to Normal that has one or more active Causes.

STD Faceplate

The faceplate display for the STD function block, STD_fp, is opened in runtime from a button on the STD dynamo on the primary (or other) display. The faceplate display consists of the main display area, a "close picture" button, a pushpin button, an "open module faceplate" button, and the function block path. The pushpin button appears when multiple faceplate capability has been enabled in UserSettings.grf. When multiple monitor capability has been enabled, a display selector appears to the right of the pushpin.

The main display area has a text label (Current State) and the STATE parameter, always visible, showing the current state of the block. There are two columns of conditionally visible text strings.

The left column header has the label "Transition Condition," and the right column has the label "Transition State," always visible. In the left column, DESC_INx parameters are visible, based on the value of VALID_TRANS. This results in text descriptions being visible for those inputs currently being evaluated by the block.

The right column has a text string visible to the right of each visible string in the left column, indicating the state to which the block will transition if that input becomes True. The text string is one of the opsel states of STATE based on MATRIX and VALID_TRANS.

SEQ Faceplate

The faceplate display for the SEQ function block, SEQ_fp, is opened in runtime from a button on the SEQ dynamo on the primary (or other) display. The faceplate display consists of the main display area , a "close picture" button, a pushpin button, and "open module faceplate" button, and the function block path. The pushpin button appears when multiple faceplate capability has been enabled in UserSettings.grf. When multiple monitor capability has been enabled, a display selector appears to the right of the pushpin.

The main display area has a text label (Current State) and the STATE parameter, always visible, showing the current state of the block.

Below the text label "Outputs" there is a column of text descriptions of DESC_OUTx parameters whose color is based on the value of OUT_Dx and a global color table. The descriptions of outputs whose value is True in the current state are shown more prominently than those whose value is False.
