Operator Prompt (P_Prompt)
Add-On Instruction

Global Object
Operator Prompt (P_Prompt)
The P_Prompt (Operator Prompt) Add-On Instruction is a universal
mechanism for operator interaction that can be used within a control scheme.
The instruction presents an operator with configurable message or data fields and
accepts operator response data and confirmation.
Rockwell Automation Publication SYSLIB-RM046C-EN-P - January 2016 7
Operator Prompt (P_Prompt)
Guidelines
The configuration data for a set of prompts are stored in an array of user-defined
types (UDTs). Each configured prompt instance is a member of the Prompts
array. By referencing different members of the prompt configuration array, the
same P_Prompt instruction can be used to access multiple user-prompt
combinations, one at a time.
A single prompt can include the following:
• An 82-character message
• Up to four numeric value displays
• Up to four numeric value entries
• Choose one choice among 2…4 options
• Up to four text responses
The RespData tag at the bottom of the P_Prompt
function block lets you define where to store
operator responses. This tag stores any operator
response as a string in the application.
8 Rockwell Automation Publication SYSLIB-RM046C-EN-P - January 2016
Operator Prompt (P_Prompt)
Functional Description
Use a prompt to request input from an operator. The input can be any of
the following:
• Acknowledging the prompt
• Viewing and confirming data
• Making a selection
• Entering numeric data
• Entering text data
Do not use a prompt in place of an alarm or an alert:
• An alarm, per ANSI/ISA-18.2-2009, is used to notify an operator of an
abnormal situation that requires a response
• An alert is used to notify an operator of an abnormal situation that does
not require a response
• A prompt requires a response, but does not advise of an abnormal situation

Operator Response Not Required Normal values and status Alert

Operator Prompt (P_Prompt)
Prompt Demonstrations
There are two separate demonstrations that show how you can use the prompt
functionality:
• Standalone prompt
• Sequencer prompt faceplates (see page 13
Standalone Prompt
In its simplest form, the P_Prompt instruction provides operator interaction and
can be invoked from a number of users. This example shows how to program and
configure the P_Prompt instruction to solicit an operator comment.
The example below shows the logic for the Prompt instruction to continually
reset to provide for more operator entries.
)
The Inp_Req is set to '1' to buffer the prompt configuration and trigger the
prompt. This causes the prompt button on the FactoryTalk View display
to be active.
10 Rockwell Automation Publication SYSLIB-RM046C-EN-P - January 2016
Operator Prompt (P_Prompt)
Click the prompt button to access the prompt faceplate shown below to let the
operator enter a comment in the text box.
The Boolean output (Out_Cfm) remains low (0) until the operator clicks the
Acknowledge button (green check mark circled below) on the prompt faceplate
in the FactoryTalk View client.
Clicking this button on the faceplate causes the boolean output (Out_Cfm) to
transition to a one (1).
The function block logic then inverts the Boolean value and feeds it back
to the Inp_Req input. When this input goes to zero (0), it causes the output
(Out_Cfm) to be reset to zero (0), which reasserts the input again and retriggers
the instruction.
Rockwell Automation Publication SYSLIB-RM046C-EN-P - January 2016 11
Operator Prompt (P_Prompt)
The standalone prompt example is achieved by setting the following values in the
configuration array element zero [0].
The desired configuration can be moved into the configuration array from other
Logix entities or populated from a P_Prompt configuration display. The
P_Prompt configuration display can be called from the global object file
(RA-UI) Prompt Objects.ggfx.
For additional information, see the following:
• Standalone programming basics, page 20
• Tag configuration options, page 27

Sequencer Prompt Faceplates
This section illustrates basic prompt functionality by using the Sequencer Object
(P_Seq) instruction and faceplates.
This demonstration uses the Sequencer’s Run Time Detail faceplate as an
example only. You can use the prompt with other tasks and processing tools.
1. After placing the Sequencer’s display element into your project, click the
object.
Our example is Seq Prompt Scaling.
The Operator tab for the P_Seq instruction appears with buttons,
including the Prompt (circled below).
These same buttons also are available on the Run Time Detail faceplate
that visually arranges the progress of the steps and prompts.

2. Click the magnifying glass button to access the Run Time Detail
faceplate.
The following faceplates show different types of prompts that can be
configured for a sequence. Our example shows the prompts in close
succession merely as a teaching tool and likely is not the case for
your sequence.
See the Sequencer Object Reference Manual, publication
PROCES-RM006
, for how to configure a sequence by using
the Sequencer Object.

3. Click the Start command button.
Column turns green to show
the current step in progress.
Prompt icon appears to notify
the operator that some type of
interaction is necessary.

4. Click the Prompt button when it appears during a step.
You also can click the Prompt button when it is active on the
Sequencer’s Run Time Detail faceplate or the Operator tab.
A Prompt window appears to tell the operator what action is necessary.
5. Click to acknowledge the prompt.
The sequence continues until the next configured prompt occurs.
