You can use this function to define input fields in the browser-based PI sheet or Process Manufacturing Cockpit in which you want someone to enter values.
In the PI sheet and cockpit, you can use input fields for the following:
To record specific actual values from the production environment
In the PI sheet, you can also use input fields for the following additional functions:
To execute signatures that are to complete a process step in the PI sheet
To execute signatures that complete the entire PI sheet
See also Completing Browser-Based PI Sheets
Note
You can also define signatures that complete process instructions in cockpits but here Complete only means that process messages are created automatically.
You can use a process message to report the values the process operator has entered.
See also Type 0: Definition of Message Creation .
In addition, you can define the following functions for the value to be entered:
A default value
An input validation
If you want to report the value entered, the characteristic that is marked as the input value must be contained in the message category.
The number of input fields to be created depends on the type of data request:
One input field is created for a simple data request.
A table column is created for a repeated data request.
Note
If you do not enter a data request type, the system sets "simple data request" by default.
When defining an input value, you specify the following information in the process instruction:
A text that is displayed before the corresponding input field or above the corresponding table column in the PI sheet or cockpit
The message characteristic whose value is made available as the default value for the input value in the PI sheet or cockpit
See also Type 0: Definition of Default Values
A variable that refers to the input characteristic if you want to use the characteristic in another process instruction of the same process order
The message characteristic whose value you want to enter
If required, an input validation that is used to check the input value in the PI sheet or cockpit
See also: Type 0: Definition of Input Validations
Here you define one of the following functions:
A check formula for numerical values
A check function for all values
To enter this information, you assign the following characteristics to the process instruction in the order specified below:
Characteristic |
Meaning |
Value |
PPPI_INPUT_REQUEST |
Input request |
Any short text |
< PPPI_DEFAULT_VALUE or < PPPI_DEFAULT_STRING or < PPPI_DEFAULT_VARIABLE or < <Any message characteristic> |
Default value < Numerical value < Alphanumerical value < Variable < Characteristic value |
Default value: < Any numerical value < Any alphanumerical value < Existing variable name < According to characteristic definition See also: Type 0: Definition of Default Values |
< PPPI_VARIABLE In PI sheets only: <PPPI_GLOBAL_VARIABLE (See also: Process Instructions for Process Manufacturing Cockpits ) |
Variable definition for value entered: < Variable <Global variable |
Variable definition: < New variable name <New variable name |
PPPI_REQUESTED_VALUE |
Message characteristic whose value is assigned manually |
Characteristics of the assigned message category |
< PPPI_VALIDATION_FORMULA or < PPPI_VALIDATION_FUNCTION > <Parameters for check function> |
Check formula Check function |
Input validation: Boolean formula (see Syntax of Check Formulas ) Name of the function module See also: Type 0: Definition of Input Validations |
PPPI_TEXT_FOR_INVALID_INPUT |
Long text for invalid entries |
Any long text |
PPPI_ACCEPT_INVALID_INPUT |
Accepting invalid entries |
- Accept always - Accept never - Accept with signature only |
In PI sheets only: PPPI_SIGNATURE_AUTHORIZATION |
Authorization for signature |
Any value for the Activity field in the authorization object C_CRPI_BER |
In PI sheets only: PPPI_SIGNATURE_STRATEGY |
Signature strategy |
Signature strategy |
Note
A value can be assigned automatically to the characteristics for the date (PPPI_EVENT_DATE) and time (PPPI_EVENT_TIME) in the PI sheet. If you define these characteristics as input values, the system proposes the current values as possible entries in the PI sheet.
