Type 0: Definition of Automatic Value Assignment

Use

You can use this function to determine the point of time (date and time) at which a process instruction was processed in the browser-based PI sheet or in the process manufacturing cockpit . In a process instruction, you can automatically assign a value to the date and time once for each message category block.

Features

You can automatically assign the date or time as values to the following standard characteristics:

PPPI_EVENT_DATE: date of the event
PPPI_EVENT_TIME: time of the event

The system determines the date and time when you maintain the process instruction in the PI sheet.

Activities

When defining automatic value assignment, you specify the following information in the process instruction:

A variable that refers to the characteristic whose value is to be assigned automatically if you want to use the date and time in another process instruction of the same process order

Caution Caution

Note that you may use global variables in PI sheets only.

End of the caution.

The message characteristic whose value is to be assigned automatically
The characteristic PPPI_OUTPUT_CHARACTERISTIC that you can use to display the date and time in the PI sheet

Note Note

You can also mark the date and time as input values. The system then proposes the current date and time in the possible entries. Unlike automatic value assignment, however, you can still change the value.

End of the note.

To enter this information, you assign the following characteristics to the process instruction in the order specified below:

Characteristic	Meaning	Value
Variable definition for the characteristic whose value is to be assigned automatically < PPPI_VARIABLE In PI sheets only: < PPPI_GLOBAL_VARIABLE	Variable Global variable	New variable name New variable name
PPPI_AUTOMATIC_VALUE	Message characteristic whose value is to be assigned automatically	PPPI_EVENT_DATE PPPI_EVENT_TIME
PPPI_OUTPUT_CHARACTERISTIC	Characteristic to be output	PPPI_EVENT_DATE PPPI_EVENT_TIME
