Type 0: Definition of Calculations

Use

You can use this function to perform calculations in the browser-based PI sheet or process manufacturing cockpit. You can, for example, calculate the total quantity of a material consumed in all phases. You can then use a process message to report the calculated value. You can define a variable to pass on the calculated values to a function module, for example.

Activities

When defining calculations, you specify the following information in the process instruction:

A text to be displayed before the calculated value in the PI sheet or cockpit
If required, a variable that refers to the characteristic to be calculated
The message characteristic whose value you want to calculate
The calculation formula to be used to calculate the value

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

Characteristic	Meaning	Allowed Values
PPPI_INPUT_REQUEST	Text displayed before the formula result	Any short text
< PPPI_VARIABLE In PI sheets only: < PPPI_GLOBAL_VARIABLE	Variable definition for value calculated: < Variable < Global variable	New variable name see: Definition of Variables
PPPI_CALCULATED_VALUE	Message characteristic to be calculated	Message characteristic
PPPI_CALCULATION_FORMULA	Calculation formula	Arithmetic expression; see: Syntax

In the case of text characteristics (such as PPPI_INPUT_REQUEST), you can insert the value of another characteristic into this text using a text symbol; see Text Symbols in Characteristic Texts.
