Type 0: Process Instruction Structure for PI Sheets

For the system to correctly process universal process instructions in the PI sheet, you must define the characteristics in a certain sequence.

In the following sections, the characteristics are grouped into characteristic blocks according to their purpose. You can combine them into process instructions in the following sequence:

First, you define phase sequences.
Second, you define data requests.
Third, you define the message creation. You can define as many process message blocks as you like.
Fourth, you define any of the remaining characteristic blocks. Each characteristic block can be defined any number of times. You can define these characteristic blocks in any sequence.
