Using CM below EM/EMT in function diagram

Introduction
The CM created below EM/EMT can be used in the function diagram. CM can be created newly
or can be created from the existing CMT.
Use cases
CM created and not defined as basic requirement is displayed on the function diagram as
separate block and can be used as normal CM in the function diagram.
CM defined as basic requirement is not displayed on the function diagram.
The Control module assignments below EM/EMT are not displayed on the function diagram.

Editing the logic on function diagrams

Requirements
● A control module has been edited on a function diagram.
See also chapter Editing control modules on the function diagram (Page 146).
Use of blocks
You can use the following generic blocks:
● AND
● OR
● XOR
● NOT
You have the option of using other blocks. To do this, the blocks must be defined as a standard
function in PCS 7. Note the following:
● The name of the standard function in PCS 7 corresponds to the block label in PAA.
● The name of the block connections in PCS 7 corresponds to the label of the block
connections in PAA.
