Siemens SIMATIC PCS 7 Operating Manual page 147

Procedure
1. Select one of the following options:
– If you are working with the DCS structure, select a signal below the control module.
– If you are working with the unit structure, select a signal below a position.
2. Drag&drop the signal to the function diagram.
The signal has been implemented on the channels in a previous step. See chapter Optional:
Linking hardware and software: Implementing channels (Page 136).
If the data type of the signal does not match the data type of the block connector, a
connection is not established. You can find additional information on this topic in the
"Logical" manual, keywords "Connection types for block connections" and "Allowed
connection type combinations".
3. Place generic blocks on the function diagram.
You can find more information on this topic in the "Logical" manual, keyword "Connecting
blocks".
The generic blocks OR, AND and XOR are available in the menu of the function diagram.
You have the option of using other blocks and integrating them into the menu. For example,
NOT. You can find the base objects at: "@30 > M40 > A50 > A10 > A10 > A10 > A10 > A10
> A40 Bit-wise".
4. Connect the objects on the function diagram.
Note
Connecting signals directly with the block
Always connect the hardware signal directly to the input of the placed block. Only this type
of connection configuration can be exported to PCS 7.
The following procedures are not supported: Connecting a hardware signal to a generic
block and then connecting the generic block to the block.
Result
The placed objects can be exported. See chapter Export from PAA to PCS 7 (Page 165).
