6. Function blocks
6.1 Manufacturer function blocks
Retention
The function block does not recognize retentive data.
Example of a analog value comparator function block when using the EDP pro-
gramming language
I01----A01Q1-----------------Ä Q01
I02----A01CY-----------------S Q02
Example of an AR configuration on a device display
When using the function block in the circuit diagram for the first time, use OK to auto-
matically enter the display of function blocks on the device display, as shown in the
following figure.
