evaluated. If the checkbox is dis-
abled instead, the function block will

Retention
Data blocks can be operated with retentive actual values.
To select the number of data blocks, go to Project view/System settings/Retention area.
The retentive actual value will require 4 bytes of memory space. If a data block is retent-
ive, the actual value will be retained when the operating mode changes from RUN to
STOP and when the power supply is switched off. If the device is started in RUN mode,
the data block will continue to work with the actual value stored in non-volatile
memory.
