Parameter set
 Description Note
Parameter set 
Function block release by
EN is necessary
If this checkbox is enabled, the
state of function block input EN will
be evaluated. If the checkbox is dis-
abled instead, the function block
will be enabled and function block
input EN will not do anything.
This parameter ensures that
when existing programs are
copied, the functionality of the
function blocks that are carried
over will be retained. The para-
meter will be automatically set to
0 or 1 depending on the function
block.
No edge evaluation of T bit

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 retentive, 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.
