6. Function blocks
6.1 Manufacturer function blocks
You can assign the following operands to the function block outputs that are numeric
outputs:
Assigning operands Outputs
Constant x
Markers: MB, MD, MW x
Analog inputs IA x
Analog output QA x
Numeric output from another QV FB x
You can assign the following operands to the function block outputs that are bit outputs:
Assigning operands Bit outputs
Constant 0, constant 1 x
M – Markers x
SN - Output bit via NET (send) x
N - Network marker bit x
nN - NET station n marker x
LE - Output backlight x
Q - Bit output from another FB x
Parameter set
Configuration/time range Description Note
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 disabled instead, the function
block will be enabled and function
block input EN will not do any-
thing. This parameter ensures that
when existing programs are
copied, the functionality of the
function blocks that are car-
ried over will be retained. The
parameter will be auto-
matically set to 0 or 1 depend-
ing on the function block.
Parameter display
+ Call enabled Function block parameters and con-
stants can be edited on the device.

Retention
The function block does not recognize retentive data.
Example for BIN operating mode
For simulation purposes in easySoft 7, function block input I1 can be connected to a
marker double word instead of to a binary source. The value of this marker double word
can be entered in hexadecimal or decimal format. It will always be interpreted as binary
at function block input I1.
