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.
Simulation possible

Retention
The function block does not recognize retentive data.
Example of a table function when using the EDP programming language
While in the Programming view:
Position a TB function block on a coil field in your circuit diagram.
In the Properties field window select the required function block number on the cir-
cuit diagram element tab.
Assign a numerical operand to the function block input I1 so that a numerical value
can be transferred.
Connect the coils TBxxEN, TBxxWP, TBxxRF etc. with the contact suitable for
activation.
If required, write a comment for the selected operand.
If you wish to check if a table is full or empty, you must also wire this function block as
a contact.
Position the function block on a contact field and select the same function block
number in the circuit diagram element tab that you have assigned to the coil.
If required, change the switch function of the contact from break to make contact.
If necessary, position the function block on a contact field and associate TBxxTE
(table empty) and TBxxTF (table full) with a Boolean operand suitable for eval-
uation tasks.
