System- and communication configuring D7-SYS - SIMADYN D
Edition 03.2001
2.1.3.2 The second step: Parameterizing and interconnecting function
blocks
After the function blocks have been selected, these are interconnected
and parameterized using the CFC editor. The task, in which the individual
function blocks are computed, must also be defined.
By double clicking on the function block header or under the menu
selection
Edit > Object characteristics
, the following data can be
configured deviating from the pre-settings:
Data
Description
General
The name and a comment text which is displayed in the
function block header can be configured. Under "special
object properties" you can execute the steps which are
necessary to prepare a block for operator control and
monitoring using WinCC.
Run-time
properties
Here, the execution sequence of a function block, defined
under function block insert, can be changed within a task.
The selected function block can be "searched for", "cut-out"
in the execution sequence, and "inserted" in another
position.
I/O
The following I/O data can be entered here for all
parameters:
•
value and comment for input and output parameters
•
visibility in the CFC chart for parameters which are not
interconnected
•
set or inhibit parameter ID for test
•
scaling value for parameters, REAL data type
•
texts for the various units

Configuring function blocks
Additional information
Refer to the Manual "TEP7 Optionspakete für D7-SYS, Section CFC".
Function blocks which are consecutively executed within a task can be
combined to form a run-time group. In addition to structuring the task, this
allows task execution to be individually enabled/disabled.
NOTE
If a run-time group, is disabled via a function block input which is
connected to it, then all of the function blocks contained in it are no
longer computed.
