8.7 CFC-Chart Settings

Overview of Functions

8.7.1
If you want to process a parameter in a CFC chart and this parameter is to be changeable during runtime using
DIGSI or HMI, you can use the function blocks CFC chart of Boolean parameters, the CFC chart of integer
parameters and the CFC chart of floating-point parameters. Instantiate the appropriate function block
depending on the parameter value needed (logical, integer, or floating point). In this way, the current value of
the parameter can then be used in the CFC chart at runtime.

Function Description

8.7.2
You can find the CFC-chart parameters Chrt sett.Bool , Chart setting Int , and Chrt sett.real
in the DIGSI library in the User-defined functions folder. Drag and drop the desired function block into a func-
tion group or a function. Set the appropriate parameter value of the function block in DIGSI using the param-
eter editor or via HMI under the Settings menu item. You can then use the parameter as an input signal in CFC
charts.

The user-defined function groups and the user-defined functions can be used to group the CFC-chart
parameters. You can rename for the function block and change the parameter value in the DIGSI Informa-
tion routing matrix to suit your specific application.
