8.2.1.1 Restrictions with the Creation of a Function Diagram
For the creation of a function diagram several exceptions must be paid attention to:
•
Blocks and data types
In the type instance and in the application blocks of the AU library, only blocks and data
types supported by CP-8000/CP-802
x
can be used.
•
Signals from the signal list
From the signal list only signal types supported by CP-8000/CP-802 x can be used in the
type instance (for instance the message with TI 38 – “protection event” is not allowed).
The check is performed via the data type of the signal. Also the system data point from the
signal list can not be used in the type instance.
•
System data points
These are available as global variables in the global variable object “System info” in the
resource. These global variables can be used in the FUD.
•
Type identifications
Since the type identifications supported by CP-8000/CP-802 x are restricted, a check is
performed during the creation of the FUD. Messages with not supported type identifica-
tions can not be used in the FUD.
•
Non-volatile states
If messages or inputs/outputs of blocks are set to “retain” in the FUD, then a correspond-
ing warning is output upon the code generation.
•
CASDU
All the information that is produced in the application program of CP-8000/CP-802 x has
the same CASDU in the message address. Thereby it is necessary that for parameter-
settable messages that originate in the application program, the same CASDU is assigned
in the CAEx
plus link (see 9.1.3.1.1 , Application Program ). With “wrong” setting in the
“OPM II” the code generaration aborts with a corresponding error information.
For input messages in the FUD an arbitrary message address can be assigned.
•
Status bit „Class 1“
This is not supported by the FUD (priority management of the communication function).
•
Status bit „R“ (redundancy)
This can not be set by the target device. Using the redundancy bit a warning will be output
upon code generation.
•
Additional attributes
These are not supported by CP-8000/CP-802 x . Upon code generation these attributes are
not taken account of, and neither a warning nor an error will be output.
•
Periodical datapoints
CP-8000/CP-802 x does not support periodical links (1703 links with use in the FUD, no
evaluation of the parameter
use_caex_plus
). With periodical use, the variables must be
entered directly in the FUD (system variables with predefined names). These system vari-
ables can be found in the
SICAM TOOLBOX II Online Help in the datenpoint description of
the I/O Master Module firmware (internal key 92128 up to 92255).

trol Function”
