Call in the user program
● System blocks
Only the two following FCs need to be called in the user program:
–
StartUp
Call the FC in the startup OB. The block has no parameters.
To be able to call the FC StartUp, you must first create the startup OB (OB100).
– BasicTask
Call the FC in the cyclic OB.
The DB BasicData is created automatically. The DB contains all the centrally required
data including the records of all communication partners and the connections to be
managed.
For information on the various "BasicTask" FCs, see section Note on the
"BasicTask_*" FCs (Page 133).
● Data point typicals
Depending on the communication tasks, call up all required data point typicals in the user
program.
● Optional blocks
Depending on the communication tasks, call up all required optional blocks in the user
program.
See also section The cyclic SINAUT program (Page 134) for information on calling the
blocks.
Note
Error display for library conformance
In the "Compilation" parameter group of blocks, an error can be displayed under the entry
"Library conformance" (call of single instances). This is caused by the call of global data
blocks, for example, DB BasicData.
Since the "Telecontrol ST7" library has no "know-how protection", you can ignore these error
notifications.
