Declaration
FUNCTION FC2: VOID
// no parameters
Call example
As far as the time is concerned, the basic program must be executed before the user program.
It is, therefore, called first in OB1.
The following example contains the standard declarations for OB1 and the calls for the basic
program (FC2), the transfer of the MCP signals (FC19), and the acquisition of error and
operating messages (FC10).
