13.13.11 FC 2: GP_HP Basic program, cyclic section

Function
The complete processing of the NCK­PLC interface is carried out in cyclic mode. In order to minimize the
execution time of the basic program, only the control/status signals are transmitted cyclically; transfer of the
auxiliary functions and G functions only takes place when requested by the NCK.
Declaration
FUNCTION FC 2: 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 OB 1.
The following example contains the standard declarations for OB 1 and the calls for the basic program (FC2), the
transfer of the MCP signals (FC19), and the acquisition of error and operating messages (FC10).
