2.12.11 FC 2: GP_HP Basic program, cyclic section
Description of Functions
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).
