FC2 : GP_HP - basic program, cyclic section

Function
The NC/PLC interface is processed by the basic program in cyclic mode (OB1). To keep the
runtime to a minimum, only the control and status signals are cyclically transferred. The transfer
of auxiliary and G-functions is only processed upon request from the NC.
Furthermore, the data for handwheel selection, modes, and other operating signals are
transferred from the operator panel (HMI) to the NC/PLC interface so that the modes support
the selection from the MCP or HMI as required.
The transfer of HMI signals to the NC/PLC interface can be deactivated by setting the value
of the parameter "MMCToIF" to "FALSE" in FB1 (DB7).
Handwheel selection signals
Requirement: FB1, parameter "HWheelMMC == "TRUE"
The handwheel selection signals from the HMI are decoded and activated in the respective
machine or geometry axis of the respective handwheel.
