F_CXNaviSwitch
The function F_CXNaviSwitch converts the value of the CX1100 navigation switch into an enum value of type E_CX1100_NaviSwitch.
FUNCTION F_CXNaviSwitch: E_CX1100_NaviSwitch
VAR_INPUT
iCX1100_IN : USINT
END_VAR
E_CX1100_NaviSwitch: Value of the CX1100 input 'IN'
Enum E_CX1100_NaviSwitch
TYPE E_CX1100_NaviSwitch : (
e_CX1100_NaviSwitch_IDLE := 0,
e_CX1100_NaviSwitch_MIDDLE := 16,
(* clockwise in 45 degree steps *)
e_CX1100_NaviSwitch_TOP := 1,
e_CX1100_NaviSwitch_TOPRIGHT := 9,

e_CX1100_NaviSwitch_MIDDLE_BOTTOMLEFT := 22,
e_CX1100_NaviSwitch_MIDDLE_LEFT := 20,
e_CX1100_NaviSwitch_MIDDLE_TOPLEFT := 21
END_VAR
Values other than those defined in enum (e.g. 11) are displayed as "*** INVALID: value ***" in online mode (e.g. "*** INVALID: 11 ***"). The function F_CXNaviSwitch then returns the invalid value (e.g. 11).
