Further details on the function can be read in the TwinCAT documentation. The function can be used in a program as
follows: (The declaration and linking are as given in the example above)
CASE F_CXNaviSwitch(Taster) OF
e_CX1100_NaviSwitch_IDLE :; (* do nothing *)
e_CX1100_NaviSwitch_MIDDLE :call_select; (* select item *)
e_CX1100_NaviSwitch_TOP :call_prev_item; (* previous menue item *)

e_CX1100_NaviSwitch_BOTTOM :call_next_item; (* next menue item *)
e_CX1100_NaviSwitch_LEFT :call_dec_value; (* decrease value *)
END_CASE;
Further evaluation of the switch inputs is then done later in the program.
