11.9 INTERFACE FUNCTIONS FOR NG35
This group of functions allows the interfacing to the hardware resource of NG35 systems.
Hardware NG35
NG_DI - DIGITAL INPUTS
This function allows to read the digital input of the expansion cards of NG35: NG-IO and NG-PP.
The expansion cards are identified with a progressive number starting from 0. The first card near the NG35 has the
index 0.
Syntax
Uint NG_DI(Char Card)
Parameters
Card Index of the expansion card (from 0 to 7)
Return value:
Uint Value of 16 BITS of the input, if Bit is 1 the input is ACTIVE

input = ng_di(0) ‘ read the digital inputs from the first card
input = ng_di(2) ‘ read the digital inputs from the second card
NG_DO – DIGITAL OUTPUTS
This function allows to updates the digital output of the expansion cards of NG35: NGIO and NGPP.
The expansion cards are identified with a progressive number starting from 0. The first card near the NG35 has the
index 0.
Syntax
NG_DO(Char Card, Uint Out)
Parameters
Card Index of the expansion card (from 0 to 7)
