B.1 Driver API Guide
In Runtime folder, on ARS2K.h :
_DLL_IMPORT_ definition is used on LoadLibrary API for ARS2K.dll.
ARS2K_EXPORTS definition is used on ARS2K.dll building.
Otherwise, that is used to compile with ARS2K.lib
BOOL Initial (BYTE Isolate_Type, BYTE DIO_NPN)
Initial machine for DIO, watchdog timer, and POE
Isolate_Type: DIO type
1: Isolated DIO;
0: Non-Isolated DIO
DIO_NPN: DI / DO type
1: PNP (Source) mode for European rule;
0: NPN (Sink) mode for Japanese rule
Return:
TRUE (1): Success;
FALSE (0): Fail (Driver not exists, or initial error (version is too old,
or machine not match))
BOOL GetDIO1Config(BYTE *Isolate_Type, BYTE *DI_NPN, BYTE *DO_
NPN, WORD *Mask)
BOOL GetDIO2Config(BYTE *Isolate_Type, BYTE *DI_NPN, BYTE *DO_
NPN, WORD *Mask)
Get DIO configuration (by variable)
Isolate_Type: DIO type
1: Isolated DIO;
0: Non-Isolated DIO
DI_NPN ([7:0]): DI type, pin setting by hexadecimal bitmask
1: PNP (Source) mode for European rule;
0: NPN (Sink) mode for Japanese rule
DO_NPN: DO type
1: PNP (Source) mode for European rule;
0: NPN (Sink) mode for Japanese rule
Mask ([15:0]): In / Out, pin setting by hexadecimal bitmask
1: Output;
0: Input
Return:
TRUE (1): Success;
