CntGetZLogic

Function

Gets Z phase logic. (Positive logic/Negative logic)

Format

Ret = CntGetZLogic ( Id , ChNo , ZLogic )

Parameters

Id [ C: short ] [ Python: ctypes.c_short ]
Specifies the device ID retrieved from CntInit.

ChNo [ C: short ] [ Python: ctypes.c_short ]
Specifies the channel number which you want to get.

ZLogic [ C: short * ] [ Python: ctypes.POINTER(ctypes.c_short) ]
Specifies the address of the variable that stores Z phase logic. As for Z phase logic, either of the following defined values is returned.

Definition	Value	Description
CNT_ZLOGIC_POSITIVE	0	Positive Logic
CNT_ZLOGIC_NEGATIVE	1	Negative Logic

Return Value

Ret [ C: long ] [ Python: ctypes.c_long ]
