Function
Sets the Z-phase logic (positive logic/negative logic). Supports multi-processing.
Format
Ret = CntSetZLogic ( Id , ChNo , ZLogic )
Parameters
Id
[ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short
]
Specify the device ID retrieved from CntInit.
ChNo
[ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short
]
Specify the channel number for setting.
ZLogic
[ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short
]
Specify the Z-phase logic. Z-phase logic is selected from the following

CNT driver can't be called (Failed in the device I/O control). |
CNT_ERR_DLL_MODE |
10100 |
Invalid mode setting. |
CNT_ERR_SYS_BOARD_EXECUTING |
20002 |
Cannot use while by another device works. |
CNT_ERR_SYS_MODE |

Invalid mode setting. |
CNT_ERR_SYS_CH_NO |
20201 |
Channel number is out of range. |
The others: (See also: Details of Error Code)
Initial Value
Negative Logic
Remarks
Specifies the Z-phase logic of specified channel. This function becomes effective, when the counter is started.
It isn't occurred Error even though calling CntSetZlogic function when you set CNT_ZPHASE_NOT_USE by CntSetZmode function.
The internal logic level of Z-phase is hold.
All held settings are reflected to the device when the counter is stared.
For example, the counter is started following the latest settings for Z-phase
by CntSetZlogic function when you change from CNT_ZPHASE_NOT_USE to CNT_ZPHASE_NEXT_ONE
(or CNT_ZPHASE_EVERY_TIME) in the middle.
Example
Sets the Z-phase of channel 0 to negative logic.
