SmcWGetLatchOutPulse

Function

Retrieves output pulses in which the latch is done by the LTC signal input is acquired.

Format

Ret = SmcWGetLatchOutPulse( Id , AxisNo , OutPulse )

Parameters

Id [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
SSpecify the Deice ID retrieved by SmcWInit function.

AxisNo [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify axis number.

OutPulse [ VB.NET: Integer ] [ C, C++: long * ] [ C#: out int ] [ Python: ctypes.POINTER(ctypes.c_long) ]
Specify the address of the variable that stores the feedback output pulse number.
The pulse number is displayed with absolute coordinate.

Return Value

Ret [ VB.NET: Integer ] [ C, C++: long ] [ C#: int ] [ Python: ctypes.c_long ]

Remarks

It is necessary to set IN4 to LTC with SmcWSetCtrlTypeIn.
It is necessary to select the counter to which the latch is done with SmcWSetCounterMode.

This function can be executed even if the axis is in operation.

Example

Axis number 1 acquires the number of feedback output pulses in which the latch is done.

VB.NET
Dim Ret As Integer
Dim OutPulse As Integer
Ret = SmcWGetLatchOutPulse( Id , 1, OutPulse )

C, C++
long Ret;
long OutPulse;
Ret = SmcWGetLatchOutPulse( Id , 1, &OutPulse );

C#
int Ret;
int OutPulse;
Ret = Smc.WGetLatchOutPulse( Id , 1, out OutPulse );

Python
Ret = ctypes.c_long()
OutPulse = ctypes.c_long()
Ret.value = csmc.SmcWGetLatchOutPulse( Id , 1, ctypes.byref(OutPulse) )
