这里是如何使用没有缓冲区的输送机跟踪的示例。 即项目触发仅在NOI = 0之后。 该过程包括一个全局标志，表示在传送带上检测到物品。 在实际应用中，应监视相机的数字信号，而不是全局标志。

以下是传送带的配置文件 

System.NumberAxes = 5

common shared SCARA as group Axnm=a1 Axnm=a2 Axnm=a3 Axnm=a4 Model=4 of xyzr
common shared LIN_CONV		as moving frame of xyzr 

Program

	A5.AxisName = CONV

        Load ETHERCAT.LIB
        Load EC_USER.LIB
        Load EC_CDHD.LIB
        Load ECX_DIO8.LIB
        Load EC_AI8ME.LIB
        Load CPX_FB38.LIB
        Load EC_HCNC.LIB
        Load EK1100.LIB
        Load TP_PARAM.LIB
        Load TP_EC.LIB
        Load TP.LIB

	sys.DoubleFormat = 1
	sys.NoMotion = 1

        Sys.Name = "SCARA_CT"
	Print "System is ready - " Sys.Name
	
End Program



以下是传送带的设置文件
