Using RTSI for High-Level Integration with DAQ, IMAQ, and Motion Control Devices

This example illustrates how to use real-time system integration (RTSI) to route common signals between National Instruments data acquisition (DAQ), image acquisition (IMAQ), and motion control devices.
Master signals and slave signals are the two signal types. The master signal controls one RTSI line, and the slave signals on this RTSI line use the master signal. Each RTSI line can have only one master signal, but multiple slave signals can use the master signal. This example allows you to control the following master and slave signals for each product:

* DAQ Master Signals: AI Start, AI Scan Clock
* DAQ Slave Signals: AI Start, AI Scan Clock, AI Scan Clock Digital Gate
* IMAQ Master Signals: Acquisition in Progress, Acquisition Done, HSYNC, VSYNC, Frame Start, Frame Done
* IMAQ Slave Signals: Trigger Start of Acquisition, Trigger Each Buffer
* Motion Master Signals: Encoder, Breakpoint, Index
* Motion Slave Signal: High-Speed Capture

This example also provides a RTSI monitor that uses the DAQ counter to count the number of edges on a RTSI line, which is useful for determining how fast pulses are sent on particular RTSI lines.

There is an error in the program

Far too complex. Simple examplples are needed.
