Why Am I Getting a "No Explicit Path Found Between the Two Channels" Error? Primary Software: LabVIEW Development Systems>>Full Development SystemPrimary Software Version: 7.1 Primary Software Fixed Version: N/A Secondary Software: Driver Software>>NI-SWITCH Hardware: SCXI>>Modules>>SCXI-1128, SCXI>>Modules>>SCXI-1129, SCXI>>Modules>>SCXI-1127
Problem: I initially wrote a program to connect two channels in the SCXI module in matrix mode. During the testing phase, the connectivity of the route created was checked and the path was indeed created. However when I write another program to disconnect the channels I get an error that no explicit path exists between these two channels. Why? Solution: Initially when the program to connect the channels was made to run, it created the connections required and the link existed even when the program was closed. When another program is created to disconnect the channel, the switch driver resets the module so that any prior connections that were made will be cleared. Hence, the channel created will be lost and will not exist at that point of time. Therefore, any further attempt to clear the non existent channel will fail. In order to maintain the link and have the capability to close it later, the instrument handle can not be closed. Related Links: Attachments:
