How do I use two FP-1601 controllers at the same time in a labview application? I need more than 9 modules, so I am forced to use two 1601 controllers. When I open MAX, I am able to see the two controllers (each with separate 192.168.1.x addresses) in the Remote Systems, but I cannot view or change the values of the second controller in Data Neighborhood.
Also, when I attempt to read/write the second controller in Labview, I get an error 32812 stating "The specified tag name was not found".
You should be able to use two 1601 controllers in the same fashion as you would use one. Simply use a FP Read.vi or FP Write.vi with an I/O Point assigned. Of course, you will need to use a separate FP Read or Write VI for each module you want to sample from.
