I have four 6axis force transducers hooked up to a PCI-6071e. Each force transducer outputs 6 differential channels.
To create the virtual channel for the first force transducer, I write
ftTask.AIChannels.CreateVoltageChannel("Dev1/ai0:5", "",
AITerminalConfiguration.Differential, -0.1, 0.1, AIVoltageUnits.Volts);
But the second force tranducer is hooked up to ai6:7 and ai16:19, ie, the physical channels are non-contiguous because:
(from the help file)
A 64-channel
E Series device has physical channels
ranging from
Dev1/ai0 to
Dev1/ai63. You can configure channels in banks of every
other eight beginning with 0 through 7 as the positive channel of a differential
pair (0-7, 16-23, 32-39, and 48-55). If
N is this channel, channel
N + 8 is the negative input of the pair.
Does this mean that I can't create a virtual channel with the differential inputs in this physical configuration? If I can, what is the syntax?
Thanks,
Gerry
