We are interfacing an IFM make CR 1081 device using CAN open protocol with NI 9853 cRIO device.
We have used the example for CAN engine as described in the following URL
http://zone.ni.com/devzone/cda/epd/p/id/6093
We ran the "PDOExample.vi" and have created an Index with following information from the CR1081 HMI device.
Node ID:
25
COBID:
266
We found a strange behavior of the CAN bus reading junk 1D array values even without sending any data frame from the CR1081 HMI device
To cross verify we also used the USB CAN card and connected the same to the CAN bus, however, the USB device does not read any data on
COB ID/Arb.ID =266
(Verification done using MAX>>USBCANDevice>>BusMonitor)
We would like to know why the PDOExample code in the RT cRIO is returning us junk 1D arrray data, though no frames are present on the bus?
Is this a know behavious? If yes Is there any work around?
Thanks
