Hello!
I am using a SMD-7615 Ethernet Stepper Drive and try to read digital IO (X1 to X8).
Using invoke node "Read Digital Line" returns nonsense. X1 and X2 seem to be always correct, the rest however changes oddly. E.g. changing a High/Low level on X5 also affects X6 and X7 (but there is no clear correlation).
However the Inputs X1-X8 displayed in "Drive Status Monitor" of "NI Stepper COnfiguration Utility" show the correct state.
We have the same behavior on 4 SMD-7615, so a faulty device seems unlikely.
How do I properly read the state of a digital input from LabVIEW?
Attached you find a test-VI and a screenshot of the Configuration Tool.
