PROFINET data alaways zero

When I use the PLC which is S7-300 (6ES7315-2EH14-0A0B), I connect robot by profinet. The data of major version or joint position… all data is zero. I’m sure the robot is power on.


Did u try the other way?
I mean did u try to set a Bit from PLC and read it out at the UR?

and are u sure that the Setup of the UR is correct?

I try to set standard digital output, but robot have no action. The standard digital output is low level. I’m sure the UR is correct.



How did u setup ur UR?

Make a small test programm.

Set ur digital output Q352.0 = True and then read that one at the UR:


and then do:

and check ur DI 104.0

also check ur settings at the UR…

I had some issues before with the adress:

I setup UR as the same way. But the input boolean register and output boolean register is False.
