Hello,

I am using a 1517 TF CPU and CU310-2 PN.

In the electric schematics a sensor (DI) is connected directly to DI/DO 08 on the CU310-2 PN.

I want to use passive homing in the technology object (I checked the "use homing mark via digital input").

My questions is how to know at which adress is the signal from sensor at DI/DO 08 located, so I can put the adress in the input filed "Digital input homing mark/cam".

Thank you for your answer in advance.

Regards.

Thank you for you answer. I had been using free telegram. Now I have set it to telegram 390. I connected it to X121.7 on the CU.

When the sensor is ON, I do not get any change in the status word of the telegram. The sensor is wired correctly. Do I have to turn on a certian parameter?

Regards.

Thank you I got it to work.

Downlaoded the LPD library from:

I created with a PLC with dataype of Tel 390 (image in attachment). The adress was set the same as start adress in the telegram configuration.

I can clearly see the desired I/O in the structure.

Regards.
