Profibus slave (DP-DP Coupler) connection issue with AB7800

@anongfpquean
Hi,

Can you try the scan with no serial cables plugged in and see if the Anybus detects itself? Make sure you have good ethernet connection first–

Thank you,
Kyle

Ticket notes:

  • Cannot detect slave device in scans. Seems like a possible cable issue with Profibus cable. We have tried 2 different AB7800s with 2 different laptops.

Hello Kyle,

No – same result.

With profibus cable unplugged, HMS unit restarted and “driver” connection is good – Anybus cannot find even itself. Is it OK?

Thank you for your help,

I set one up here to test, and if it’s disconnected from Profibus cable, the Net scan still detects the Anybus as Profibus Master. See if there is a difference in the configs?

Hello Kyle,

I tried your setup.

(DPDP)

Anybus cannot detect even himself in this scenario.

What’s your firmware revision of your Anybus AB7800?

Thank you,
