The automation system consists of: S7315F-2 PN/DP ET200M IM153-4 SCALANCE X308-2 SCALANCE W 786 IE/PB Link PN IO ET200M IM153-1 The whole system is up and running perfect. The CPU as a Profinet controller, and the rest as Profinet devices (exept the IM153-1 ofcourse) Now, I would like to change some settings on my Scalance X308-2 via WBM. For example, I would like to enable the Fault mask for the L1 and L2 power. I noticed that is was not possible to set any values as long as the PN IO communication is ongoing. The only way I could do this was by disconnecting the CPU from the switch, so that that the PN IO communication stopped. When doing so, I was able to set the settings I wanted. When simnulating a fault at L2 (still with the CPU disconnected!), the fault lamp on the Switch goes red, and the event log gets updated... But as soon I connect back the CPU andthe PN IO com is up and running, the settings on the switch go back to what they where before... and the fault lamp on the switch turns off. So thequestion is: Is this normal? What if I decide in the future that I want to monitor som up/down links in the switch? Am I doing this the wrong way? Or is it just a constraint when integrating a switch as a PN IO device? Thanks in advance. /Said

This example use scalance x200 series. Also look at "PROFINET IO – Diagnostics Processing in the User Program" in Entry ID: 24000238 Best regards, Hristo Mihalev

I does not say anithing about setting additional eg. fault masksin the switch via WBMafter that the PN IO system is set and up and running. Regards Said
