Siemens - How to diagnose the ports of my Scalance XR324-12M switch (Profinet)?

[benxi]

Hello,

I would like to be able to read useful information in S7 v5.5 about the status of the different ports on my Scalance switch; such as which port is connected, which one is not connected,...

I am actually able to know if my switch is connected or not to my PLC (and generate an alarm), but I can't get more diagnostic information. I use the SFC51 block in order to read datas in my switch. SFC51 sends me back datas in a word "eastat". I have found in Simatic manager help :
BIT 0 =1 => "I/O Status" Could somebody explain me what does it mean?
BIT 1=1 => module failure
BIT 2=1 => module is present. Here I guess it is a communication information (PLC S7300 <->Switch)
BIT3 = 1 =>unavailable module. I guess than if bit 2 = 1 then bit 3 =0. Am I right?
BIT4=1=> disabled module
and so on...
===> no very useful information as regards the management of my switch

I know there is a possibility using SNMP, but I need an OPC server + OPC client for this. I don't have it for my project.

Does somebody have some experience about it?

Thanks in advance

Benoît

I have experience with other Scalance model for fiber ring who includes web-server for parametering and monitoring.
For each port was parameter, as 'must be in use'.
If not, it is in faulty state and activates alarm contact who was connect to plc's input.
With browser can see port animation, are they in use or not or faulty.
In Scalance was 4 RJ-ports, 2 fiber pairs for fiber ring, reduntant 24V= supply and not ok. (=alarm) contact.

Thank you for your reply

...But I was seeking for a "coding" solution, over the network.
The most easy way is definitely to use SNMProtocol but I need to set up a Simatic OPC server, and I don't know how the OPC client of my HMI software will react (as it is a very specific software; guy who sells the software said me than the OPC feature is not working!).
Anyway, I plan to fly to your country, Finland next week for commissioning! My switches are already installed on site, so I can't test the web functionalities.

Thanks again for your help
