I'm planning to use SNMP OPC Server for monitoring the X208. Is this a good choice? And do I have to purchase the SNMP OPC Server ? 2) Moreover, if I wat to do the diagnostic for 6 items of SCALANCE X204-2 which are in the lower layer. Can I do the diagnostic and display the information on WinCC? Best Regards anuchisa Attachment Draft Scalance Network Architecture.pdf (364 Downloads)

Is not a problem, it just means that you should give all switches an IP address in the same range as the IP address of the server. And the server will be able to speak SNMP with all switches. The SNMP OPC server requires a license. There exists a basic (20 IP addresses) and an extended version. Also the operating system used on the server is important to order the correct item.

Do we have to use Windows Server 2003 or 2008 (not XP or 7) for this WinCC server ? Thanks anuchisa

RSE doesn't give not exactly the same information or doesn't present it in the same way as SNMP. First step is to integrate the switches in the HWconfig of a PLC, by connecting them to the Profinet network of that PLC. The switches will behave like Profinet IO-devices. In the settings of the switches in Step7 you can set each individual port to "monitor", which means that a change in the link will cause the call of a diagnostic OB. Second step is to generate the RSE program blocs by running the wizard in HWconfig (see options ==> report system errors). And to load the generated blocs in the PLC (+PLC restart). RSE also generates alarm texts for visualisation. Third step is to integrate the alarm messages in WinCC. This is explained here: http://support.automation.siemens.com/WW/view/en/22727527 A useful document to look at is this one: Diagnostic Methods for PROFINET Network Components (PROFINET IO, SNMP, WBM) http://support.automation.siemens.com/WW/view/en/21566216 2) Regarding the OS choice, you can use both (XP or Win7). But the SNMP OPC CD2008 is required for XP (this version does not support Win7) And the CD 8.x is required for Win7 (and is not OK for XP). Therefore my comment to order the correct item.
