Enigma Posts: 49 Rating: (18)	Dear Expert, I have 1 AS with 2 standalone OS stations and 1 CAS system. My requirement is, when any of the OS goes down, archive data of the same is lost for perticular time period on that machine. But same data is logged at another both OS and CAS system. I want to determine Status of S7 connection. Regards, Enigma

Krrish !! Posts: 73 Rating: (6)	Dear Enigma, You could use the "Report System Error' functionality in Step7 hardware configuration and make a compile of your AS-OS to generate the system messages in your project. Alternatively, you could use one of the following: SFC13 - To get diagnostic information of profibus slaves SFC87 (C_DIAG) - To get connection status of ethernet connections. Please refer the link below for information on how to configure C_DIAG in your user program https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&objId=27779025&nodeid0=10805388&load=treecontent&lang=en&siteid=csius&aktprim=0&objaction=csview&extranet=standard&viewreg=WW Hope this helps. Regards, Krrish !!

Again as krish said you can use reprot system error as alternative. Have fun....

In such cases if the if your HMI is powered oFF, it has no meaning. But if these status are used in the PLC logic, to stop something then that means lot. Here is one link But if you want Just your PLC is connected with HMI/SCADA then a simple Heart-bit(CPU Clock bit) is enough.

ABN Posts: 212 Rating: (12)	Hi, If you are using WinCC 7.0 or PCS7 V7.1 there is no need to call any special logic. From WinCC 7 onwards WinCC can be used as a service. When WinCC is in RT, there is an icon created on tool bar near time. Clicking on the same you can get entire details of all simatic machines installed on that machine. if Its connected online and in RT then Green Indication or for error RED indication. So, if you feel you can use the same.

The above said explanation given by ABN is for Server-Client Set-up But the requirement is of standalone system While WinCC is in RT, In WinCC Explorer Tools -> Status of Driver Connections
