Hi, I want to know the OPC Connection State (Connected or Disconnected). I am searching for a tag but didnt found such tag. I want to generate an alarm when OPC connections is lost. How Can I do this? Any idea? Thanks. ---

Every OPC connection has a Gateway System Tag that indicates its connection status. [https://docs.inductiveautomation.com/display/DOC81/System+Tags#SystemTags-GatewaySystemTags](https://docs.inductiveautomation.com/display/DOC81/System+Tags#SystemTags-GatewaySystemTags) ---

I can see only these system tags. I think I am using lower version 7.3, it is not available for this version. any idea for 7.3 version, how we will get OPC Connection Stae? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/b/1ba28480d7841526b2a464665d7dc208beae1f01.png) ---

Sorry, I don't think there's anything that can help you out in 7.3. Too old. ---

Actually, it might be worth seeing if `system.opc.getServerState` exists in 7.3: [system.opc.getServerState - Ignition User Manual 7.9 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC79/system.opc.getServerState) ---

How about this function? will it work for me? Actually I am trying but not working. if((runScript(“system.opc.getServerState(‘Matrikon UCS’)”,5000)) = “CONNECTED”, “1”, “0”) ---

Not tried on timer script. I tried on expression tag. How I will get Name of OPC Server connection? I am not sure I am passing correct value or Not. ---

Looks like you have a single connection called "Kepware". Does the "Configure" area show the same name? ---

Yes In Configure it is showing "Kepware". and I am trying to create one Expression tag like this but it's not working ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/0/b/0bfc70b28da9e33e1598e83823a1ce3f1b199a7a.png)
