Try the [IALabs Scripting Module](http://www.inductiveautomation.com/forum/viewtopic.php?p=37950#p37950): system.opc.browse

FWIW, the IALabs Scripting Module functions are built in to Ignition 7.7.

Seems like example 1 in the docs for system.opc.browse() does this…

you have to specify the OPC server to browse with system.opc.browse(opcServer, device, folderPath, opcItemPath) according to the docs. I wanted a list of all current OPC Servers available. Thanks

Sometimes parameters to a function or method in computer programming are optional. While the [documentation](http://files.inductiveautomation.com/modulemarket/1/46/version/121/doc/system_opc_browse.htm) may be a little lacking in saying that it is optional, you can easily see in the first example that it is optional. Just try it out:

Example 1: Browse every OPC server

```auto
tags = system.opc.browse()
for row in tags:
    print row.getOpcServer(), row.getOpcItemPath(), row.getType(), row.getDisplayName(), row.getDisplayPath(), row.getDataType()
```

UPDATE: Here’s the code to get the list of unique servers:

```auto
tags = system.opc.browse()
servers = []
for row in tags:
    server = row.getOpcServer()
    if server not in servers:
        servers.append(server)
print servers
```

I saw that thanks, but when i try example 1 i get an error: CANNOT BROWSE, SERVER IS FAULTED. The problem is, none of my OPC servers are faulted.

pretty weird

I had no problem copy/pasting example 1 this morning. You might try contacting tech support to see why you’re having issues.
