Running the latest nightly build.

```auto
Traceback (most recent call last):
  File "<buffer>", line 2, in <module>
AttributeError: 'com.inductiveautomation.ignition.designer.gui.tool' object has no attribute 'opcua'

```

Using the example code:

```auto
result = system.opcua.callMethod(
        "Ignition OPC-UA Server",
        "ns=0;i=2253",
        "ns=0;i=11492",
        [1]
    )
print result[0]
print result[1]
print result[2]

```
