If you misspells the _PLC alias_ you will get the error 'Not a valid variable name'. It cannot be distinguished whether the first name is an alias or a variable name.
For details of variable names see [mon documentation](https://docs.industrial-operations-x.siemens.cloud/access?ax:packageName=%40ax%2Fmon&ft:topicTitle=Usage+example&ax:filepath=example).
The [limitations](https://docs.industrial-operations-x.siemens.cloud/access?ax:packageName=%40ax%2Fmon&ft:topicTitle=Limitations&ax:filepath=limitations) of the `mon` tool apply here too.
> TIP: if you want the values alone set the logging level to warning with '--log warning'.
