In SAFE you can output metadata with the
Metadata block. It will output a specific metadata value each time the value changes. This can be useful for
other block or for visualisation. In order to use the block you must have created a metadata field. Note that it will output every time the value changes.
For more controlled outputs look for the metadata output in Measurement.
The output is
1x1 metadata value.
Name specifies the name of the block.
Field name is the name of the metadata field that you want to output. If no metadata field has been created it will state
When a field has been created it will automatically change.
Current Value is the value of the metadata field at the present time. It will change every time the state changes
Outputs specifies the number of output(s) the block will have. Each output will output the same value.
