For support related issues, we also include information related to temperature sensor measurement,
temperature control type, light control type and type of PLC3 used in the data output (see below). The
last column labeled “Status” is there to report any errors that may have been reported during a
measurement. Normally this field is empty with the Photosynthesis data output. If an error is reported it
will show up in this column.
