The protocol supports reading data from electrometers (active and reactive energies) that were collected by ABB Microscada and published via files.
The files are expected to have a name in a format coding both the date and the time Dyyyymmddhhmi.CSV, e.g. D201706301247.CSV.
The files are read with the time parameters (period, delay) configured on the station's Time parameters tab.
The protocol only supports data readout.

Supported value types of I/O tags: Ai.
I/O tag address is an integer 16-bit number (1-65535) specified as a decimal number or as a hexadecimal number with a hash at the beginning (e.g. #0A) .
It defines a number of electrometer, which is written on every line of a data file.
This is an example of the first 15 rows of a specific file (I/O tag addresses would be 1-15):
