Vertiv™ NetSure™ Control Unit (NCU) User Manual
The Epoch Time field is the sample time as the number of seconds since Jan 01, 1970 UTC. It is not enclosed in quotes.
The Status field is the return status of the request. The possible values for this field are listed below. These strings are enclosed in
quotes.
“OK”
“No data in this time range.”
“The starting time and/or ending time is invalid.”
“The request is not understood.”
“Some requested signals are not available.”
The UserKey fields are the user keys, which were specified in the input request. The user keys are returned in every row in the
response. They are always the last three columns in the response.
If a key is not present, then the data field in the output is empty. For example, if only ukey3 is specified, the output for the keys would
be ,,<ukey3>. If no keys are specified, the output for the keys would be ,,.
The rows in the response always include the same number of columns (that is, the same number of comma’s). The number of
columns (comma’s) is the same whether the status is OK and data is provided or the status is not OK and no data is provided. If the
status is not OK, the response will be like:
7/1/2014 19:07,1404241623,”No data in this time range”,,,,,123,abc,foobar
Data Values
The data values in the response are selected using the Data History in the NCU. The signals that are returned in the response are
selected in the configuration files and are cannot be changed directly by the user.
The display format specified in the signal’s configuration is used to format the value in the response.
The sampling signal can be a virtual (calculated) signal.
The following data types are supported: LONG, FLOAT, UNSIGNED LOG. ENUMs are not supported. Signals which are not in one of
these formats are not included in the header line or the data. These signals are skipped.
The data in the response contains one row for each minute between the starting and ending time specified in the request.
The Storing Interval can be different than 60 seconds.
The data value in a row is the data at or before the one minute interval for that row.
Example: System Voltage is sampled every 5 minutes. The samples are:
54.2V at 12:10.10
54.4V at 12:15.10
The data is request from 12:14 to 12:17. The data in the response would be:
12:14.00… 54.2…
12:15.00… 54.2…
12:16.00… 54.4…
