CSV Data

CSV channel data can be imported into SimVT. Once in SimVT it is handled in the same way as other data sources, allowing you to correlate curves with matching channel names.

CSV Data file format

The CSV file format is based on the CSV format that can be exported from T/HIS using the CSV X,Y,Y,Y,Y,Y write option.

• The first header row is required and contains the names of the channels that will be imported
• The first column contains the time values (X points) and the Y value at the time is given in the adjacent columns. Note that if the Y value is empty or not a number the row will be skipped
• The word "Time" must appear in one of the cells in the first column. It marks the end of the header rows (i.e. the row below should contain time-value data)
• The "Time" row can optionally be used to defined the units of the non-ISO-MME channels. 
• The "Object" and "Location" header rows are optional and are used to group non-ISO-MME channels in the SimVT Correlation Table.

ISO-MME CSV Channel Data Example

The table below shows some example CSV channel data with ISO-MME channels defined. Note that:

• The first cell (A1) is empty.
• The first row contains valid 16 character ISO-MME channel codes for each column.
• The first column contains the word "Time" in the second row and the data values begin on the row below.
• The second row has no unit data defined as the units can be determined from the ISO-MME channel codes' physical dimension (e.g. AC is acceleration so will have units of m/s^2 (Note that units are assumed to be in SI by default. If the units are not in SI (e.g. Acceleration in 'g' or force in 'kN') you will need to specify the units in the CSV file or alternatively in the Import Config CSV).

Non-ISO-MME CSV Channel Data Example

The table below shows some example CSV channel data with non-ISO-MME channels defined. Note that:

• The first cell (A1) contains the word "Channel" - this is optional when the channel names are on the first row.
• The channel names are not valid ISO-MME channel codes so they will not benefit from the ISO-MME channel matching for each column.
• The first column contains the word "Time" (i.e. "Time | Units") in the fourth row and the data values begin on the row below.
• The "Time" row also has unit data defined as the units cannot be determined from non-ISO-MME channel codes. 
• The "Object" and "Location" rows are defined, so the channels will be grouped together on the SimVT Correlation table.
