For each tag value that is logged with the wide table format each point will have a corresponding field name. Specify a field name up to 64 characters in length, do not use special characters or spaces that will be incompatible with other third party reporting systems.
Do not use the names DateTime or Date as these have special meaning for many database queries.
Note: To specify non-standard characters and spaces put [ in front of the field name and ] at the end of the file name. Example: [my.field-name value].
