This document specifies data protocols and data format for the communication between electronic equipment (TVE), on-board computer (OBC) of the tank vehicle and stationary equipment. This document specifies the basic protocol FTL used in the communication (basic protocol layer), the format and structure of FTL-data to be transmitted (data protocol layer) and describes the content of the FTL-data. This data protocol can be used for other application e.g. between stationary tank equipment and offices.
