'''''Data transfer protocol''''' - a set of specific logical-level rules or conventions that govern the exchange of data between different programs or devices. For TD-150, the main transmission protocol is '''LLS via the RS-485 interface'''. The TD-500 sensor also supports '''MODBUS''' protocol, [[MODBUS ТД-500|description]].

Without it, it is impossible to control transportation, to determine the coordinates of the vehicle location. It collects information from sensors and on-board system of the vehicle, and then transmits it to the device/server, which belong to the controlling specialist.

===== '''<big>Ladder shape tank's tank calibration</big>''' =====
When calibrating, it is necessary to create two tables, one for "'''FLS 1'''" and the second for "'''FLS 2'''"
Let's assume that the calibration step is 10 liters.
At the beginning of calibration, when the fuel is in the "'''Red Zone'''", the level changes will only occur on "'''FLS 2'''", so we directly add calibration steps of 10 liters to the table for "'''FLS 2'''".
When the fuel is in the "'''Yellow Zone'''" changes will occur on both "'''FLS 1'''" and "'''FLS 2'''", during this period we record changes in both tables with half a step, that is, we also fill in 10 liters, but we record 5 liters in the table of each sensor.
When the fuel is in the "'''Green Zone'''" the changes will only occur on "'''FLS 1'''" so we directly add calibration steps of 10 liters to the table for "'''FLS 1'''".
On the platform "'''FLS 1'''" and "'''FLS 2'''" are started as separate sensors with their own tables and then a third virtual sensor is created with the sum of liters for two sensors, an example of starting two FLS on the platform is shown [https://docs.google.com/document/d/14p9GYmY0D1Wjz0ZfJXO-soVfxRBP7EiY7TgibD6vmZQ/edit?usp=sharing in this instruction.]
