The automation of a process consists in providing technological means for its operation and control, such that the system as so conceived is enabled to deal with those situations for which a proper command has been implemented. The intervention of the operator is often necessary to ensure complete control of the process through the specification of operating orders, which take over control of all or part of the system. Measurements (readings) of the parameters of the process are effected by the sensors which obtain the information, put it into the required form, and transform its physical nature. At the other end, commands are transmitted to the process by actuators. This transmission is generally accompanied by a transformation of the physical nature of information. The command unit processes the actions from the me
