The technical field to which the invention relates
The present invention relates to field devices used in control systems and monitoring production processes, and in particular, to the field devices that use wireless data.
The level of technology
Field devices are used in systems of control and monitoring of industrial processes and automatic control of industrial and chemical processes. Field device transmits data representing a physical parameter such as temperature, pressure, position etc. in the computer or the host process control, and may also receive control signals that are necessary to the field device to perform an action, such as opening or closing a valve.
Field devices located in hazardous (classified) areas, such as flammable or explosive atmospheres. Field device located in a flammable or explosive environment can as protection to have intrinsic safety. Thus, the device consumes energy minor and cannot cause a spark, which will cause fire or explosion.
Initially, the field devices transmit data to and from the host through the wired network. Provo�networks may also be supplying power to the field devices. Supply energy over a wired network itself may be limited by the level of intrinsic safety, by supplying power to field devices located in hazardous (classified) area.
Wireless data transmission, meanwhile, is becoming more popular. Wireless field devices include an antenna that sends and receives data wirelessly. The antenna is housed in a cover, which is traditionally made of insulating material, thus, the antenna is separated from the environment.

Wireless field devices for use in hazardous (classified) areas commonly used capacitors or other electric�patients under stood the antenna circuit in the signal path. These circuit elements operate as a high-pass filter that in case of a short circuit of the antenna allows you to generate and pass to the antenna only pulses with low energy. Such pulses with low energy can cause sparks.
Traditional wireless field device has a permanently attached antenna. The antenna can be removed when the wireless field devices in hazardous (classified) area.

FIELD: information technology.
SUBSTANCE: programmable logic controller (PLC) protocol converter allows a supervisory control and data acquisition (SCADA) system to effectively communicate with a PLC using a desired communication protocol, particularly in cases where the PLC does not support the desired communications protocol. A first process may be configured to continually read PLC addresses, one at a time, using a communication protocol supported by the PLC. The first process may store the data values in the shared data array within program memory. Thus, the first process provides data from the PLC, as specified in the configuration file. At the same time, a second process may be configured to process the data in the shared data array according to a second communication protocol, e.g., for communication the SCADA system.
EFFECT: high efficiency of communication with a programmable logic controller.

FIELD: food industry.
SUBSTANCE: system for production of multiple types of food products that may be differed from each other in terms of configuration and/or composition; the system contains a container (2) for transportation of multiple moulds (M) placed on it along multiple work places (S1-S16). Each mould (M) is equipped with a corresponding electronic ID device (T) including memory devices (4). Each work place (S1-S16) is equipped with at least one corresponding electronic unit (A-E) including a processor (9) connected to the memory devices (10) and at least one antenna or a similar device (15) and is designed to be able to read information or data and/or to record information or data to the memory devices (4) of the mould (M). The initial input work place (S1) transfers or records to the memory devices (4) information on identification of products (P) moulded in the mould (M) while the electronic unit of each additional work place (S3, S6 …) can selectively modify the execution mode, of at least one operation in accordance with processing information read from the memory devices (4) wherewith each mould (M) passing through the work place is equipped.
EFFECT: according to the invention the system allows to adapt the process of moulded products production in real time in a flexible manner and in a flexible way on the basis of the specified requirements.
