Under some conditions it can be used up to data transmission speeds of 64 Mbit/s. It contributes to the reduction of transmission losses, thus increasing network reliability and comfort of heat consumers. In addition to the ease of integration, minimum requirement of processing power and reliability of the connectors further helps to favor these serial over Ethernet communications.A device server is used to control the whole setup via a networking technology. 12 V. What RS-485 does, it just needs 5 V because it just swings over to 5 V at the output. RS-485 can send data 1200 meters on cable. Also enables the analysis of long-term work nodes modbus snmp based on charts and collected the data collected. Capabilities are used in the converter system made according to the following statement: monitoring parameters NCP series controllers, Modbus TCP network, handling controls: MN300, MN440, MN500, MN620, and heat meters - Mbus, the possibility of a software change controls, administration of the converter through a local or external PC terminal (TELNET), downloading and saving configuration files and files with FTP-client data (data downloaded, read and written by the application visualization once a day - which ensures the continuity of their records in the form of graphs), data storage (512 kB RAM with battery backup - data are recorded every 10 min, for 72 hrs.).Control and monitoring heat in Kolobrzeg installed by a company PUP SPIN SA in cooperation with the company TechBase Sp.

Ltd., which supplied the necessary equipment to communicate with the visualization application controls and heat meters, mounted on each node. In connection with the need for rapid response by the central location for all types of heating systems failures and malfunctions substations located in many parts of the city, MEC Kolobrzeg decided to execute a remote system monitoring and control of heating systems.The monitoring system is based on Citect SCADA visualization software v. 6.0. This software is a standard for the entire heating system to monitor the MEC Kolobrzeg.Delivered new server running under operating system Windows Server 2003. Visualization of the nodes attached to an existing application that supports the entire heating plant. TSB-89A, Application Guidelines for TIA/EIA-485-A does not recommend using star topology. If a star configuration is unavoidable, special RS-485 repeaters are available which bidirectionally listen for data on each span and then retransmit the data onto all other spans. Star and ring topologies are not recommended because of signal reflections or excessively low or high termination impedance. The EIA once labeled all its standards with the prefix "RS" (Recommended Standard), but the EIA-TIA officially replaced "RS" with "EIA/TIA" to help identify the origin of its standards.

Additionally, the Brainchild's standard Ethernet and optional RS-232/RS-422/RS485 communication enable users to access data onsite from a remote location via the RS serial interface or Ethernet networking. It basically goes to a remote PC that has all the pricing information and it sends the data back to you. They just send it to remote PC and basically send it back. RS485 communication cable, then connect back of the DVR panel. On the other side we also have converter RS232 - RS485 ATC - 108N, via the RS232 port is connected to cash or other device with RS232 port. Computer is connected to the converter rs232 rs422 ATC - 105. Converter is also connected to external power, supporting RS485 port. These devices allow you to view and modify the parameters of heat controllers, connected to the RS485 port via the communication protocol and the NCP to monitor the parameters of heat meters (Mbus), connected to RS232 port via a converter RS232/Mbus (M-bus master).

The communication is based on Modbus TCP converters to Satchwell ™ MN300, MN440, MN500, MN620 (485 NCP protocol) type I-7188E2-S-NCP. As a communication protocol Modbus TCP is selected as the Ethernet due to its versatility, the continuing growth and various protocol converters, has now become the standard in industrial solutions.Built a separate communication network, based on radio Ethernet (WLAN) 802.11a, which uses a frequency of 5 GHz. The main problems that arise during the testing phase can be due to incorrect installation of instruments and accessories. One of the main reasons why this standard is used it's because wireless rs485 is able to send data a long distance. One of the key advantages also is that RS-485 can drive data a long distance. Educators and students working in laboratories and classrooms in universities across the country often use older paper chart recorder technology to record their live data onto hard copy. The Brainchild also entirely eliminates the need to search through large amounts of hard copy records to find earlier data. The Brainchild's built-in display allows teachers and students to get a clear review of all measured data on its 6.4'' VGA Color LCD displaywith flexible screen configuration. Thanks to paperless chart recording technology; students and teachers are now able to clearly and conveniently visualize their experimental data.
