The cable to be used is a shielded twisted pair (telephone type). However since only a true RS485 network can have addressable serial RS485 devices, the RS232 converter needs to be addressable either by software or by DIP switches when using it in this type of configuration. Confirm hardware connections including serial port devices, and check if your gateway and energy meter are correctly connected. After the experiment is completed, the class can view statistics from the recorded data including instant, average, min and max values. The foreword to the standard references The Telecommunications Systems Bulletin TSB-89 which contains application guidelines, including data signaling rate vs. The basic rate is 54 Mb / s, but in practice works best in the range of 20 Mb / sRadio network in the case of district heating has proven to be an excellent alternative to other types of communication systems and in this application is an innovative solution.

Power to heat buildings is via 215 substations, of which 191 are connected to the Central Heating Plant, and 24 to the boiler room Podczele. 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. It contributes to the reduction of transmission losses, thus increasing network reliability and comfort of heat consumers. 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.

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. The VR-18 Paperless Chart Recorder can be connected to a PC with an Ethernet cable allowing students to use the Brainchild's FREE software, allowing for streaming live data or downloading the data to an Excel spreadsheet to further manipulate the information for reports and assignments.

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. Got rid of the problem lay long lengths of cable between receiver points and the heating plant, rs485 cable and obtained an easy and convenient access to the substation.The control system was designed and built node in cooperation with the company TechBase Sp. The POE version makes this a single cable connection that will allow monitoring from anywhere in the world; anywhere with internet access that is. A single complex experiment or several individual experiments using multiple sensors can easily be monitored given the Brainchild's capability to record real-time inputs during one session. The Brainchild's programmable alarms and messages give instant notification of high levels of temperature and other critical events. SMTP - the units can be ordered with the firmware option that sends SMTP messages to a central 'mail server'as an alternative means of integration. It can drive things 1200 meters, which RS - 232 is about 15 meters maximum. RS-485 can send data 1200 meters on cable. 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).
