The outer layer of aluminum foil covers the entire conductive core, serving to counteract high-frequency interference. 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. Before digital instruments begin to operate, they must be set with measurement system parameters and communication parameters. 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.

Computer is connected to the converter rs232 rs422 ATC - 105. Converter is also connected to external power, supporting RS485 port. 1. RS232 - Can accept local power or can be cabled to run powered from 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 cabling of the industrial communication systems (Modbus RS485) is different in some ways from the cabling used for power cabling and the electrician may experience some difficulties if he is not an expert in Modbus communication networks.

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. So you can have a reliable, low-cost solution to a heating, ventilation control unit. Paperless chart recording is a much more user-friendly solution with an interactive dialogue simplifying both setup and operation procedures. 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. 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. Cable jacket: Made from high-quality PVC, the outermost jacket layer has high elasticity, helping to protect the cable from strong environmental impacts. The POE version makes this a single cable connection that will allow monitoring from anywhere in the world; anywhere with internet access that is.

Control and monitoring systems: A single pair of rs485 signal cable can connect up to 32 devices, with a signal transmission distance of up to 1200m. Therefore, using rs485 cables is an ideal choice for industrial control and monitoring systems, especially those with large-scale and high dispersion. In a computer system, SCSI-2 and SCSI-3 may use this specification to implement the physical layer for data transmission between a controller and a disk drive. It can drive things 1200 meters, which RS - 232 is about 15 meters maximum. One of the key advantages also is that RS-485 can drive data a long distance. One other key advantage that most people using 485 is, the better noise immunity. By default, all 720 series key pads come with a standard set of commands which can be used to integrate with existing applications or used to build the metal keypad into new application developments. It also has a keypad display attached and the other required hardware interfaces like the RS232, RS422, RS485 etc. This server can customized beforehand to carry out the pre-defined tasks.
