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. Able to handle multiple inputs, the datalogger provides useful information for experiments involving the heating of various liquids at a variety of volumes. However, this makes it difficult to search through the information and organize it all. The Brainchild also entirely eliminates the need to search through large amounts of hard copy records to find earlier data. One of the key advantages also is that RS-485 can drive data a long distance. In a three-phase system, instruments can be installed that measure the single electrical parameter, one per phase, or a voltmeter and a current can be installed with the voltage and current switches, allowing the measurements to be displayed in sequence. After having defined the type of instrument best suited to the needs, if the measurement is performed by indirect insertion, the accessories of the measuring system, such as current and voltage transformers must be chosen with care.

The sizing of the measurement system begins with knowing the main parameters of the plant; in particular, from the characteristics of the protection switch, the type of distribution system, the rated current, the rated voltage and the type of busbar can be known. The instrument must be selected according to the type of distribution system. A current transformer suitable for the application must therefore be selected. The parameters chosen for a current transformer are not only the rated current, the secondary current and the power, but also the type of assembly. 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.

Choosing an analog instrument ensures good reading stability, due to the mechanical inertia of the needle and the fact that the reader immediately knows whether the instrument is operating normally or if the reading is out of range. Capable of performing mathematical operations in the input channels, this high-speed reading and logging device utilized a 24-bit A/D converter enabling up to 1000 samples a second and a suite of connectivity options including a 10/100 Mbps Ethernet interface that allowed for access through a browser (HTTP), FTP (client and server), e-mail sending (SMTP), SNMP and Modbus TCP. 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. Most of the serial based devices can be easily integrated with the Ethernet protocols. 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. Data retention is no concern, specified at a minimum of 10 years with zero power data retention. 1. RS232 - Can accept local power or can be cabled to run powered from port. In multifunction instruments, not only the cables connected to the measurement, rs485 cable but also the RS485 serial port and the analog and digital inputs and outputs must be wired. Class I must say i, Category A man or woman regarded detrimental sites. So it's better noise immunity. Because of the differential signal, any noise is subjected externally to the cable is basically subjected to both cables.
