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. Also enables the analysis of long-term work nodes modbus snmp based on charts and collected the data collected. 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. 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). 1. RS232 - Can accept local power or can be cabled to run powered from port.

The symmetrical pin layout of the RJ11 sockets on the Unitronics PLCs allows an easy way of interconnecting the PLCs with both RS232 and RS485 communications. In multifunction instruments, not only the cables connected to the measurement, but also the RS485 serial port and the analog and digital inputs and outputs must be wired. This connection may be used to limit the common-mode signal that can be impressed on the receiver inputs. Builds on the original Bobuino, makes USB/Serial easier to assemble, adds lots of connection options besides just shields - signal/power/ground available at each pin location. The POE version makes this a single cable connection that will allow monitoring from anywhere in the world; anywhere with internet access that is. Got rid of the problem lay long lengths of cable between receiver points and the heating plant, 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. Below points describe to connect these network keypad 735 series and 720 wall mount. The rubber buttons offer limited liquid resistance while the wall mount unit can be for indoor use as the 720 SM, shown below or, mounted in a weather resistant enclosure - 720 SMO.

The 735 series are desk top terminals and the companion 720 wall mount units. Available with male headers, female headers, or screw terminals. Barrel jack or screw terminal options for providing coil power & LED. Two auxiliary power cables should always be connected for digital instruments. Some measuring instruments have bar indicators that show the current level as a percentage of the set full scale. The analog instrument indicates the point of the measurement scale on which it is located, indicating the upper and lower limits. 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. If not only the electrical parameters are to be monitored, but also the energy consumption, rs485 cable measuring instruments which also have active and reactive energy metering should be selected. For example, thermochemistry, the study of heat and energy associated with chemical reactions or physical transformations, is a perfect lab experiment application for the Brainchild. 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.

After the experiment is completed, the class can view statistics from the recorded data including instant, average, min and max values. Students view the collected data in the display format or choose additional formats including vertical trend, horizontal trend, bar graph, and numerical. Users can browse through the alarm list or acknowledge alarms easily via function keys on the vertical bar. The Brainchild's programmable alarms and messages give instant notification of high levels of temperature and other critical events. This high performance and high connectivity equipment also offered personnel easy configuration and operation to get the project underway as quickly as possible. The recorder offers a fast sampling rate within 200msec for all channels and high accuracy with up to 18 universal input channels to connect to a variety of sensors commonly used in lab environments including DC voltage output from specialty sensors and thermocouples/RTDs to log temperatures with extreme precision. 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.
