10 Amazing Rs485 Cable Hacks > 자유게시판

From there, the data logger insures that their processes are completed at the correct parameters and can also send out alerts if the data exceeds preset levels. CAS DataLoggers together with high-quality manufacturer Brainchild has the solution with the VR-18 Paperless Chart Recorder, a high resolution (true VGA, 640x480 pixels) 18-channel data logger featuring an infrared detector, plug & play I/O card, high flexibility, and user-friendly operation, all in a compact size. Using the recorder's benchtop/portable configurations and panel mount, the VR-18 is an effective stand-alone solution to monitor, record, and evaluate processes in the laboratory, classroom or out in the field. 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. 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.

Configuration and data accessibility were a snap: the FieldLogger's user-friendly configurator software was accessible by Ethernet, USB or RS485, and also provided means for online monitoring, downloading of all logged data, and quick exporting to spreadsheets and other formats. Teachers can set up the display to a projector, allowing an entire class to view the data representations, and students can print the data collected from any of the display formats. After the experiment is completed, the class can view statistics from the recorded data including instant, average, min and max values. 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). With an RS485 interface, the FieldLogger could act as a Modbus RTU master and read registers from other slaves, and as a master, it was able to read and log up to 64 registers from Modbus slaves. Computer is connected to the converter rs232 rs422 ATC - 105. Converter is also connected to external power, supporting RS485 port.

The RS485 interface allows the creation of multipoint networks. 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. 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. 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. 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.

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. Able to handle multiple inputs, the datalogger provides useful information for experiments involving the heating of various liquids at a variety of volumes. 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. It can drive things 1200 meters, rs485 cable which RS - 232 is about 15 meters maximum. One of the key advantages also is that RS-485 can drive data a long distance. Transformers can be of different types, depending on the assembly system: a through cable or a cable with a coiled primary, transformers for assembly on horizontal or vertical bars. Flexible and rigid cables or bars for power transport can be installed in a power panel. 1. RS232 - Can accept local power or can be cabled to run powered from port.
