product description

ROMI measurement and control LM-EMS-201 energy collection terminal is an advanced field collection controller, which communicates with field equipment and instruments through advanced communication methods. The ultimate solution for enterprises is to enable automatic transmission of energy data from remote terminals to the energy collection master station or SCADA system. LM-EMS-201 not only has most of the functions of traditional RTU, but also provides more communication options, more powerful data processing and control capabilities, making it a truly open controller. The application range of LM-EMS-201 is far beyond the traditional scope, and it can be widely used in various industries. Its functional diversity, high cost performance, high performance and scalable architecture have been universally recognized. Provide multiple communication interfaces and support multiple communication protocols, including Profibus DP, Profinet Master, Profinet Slave, InterBus, ControlNet, Ethernet / IP, DeviceNet, CANOpen, ModBus Plus, ModBus, ModNet, IEC101 / 104, DNP 3.0 and other protocols And non-standard protocol self-programming Comx, Socket, etc., can achieve communication with various measuring instruments on the site; Provide high-speed 10 / 100M Ethernet communication interface, support ModBus TCP / IP, DNP 3.0, IEC104 communication protocol, except In addition to the station connection, it can also be used to communicate with other SCADA systems and third-party software; With protocol conversion function, no matter what communication protocol is used with the field instrument, the energy collection terminal can be converted into the efficient DNP 3.0 protocol or Modnet, IEC014 Protocol to communicate with the upper-layer system; provide powerful expansion capabilities, can access discrete I / O signals on-site through the built-in I / O modules, and also can be accessed through I / O racks or independent I / O modules Extend external I / O module for field data collection and control; support built-in webpage, firewall, access control, remote Multiple functions such as diagnostics, remote maintenance, clock timing, and controller routing are used for remote programming and security control. Built-in flow accumulation calculation module can perform flow compensation calculation. Powerful communication capabilities can be built-in GSM / GPRS module to achieve GPRS communication, and support a variety of communication methods such as fiber access and DDN can be mixed and used simultaneously; Has a high clock frequency, computing and communication speed is very fast, can meet the high real-time requirements of field data; memory capacity and data storage capacity is very Large, the use of IO points is almost unlimited and can reach tens of thousands of points, which can fully meet the communication needs of large data volumes of multiple systems. Designed from the perspectives of security, ease of use, and easy maintenance, the main performance parameters are not less than the following indicators: The CPU uses a 32-bit processor, the main frequency is not less than 400MHz, and supports floating-point operations. The processor has complex logic operation capabilities and multi-level PID control capabilities. With good control performance, can fully meet the technical requirements of on-site monitoring, can complete all tasks (including signal acquisition, control, multi-channel traffic calculation, etc.) within 1s; have data storage and recovery capabilities. The standard memory is 64M, up to 128M. It can store historical data and events locally in case of communication interruption and transmission failure. The data storage capacity is not less than 200,000, and the data points to be stored can be customized. After the communication is restored, the data can be automatically restored to the historical database of the monitoring system to ensure the integrity of the data of the entire monitoring system. It has strong permitting capabilities and is seamlessly compatible with most traditional communication methods (radio stations, PSTN, etc.), and supports A variety of modern communication methods (such as GSM, GPRS, optical access and DDN, etc.). Multiple communication methods can be mixed and used at the same time; Modular design is adopted for flexible expansion; It has rich communication interfaces, with a maximum of 4 RS485 serial ports, 2 RS232 serial ports, and 3 Ethernet communication interfaces. It supports standard serial ports and TCP / IP communication mode; Support multiple communication protocols. On-site third-party intelligent devices can be connected to data acquisition equipment through various standard protocols such as ModBus, Profibus, DNP 3; also support non-standard serial ports or Ethernet free communication protocols. Programming; With fault response and self-test functions, online diagnosis to monitor equipment operation; Other parameters: Working power: AC 220V ± 20%, DC 9-30V; Working environment conditions: Temperature: -20 ~ 70 ° C, relative humidity : ≤90%; compressive strength: 2KV; antimagnetic;
