Features

8-way RS 485 input

Data output method:

-MODBUS RTU/ASCII

-Ethernet TCP/IP

The two bus output modes are parallel and do not affect each other

Output mode of MODBUS bus

RTU/ASCII is optional. Capable of transmitting characteristic values, real-time waveform data of modules, as well as physical quantities such as module status and alarm status

Key phase signal adjustment function

Redundant power input

Adopting the standard 19” Frame module

The MMS6823 EPRO module is a high-performance device used for collecting and transmitting vibration data of rotating machinery. It provides accurate measurement and analysis of vibration signals, enabling early detection of potential issues and the development of effective maintenance plans

MMS6823 continuously accesses the MMS6000 module connected to the RS485 bus to achieve real-time data acquisition function, and converts the received feature value data, alarm and module status data into standard MODBUS protocol and TCP/IP protocol outputs

MMS6823 is connected to the RS485 bus of MMS6000 turbine monitoring and protection system through RS-485 communication port to obtain real-time data of various measurement modules of MMS6000 system. Due to the fact that the data is directly taken from the measurement module without intermediate processing, it has unparalleled accuracy compared to other sampling methods. The system adopts synchronous integration

Collect data in a periodic manner, with optional sampling points and a maximum sampling point of 1024. Can collect vibration data and related process parameters for start/stop (transient) and steady-state. The system obtains dynamic signals from tile vibration and shaft vibration, and static signals from shaft displacement, eccentricity, and differential expansion measurement modules. Obtain the speed and key signal of the equipment from the speed module

The data collection and communication service program adopts multi-threaded technology, and all data read and write operations of each MMS6000 module channel are parallelized. Each serial port is completed by a separate thread to ensure synchronization of data between channels

According to the output, it is divided into Modbus and TCP/IP communication. Real time data is sent to the MMS6851 server through a local area network according to the TCP/IP communication protocol, and the received real-time data is converted into standard MODBUS protocol (RTU or ASCII) for communication use in DCS or DEH systems

Modbus protocol: The first serial port RS232 is the Modbus communication port, and MODBUS output can choose MODBUS RTU or MODBUS ASCII protocol mode. The protocol mode can be set by the Modbus field in the XML configuration file. The feature value data, alarm and module status data received from MMS6000 can be accessed by DCS, DEH and other systems connected to MMS6823

TCP/IP protocol: MMS6823 converts received feature value data, waveform data, alarm and module status data into standard TCP/IP protocol, which can be output through Ethernet TCP/IP interface. These data can be accessed and displayed by the vibration analysis system connected to them. The TCP/IP network interface is a standard RJ45 interface, using standard network connection cables. MMS6823 can automatically detect the TCP connection status. If the connection is disconnected due to software or hardware reasons, the listening thread can immediately detect it and make corresponding instructions. The TCP port allows a client connection to listen, complete system configuration, debugging, and data communication. The IP address of MMS6823 can be flexibly set according to needs

Application Fields

The MMS6823 EPRO rotating machinery vibration monitoring data acquisition and communication module is widely applicable to large and medium-sized rotating machinery in industries such as power, petrochemicals, coal mines, and metallurgy, such as steam turbine generators, water turbines, electric motors, compressors, pumps, and fans
