IEC-61850 Gateways

Modbus to IEC-61850 Gateway

Modbus RTU/TCP to IEC61850 Gateway

BUE-61850 series IEC-61850 Gateways can provides both industrial communication device and solution of the whole industrial automation system,which plays more important roles in industrial control and automation,especially in the substation automation.

1.Communication function:

Protocol conversion:

Standard protocols that BUE-61850 support: UCA2,CDT,DLT645,TCP/IP, DNP3, OPC, Modbus RTU,Modbus TCP, IEC60870-5 series(IEC101,IEC102,IEC103,IEC104), IEC61850(Our IEC61850 Can work as server or client)

Non-standard protocol: DC screen,power meter,safety equipments.The different protocols of data can convert with each other in the BUE-61850

Data processing:

Digital processing: signal acquisition & transmission,anti-shake,singnal maintenance, timing alarm, quality judgment.
Analog processing: multiplication coefficient, residual cleared, anti-mutation, quality judgment,etc.

Point table custom and information split:

In the BUE-61850 system it provides different data forwarding point tables,different channels’ protocol  can forward and each uses different data forwarding table. The same data can be submitted to the upper machine in the form of different value.

Dual channel processing:

BUE-61850 Supports the system with dual channel mode and the upper machine communication, including fully redundant dual channel way, communication link redundancy, main equipment and so on.

Measuring point self description:

BUE-61850 supports self description of data point, which is convenient for maintenance and debugging.

2.Advanced application:

Data calculation:

BUE-61850 provides standard calculation formula and take the processing of data in the way of  addition, subtraction, multiplication, division, logic judgment (including greater than, less than, equal to, is not equal to, greater than or equal to, less than or equal to, logic and logic, logic or, not), sine, cosine, square root, take maximum, minimum, average calculation.

Equipment automatic control can be set up:

BUE-61850 provides the setting of basic control logic, timing or logical calculation according to the real-time data of on-site equipment start-stop switch quantity control and analog control, such as temperature, pressure, etc.

Advanced equipment control integration

3.Management function:

Debugging management:

BUE-61850 provides all kinds of debugging methods and management, including remote debugging, intelligent device simulation, data simulation, control block, data browsing, message and debugging information monitoring, message storage and playback, flow rate and bit error rate statistics.

Equipment management:

Equipment management functions includes: remote diagnosis and maintenance, hardware watchdog, custom information indicator, main standby switch management etc.

Time synchronization:

BUE-61850 can receive the time code from time servers,it can synchronizes time in the format of IRIG-B and NTP/SNTP.

4.System feature:

Low latency: 5 to 50ms latency.

Strong data processing ability.

Reliable communication management
