DLT645 and IEC104 are currently the most commonly used multi-function energy meter communication protocols, and system transmission mostly uses serial communication. Rate device and handheld unit
for multifunctional energy meters in local systems
(HHU) or other data terminal equipment performs point-to-point or one-master-multi-slave data exchange method, which stipulates the physical connection, communication link and application technical
specifications between them.
OPC UA is the next generation OPC standard. By providing a complete, safe and reliable cross-platform architecture, it is the only mainstream direction of industrial IoT communication protocols.
During system integration, their data interaction must be realized. Therefore, BLIIoT's BL101 DLT645 to OPC UA gateway can be used. It is not only low-cost, but also powerful, simplifying a lot of
work for system integration engineers.
