|The MX-AOPC UA Suite includes the MX-AOPC UA Server, Viewer*, and Logger*, which are all based on the OPC UA (Unified Architecture) standard. OPC UA is the next generation OPC standard (IEC 62541), which provides a cohesive, secure, and reliable framework for accessing real-time and historical data. The MX-AOPC UA Server not only inherits Moxa’s patented active monitoring technology, but also supports Modbus protocol for polling data, to provide a secure and reliable gateway bridging edge devices to the SCADA system.
The MXAOPC UA Viewer is an OPC UA client that allows users to easily view tag values and server statuses. The MX-AOPC UA Logger is another handy client for converting and uploading data logs to the central database. With Moxa’s MX-AOPC UA Suite, users can now instantly receive alarms, real-time updates, and save historical data, allowing for both timely risk prevention and solid maintenance response.
|Moxa has pioneered the concept of “active type” OPC software in the automation industry. The patented MX-AOPC UA Server offers both polling and non-polling architectures alongside the standard OPC UA protocol, giving users the alternative of pull or push-based communication from Moxa’s devices. With push technology, I/O status is updated to the MX-AOPC UA Server only when there is an I/O status change, a pre-configured interval is reached, or when a request is issued by a user. This application of push technology cuts metadata overhead, resulting in faster I/O response times and more accurate data collection than traditional pull-based architectures. With Moxa’s “active technology” advantage, users can now instantly receive alarms and real time updates, allowing for timely risk response.|
