Over the past few years, the Industrial IoT (IIoT) has been transformed from a concept into real solutions that focus on business-to-business, device-to-device, and people-to-device connectivity across industrial networks.

The first step to realizing an IIoT application is data collection, and an ever-increasing number of IIoT technologies are now available to collect large amounts of data from monitored OT systems. There are 3 key actions that can help you seamlessly connect your devices, data, and SCADA systems:

• Convert I/O signals to multiple OT protocols: Modbus, EtherNet/IP, Active Tag
• Deliver data to a local SCADA system and database
• Ensure data completeness: supplement data automatically, on demand, or on a schedule

Moxa’s Smart I/O is a gateway that converts I/O signals to multiple OT protocols, and supports the most often-used protocols for retrieving I/O data, including:

• Modbus/TCP
• EtherNet/IP (ioLogik E1200 series)
• Active tags (exceptions are actively pushed to MX-AOPC UA Server)

This helps users easily expand data collection through PLCs and efficiently collect data for SCADA/Database software.

Moxa’s MX-AOPC UA Suite includes MX-AOPC UA Server and Logger, which are based on the OPC UA standard. OPC UA provides a cohesive, secure, and reliable framework for accessing real-time and historical data. MX-AOPC UA Server not only inherits Moxa’s patented active monitoring technology, but also supports Modbus protocol for polling data, providing a secure and reliable gateway that bridges edge devices to a SCADA system. MX-AOPC UA Logger is a client that converts and uploads data logs to a central database. With Moxa’s MX-AOPC UA Suite, users can now instantly receive alarms, view real-time updates, and save historical data, allowing for both timely risk prevention and solid maintenance response.

Everyone has heard the old adage, “garbage in, garbage out,” but the reality is that ensuring the quality and integrity of big data is not easy. A cause for concern is the inevitable unexpected connection interruptions that plague any network, and which could result in data loss and expensive shutdowns of important business processes. Moxa’s smart data acquisition method helps shrink the amount of data that needs to be transmitted and ensure data completeness. After each network connection, MX-AOPC UA Logger will compare historical data stored on the SD cards located in individual Moxa ioLogik 2500 devices with the real-time data it has already stored locally, and then supplements any missing data by requesting that the devices retransmit any lost data. Additionally, users can trigger data supplements at any time, on a specific date, or every day at a specified time to ensure data completeness. This kind of smart data acquisition enhances the quality and integrity of big data, resulting in more accurate analyses.
