Overview

The DA-662A RISC-based, ready-to-run embedded computers are designed for industrial data acquisition applications. The computers have 8 to 16 RS-232/422/485 serial ports, 4 Ethernet ports, and 2 USB 2.0 ports, all based on the MoxaMacro communication processor. In addition, the DA-662A-I-8/16-LX’s serial ports come with high level interference protection. The housing is a standard 1U, 19-inch wide rack-mounted rugged enclosure. The robust, rack-mountable mechanism design provides the hardened protection needed for industrial environment applications, and makes it easy for users to install the DA-662A computers on a standard 19-inch rackmount. The DA-662A computers are ideal for applications that require a distributed embedded technology, such as SCADA systems, plant floor automation, and power electricity monitoring applications.

Application Note

Efficient IIoT Data Processing with High I/O Density Computers

With more and more companies implementing IIoT applications, the demand to connect hundreds or thousands of devices to industrial automation systems has increased dramatically. The DA-720, a high-performance industrial-grade x86 platform, is ideal for such applications. It is based on the lntel® 6th Gen Skylake processor and provides a high density of gigabit Ethernet and serial ports in a 19-inch 2U rack-mountable case, making it an ideal choice for IIoT applications in industrial automation systems.

How to Get the Best Out of the IIoT with Predictive Maintenance

The Industrial Internet of Things (IIoT) is shaping the way industrial applications are designed and implemented today. The IIoT is ushering in a new era of operational efficiency, information transparency, and economic growth. Innovative ideas on how to collect data, how to transform data, and how to use the data to increase efficiency and reduce costs are sprouting up all around us. The IIoT has bridged the gap between the physical and digital worlds and has created one combined space that provides limitless possibilities. In addition, the relentless pursuit of excellence in the IIoT world has renewed an interest in predictive maintenance solutions that ensure higher equipment reliability and system uptime.......more

Intelligent Automation for the Maintenance and Recovery of Software Platforms

Automation advances in industrial processes increasingly involve using industrial PCs for the control and monitoring of every sort of machinery and process. Yet as industrial PCs penetrate ever further into the automation stack, the problem of data loss and system corruption becomes a critical consideration both for the security issues raised as well as overall system availability. In this white paper we examine the software and hardware features that constitute an effective, fully automated, BIOS initiated, block-level software recovery solution that can be used across any industrial environment, whether following emergency crashes or for automated preventive maintenance......more

Making Smart Substations Even Smarter: Enhancing Substation Reliability, Availability, and Maintainability

This paper sketches out a few of the more important concerns that electricity suppliers should account for when planning substation upgrades. The focus is on how best to increase the reliability, availability, and maintainability of power substation automation networks within the context of the IEC 61850 vision, to give electricity suppliers a clear idea of the design procedures, device tolerances, and hardware and software features they should expect from the engineers and manufacturers who design and build their networking and computing devices.......more

Using MMS and SNMP to Integrate IT Management for Substation Automation

The devices that electrical substation automation systems are built from depend on highly precise, time-critical communications. Substation thus often use highly specialized monitoring systems to tackle this problem, but can approach it using different technologies. The most up-to-date, “smart” substations use the Manufacturing Messaging Specification (MMS) for communications among IEC 61850 intelligent electronic devices (IEDs), allowing SCADA to monitor and control IED states as well as process switchgear and transformer data directly. However, IT networking devices have been increasingly applied in IEC 61850 systems, and this equipment communicates using SNMP. Consequently, in the modern substation automation industry it’s clear that, for the time being, SNMP and MMS will continue to exist side-by-side. For designers and integrators of electrical substation equipment, bringing both MMS and SNMP support to IT equipment is an ideal, one-size fits-all alternative that allows for the greatest flexibility and adaptability around........more
