The DA-720-DPP series computers are x86 platforms with 14 gigabit Ethernet ports, 2 isolated RS-232/422/485 serial ports, USB, VGA, and 2 PCIe ports for expansion modules. The DA-720-DPP comes in a standard 19-inch 2U rack-mountable case with a robust design ideal for specialized industrial automation applications, including power substations, railway, factory, and building automation.

With IEC-61850-3 and IEEE 1613 compliance, the DA-720-DPP is sure to deliver stable and reliable system operation for power applications. The DA-720-DPP also complies with the IEC 60255 standards which cover the protection of electrical relays in a smart substation. IEC 60255 is one of the most widely used standards for testing relays and protection equipment, and compliance with the standard ensures that the DA-720-DPP will work reliably and seamlessly with IEDs as part of a robust substation automation system. 

EN 50121-4 compliance confirms that the DA-720-DPP can deliver stable and reliable system operations in rail applications. In station ISCS (Integrated Supervisory Control System) and wayside control and monitoring systems, a powerful front-end processor is needed for controlling the local SCADA and traction power relay house. The expandable serial interfaces and 14 gigabit Ethernet ports enable the integration of station subsystems, including AFC, PAS, PSD, and FAS, on a single platform. For wayside applications, you can also integrate disaster prevention, traction power, and signaling and safety systems to provide an integrated view of your smart rail setup.

The DA-720-DPP comes with one of two different CPU options, and basic models that allow system designers to install the mSATA, RAM, and operating system according to their specific requirements. Such  a wide choice of options is particularly welcome when it comes to designing customized industrial solutions. 

The DA-720-DPP comes with 2 PCIe ports for expansion modules, including an 8-port RS-232/422/485 module, as well as 4-port and 8-port 10/100/1000 Mbps LAN modules. The DA-720-DPP computers can support up to 22 gigabit LAN ports plus 10 serial ports, or 14 gigabit LAN ports and 18 serial ports, making the DA-720-DPP an ideal solution for a wide range of industrial automation applications.

Smart Recovery Function

The DA-720-DPP’s Smart Recovery function minimizes downtime by making it easy to recover from operating system crashes. Engineers who are experts in a particular vertical market may not have enough computer domain knowledge to know how to fix operating system problems. Moxa Smart Recovery™ is an automated BIOS-level software recovery system that allows engineers to automatically trigger OS recovery to minimize downtime. 

Proactive Monitoring Function

Moxa Proactive Monitoring is a small-footprint, resource-friendly, easy-to-use utility that allows users to track a number of system parameters. Users can view the current parameter values for these key parts by simply clicking on the icons corresponding to the parameters in the user interface. User-defined key part indicators (KPIs) are used to monitor the computer’s key parts. Visible and/or audio alerts are triggered automatically via relay and SNMP traps when these KPIs exceed their preset threshold values, making it extremely convenient for operators to avoid system downtime by setting up predictive maintenance tasks well in advance.

Using MMS and SNMP to Integrate IT Management for Substation Automation

Using MMS and SNMP to Integrate IT Management for Substation AutomationThe 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
