Korenix is pleased to release the brand new performance-optimized JetBox 5300-w Industrial embedded computer Linux with -40 to 80? wide operating temperature for front-end industrial control deployments. The RISC-based computer with low power consumption brings flexibility and reliability to the industrial networking market through its rich interface, featuring 2 LAN ports, 2 USB ports, 2 RS232/422/485 and 2 RS232 serial ports. In addition, the compact JetBox 5300-w carries 4 DI & 4 DO channels allowing users to integrate alarms, indicators, and sensors into their complex networking system.

Main features of JetBox 5300-w are:

RISC CPU low power consumption

-40~80? operating temp, fan-less design

Linux programming

Linux customized configuration auto-run via SD card

4-port serial: TCP server mode

Digital I/O controller: 4 DI & 4 DO, DIO scheduling

SNMP control

Modbus gateway (optional)

The JetBox 5300-w supports the Korenix Auto-Run customization setting on SD card, POE Switch which allows users to configure their own Linux commands once the system is booted. By storing the customized data onto the SD card, software engineers can automatically run specific configurations or run specific applications in the JetBox 5300-w embedded computer making the industrial network management easier and more flexible.

Besides, users can benefit from the optional Modbus Gateway function for Modbus applications by enabling serial Modbus RTU devices to communicate with Modbus TCP devices.

In addition to its advanced software features, the fan-less JetBox 5300-w with redundant dual power inputs and -40 to 80? wide operating temperature range provides reliable and secure data management in harsh environmental conditions, becoming the perfect solution for open-pit mines, railcars, railways, public utilities etc

This is a VERY impromptu RS-485 Modbus network formed by five process controllers acting as Modbus slaves and a personal computer acting as the Modbus master. Configuration software is used to access parameters in the networked controllers using Modbus data packets to shuttle information back and forth between the controllers and the master computer.

Uninterruptible power supplies (UPS) are sophisticated, microprocessor-controlled systems, capable of providing a range of alarm notifications and real-time monitoring information at local, network and remote site locations.

This is important because it offers peace of mind and negates the need for ‘warden-type’ manual inspection of power protection equipment. However, monitoring for alarm conditions is required. The beauty of today’s UPS equipment is that it can now be carried out at one location, either centrally in-house or off-site at a specialist UPS monitoring provider. Many leading power protection manufacturers, such as Riello UPS, provide this type of service. It often means an engineer can be on-site and have equipment repaired, checked and running before the client is even aware of a problem.

The decision not to outsource uninterruptible power supply monitoring must be reinforced by the provision of dedicated monitoring personnel in-house whose responsibility it is to monitor and respond to UPS alarms. Failure to act in a timely and appropriate manner will significantly reduce system resilience. Typical examples include failure to notice that a UPS is operating in bypass mode or that there is a failed battery in a battery string (note: a UPS battery string is only as strong as its weakest battery).

The advent of Html capability in the software arena has enabled modern UPS manufacturers to integrate sophisticated onsite and remote monitoring capability within their hardware. In fact, modern systems enable remote 24/7 monitoring (either by the client or at the manufacturer’s facility) of all critical UPS, generator, air-conditioning and fire suppression equipment. As well as alerting system managers to problems as they arise, integration of monitoring functions into existing infrastructures gives businesses valuable early warning of impending power and other equipment failures that actively increases profitable uptime.

Most UPS are available with software packages that monitor mains voltage, UPS load and battery charge as standard, as well as proprietary monitoring and control software, which allows remote interrogation of UPS logs and operating parameters to help diagnose alarms and faults. When instructed to do so, UPS software can remotely perform automated and controlled shutdown of valuable equipment – ensuring hardware protection while freeing personnel for other tasks during power continuity incidents.

Types of alarms include:

Audible Alarms: audible signals are generated from within the UPS or a connected remote status panel and may be coded, using varying lengths of sound, to indicate specific alarm conditions. Audible alarm signals will remain ‘on’ until the condition is rectified or the alarm is acknowledged and silenced.

Visual Alarms: light Emitting Diodes (LEDs) provide a basic form of visual alarm notification. They may be single or multi-coloured and indicate the status of the UPS by employing one of three modes: on, flashing or off.

Some UPS utilise Liquid Crystal Display (LCD) with push-button controls to provide a slightly higher level of visual alarm capability. In this case, the user can scroll through a menu of information (measurements and logs).

The most sophisticated level of visual display is a full front-panel graphic-type, which typically consists of multi-character back-lit lines that display information in alpha, numeric and symbolic formats, either as text, alarm codes, graphics or a combination thereof.

Remote communication can utilise one of several protocols to provide data-exchange between an application and its UPS: serial connection (including RS-232), Simple Network Management Protocol (SNMP), MODBUS/JBUS or Profibus.

A range of UPS monitoring packages are available from UPS suppliers – from simple installation software designed to run on laptops, PCs and PDAs to more sophisticated monitoring and control software that runs on an enterprise server (whether Microsoft Windows, UNIX, Mac, HP and many others) and provides a host of information from UPS operating conditions to WAP availability.

There are two common approaches to monitoring and control by uninterruptible power supply manufacturers: centralised and decentralised. Centralised is where a specified server is used to control the orderly shutdown of the mixed platform network. Decentralised is where each individual server or PC runs its own copy of the monitoring software and controls its own shutdown procedure. The centralised approach is the most straightforward and least expensive to install but it can introduce a single-point-of-failure into the system. Should the control server hang and fail to shutdown the rest of the routine will be disrupted leading to potential data loss and a system-wide crash. With the decentralised approach, if one server or PC fails to shut down, the problem is isolated, thus achieving a higher level of system resilience.

The human instinct upon hearing or seeing an alarm is often to ignore it but planning how to monitor uninterruptible power supplies and associated alarm signals, and conceptualising appropriate responses, is an important aspect of a power continuity plan. If you want to go into it in more detail, there is a whole chapter devoted to it in The Power Protection Guide.
