ABB REX610 Protection and control functions


Therefore, several of the rules for hardening automation systems apply to these systems as well. From an automation system perspective, protection and control relays are at the bottom of the hierarchy, closest to the actual main processes. It is important to apply the “defense-in-depth” information security concept, whereby each layer in the system is capable of protecting the automation system, and therefore the protection and control relays are part of this concept. The following points should be considered when planning system protection.

– Recognize and familiarize yourself with all parts of the system and the system’s communication links

– Remove all unnecessary communication links from the system

– Rate the safety level of the remaining connections and improve them using applicable methods

– Harden the system by removing or deactivating all unused processes, communication ports, and services

– Check that all applicable parts of the entire system are backed up

– Collect and store backups of system components and keep them up to date

– Remove all unnecessary user accounts

– Define password policies

– Change default passwords and use strong passwords

– Check that strong encryption and authentication is used for links from the substation to higher-level systems

– Separate public (untrusted) from automated (trusted) networks

– Isolate traffic and networks

– Use firewalls and demilitarized zones

– Evaluate systems regularly

– Use malware protection in workstations and keep it up www.cniacs.com to date It is important to utilize defense-in-depth concepts when designing automated system security. Connecting devices directly to the Internet is not recommended without adequate additional security components. Security controls should be used for the different layers and interfaces in the system. In addition to product features, strong security means enabling and using available features and enforcing their use according to company policy. Proper training of personnel accessing and using the system is also required.

Mitsubishi Net IR-S Infrared Flame Detector

Overview

In response to the need for modern monitoring and control systems in thermal power plants, the

Net IR-S infrared flame detector combines the proven IR-S type flame detector, which has been successfully installed in many power plants, with Mitsubishi Electric’s DIASYS Netmation control system.

The result is a flame detector product that can be used as a burner control system.

The Net IR-S has the same sensor unit as the conventional IR-S sensor and can be used with any of the following fuels: fuel oil, coal and natural gas.

In addition, the excellent detection reliability, maintainability and cost effectiveness of the IR-S sensor are maintained.

In addition, the decision circuitry is built as a module of DIASYS Netmation. It is used in conjunction with the upper layers of the Netmation to provide an easy-to-use interface.

The panel of the Net IR-S can be designed as a stand-alone flame detector system independent of the burner control system.

If you replace a conventional flame detector with this new flame detector, you can reuse your existing equipment.

Features

Highly sensitive design

High sensitivity to flame intensity enables stable www.cniacs.com detection of burner flames. Flames are detected through unlit areas.

Extended detection range

With 100 times the dynamic range of conventional products, this sensor enables stable detection of flames from slow burning to high intensity. No sensitivity adjustment of the sensor is required in the field.

Maintenance-free

A ball lens is used to eliminate the need to clean the sensor window during normal boiler operation.

Long Life Sensor

No periodic replacement is required due to the use of long-life infrared semiconductor sensor elements.

Reduced number of panels

The detector unit is compact and utilizes a space-saving design that allows one panel to contain 40 corners.

Reuse of existing boiler facilities

The boiler itself does not need to be worked on when the flame detector is replaced.

Reuse of cables    

There is no need to replace the cable between the sensor and the panel. (When UV type detection is used in an existing system)

Mitsubishi IR-S Infrared Flame Detector

OVERVIEW

The IR-S type infrared flame detector is an excellent high sensitivity type that excels in “detection reliability”, “maintainability” and “economy”.

It supports boiler fuel diversity and low NOx (nitrogen oxide) operation.

By detecting the “average value” and “variation” of the infrared intensity of the burner flame light transmitted to the infrared sensor (semiconductor element) via a light guide (optical fiber), the detector can distinguish between the flame and the light due to the furnace.

The detector distinguishes between flame and infrared light due to the red heat of the furnace wall and detects flame fluctuations in the burner’s ignition zone.

The IR-S type infrared flame detector has low brightness flame detection sensitivity and a wide dynamic range, so it can be used for a variety of fuels such as natural gas, heavy oil, and coal.

Features

High sensitivity design

High sensitivity to flame intensity enables www.cniacs.com stable detection of burner flames. Flame is detected through unlit areas.

Extended detection range

With 100 times the dynamic range of conventional products, this sensor enables stable detection of flames from slow burning to high intensity. No sensitivity adjustment of the sensor is required in the field.

Easy Maintenance

A spherical lens is used to eliminate the need to clean the sensor window during normal boiler operation.

Long Life Sensor

No periodic replacement is required due to the use of long-life infrared semiconductor sensor elements.

Fewer panels

The detector unit is compact and features a space-saving design that allows one panel to cover up to 40 corners.
