Industrial automation systems can be quite versatile - take them out of the factory and beside a rail track and even Britain’s or Germany’s infamous trains might run like an oiled automation line. In order to prove this hypothesis, a transportation company and an automation expert join forces.

A week ago, security researcher Rubén Santamarta publicly announced details of multiple vulnerabilities affecting the Schneider Electric Quantum PLC Ethernet Module, and coordinated his findings with ICS-CERT. The Quantum Ethernet Module is prone to an authentication-bypass vulnerability.

Today, control units for industrial automation need to be modular in order to keep cost and integration effort at a reasonable level. Since many of those applications require components (i.e software and hardware) from different vendors, certification and licensing issues arise. Bundles or system platforms may ease those pains.

Every IT specialist worth his salt wouldn’t connect a critical SCADA system to the Internet without the strictest of precautions. It seems that people like that don’t work for critical US infrastructure facilities.

A manufacturer’s declaration is asked by the IO-Link Consortium for all IO-Link Masters and Devices in order to get IO-Link conformity. Therefore, test equipment is neccessary which allows checking all relevant parameters. A major part is EMC conformity.

ZigBee technology has been in use in building automation for a few years now, and finally the alliance agreed on a standard, based on BACnet.

Many industrial applications require long-term availability of their components. While this is comparatively easy when it's about mechanics, industrial computers depend on the availability of processors, memory, controller-ICs and similar rapidly-changing parts. Usually, the choice is between using "mature"
technology and expensive deals with providers
specialized in 'banking' components. Maybe there's a different approach?

Specialists in fieldbus technologies don’t usually give anything away for free, neither as in free beer nor as in free speech, to quote Richard Stallman. Since manufacturers often even charge extra for supplying the (standard) software driver necessary to operate the devices they sell, any exception of that policy is remarkable.

There are various obstacles for a stronger perpetration of wireless networks in the process industry. Since RF communication would simplify life in many ways, there are efforts being made to overcome them. While a mesh architecture is a good way to get optimum coverage, common solutions are difficult to integrate in automation infrastructures.

Many fieldbus systems originate in the last century, including the installed hardware basis. Slowly, the architectures are being enhanced to make use of modern technologies. As an example, PCI Express allows for transparent implementation of different interface techniques, including Profibus.
