For any industrial solution, the question arises as to where and how a new technology can operate cost-efficiently. There are a lot of applications in which wireless transmission gives users new tools to introduce completely new processes that were inconceivable in the past due to the limitations of electric line solutions. One example for such applications is the use of portable operator terminals with wireless interfaces, which can considerably simplify maintenance and commissioning tasks.

Software is an integral part of modern control and automation systems. Information technologies merge with automation and control systems. This process is unavoidable and affects the whole industry. A huge number of techniques and possible new Web applications for automation bring about new possibilities and requirements for control systems interoperability. Now we are facing a market of new smart transducers and actuators that can be accessed by wired or wireless media locally or through the Internet.

Successfully entering the next generation of industrial automation platforms is all about enabling technologies that allow a facility to become world-class. Automation has adopted the use of standard, well-understood, non-proprietary technologies like Ethernet, XML and cellular for machine-to-machine (M2M) related activities. These are networking technologies that facilitate communications. With everything based on Internet Protocol (IP) and its associated interfaces, underlying technology lets manufacturers avoid proprietary problems. Plus, getting IP on the plant floor is possible without necessarily replacing the equipment currently in place.

Flexible automated process is possible when manufacturers match their needs with the technology available. Collaboration needs to improve to avoid the mentality of completely designing systems in-house, which only leads to major mismatches and takes away flexibility. While legacy systems are still an obstacle, the next-generation facility needs to focus more on legacy support. It is not effective to rip and replace equipment with every new development. Networking and messaging are keys to integrating automation and legacy systems. They add flexibility and allow to make equipment more adaptable.

The human machine interface (HMI) functionality is also changing dramatically, fixed panels with specialized displays for each aspect must continue moving to integrated open access that can allow back office and offsite monitoring.

Manufacturers also need to look outside their four walls and become interoperable with key suppliers and customers, because it does not matter how efficiently a company produces finished product if its suppliers deliver the wrong component parts or raw materials, or if it takes six weeks to coordinate a customer change order with your key suppliers. The key obstacles here continue to be a lack of standards, security and finding a scalable framework for interoperability. The tremendous variety of technology standards makes technical interoperability difficult, time consuming and costly.
