Permess: Plant-Wide Error Messaging System

A few years ago ? when the idea of Permess was born ? it was expected to be of large interest to set up an automatically working messaging system, based on the request for high efficiency of production and quality assurance as well as environmental points of view. The increasing existence of communication technologies had been expected, being a good set of tools for the implementation of Permess. Today, many components are commercially available which are useful for a realisation of such systems. In fact, this is the proof of the basic idea being right and important. The real market has made it easier to develop messaging tools as there are very important tools, widely spread and easy to use and adapt to special tasks. The use of instant messaging technologies is even part of general operating systems and is in general use today. Different open software protocols and tools such as Jabber or Java show very useful features and are easy to adapt for their use in messaging tools. PDA and hand-held computers are getting more and more powerful and bring extraordinary possibilities to deliver fault information in a ubiquitous and immediate manner.
