Communication is a vehicle for progress and way of connecting events and processes, how often described in different forms. In social life, communication allows mutual understanding the people speaking different languages, professing various religions, taking care of different habits, and even more, uniting the nations in groups of common interests. A bit like programmable automation systems. Communications integrates local solutions, although many companies producing PLC use their own "languages" that hinder the exchange of data with products from third party suppliers. Procedures for information exchange in industrial networks are very similar to each other, but practical solutions are, however, so different that sometimes it is a veritable "Tower of Babel", so customers to benefit from competitive solutions are forced to complex changes in plant automation. TECOMAT PLC controllers solve the problems in exchange of information among systems with different standards for data transmission.
