Organised by PROFIBUS & PROFINET International UK (PI UK), this free-to-attend training event in Manchester covered many of the key issues involved in the use of advanced network communications in Process and Hybrid Industry applications.
Recently, a new phenomenon has appeared during the search for the causes of network failures. It has been noted data communication issues are becoming more frequent in situations where conventional network analysers do not reveal any weak points.
It was the investigation of shield currents on industrial data communication lines that prompted the usual diagnostic approach to take a completely new turn. It soon became clear that the bus itself was in perfect condition, but was being affected by external influences that are generally referred to as "EMC interference". Further extensive measurements, both in the bonding system and in the shielding connections of bus lines, revealed an association between high leakage currents (mostly of higher frequency) and bus failures.
Phoenix Contact will be profiling their HART to PROFINET multiplexer (pictured) which allows existing HART enabled devices to be connected to a PROFINET network, with little or no disruption to established plant architecture. Additionally we will be previewing our innovative, EX rated device servers and protocol converters.
