PROFIBUS is an established fieldbus used extensively in a wide variety of industrial automation applications. Despite this, many PROFIBUS networks operate with underlying issues as a result of decisions made during the design phase of the installation. These issues often remain undetected until changes are made to the network, often many years later, and then start to cause problems that can be difficult to diagnose.

Using Certified PROFIBUS Designers, Certified PROFIBUS Engineers and the monitoring and diagnostic tools of our partner, Indu-Sol GmbH, Control Specialists Ltd can provide assistance with design and commissioning of new installations or the support of existing ones. Our design team will ensure that the fundamentals such as topology, measuring points, cable lengths, EMC requirements etc. are established at the design phase and then formally validated to establish conformance to the design as well as ensuring that the network is operating within defined limits. We have several years of experience in supporting and fault-finding on PROFIBUS networks where our wider experience in automation control systems often helps us resolves issues where others have failed. You may also be interested in looking at our EMC support services which are very relevant to PROFIBUS networks.

In conjunction with our partner Verwer Training & Consultancy Ltd, a PROFIBUS & PROFINET International Training Centre (PITC), we are able to provide practical training on the installation, commissioning and support of PROFIBUS networks at your premises and also at the Application, Training and Engineering Centre of Endress+Hauser in Manchester.

We have the experience of using network-level diagnostic monitoring and auditing tools to assist us with the support of existing PROFIBUS networks.
