The ease of setting up a PROFINET installation can lead people into a false sense of security. PROFINET is a diagnostic-rich protocol allowing device-related diagnostics to be shown on SCADA / HMI screens, but this is clearly dependent on the communication network working correctly. The consequences of network failure cannot be underestimated and unless the network is designed for network-level support and initially validated at a communications level, then faults in the future will be difficult to diagnose.

Control Specialists Ltd are a PROFIBUS and PROFINET International Competency Centre (PICC) which gives us a manufacturer-independent aspect and expertise in these widely-used technologies. Peter Thomas of Control Specialists Ltd is the Technical Officer of PI UK.

Using Certified PROFINET Engineers and the monitoring & diagnostic tools of our partner Procentec , Control Specialists Ltd will ensure that the fundamentals such as topology, measuring points, device cycle times, net loading, 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 the experience of using network-level diagnostic monitoring and auditing tools to assist us with the support of existing PROFINET networks and combine this with our 20+ years of experience in supporting automated control systems. You may also be interested in looking at our EMC support services which are very relevant to PROFINET networks.

We are also a PROFIBUS & PROFINET International Training Centre (PITC) and are able to provide practical training on the installation, commissioning and support of PROFINET networks at your premises. Peter Thomas of Control Specialists Ltd is the Chairman of the PROFIBUS and PROFINET International Training Centres working group.

Control Specialists Ltd play an active role within PROFIBUS and PROFINET International (PI) and regularly give technical presentations at seminars run by PI UK.
