INDUSTRIAL NETWORK SUPPORT
Whether you are wanting assistance with the design of your industrial networks or need support in resolving a problem, we can help you.
Fieldbus technology, and more recently Ethernet-based communications, are frequently used to facilitate communications between the main components of an automated control system. PROFIBUS has been around since the early 90’s and continues to be the dominant fieldbus the UK. PROFINET, is now appearing in new installations and is fast becoming the industrial Ethernet network of choice for 21st-century automation systems. IO-Link enhances this trend by allowing the Ethernet-based networks to reach the sensor and actuator level using conventional 3-wire cabling. AS-i has other benefits and continues to be used in manufacturing industries.
PROFIBUS and PROFINET are rich in diagnostics that allow devices to report faults and event information to a higher level system like a PLC. However, this is only possible if the underlying network infrastructure has been correctly designed and is operating correctly. It is often the case that many faults can be traced back to design-related issues that can be difficult to resolve. Control Specialists can help you with this and can provide site-based training on PROFIBUS, PROFINET, IO-Link and AS-I networks.
We are active members of the UK PROFIBUS and PROFINET Regional Association and regularly give presentations on their behalf. We also work closely with PROFIBUS and PROFINET International, the vendor-independent organisation responsible for development, certification, marketing and training of the two technologies. As well as having our own Certified PROFIBUS and Certified PROFINET Installers and Engineers, we have access to the experience of our partner Indu-Sol, manufacturers of diagnostic and monitoring tools for industrial networks.
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 (Electro-Magnetic Compatibility) 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.

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.
Using Certified PROFINET Engineers and the monitoring & diagnostic tools of our partner Indu-Sol GmbH, 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 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 (Electro-Magnetic Compatibility) support services which are very relevant to PROFINET networks.

Widely recognised as a solution for connecting field-level devices like sensors and actuators to a higher level system like PROFIBUS or PROFINET, AS-I (Actuator Sensor-interface) is now considered as an established solution for systems that would have previously used conventional on/off switching sensors and actuators.
Using our experience in automation and control and industrial networks, together with the tools of our partner Indu-Sol GmbH, Control Specialists are able to provide site-based support of AS-i installations. Additionally, in conjunction with our partner Verwer Training and Consultancy Ltd, we can also improve the skills of your own support team by providing practical training on the installation, commissioning and support of AS-i installations at your premises.CSL - AS-i and IO-Link Support - V1.0
A relatively new field-level network solution, yet widely supported by manufacturers such as Siemens, Pepperl+Fuchs, Wago, IFM, Turck and Banner, IO-LINK is rapidly becoming the interface of choice for users wishing to get more flexibility from their manufacturing process without the need for expensive rewiring.
Supported by PROFIBUS and PROFINET International, IO-Link should not be considered as a replacement for AS-i but as a parallel solution for connecting a wider range of devices capable of being parameterised during run time and also providing the higher level systems with diagnostic information about the device. IO-Link is the natural choice for those industries wishing to take an Industrie 4.0 path in the development of their manufacturing processes.
As a member of PROFIBUS and PROFINET International (PI), Control Specialists are also a member of the IO-LINK Organisation and have the tools to assist you in supporting this technology as well as being able to offer advice of how to implement it within your existing system. As a member of the UK PROFIBUS and PROFINET group, Control Specialists regularly give presentations on IO-Link.

EMC (Electromagnetic Compatibility) and Protective Earth (PE) issues are acknowledged as being the cause of a significant number of problems on fieldbuses and Industrial networks like PROFIBUS and PROFINET. Over the years, the risk of sporadic failures in electronic systems due to electromagnetic interference has risen sharply. This is primarily a result of an increase in the of the number and energy of disturbance sources (frequency invertors, high-powered drives) and an increase in the number and sensitivity of potential victims (microprocessor-controlled, high-transmission rate devices. Some interesting facts to consider are:
• About 95% of all EMC-related effort (projects, work, money) is just preventative, i.e. complying to applicable standards. Only 5% relates to actual interference / root- cause and identification / solving.
• Suitable cost-effective measures require an understanding of the underlying physical principles.
• The distinction between shielding inside housings (printed circuit boards) and outside (housings and cables) is very important.
• In order to avoid losing track, it is important to focus on the relevant culprits, types of coupling, and victims.
• Many apparent EMC 'field' problems turn out to be direct galvanic in nature (via a wire).
• 90% of all EMC disturbances are caused by errors in the grounding system (functional earth) and are not real EMC 'field' problems.
• 80% of the final EMC (compatibility) of an automation system's is determined by the quality of the functional bonding system (FE).
Using the EMC tools of our partner Indu-Sol GmbH, we are able to provide site-based support to check the effectiveness of your earthling from an EMC point of view.CSL - EMC Support - V1.0
