1. Aims & Objectives Automation and control system networks operate in a different environment and have different performance requirements to office and IT networks. For example, factory automation or plant control systems are quite often installed in environments where interference from electrical equipment is present. Mechanical vibration, physical impact and exposure to corroding chemicals are also common hazards. Cable, connectors and other network components must be robust and protected against such factors. The requirements on network performance and reliability are also much more challenging because the automation and control systems must operate for long periods without any failure, disruption of communications or delays. For this reason, it is essential that industrial network installations are designed correctly and installed by suitably trained and qualified people. This course aims to provide the theoretical knowledge and practical competence to layout, install, test and maintain PROFNET networks in an industrial environment. The Course is suitable for those with no previous experience of networking or digital communications. However, even experienced technicians can gain significantly from taking this course. The course provides a first stage of training course for those who are involved with the installation, commissioning and ongoing maintenance of PROFINET systems. The course provides an introduction to PROFINET terminology, operation and characteristics. It aims to provide a basic understanding of the problems that can occur in high speed digital communication systems, their causes and solutions. The various rules and guidelines for PROFINET network layout and installation are covered and practical techniques for implementing these are explored in a hands-on and practical way The course teaches how to make-up and test common types of cable and connectors. The common types of fibre-optic cables are also covered, but fibre splicing and testing is outside the scope of the course. Finally the formal installation qualification of a PROFINET network is discussed.



2. Learning Outcomes The following learning outcomes specify what candidates will know or be able to do as a result of successfully completing the training course. The learning outcomes consists of a reference number, description and assessment mode. There are three kind of assessment modes: theory (T), practical (P) and demonstration/class exercise (C). The learning outcomes are grouped in two types of outcomes; supporting and task-oriented. Every paragraph in this chapter contains a group of learning outcomes. The supporting learning outcomes support the task-oriented learning outcomes and are about concept discrimination, factual information and process explanation.

4. Instructors The instructor(s) must have passed the Certified PROFINET Network Engineer Course as a minimum and must be registered with PI.

5. Training and assessment methods The training should cover the topics listed in the content specification below and must cover the learning outcomes. An example slide-set in English is provided by PI as a guideline. The delivery may be customized and formatted to suit the requirements of the instructor and the needs of the candidates. The training must include a significant practical element in which the candidates can apply the theoretical concepts by testing a small network and debugging pre-made scenarios. It is a good idea to include a short tutorial session in which revision/practice questions are answered and checked with the aid of the instructor. The tutorial questions should generally be open-ended to promote discussion and explore any weaknesses or misunderstandings that the candidate(s) may have.

6. Typical Practical Work

• Building a PROFINET cable.

• Testing a PROFINET cable for common faults.

• Setting / Clearing a PROFINET device name.

7. Training Equipment The typical training equipment is given as a guide. Each PITC can decide on the configuration of the equipment so long as the syllabus for the course is covered and the learning outcomes achieved. Example set-up: Engineering tool, GSD Viewer, (IO Supervisor), IO Controller, 4 IO Devices, 1 monitoring switch, Wireshark, cables and connectors, stripping tool, cable tester. It’s suggested that during CPNI training the participants will also have a chance to see in practice the difference between cable tester and cable certifier. Devices from at least 2 different manufacturers shall be included. Devices and components from any supplier can be used (connectors, cables, passive devices). Recommendation: at least 2 different suppliers should be included in the equipment. No more than two students should share a training kit.



8. Assessment Scheme The assessment is a combination of practical and theory examinations. Candidates must score a minimum of 70% in each component to pass the course. Practical Test (Duration 45 minutes) The candidate will be examined according to the learning outcomes specified in sections 2.3 and 2.6 of this document. Theory Test: (Duration 45 minutes) The candidate will be examined according to the learning outcomes specified in chapter two of this document.
