Data Communication &
Fieldbus System

Over the last couple of years, instrumentation has come on in leaps and bounds. It is just as important to note the data communication has not been left behind, and has rightfully kept pace with all the requirements of the modern plant. There is an increased tendency towards better data communication (especially in the industrial environment), and the aim of this GLOMACS Data Communication & Fieldbus System training seminar is to take all the mysticism out of the data communication systems, in existing (and future) networks.

This GLOMACS Data Communication & Fieldbus System training seminar covers all aspects of data communication, starting from an overview perspective and then delves individually into all the major aspects that are considered important to current users. Special attention is also given to the hybridized systems (i.e. HART) as well as the all-important fieldbus options that currently play such an important role in communicating with field devices. This GLOMACS training seminar is presented in a manner which is easy to understand and grasp, even for novices and those new to the field of data communication and fieldbus, as well as those that wish to improve / refresh their current knowledge.

This GLOMACS training seminar will highlight:

• Data communication and basic principles
• Communication standards
• Communication media
• Communication protocols
• Fieldbus and how it ties in with the modern instrumentation

• Understand the basics of cabling utilized with data communication and fieldbus systems
• Have a full understanding of industrial protocols
• Distinguish between physical communication standards (232, 423, 422, 485)
• Examine the various aspects of the OSI model
• Compare, contrast and debates network architecture and hardware pertaining to data communication and fieldbus systems

Participants will be taken from basics, and built up in their ability to deal with all the major types of data communication and fieldbus systems. The most important components of the work are covered in a theoretical manner, but the instructor will also ensure that delegates are individually assessed on a regular basis. This GLOMACS Data Communication & Fieldbus System training seminar will make use of pre-and post-seminar tests, individual and group-based exercises, open discussions and make use of proven adult learning methodologies and facilitation techniques. The whole focus is on the transfer of vital data. The sharing of information, between delegates and participants, is encouraged.

Delegates will return to their place of work, equipped with the skills and knowledge required to maximize the performance of the current data communication networks, and the competency skills to guide decision-makers in the planning and implementation of future data communication and fieldbus strategies.

The organizational impact would include:

• Having people with comprehensive knowledge pertaining to data communication and fieldbus systems
• Having staff with knowledge that has been built up on a solid foundation
• Having staff members that can effectively communicate about the subject matter with their peers
• Having staff that can identify possible problems that may occur, and what the solutions might need to be
• Having people with an understanding of all the hardware associated with data communication and fieldbus systems
• Having people who can assist in the specification of data communication and fieldbus additions to current and existing networks

Participants will gain knowledge, enhance / hone their skills and learn to apply themselves fully in their workplace. Improved knowledge often equates to better career prospects within the organization, and recognition that the participant can play a more meaningful leadership role in their field of expertise.

Personal impact would include:

• Building up their own levels of self-confidence in the subject matter
• Communicating effectively with their peers, operators, management and supervisory staff
• Enhancing the knowledge and understanding of the subject matter
• Giving them the peace of mind to participate in meaningful discussion and analysis pertaining to data communication and fieldbus systems
• Reduce the amount of time in problem solving, because of better understanding of the subject matter. This should equate to improved time management
• The ability to show the organization that they are a valuable team member, and that they can develop within their current careers

This GLOMACS Data Communication & Fieldbus System training seminar would be particularly aimed at people who are involved either in the maintenance and installation of data communication and fieldbus equipment, or those that actively take part in the assessment, selection and purchasing of these devices. But, it is not specifically aimed only at these individuals, but also to cater for the needs of all levels of personnel, regardless of their working background, who have an interest in the field of data communication and fieldbus systems.

In this sense, this GLOMACS training seminar is suitable to a wide range of professionals but will greatly benefit:

• Instrumentation Personnel
• Personnel involved in data communication and networked topologies
• Artisans from other fields, who may assist, or be interested in data communication and fieldbus systems
• Financial People involved in the purchasing of data communication and fieldbus equipment
• Commissioning Engineers
• Process Control Engineers
• Health and Safety Representatives
• Administration Staff
• Foremen and Supervisors who oversee staff performing functions on the data communication and fieldbus equipment
• Cost-controllers
• Lower Middle and Top Management
• Engineers from Non-instrumentation Disciplines
