Oil & Gas Industry Training



The increasing trend towards digital communications within the industrial plant environment has brought in its wake a myriad of problems concerned with interconnectivity and differing standards offered by a wide variety of competing vendors. For the user, it has become progressively more difficult to differentiate between the proffered options.

This workshop, Data Communications and Fieldbus systems, provides an in-depth look at the divisive field of modern analog and digital data communications and Fieldbus systems over copper, fibre-optic, and wireless links. Starting at basic coding and formatting systems, the course progresses through error detection, protocols, RS232, RS485, HART, Modbus, Profibus/Foundation Fieldbus, Ethernet and TCP/IP. Particular attention is paid to the newly established wireless standards. An add-on module is also available covering the re-emerging DNP3 standard specific to the utilities industries.

what this training course will teach you

The course is based on a wealth of experiential knowledge gleaned from the author's experience working within a systems integration company and also feedback from more than 4000 technicians and engineers who have attended the author’s workshops. On successful completion of this workshop delegates will be able to:

  • appreciate the basic principles of data communications and gain an insight into the major technologies used in modern data communication and fieldbus systems
  • understand the essential differences between asynchronous and synchronous transmission
  • apply basic faultfinding techniques covering RS232 up to RS485
  • understand the importance of the ISO OSI model
  • understand the basis of cyclic redundancy
  • fully appreciate the sources of interference noise
  • appreciate the value of HART in both calibration, data collection and diagnostics
  • apply Modbus in a practical manner and make use of troubleshooting techniques
  • differentiate between Modbus and Modbus Plus
  • gain an insight into the essential differences between Asibus and DeviceNet
  • make an informed appraisal of the differences between  Profibus and Foundation Fieldbus
  • understand the basics of Ethernet
  • appreciate the application of Ethernet in the industrial environment
  • understand TCP/IP and its associated protocols
  • differentiate between net and sub-net masking
