GEM 80 Maintenance training using DOS

GEM 80 Maintenance Course Using a DOS Programmer

Course Duration:
4 Days

Documentation:
GEM 80 Maintenance Training Manual.

Equipment per student:
GEM 80 controller
DOS Programming laptop
Plant simulator

The GEM 80 Maintenance Course has been designed to familiarise Electricians, Technicians and Maintenance Engineers with little or no experience of GEM 80 systems to the different aspects associated with the operation and maintenance of GEM 80 controllers and the system programmer emulator DOS software. This course is intended to give students the background knowledge and practical experience in working on a GEM 80 system so that they have a good understanding of the system and have the ability to make small edits and make changes to program parameters.

Where possible, application specific exercises, actual drawings and plant programs will be used to allow the students to gain the greatest possible benefit from the course.

Objectives

• To introduce students to the concepts, terminology and operation of GEM 80 Controllers.

• To recognise and understand the hardware associated with GEM 80 controllers.

• To recognise and understand what the system LED’s and Watchdog LED’s indicate.

• To be able to open and understand the structure of the GEM 80 program using a DOS programming package and to have the confidence to implement minor changes to the ladder program and parameters.

• Understanding the use and operation of GEM 80 standard instructions and GEM 80 special functions.

• To be able to use the DOS programming software to connect online to monitor and be able to use the search and cross reference facilities to chase through the program to determine problems on plant.

• To understand the operation and terminology of GEM 80 serial communication links.

• To be able to locate and replace faulty modules by understanding and using the system error message when an error is present.

• To be able to create a backup copy of the GEM 80 controllers program. To be able to restore a program back into the controller from a backup copy.
