Twido Controllers

Schneider Twido Maintenance Course

Course Duration:
3 Days

Documentation:
Twido Controller Training Manual.

Equipment per student:
Twido controller
Programming laptop
Plant simulator

The Twido Maintenance Course has been designed to familiarise Electricians, Technicians and Maintenance Engineers with little or no experience of Schneider Twido systems to the different aspects associated with the operation and maintenance of Twido controllers using the TwidoSoft programming software. This course is intended to give students the background knowledge and practical experience in working on a Twido 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 Twido Controllers.

• To recognise and understand the hardware associated with Twido controllers.

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

• To be able to open and understand the project folder structure of the Twido PLC program and to have the confidence to implement minor changes to the ladder program and register values.

• Understanding the use and operation of Twido ladder instructions set.

• To be able to use the TwidoSoft programming software to connect online to monitor (animate) and be able to use the search facilities to chase through the program to determine problems on plant.

• To understand the operation and terminology of Twido Ethernet communication links and understand how the Ethernet connection is used to configure an OTB I/O island.

• To be able to locate and replace faulty modules by understanding and using the cpu LED’s and system bits and words  within the controller when an error is present.

• To be able to transfer a copy of the Twido controllers program to create a backup. To be able to transfer a program back into the controller from a backup copy.
