Note:
There are major differences between the Control Builder tools in different releases of Ovation. Students must enroll in the course that applies to their system. If the plant Ovation system is level 3.1 or higher, the student should enroll in OV200-WIN-3.1.X. If the plant Ovation system is an earlier release, please enroll in OV200-WIN-3.0.X.

Prerequisites
Students must have a good understanding of the Ovation® system architecture
and how database point records are built and maintained in the Ovation Windows-based
system. It is recommended that students attend OV100-WIN prior
to attending this course.
Description
OV200-WIN-3.0.X is designed to provide proficiency in reading Ovation functional control
schemes. Tuning, building and implementing new control
schemes to improve performance are also covered. Both modulating (analog)
and discrete digital control schemes are included in the scope of this course.
Discussions will include the various types of control algorithms available and
how they can be used to create effective control. This course is intended
for people who work with Ovation controllers
to tune and build analog and digital control schemes in a Windows environment.
Course Objectives
Upon successful completion of this course, using the reference material provided,
the student will be able to:

- Demonstrate proficiency in building digital and analog
control
- Design and implement a tracking scheme to meet specific
control requirements
- Recognize the relationship between control schemes
and graphic diagrams
- Implement given control requirements using the Control
Builder
- Evaluate and determine the proper operation of a control
scheme using the tools and methods provided
