Basics This chapter describes the system structure of the terminal and its basic functions.
There is also an explanation of the general principles, object parameters and joint
functions applicable in the terminal.
Method for programming a project
The graphical structure of the application in the terminal constitutes a well-arranged
monitoring tool for the operator. It is important to organize the application well and to
consider which functions are necessary. Start with the overall view, and then work down
to the detailed level. When a project is programmed you start with the functions in your
application. Each function becomes one or more blocks, depending on the complexity
of the function. A project can contain both graphic and text blocks, and each block can
contain static and dynamic objects. The blocks should be arranged in hierarchies to
achieve a structured application, and to simplify work procedures for the machine
operator. The application can also be organized as sequence controls.
The application can be tested in full or in part prior to startup.
