Section 5. Overview

The application program is written in CRBasic, which is a programming language
that includes measurement, data processing, and analysis routines and the
standard BASIC instruction set. For simpler applications, Short Cut
(p. 514),
a user-
friendly program generator, can be used to write the progam. For more demanding
programs, use CRBasic Editor
(p. 493).
After measurements are made, data are stored in non-volatile memory. Most
applications do not require that every measurement be recorded. Instead, the
program usually combines several measurements into computational or statistical
summaries, such as averages and standard deviations.
Programs are run by the CR800 in either sequential mode
(p. 514)
or the more
efficient pipeline mode
(p. 509).
In sequential mode, each instruction is executed
sequentially in the order it appears in the program. In pipeline mode, the CR800
determines the order of instruction execution.
5.1.1 Wiring Panel — Overview
In the following figure, the CR800 wiring panel is illustrated. The wiring panel is
the interface to most CR800 functions so studying it is a good way to get
acquainted with the CR800. Functions of the terminals are broken down into the
following categories.
• Analog input
•
Analog output
•
Pulse counting
• Digital I/O input
• Digital I/O output
•
Digital I/O communications
• Dedicated power output terminal
