8.3.3 Macintosh Custom Software
The Tescom protocol is provided and written in C. The protocol software can be
easily compiled with custom software for the Macintosh. A demo program is
also provided to ensure proper system operation and provide an example
program using the Tescom protocol software.
8.4 DOS Programs
To run any of the DOS-based programs, type 'C:\TESCOM2\TESCOM' at the
DOS prompt and follow the instructions on the display.
Most subdirectories contain a README.DOC file describing the files in the
directory.
8.4.1 Tune
The program TUNE.EXE provides the user with access to many of the
controller's programmable variables. It also includes a graphics screen for
displaying the setpoint and feedback.
In addition, it includes a function
generator for creating waves (square, sine, triangular or sawtooth) that are
transmitted as setpoints to the controller.
This program provides a powerful means of tuning the ER3000. Details on its
use can be found in the file tune.doc.
8.4.2 Ertalk
The program ERTALK.C is a simple program illustrating the use of four of the
library functions.
It can be used to read or write any of the controller's
programmable variables, as outlined in Section 9, "ER3000 Internal Variables".
8.4.3 Profile
The Profile directory contains a set of programs that will allow users to construct
complete pressure profiles by writing a DOS batch file. Each program will
perform a different profile function (start, ramp, soak or step) and store the
setpoint, feedback and time in a file called data.txt. This file can be imported to
a program such as Excel to plot the profile. The programs and their descriptions
are documented in README.DOC residing in TESCOM2\PROFILE directory.
It should be noted that this method of profiling writes to the ER3000 setpoint
variable, which is different then the embedded profiling capability of the
ER3000. The PROFILE2 program actually downloads pressure profiles into the
ER3000 for embedded pressure profiling.
8.4.4 Profile2
The user may use functions such as: ramp, dwell, step, change variable, loop,
digital in, and digital out to construct the desired profile (refer to Section 3
(ER3000 Model Description) for models with digital in and digital out). The
