6.0 OPERATION
The ANAFAZE 8 PID is operated using the communications interface according to the
commands sent from the host computer. ANAFAZE provides a standard software
package for IBM and compatible computers -- ANASOFT-PID. Alternatively a custom
program can be written according to the guidelines in 6.2
6.1 ANASOFT-PID
ANASOFT-PID is a menu driven program that operates up to 16 ANAFAZE 8 PID
controllers using an IBM PC or compatible computer. It provides a summary screen with
color graphic displays of system operating conditions. A detailed, password protected,
tuning screen allows entering of all control parameters, names for control loops,
engineering unit and calibration factors, and other loop data. The program provides
automatic data storage on diskette in LOTUS compatible files and automatic printout at
user selected intervals. It is written in BASIC and is supplied complete with source
listings and operating manual so it can be modified by users.
6.2 CUSTOM APPLICATION PROGRAMS
To begin operation, the following sequence is recommended:
1. Program the host computer to emulate a terminal.
2. Connect the host computer to the ANAFAZE 8 PID and operate the system
manually from the computer keyboard.
3. Write applications software for the host computer and automatically operate the
system.
6.3 TERMINAL EMULATION WITH THE HOST COMPUTER
A software program should be written that directs the host computer to operate
through the communication interface as if it was a terminal. In writing the program the
following commands and characteristics are to be taken into consideration.
A. Configuration Command- The communication interface is to be set for the proper
baud rate, parity, and ASCII character format. The ANAFAZE 8 PID can be set for baud
rates of 300, 600, 1200, 2400, 4800 or 9600. The ANAFAZE 8 PID does not use parity
and requires one start bit, eight data bits, and one stop bit. See section 4.2 for a more
detailed hardware description.
B. Character Output - Characters that are typed on the keyboard are transferred to the
communications interface for output by the software. The ANAFAZE 8 PID requires
commands that are ASCII capital letters and numbers which are terminated by a carriage
return. Section 7 describes the commands.
C. Character Display- Characters that are received by the communications interface from
the ANAFAZE 8 PID need to be transferred to the host computer display. All data sent
from the ANAFAZE 8 PID is terminated by a carriage return and a line feed which
formats the display.
