Safety
Watlow Anafaze has made efforts to ensure the reliability and safety of
ANASCAN. Note that in any application failures can occur.
Good engineering practices, electrical codes, and insurance regulations
require that you use independent external safety devices to prevent
potentially dangerous or unsafe conditions. Assume that ANASCAN
can fail or that other unexpected conditions can occur.
For additional process safety, program a computer or other host device
to automatically reload your desired operating parameters after a power
failure. However, this safety feature does not eliminate the need for
other external, independent safety devices in dangerous conditions.
In the event of a CAS reset, ANASCAN will reload the unit with the
current values in computer memory. The user must ensure that this reset
will be safe for the process. Use of ANASCAN does not eliminate the
need for appropriate external, independent safety devices.
Please contact Watlow Anafaze immediately if you have questions
about system safety.

INTRODUCTION
ANASCAN is a user friendly, menu driven software package. It
interfaces the Compact Alarm Scanner (CAS) system to monitor inputs
and alarms for up to 16 independent channels.
You may have only one CAS or a plant wide system with numerous
units. ANASCAN includes numeric and graphic displays, data and
alarm printing, data and alarm logging in text or LOTUS compatible
files, and graphic trending. It runs on an IBM AT 286, 386, or 486, and
true compatible computers. A question and answer format enables
users to quickly define and setup any measurement or application.
NOTE
ANASCAN is sold with a license agreement and can be operated
only on one computer. The license agreement requires registration
with Watlow Anafaze. Watlow Anafaze will send updates at no
charge only to registered users. See registration form at the end of
this manual.

ANASCAN User’s Guide 1
INTRODUCTION
Computer Requirements
Watlow Anafaze sets these computer requirements for running
ANASCAN:
1. IBM AT 286, 386, 486 or other IBM Compatible Computer
2. DOS Version 3.3 or higher
3. Speed: 25 MHz or higher
This speed provides the best performance of the ANASCAN program; it enhances the response of the system to changes and maintains the best screen updates. However, it is not a factor in the
performance of the system since this is maintained independently in
each Watlow Anafaze controller.
4. Memory: 580K bytes free memory or larger
5. Disk Drives: One 40MB hard disk. One 5.25” and/or 3.5” floppy disk
6. Graphics Interface: EGA/VGA
7. RS-232 or RS-485 Serial Interface
The serial communication link required to communicate with more
than one CAS or with a communication cable longer than 50 feet is
RS-485. Watlow Anafaze recommends using the standard serial
interface of RS-232 with an external RS-485 converter.
A converter recommended by Watlow Anafaze is the B&B Electronics RS-232/RS-485 optically isolated converter P/N 485OIC. This
converter has screw terminals for connecting the RS-485 wires and
the DB-25 Male connector for the RS-232 side.
Other recommendations are the Black Box RS-232/RS-485 non-isolated converter P/N ME-836A. The ME-836A connections are the
same except the terminals are labeled with an X instead of a D. The
converter is used for both 2-wire/4-wire systems.
To provide optical isolation, the addition of Black Box opto-isolator
P/N SP400A is highly recommended. The SP400A will normally use
the factory DIP switch settings. All that needs to be done is to connect the cable and the power supply. The SP400A has been used
without any power supplies required as it will draw its power from
the computer and the ME-836A. Always use equipment manufacture
factory recommendations.
To use a PC internal mounted RS-485 card, the Black Box Corp. P/N
IC030 has been used successfully in Watlow Anafaze installations.
Caution must be taken when other communication devices are
installed so as not to conflict with the address or interrupt.
Another PC internal optically isolated RS-485 serial card is BB Electronics model # 3PX0CC1A.

INTRODUCTION
8. Printer Parallel Interface
The printer parallel interface port is required for the Watlow Anafaze
software key. The Watlow Anafaze software key must be installed on
the printer port. System operation of the CAS is not possible without
the software key. [See Software key installation].
9. Battery backed up real time clock (usually battery backed CMOS
chip)
10. EGA/VGA Monitor
The EGA interface card will allow color trend plotting even with a
CGA monitor. The EGA/VGA monitor used with the EGA/VGA
interface provides improved text displays making all the screens easier to read. For systems that require frequent operator changes and
frequent observation, full EGA or VGA is recommended.
11. IBM Graphics Compatible Printer
This graphics printer is required for printing data and alarm logging
features of ANASCAN.

AXXXXXXX.TXT or WK1 alarm logging files
WARNING
Make copies of disks before running the program, and store the
original ANASCAN disks in a safe place. Use the copies to operate the system.
File Locations
360k dual floppy disk system:
Watlow Anafaze recommends that you store the ANASCAN operating
program file and the INSTAL.DAT file on drive A, and all other files on
drive B. Once the program SCANINST is run, you can remove
SCANINST.EXE from drive B to allow more room for data. Do not
remove files from the master disk. This recommendation ensures that
the autoboot feature will bring up the program automatically in the
occurance of a power outage.
720k or higher floppy disk system:
Watlow Anafaze recommends that you store all files of the ANASCAN
operating program on one drive such as A. Use the B drive to store all
recording data by setting up directories as shown in the hard disk system
recommendations.
Hard disk systems:
Watlow Anafaze recommends setting up directories as follows:
ANASCAN - to contain the operating program, system data and job
files
6 ANASCAN User’s Guide
DATALOG - to contain data logging files generated by ANASCAN
ALARMLOG - to contain alarm logging files generated by ANASCAN
Installation Program
INSTALLATION
For easy removal of recorded data, you may install the DATALOG and
ALARMLOG directories on the A or B floppy drives. For automatic
reboot use the B drive recording data to the floppy.
Copy all the supplied files to the ANASCAN directory.
The installation program, SCANINST.EXE, customizes each
ANASCAN program for the application. When typing C:SCANINST
(if it’s on the hard disk), or B:SCANINST (if it’s on drive B), The
installation screen appears and enables you to select parameters used by
ANASCAN.
SCANINST.EXE stores the program setup parameters in a file called
INSTAL.DAT. When run, the SCANINST program reads the
INSTAL.DAT file from the default disk directory. If both files are on
the same disk directory, enter the directory and type SCANINST.
If the SCANINST.EXE and INSTAL.DAT file are on different
directories, enter the disk directory containing INSTAL.DAT and type
SCANINST preceded by the path to the disk directory containing
SCANINST. For example, if INSTAL.DAT is on drive A and
SCANINST.EXE on drive B, type :
B:>A: [Enter] to change the current default drive to A
A:>B:SCANINST [Enter] to start the installation program
If the installation program cannot find INSTAL.DAT, an error message
appears. Verify the location of INSTAL.DAT file.

Number of channels
ANASCAN displays 16 channels with system numbers. The system
channel numbers associated with the CAS channels are indicated in the
installation program as the Begin Channel and End Channel for each
scanner. A 17th channel is reserved for pulse monitoring.
Job/Parameters path
This is the path to the disk directory containing the Job and System
Parameters Data Files. The path would normally be:
B:\ANASCAN\ or .\ current directory (If the system files are on drive
B)
INSTALLATION
C:\ANASCAN\ or .\ current directory (If the system files are on the
hard disk). Notice that the last “\” is added automatically.
Data logging path
This is the path to the disk directory containing the LOTUS or text
[ASCII] data logging files generated by ANASCAN. This directory
must exist before running ANASCAN and turning on data logging.
B:\ANASCAN\DATALOG\ (for floppy disks)
C:\ANASCAN\DATALOG\ or.\DATALOG\ (for hard disks). Notice
that the last “\” is added automatically.
Alarm logging path
This is the path to the disk directory containing the LOTUS or Text
(ASCII) alarm record files generated by ANASCAN. This directory
must exist before running ANASCAN and turning On alarm logging.
Grouping Channels
B:\ANASCAN\ALARMLOG\ (for floppy disks)
C:\ANASCAN\ALARMLOG\ or .\ALARMLOG\ (for hard disks).
Notice that the last “\” is added automatically.
Grouping inputs allows you to divide your system into subsystems. You
can group channels with a common purpose according to your specific
application requirements. One group might be for a furnace or a group
of furnaces; another group might be for common Jobs shared between
devices.
Only the channels of one group are displayed on the Overview screen at
a time. The job parameters are uploaded or downloaded to an individual
group independently. The number of controllers with their total number
of channels must match the number of channels in the grouping. The
channel numbering depends upon the type of input selected in the
SCANINST program.
After assigning the channel numbers to a group, select a type number of
two digits up to 99. This number is the job directory number for the
group and its channels. All groups with the same type number will be
assigned to the same job directory. Creating a new type number creates
a new job directory number in the ANASCAN program.

General grouping rules
•
Create a group when you need to have the channels on the same
Overview screen.
•
Assign the channels to the group you want to have on the same
Overview screen.
•
Create a type number for the new group. This type number can be
assigned to more than one group if they share common jobs through
the ANASCAN.EXE program. However, when using the same
type number for groups, the number of channels must match.
Otherwise a new type number must be used.
NOTE
Type value is used to store jobs specific for that type. The Default
job is only stored under type 01.

START UP
Quick Start Up
•
Ensure time and date are correct in your computer.
•
Type: ANASCAN. Job Select screen appears.
•
Type a job’s name. When starting the first time, enter DEFAULT.
•
Type D for downloading parameters to the CAS, or U for uploading. For
initial testing in the Edit mode, enter D.
•
Overview screen appears.
Start Up Optional Modes
You can start ANASCAN in certain modes by adding parameters to the
command at start up. These command line options include:
•
/e
Operates the program in Edit mode. The program operates normally
but it does not communicate with the CAS. You can operate the
program in Edit mode without any hardware connected to the computer. This mode is useful for initial familiarization, training, and
Off Line job editing.
•
/c
Forces the graphics display into CGA mode. This is necessary on
some computers which are not truly IBM compatible.
•
/d
Operates the program in the Debug mode. This is useful in debugging communications problems. Don’t use it for normal operations. All communications between the computer and the CAS are
displayed on the printer. Therefore, in order to use this mode, the
printer must be connected and ready.
You can use capital or small letters in the command line, and more than
one command line option at a time. For example:
Typing ANASCAN /E /C [enter] will operate the program in Edit mode
with CGA graphics.
