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.
ANASCAN User’s Guide v

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.

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.
ANASCAN User’s Guide 9
INSTALLATION
Group menu
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

Start Up Errors

During Start up, various error messages may appear. The following tables describe these messages, their causes and solutions.
Memory allocation errors
ANASCAN allocates computer memory for the channel parameters, based on the number of channels and options in the system. When ANASCAN reads in the system data files and finds there isnt sufficient memory, these messages may appear:
Message Cause Solution
Insufficient Memory
MEM ERROR: Alarm Queue
Trend Logging Disabled
Not enough memory to allocate data arrays required to run the pro­gram. The program cannot run and it terminates.
Not enough memory to allocate the alarm log memory. The program operates, but the view alarms screen doesnt display alarm queue.
Not enough memory to allocate some or all of the trend logging memory queues. The program operates normally, but the trend plotting is not available.
Check the memory by running the DOS com­mand CHKDSK. At least 580K should be free.
Make sure your computer has 640K memory, and remove any memory resi­dent programs and driv­ers. Check AUTOEXEC.BAT file to see if it runs any memory resident programs. After removing these programs, re-boot the computer.
Same as above.
Same as above.
14 ANASCAN User’s Guide
Disk file errors
While reading in the system files, several reading errors can occur. The system files are SYSSU.DAT, INSTAL.DAT, and PLOT.DAT.
ANASCAN cannot run without these files.
Message Cause Solution
ERROR WHILE READING DATA FILE: xxxxxxxI FILE NOT FOUND
ERROR WHILE READING DATA FILE:xxxxxxx Drive not ready Read fault General failure or Access failure
ERROR WHILE READING DATA FILE:xxxxxxx Path not valid or Invalid disk drive
INVALID DATA FOUND ON DATA FILE:xxxxxxx
The system file does not exist on the indi­cated disk and direc­tory path.
There is a disk drive hardware access fail­ure.
The data disk path that you set in the SCANINST installa­tion program is not valid.
There is corrupted or invalid data in the disk file.
The INSTAL.DAT file should be on the default drive and directory. The other sys­tem files should be on the data file drive and directory path as set in the installation program. If these files are not in the right directories, copy the system files from the backup disks to the appropriate directories.
Run CHKDSK or other diagnostic pro­gram in order to verify that there is no disk drive error. For a floppy drive: make sure that there is a disk in the right drive and that the drive door is closed.
Run SCANINST and verify that the drive and directory path exist and are valid. Dont forget to verify that “\” is at the end of the path entry.
Copy the original data file sent with ANASCAN from the backup disks.
START UP
ANASCAN User’s Guide 15
START UP
Extended start up sequence errors
ANASCAN reads in the status file STATUS.DAT which contains information saved by ANASCAN the last time it was running. Several
errors can occur when reading this file.
Message Cause
Could not find STATUS.DAT start up file
Invalid data value on STA­TUS.DAT start up file
Power Failure Recovery System clock Error
The file could not be found on the data file disk directory set by SCAN­INST. The file may have been erased or cor­rupted.
The file con­tains some invalid data, and ANASCAN assumes that the file was corrupted.
The current system time/ date as saved in the STA­TUS.DAT file were not in a valid range. The computer system clock is not set to valid time and date.
Program
Action
ANASCAN con­tinues with the start up, but since there is no power failure informa­tion available, ANASCAN assumes the Over Power Failure Recovery time Limit action and starts in that mode.
Same as above. Same as above
Same as above. The automatic power failure
As the program is running, the STATUS.DAT file will be established. Therefore, subse­quent starts should have no problem.
recovery feature of ANASCAN requires a cor­rect clock/calendar system. While the computer boots up, verify the following:
Solution
There is a battery backed up clock/calendar in the system.
The battery is good.
Time and date values are correctly loaded.
16 ANASCAN User’s Guide
Communications problems
Message Cause Solution
Failed Communica­tions to CAS Abort start up (Y/N):
ANASCAN cannot com­municate with one of the CAS during the initial sys­tem communications check or during the job downloading/uploading.
Verify that the communications port set in ANAINSTL is the one actually connected to the CAS.
Verify that the communications parameters (baud rate and error checking mode) set in the instal­lation program are those set in the CAS. The CAS communica­tions parameters are set using the front panel keys while in the GLOBAL menu.
Verify that the address of each CAS is unique (for multiple CAS systems).
Verify that the correct version of ANASCAN is running for the CAS being used.
Verify that the wiring is done correctly to the CAS and the computer.
START UP
NOTE
See the respective CAS hardware manual for assistance in checking the communication parameters and verifying the communication wiring.
If there is more than one CAS in the system, ANASCAN will try
supervising those CAS which are operating and communicating correctly. After start up ANASCAN periodically re-checks commu­nications to the failed CAS.
By continuing the start up, the CAS not communicating will be
listed by address on the System Errors window in the System Setup screen. Check the unit listed on the screen. Be sure the address is correct as set on the CAS.
ANASCAN User’s Guide 17

For each of these conditions, you can select one of three start up actions:
1. Operator Select. The program displays the job directory and prompts you for the job to run.
2. Download Profile. The program automatically downloads the speci­fied profile.
3. Upload Profile. The program automatically uploads the specified profile.
When you choose Download Profile or Upload Profile, you will be asked for a job’s name. This can be either a specific job or the last job running when ANASCAN was terminated.
Normal start up action
This is the start up action when the program starts up normally.
Power failure recovery
38 ANASCAN User’s Guide
When the program starts up following a power failure, it determines the time between the power failure and the start up. If the time is less than the power failure recovery time limit, the program takes the under limit start up action. If the time is greater than the power failure recovery time limit, the program takes the over limit start up action. The time limit is entered in hours and minutes.
SYSTEM SETUP
NOTE
In order for the power failure recovery sequence to operate, ANASCAN must be started automatically when the computer is powered up. This is done using an AUTOEXEC.BAT file which contains commands which the computer executes at power up. See DOS operating manual for description of AUTOEXEC.BAT files. The file should contain as its last commands:
1) a command to enter the disk directory containing ANASCAN.
2) a command to stated executing the ANASCAN program.

APPENDIX: Input Scaling

All inputs use the automatic scaling function of the Mx+B calculation. The end points of that calculation are set by HiPV, LoPV, HiRDG, and LoRDG. The default values are set by the input Type selection. Do not adjust these values until you completely understand what those adjustments will do.
The T/C ranges are set in the firmware, and you dont need to adjust those ranges for a proper operating hardware or software. The default values provide correct operating parameters as to stated accuracy and Alarm settings.
For Linear inputs the scaling of the input is required to obtain correct engineering units of the input. This must be done before setting SP and Alarm settings.

Linear Input Scaling

A linear input of 60 mv or less is scaled according to the engineering unit and mv range of the input signal. The CAS has a -10 to 60 mvdc analog input range. All linear inputs must be scaled to that range by scaling resistors on the input.
The HiPV and LoPV is the range of the engineering unit, while the HiRDG is the % of the Hi end signal level mv with reference to 60 mv and the LoRDG is the % of the Lo end signal level with reference to 60 mv.
Example 1
Situation
A pressure sensor that generates a 4-20 milliamp signal is connected to the CAS. The specifications of the sensor state that it generates 4 milliamps at 0.0 PSI and 20 mA at 50.0 PSI.
Setup
The sensor is connected to a channel input set up with a resistor scaling network to produce 60 millivolts at 20 mA. (See the Inputs section of the Installation section of this manual for more information on scaling networks.)
The sensor measures PSI in tenths, so the appropriate display format is -
999.9 to +3000.0.

APPENDIX: Input Scaling
This table shows the input readings.
PV
Displayed
50.0 psi 20 100%

The scaling values are therefore:
Parameter Low Value High Value
Process Value (PV) 0.0 psi 50.0 psi
Input Reading (RDG) 20.0 100.0
Sensor Input Reading (%FS)
Example 2
Situation
A flow sensor connected to the CAS measures the flow in a pipe. The sensor generates a 0-5V signal. The sensor's output depends on its installation. Independent calibration measurements of the flow in the pipe indicate that the sensor generates 0.5 volts at three gallons per minute (GPM) and 4.75 volts at 65 GPM. The calibration instruments are precise to ±1 gallon per minute.
Setup
The sensor is connected to a channel input set up with a resistor voltage divider network to produce 60 millivolts at 5 volts. (See the Inputs section of the Installation chapter for information on scaling networks.)
The calibrating instrument is precise to ±1 gallon per minute, so the appropriate display format is -999 to +3000.
This table shows the input readings.
PV
Displayed
65 GPM 4.75 (4.75 V/ 5.00 V) x 100% = 95%

The scaling values are therefore:
Parameter Low Value High Value
Process Value (PV) 3 GPM 65 GPM
Input Reading 10.0 95.0
