Introduction Introduction ANASOFT is a user friendly, menu driven software package. It provides a powerful computer supervised measurement and control system with data acquisition. ANASOFT is the general name for two products: ANASOFT3 and ANASOFT4. This User’s Guide is for the two products. It uses the general name ANASOFT when referring to both.
Introduction ANASOFT Versions ANASOFT-EV - Expanded Version - provides these features: • Process overview screens (3 different formats) • Loop setup screen, individual loop parameters editing • Maintaining a directory of job files • Displaying and logging process variable alarms • Password protection for various levels of program • Software grouping of Loops • Graphic trend plotting of process variabilities points and output values in real time • Definable startup sequences • Power failure recovery • Pri
Introduction 3. Speed: 25MHz or higher This speed provides the best performance of the ANASOFT 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 control 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 inch or 3.5 inch floppy disk 6. Graphics Interface: EGA/VGA 7.
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 controllers 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.

Can be only 1 Can be either 2400 0r 9600. Set all controllers to the same value. Only one type. Changing one controller’s type would change all others’. 8 ANASOFT User’s Guide Change the screen to the Loop group Edit screen. See Grouping Loops in this section.
Installation Number of loops controller’s type Number of loops 8LS 8 12LS 12 SYSTEM32* 16 or 32 or 48 or 64 16MLS 17 32MLS 33 4CLS** 5 8CLS** 9 16CLS** 17 * For SYSTEM 32, loop numbers greater than 32 are data acquisition channels only, and cannot be used as control loops. ** In CLS controllers, the last loop is a pulse control loop. ANASOFT displays the loops with system numbers.
Installation Alarm logging path This is the path to the disk directory containing the Lotus or Text (ASCII) alarm record files generated by ANASOFT. This directory must exist before running ANASOFT and turning On alarm logging. B:\ANASOFT\ALARMLOG\ (for floppy disks) C:\ANASOFT\ALARMLOG\ or .\ALARMLOG\ (for hard disks). Notice that the last “\” is added automatically. Software Key Installation Install the software key on the computer printer port.
Installation After assigning the loop numbers from any controller in the system to the group, select a type number of two digits up to 99. This number is the job directory number for the group and its loops. 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 ANASOFT program. Group menu General grouping rules • Create a group when you need to have the loops on the same Overview screen.
Installation The hardware consists of the following: Two Watlow-Anafaze 8LS-P-RS controllers. Controller #1 will be installed to handle furnace 2A with four loops of PID control in Area A, two loops of R/S oven control also located in Area A. The last two loops of controller #1 will be used to provide R/S control for one of the presses located in Area A. Controller #2 will be installed in Area B for two loops of PID control for furnace 5B and four loops of R/S control of the two presses located in Area B.
Start Up Start Up Quick Start Up • Make sure the software key is installed. • Set correctly time and date in your computer. • Type: ANA-EV or ANA-RS or ANA-CP depending on your ANASOFT version. Job Select screen appears. • Type a job’s name. When starting the first time, enter DEFAULT. • Type D for downloading parameters to the controller, or U for uploading. For initial testing in the Edit mode, enter D. • Overview screen appears.
Start Up Start Up Sequence • The program checks the computer system hardware, the access to the system disk files, and the presence of the software key. • The program verifies communications to the controllers in the system and the version of the controllers. • Job Directory screen appears. • The program prompts for the job to run. ANASOFT program is supplied with a job named DEFAULT which contains all default control parameters and sets all control outputs off.
Start Up Default Start Up Values The program is shipped to you containing several parameters which are set to initial factory default values. These should be set to desired values by supervisory personal, and they include: • Passwords • Program startup sequences • Data logging parameters • Trend plotting parameters See System Setup for detailed information.
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 ANASOFT allocates computer memory for the loop parameters, based on the number of loops and options in the system. When ANASOFT reads in the system data files and finds there isn’t sufficient memory, these messages may appear: Message Cause Insufficient Memory Not enough memory to allocate data arrays required to run the program.
Start Up 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. ANASOFT cannot run without these files. Message Cause Solution ERROR WHILE READING DATA FILE: xxxxxxxI FILE NOT FOUND The system file does not exist on the indicated disk and directory path. The INSTAL.DAT file should be on the default drive and directory.
Start Up Extended start up sequence errors ANASOFT reads in the status file STATUS.DAT which contains information saved by ANASOFT the last time it was running. Several errors can occur when reading this file. Program Action Message Cause Could not find STATUS.DAT start up file The file could not be found on the data file disk directory set by ANAINSTL. The file may have been erased or corrupted.
Start Up Software key problems Message Cause Solution Software Key not found on printer port. Cannot operate program without key. 1. Attempting to run the operating program without a software key installed on the computer. 2. Installing the software key on a computer connector other than a valid printer port. 3. Installing an incorrect key version. There’s a single controller version and a multiple controller version for accessing more than one controller. 4.
Start Up NOTE See the respective controller hardware manual for assistance in checking the communication parameters and verifying the communication wiring. • If there is more than one controller in the system, ANASOFT will try supervising those controllers which are operating and communicating correctly. After start up ANASOFT periodically re-checks communications to the failed controller.
General Screen Displays General Screen Displays Certain characteristics are maintained on all ANASOFT screens as follows: Title line. Includes screen’s name, current group and job, time and date. When in Edit mode, the words “Edit Mode” appear. Process status box. Four possible messages: 1. Process OK (green). 2. Process warning (yellow). There’s a warning on at least one loop. 3. Process alarm (blinking red). An alarm condition on at least one loop hasn’t been acknowledged. 4. Process alarm (red).
General Screen • Type the new desired value into the new value box. • Press Enter. The new value will be displayed over the original one, and will be downloaded to the controller. If you made a mistake in entering the value and have not pressed Enter yet, use the backspace key to correct. • Use the F4 Key to enter the Job Setup screen and save the changes. If you don’t, upon a new start up, the Job data file will be read from the disk along with the old parameter.

Appendix A: PID Tuning and Appendix A: PID Tuning and Control Introduction This chapter explains PID control and supplies some starting PID values and tuning instructions, so that you can use control parameters appropriate for your system. If you would like more information on PID control, consult the Watlow-Anafaze Practical Guide to PID. The control mode dictates how the controller responds to an input signal.
Appendix A: PID On/Off Control On/Off control is the simplest way to control a process; a controller using On/Off control turns an output on or off when the process variable reaches a certain limit above or below the desired setpoint. You can adjust this limit, since Watlow-Anafaze controllers use an adjustable spread. For example, if your setpoint is 1000ºF, and your limit (spread) is 20ºF, the output switches On when the process variable goes below 980ºF and Off when the process goes above 1000ºF.
Appendix A: PID Tuning and However, a process which uses only Proportional control may settle at a point above or below the setpoint; it may never reach the setpoint at all. This behavior is known as “offset” or “droop”. (This diagram shows a process under proportional control only.) Proportional and Integral Control For Proportional and Integral control, use the Integral term, or Reset, with Proportional control.
Appendix A: PID Proportional, Integral and Derivative Control For an improved level of control, use Derivative control with Proportional or Proportional and Integral control. Derivative control corrects for overshoot by anticipating the behavior of the process variable and adjusting the output appropriately. For example, if the process variable is rapidly approaching the setpoint, Derivative control reduces the output, anticipating that the process variable will reach setpoint.
Appendix A: PID Tuning and Time Proportioning (TP) Time Proportioning attempts to digitally simulate an analog output percentage by turning the output on or off for each time step so that the cumulative average of the output is the desired setting. You must enter a cycle time for TP outputs. The cycle time is the time over which the output is proportioned, and it can be any value from 1 to 255 seconds.
Appendix A: PID Output Digital Filter The output filter digitally filters the PID control output signal. It has a range of 0-255 levels, which gives a time constant of 0-127.5 seconds. Use the output filter if you need to filter out erratic output swings due to extremely sensitive input signals, like a turbine flow signal or an open air thermocouple in a dry air gas oven. The output filter can also enhance PID control.
Appendix A: PID Tuning and Setting Up and Tuning PID Loops After you have installed your control system, tune each control loop and then set the loop to automatic control. (When you tune a loop, you choose PID parameters that will best control the process.) If you don't mind minor process fluctuations, you can tune the loop in automatic control mode. This section gives PID values for a variety of heating and cooling applications.
Appendix A: PID Integral Term (TI) Settings This table shows TI settings vs. Reset settings. TI (secs./repeat) Reset (repeats/min) TI (secs./repeat0 Reset (repeats/min) 30 2.0 210 0.28 45 1.3 240 .25 60 1.0 270 .22 90 .66 300 .20 120 .50 400 .15 150 .40 500 .12 180 .33 600 .10 As a general rule, use 60, 120, 180, or 240 as a starting value for the TI. Derivative Term (TD) Settings This table shows Derivative term (TD) versus Rate Minutes (RM); Rate=TD/60. TD (secs.
Appendix A: PID Tuning and General PID Constants by Application This section gives PID values for many applications. They are useful as control values or as starting points for PID tuning. Proportional Band Only (P) PB: Set the PB to 7% of the setpoint (SP) (Example: Setpoint = 450, so Proportional Band = 31). Proportional with Integral (PI) PB: Set the PB to 10% of SP (Example: Setpoint = 450, so PB = 45). Set TI to 60. Set TD to Off. Set the Output Filter to 2.
Appendix A: PID 66 ANASOFT User’s Guide
Appendix B: Input Scaling Appendix B: 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 and RTD ranges are set in the firmware, and you don’t need to adjust those ranges for a proper operating hardware or software.
Appendix B: Input Example 2: The input signal is 0-50 mvdc representing a range of 2-14 Ph. There is no scaling resistor as the maximum input is less then 60 mv. 50 mv input of 60 mv range = 83.3% 0 mv input of 60 mv range = 0.
Appendix C: ANASOFT-RS Appendix C: ANASOFT-RS This appendix explains the Ramp/Soak (r/s) feature of ANASOFT. Use the ANASOFT User’s Guide as the reference to the standard functions of ANASOFT. For a complete description of the ramp and soak profile and cycle operation, see Watlow-Anafaze Controller Hardware Installation and Operating Manual. What is Ramp/Soak? The r/s feature turns your controller into a powerful and flexible batch controller.
Appendix C: ANASOFT-RS Hardware Requirements In order to operate ANASOFT-RS, all Watlow-Anafaze controllers in the system should include the r/s option. Currently, only 8LS, 12LS, and CLS controllers have this option. During start up, ANASOFT-RS checks each controller in the system to verify that the r/s option is installed. If a controller doesn’t have the r/s option, an error message appears, and the program will not operate with the r/s feature.
Appendix C: ANASOFT-RS Profile Edit Screens These screens enable you to edit the profile. The changes you make on both screens take affect only after you exit the relevant screen and save the profile. Getting Here Press F1 from the Profile Assignment screen. You will be asked for the profile name to edit. After entering the name, The first editing screen appears. This Screen displays the setpoint and the event outputs you want before the profile starts.
Appendix C: ANASOFT-RS . Accumulation of all previous segments up to the edited segment. Changing Total Time also changes Segment Time. Segment’s time duration. Set in minutes:seconds or hours:minutes, depending on the time base defined in the System Setup screen, System Parameters window. Setpoint at the end of the segment. Setpoint’s tolerance.
Appendix C: ANASOFT-RS Function Keys Key Function F1 Copy this profile to another profile name. PgUp / PgDn Change segments. ESC Return to Profile Assignment screen. R/S Time Base Use the System Parameters window of the System Setup screen to select the r/s time base. The time base can be either minutes:seconds or hours:minutes. The time base affects all the other time units of all profiles in the system (Time Remaining, Total Time, etc.).
Appendix C: ANASOFT-RS Status Description Start The loop is ready to start running a cycle. Run The loop is in cycle and the cycle clock is running. Hold The loop is in cycle but the clock isn’t running. You must continue the cycle to start the clock. Tol Wait The loop is in cycle but the clock isn’t running because the process variable is out of setpoint tolerance. Trg Wait The loop is in cycle but the clock isn’t running because the trigger’s conditions are not being met.

The formula for conversion to Celsius is: ºC=5/9 (ºF-32ºF). Failed Sensor Alarm Warns that an input sensor no longer produces a valid signal. For example, when there are thermocouple breaks, infrared problems or resistance temperature detector (RTD) open or short failures. Filter Filters are used to handle various electrical noise problems.
Glossary I Infrared A region of the electromagnetic spectrum with wavelengths ranging from one to 1,000 microns. These wavelengths are most suited for radiant heating and infrared (noncontact) temperature sensing. Input Process variable information that is supplied to the instrument. Input Scaling The ability to scale input readings (readings in percent of full scale) to the engineering units of the process variable.
Glossary N No Key Reset A method for resetting the controller's memory (for instance, after an EPROM change). Noise Unwanted electrical signals that usually produce signal interference in sensors and sensor circuits. See Electromagnetic Interference. Noise Suppression The use of components to reduce electrical interference that is caused by making or breaking electrical contact, or by inductors. Output Control signal action in response to the difference between setpoint and process variable.
Glossary Proportional Band (PB) A range in which the proportioning function of the control is active. Expressed in units, degrees or percent of span. See PID. Proportional Control A control using only the P (proportional) value of PID control. Pulse Input Digital pulse signals from devices, such as optical encoders. R Ramp A programmed increase in the temperature of a setpoint system. Range The area between two limits in which a quantity or value is measured.
Glossary RS-485—An Electronics Industries of America (EIA) standard for electrical characteristics of generators and receivers for use in balanced digital multipoint systems. This is usually used to communicate with multiple devices over a common cable or where distances over 50 feet are required. Setpoint (SP) The desired value programmed into a controller. For example, the temperature at which a system is to be maintained.
Glossary V Volt (V) The unit of measure for electrical potential, voltage or electromotive force (EMF). See Voltage. Voltage (V) The difference in electrical potential between two points in a circuit. It’s the push or pressure behind current flow through a circuit. One volt (V) is the difference in potential required to move one coulomb of charge between two points in a circuit, consuming one joule of energy.
