1 1.0 INTRODUCTION The ANAFAZE SYSTEM 32 is the key element used to form an innovative measurement and control system. I t combines it s power with an IB M P C or similar c omputer to deliver a n extremely efficie nt data acquisition and pr ocess control sy stem. The SYSTEM 32 concentrates it s power in analog measurement, independent digital loop [...]

2 1.1.3 PROCESS INTEG RITY: The ANAFAZE approach delivers hig h integrity because the SYSTEM 32 independently control s and checks each loop for alarms while it is in turn checked by the computer. Thus a computer failure will not affec t the process and a c ontroller problem will be detected by the computer. F urther integ rity is built in to the S[...]

3 Configurations can start with only the PR OCESSOR I/O MODUL E to provide 32 time proportioning or on/off open loop control outputs. For closed loop control, simply add an ANALOG I NPUT MODULE, either reed relay for 16 inputs, or solid state for 32 inputs. A plug in ANAL OG OUTPUT MODULE provides 16 analog control outputs. Sy stems can be matched [...]

4 1.2.2 ANALOG INPU T MODULES: Two optically -isolated analog input modules are available for the SYSTEM 32. A 16 channel reed relay switching module and a 32 channel solid state switching module.

22 5.0 ANALOG INPU TS Connecting analog sig nals to the ANAFAZE SYSTEM 32 is normally straightforward. Most signals, including thermocouples can be directly connected and mixed in any order. However, some problems may occur that could reduce accuracy and possibly damag e the unit. Sections 5.1 through 5.4 indicate some of the potential areas for co[...]

I t is the ground reference for the measurement section. By switching this reference wit[...]

25 5.6.4 DC CURRENT INPUTS Current inputs from transmitters are accommodated by placing resistors in the input section to convert the current input into a voltage . Different current input ranges are accommodated by selecting the proper resistor values. I n general RC is sele cted to maintain a low sour ce resistance. RA and RC produce the input fu[...]

38 7.0 DETAILED MODULE DESCRIPTIONS 7.1 PROCESSOR I/O MODULE -- A32-P IOM The PIOM is the main processor for the SYS TEM 32 and is required i n each sy stem. The only PIOM option available for standard sy stems is the type of communications i nterface. The PI OM has two microprocessors, an 8031 and 8088. These microprocessors perform all the SYSTEM[...]

39 Direct [Cool]. The outputs are 5vdc at 16ma max imum and are normally used to switch optica lly -isolated solid-state relay s (SSR's). The alarm and status outputs include a global high and low deviation and a watchdog timer which are set by the SYSTEM 32. If ANASOFT-32 is used in the sy stem computer, a global high and low process alarm ou[...]

40 7.2.1 Automatic Calibration The RRAI M includes two additional inputs: a full scale and a z ero signal that are used by the PI OM for automatic full scale and z ero calibration. The zero input is read on one scan to calibrate the analog amplifier zero, on the next scan the full scale input is read to calibrate the amplifier gain. The next two sc[...]

41 7.2.7 Open Thermocouple Detection The RRI AM has upscale open thermocouple detection which is accomplished by placing a small current through the thermocouple leads. The input source impedance may go as high as 200 ohms before rated accuracy is effected. 7.2.8 Address Selection Each RRI AM has a jumper for address selecti on of the RRIAM in the [...]

42 Each AOM has an address Dip switch for address selection of the AOM in the 32 Sy stem. Up to two AOM's may be used in each SYSTEM 32. 7.5 PULSE INP UT MODULE -- A32-PIM The PI M counts up to 32 pulse inputs at maximum pulse rates of 1kHz with 50% duty cy cle pulses. The A32-PIM can only be used in sy stems with an expanded PROCESS OR I/O MO[...]

43 The OPERATOR STATI ON requires ANASOFT-32 to be running in the sy stem computer. I t obtains its readings and changes the setpoints throug h the computer. The OPERATOR STATI ON can select any PIOM and any loop in the system for display and change s. The SP may be viewed for any loop in the system and may , if elected by the customer, be cha nged[...]

44 8.0 PID CONTROL This section provides some common definitions of control terms and information on control loop tuning. 8.1 CONTROL LOOPS A control loop may consist of four or five elements depending upon the placement of the functions of some elements. These elements are defined as follows: PRI MARY ELEMENT: This senses the PROCESS VARI ABLE (PV[...]

45 not be confused with with the ty pe of control output signal: for example pulsed DC voltage or analog output. 8.1.3 ON/OFF CONTROL The simplest way to control the PROCESS VARI ABL E (PV), for example temperature on an oven, to a desired SETPOI NT (SP), operating temperature , is to use ON/OFF contr ol. When the temperature is below the setpoint [...]

46 Kp is the proportional gain, and FSR/Kp is referred to as the proportional band PB . The g ain can be set from 0 to 255 for the SYSTEM 32. Note that when gain is specified in the control equation the output would be different for the same error if a different full scale is used. I f PB is used the FSR cancels out and the PB is independent of the[...]

47 For tempe rature contro l, the most useful and ea siest to use entry is the PB in actual degr ees for the SYSTEM 32. The nominal setting of the PB can be between 5-20% of the SP. Thus, a SP of 300 o F may require a PB of 15-60 o F. To start use 10% of the SP. A good way of establishing a PB setting is to start at a wide PB and then to keep decre[...]

48 Another way of viewing the reset action is to look at the integr al term in the control equation of section 8.1.4. The control output due to this term is the error integra ted over time. Thus a small offset ove r a long per iod of time will incre ase the inte gral sum and c onsequently the control output until the PV is equal to the SP. At this [...]

49 RATE is also used to correct for rapid l oad changes, to slow large capacity processes, and to overcome the slew rates of electric motor actuators. The RATE function responds to the change in the error as a function of time. Mathematically it is the first de rivative of the e rror as a func tion of time [see equation in section 8.1.4]. Thus if t[...]

50 Heating applications normally uses REVERSE ACTION and cooling applications norma lly will use DIRECT ACTI ON. The selection may also be dependent upon the application of two competing mediums of energ y such as in a HEAT/COOL or TEMPERATURE/HUMI DITY applications. 8.1.14 HEAT/COOL DUAL OUTPUTS Certain processes such as plastic molding, plastic e[...]

51 Time proportioning control is a method of using a digital output and an on/off device such as a relay to essentially achieve an analog control signal. When the controller calculates the required control signal, it converts the percent output into a percent duty cy cle and outputs this to the process through the relay . The process itself integra[...]

52 8.1.11 DISTRIBUTED ZERO CROSSING Distributed Zero Crossing [DZC] output is the other time proportioning output available from the SYSTEM 32. This output is primarily for very fast acting electrical heating loads using SSR's. The open air heater coil is an example of a fast acting load. I t should never be used with electro- mechanical relay[...]

The understanding of PI D functions would be useful in tuning loops, but not essential to a successful application of PI D constants to a control loop. 8.2.1 INITIAL VALUES FOR P ID LOOPS The following va[...]

55 8.2.3 OUTPUT F ILTER There is no tuning step for the Output Filter. Adjusting the PI D without the Filter g ives the most accurate response of the control function of the PID modes. The Output Filter may be turn on any time so desired. The number is increased as necessary to reduce cycling of the control output si gnal, thus reducing the c y cli[...]
