The type can be selected for each loop. • Time proportional PID relay contact output • Time proportional PID voltage pulse output • Current output (continuous PID control output) • On/off control relay contact output Time Proportional PID The result of PID computation is output using a pulse width of an ON/OFF signal that is proportional to the time.
1.4 PV Input Related Settings Input Range Input Type Select the input source for making input range related settings from the following. Select “RemoteSP” when setting the remote input when you are performing remote/local switching of the SP. When using program control, “RemoteSP” cannot be selected because remote input is not possible.
1.4 PV Input Related Settings PV input value + Bias value 1 Explanation of Functions Bias This function is used to add a constant value (bias value) to the PV and use the result in the display of the PV and control. 2 = Process value in the instrument This function can be used in a case when the PV is less than the true value by a constant amount due to the physical circumstances of the detector.
1.4 PV Input Related Settings Output (b) Ten-segment linearizer approximation Input (a) Square-root Computation of PVs The square-root function is used in the case such as when the differential pressure signal of a restriction flowmeter such as an orifice or a nozzle is converted to a flow signal. You can also set the low-signal cutoff point for the square-root computation. Square-root computation ON/OFF setting: ON or OFF (the initial value is 1.
1.4 PV Input Related Settings 1 PV Tracking ON/OFF Explanation of Functions The PV tracking function is used to prevent radical changes in the PV. When the PV tracking function is enabled (ON), the SP is forced to match the PV once in the following cases. • When powering up. • When switching from manual (MAN) operation mode to auto (AUTO) operation mode. • When switching from operation stop to operation run. • When switching the SP number.
1.5 Contact Input/Output Related Settings Contact Input/Output Terminal The contact signal is input or output from the control output terminal block or the control DIO expansion terminal block indicated in the following figure.
1.5 Contact Input/Output Related Settings Name of Action Detection Action Stop all loop control operation Start all loop control operation Stop/run control (loops 1 to 6) Remote/local (loops 1 to 6) Trigger Trigger Edge Edge Auto/Man operation (loops 1 to 6) Cascade switching (loops 1-2, 3-4) Auto operation (loops 1-2, 3-4) Manual operation (loops 1-2, 3-4) Set target setpoint bits 0 to 3 Start program operation Edge Stops the operation of all internal loops.
1.5 Contact Input/Output Related Settings Note • • • • For a description on how to register contact inputs, see “Setup Items” of section 4.2, “Basic Control Settings > Contact Input Registration/Misc.” On models with the measurement alarm option terminal block /A6R or /A4FR, the actions from “Start/stop” to “Snapshot” can also be assigned to the measurement remote input. For a description on the assignment of actions to the measurement remote input, see “Measurement Remote Input” on page 1-103.
1.5 Contact Input/Output Related Settings 1 Registering the Contents of Contact Output (Style Number S3 or Later) DIO Operation Control Function (Style Number S3 or Later) There are 7 types of DIO available. DI-1: Displays the input status of the specified DI. The status of the internal switches is displayed. DO-1: The status of the internal switches is output to 1 DO. 1 (ON) is output when the internal switches are ON, and 0 (OFF) is output when they are OFF.
1.6 Target Setpoint Related Settings Setting the SP Set the SP, as one of the PID parameters, for each PID number (1 to 8) in the range of EU (0.0 to 100.0% of the measurement span). The PID number in which the SP has been registered is handled as “SP number” when specifying the setpoint and for other purposes. SP Assignment The SP is specified using the SP number. The operation at the time of SP number switching varies depending on the PID selection method.
1.6 Target Setpoint Related Settings 1 Setpoint Limiter Ramp-rate Setting during Target Setpoint Switching When you do not want the SP to change rapidly or when you wish to change the SP at a constant velocity ramp-rate, you can set the velocity ramp-rate (target setpoint ramp-up rate or target setpoint ramp-down rate) for raising or lowering the SP. The specified velocity ramp-rate functions in the following cases. • When the SP is changed. • When the SP number is changed.
1.7 PID Parameter Settings PID Number PID parameter group number. The PID number can be set for each loop. When the PID group number setting is “8”, you can select the PID number from 1 through 8. However, if the PID group number is set to a smaller number, the maximum selectable PID number is decreased accordingly.
1.7 PID Parameter Settings Maximum value of measurement span 1 Explanation of Functions Reference Deviation During control operation, the operation can be switched automatically to a preset PID constant (PID constant with the largest PID number. For example, if the PID group number is 8, the PID constant of PID number 8.) when the deviation between the SP and the PV exceeds the “reference deviation” setting.
1.7 PID Parameter Settings Shutdown Function ON/FF (can be specified only during manual mode using 4- to 20mA current output) The shutdown function closes the control value fully (set the output to 0) exceeding the dead band of the control valve positioner. When this function is turned ON, the control output is set to 0 mA if the manual control output becomes –5.0%. Manipulated output 20.0 mA –5.0% 4.0 mA 3.2 mA 100.0% Output display value 0.
1.7 PID Parameter Settings 1 Preset Output Note If you are setting (changing) the preset output value, presume the case when the preset output is actually used, check the appropriate output value, and set the value. After confirmation, change the preset output only when it is necessary. Explanation of Functions The preset output function outputs a constant value (preset output value) independently from the control output value present up to that point when the following conditions occur.
1.8 Control Output Suppression Settings Anti-Reset Windup (Over-Integration Prevention) There are certain cases in which a large deviation between the SP and PV is present for an extended time such as when control operation is started. In such cases, the control output may reach the high limit of the output limiter and become saturated due to the integral action. In the end, an overshoot may occur.
1.8 Control Output Suppression Settings 1 Output Velocity Limiter Explanation of Functions This function is used to prevent radical changes in the control output to protect the control element and object of control. Since this function negates the derivative action, use caution when using this function on derivative type control. Selectable range of velocity: 0.1 or 100.
1.9 Settings for ON/OFF Control Target Setpoint The target setpoint (SP) is set on the PID Parameter setting display (see page 4-25) in EU (0.0 to 100.0% of the measurement span) in the same fashion as the PID control. On the PID parameter setting display, you select a PID number in the range of 1 to 8 and register one SP for each PID parameter as with other parameters. However, in ON/OFF control, the PID number functions as a SP number.
1.10 Control Alarm Related Settings 1 The following three types of alarm operating conditions are available for selection. • Alarm is always enabled ← initial value • Alarm is disabled when operation is stopped. • Alarm is disabled when operation is stopped or during manual (MAN) operation mode. Alarm Type You can select the alarm type from the following.
1.10 Control Alarm Related Settings Setting the Alarm Value An alarm is registered for each SP of a single control loop. If the SP number (1 to 8) is switched, the alarm value switches accordingly. Since up to 4 alarm types can be assigned for each control loop, four alarm values can be assigned per SP number. You can set the alarm value in the following range. PV high/low limits, SP high/low limits: EU (0 to 100%) of the measurement span.
1.11 Program Control Related Settings 1 When program control is turned ON, select segment PID method (zone PID selection OFF) or zone PID method. • Segment PID method Segment PID method is a function in which the PID setpoint is switched for each segment according to the program pattern setting during program operation. Therefore, this method is suitable for control in which the PID constant is changed during ramp-up and ramp-down in the same PV region.
1.11 Program Control Related Settings Program Pattern Number and Pattern Name From the multiple program patterns available, you can switch the program pattern used in the operation by specifying a number according to the conditions. Each program pattern can be assigned a pattern name. Program pattern number: 1 to 30 (1 to 4 on the /P1 option). Pattern name: Up to 16 characters. You cannot change the pattern number during program control.
1.11 Program Control Related Settings 1 During ramp-up Operation of segment 1 to 99 Final SP of the previous segment (Starting SP at thetime of program operation start) Final SP Explanation of Functions PV 2 Ramp-rate setting 1min or 1h 3 Time The segment assignment method applies to all segments constructing the program pattern. Note that the contents of all program patterns created before are cleared when the segment assignment method is changed.
1.11 Program Control Related Settings • Example in which the 2nd segment of the 1st loop is a soak segment When set to ramp-prioritized PV1 start, the ramp-rate of the 1st loop is prioritized. The program operation start point of the 1st loop will be point C1, D1, or E1 (depends on the PV position a to e at that point). The program operation start point of the 2nd loop (one of the other loops) is at the same time as that of the 1st loop.
1.11 Program Control Related Settings PV a B1 c e 5 A2 D1 C2 E1 3 Program pattern for the 1st loop C1 d 2 4 A1 b 1 Explanation of Functions • Example in which the segment consists of only an up ramp When set to ramp-prioritized PV1 start, the ramp-rate of the 1st loop is prioritized. The program operation start point of the 1st loop will be one of the points from B1 to E1 (depends on the PV position a to e at that point. If the PV position is at point a, program operation will not start).
1.11 Program Control Related Settings Switching Conditions of Program Segments The operating conditions related to the switching of the segments can be specified for each segment. Such conditions include the condition for switching to the next segment and the operating conditions within the segment. The following four conditions for switching the segment are available.
1.11 Program Control Related Settings PV Program operation 2 3 Local operation Last segment SEG.n 1 Explanation of Functions • When the target setpoint tracking is ON When the program operation of the last segment ends, the operation is set to local mode (constant SP) as shown below. At this point, the final SP of the last segment is used continuously as the SP in local mode. The “local SP” can be specified beforehand.
1.11 Program Control Related Settings Wait Operation This function is used to pause the program operation when the PV cannot track the SP. The program is paused to stop the change in the SP and waits for the PV to track the SP. When the PV tracks the SP, the program operation is automatically resumed. This function has the following two types of operation.
1.11 Program Control Related Settings SEG.n SEG.n + 1 Final SP n = 1 to 98 Wait zone Wait zone PV The PV has not reached the wait zone, but the program transits to the next segment when the waittime has elapsed.
1.11 Program Control Related Settings Event Output This function is used to output an alarm at a preset point in time or turn ON the contact output after a given time elapses. The function operates in sync with the progression of the program operation. The event action operates at the start time of the segment to which the event action is assigned. There are two types of event actions: time event and PV event. • Number of time events/PV events that can be assigned to a single segment: 16 each.
1.
1.11 Program Control Related Settings Repeat Function This function repeats the operation over a section of the program pattern consisting of continuous segments. To perform repeat operation, you specify the repeat start segment, repeat end segment, and the number of repetitions (repeat count). Below is a program pattern in which the repeat count = 1, repeat start segment number = 3, and repeat end segment number = 5. You can also specify an infinite number of repetitions.
1.11 Program Control Related Settings 1 Program Operation Start Delay PV SP Delay Explanation of Functions You can set a delay (program start time) in starting the actual program pattern control after carrying out the procedure for starting the program operation. The setting is common to all loops and is valid for a single program operation. The delay cannot be specified during program control. The control output during program control is a preset value.
1.11 Program Control Related Settings When changing the final SP of the segment You can change the final SP during the hold operation. The ON/OFF time of the time event and the segment time are prolonged by the amount of time the operation is held.
1.11 Program Control Related Settings 1 Note Example in which the final SP is changed using the segment time ramp grade setup method The figure below shows the example in which both the final SP and the remaining segment time are changed by changing the final SP using the segment time ramp grade setup method.
1.12 Tuning Selecting Tuning Parameters Up to 21 tuning parameters can be shown on the tuning display. The parameters are initially assigned as shown below. The name of the tuning parameters (such as SP) can be changed using up to 6 characters. In addition to the tuning parameters below, [DR] (control direction) and [H] (relay hysteresis) are available.
1.12 Tuning Auto tuning in progress Auto tuning ends on the third hump. 1 Explanation of Functions Auto Tuning Auto tuning is a function that automatically measures the process characteristics and automatically sets the optimum PID constant. When auto tuning is executed, the control ouput is temporarily turned ON/OFF step-wise (see the following figure). From the hunting period and amplitude of the PV that is generated, the optimum PID constant is calculated and set.
1.13 Measurement Function Overview Measurement Input DC voltage, thermocouple, resistance temperature detector, or ON/OFF signal (contact signal or voltage signal) can be measured. The input signal is A/D-converted at a scan interval of 1 s or 2 s and acquired to the internal memory. In addition, difference computation, square-root computation, and scaling can be carried out on the measured data and acquired to the internal memory.
1.13 Measurement Function Overview 1 Alarm Summary Display Example(For details, see page 1-82) Number of the alarm information displayed on the bottom line Explanation of Functions Number of the alarm information in the internal memory Alarm occurrence channel (channel No. or tag) 2 Alarm No.
1.14 Measurement Function > Measurement Input Related Settings Integration Time of the A/D Converter The CX2000 uses an A/D converter to convert the sampled analog signal to a digital signal. At this point, the sampled data is integrated for a certain period to eliminate the noise that is mixed in the input signal. You can select the integral time from [Auto]/ [50Hz(20ms)]/[60Hz(16.7ms)/100ms].
1.14 Measurement Function > Measurement Input Related Settings 1 Note • Fx = (F max - F min ) Vx - Vmin Vmax - Vmin = Fmin Meanings of the symbols are shown below. Vmin: span lower limit, Vmax: span upper limit, Fmin: scale lower limit after conversion, Fmax: scale upper limit after conversion, Vx: input voltage, Fx: scaling value. If the value inside the root is negative, the computed result is displayed as follows.
1.14 Measurement Function > Measurement Input Related Settings Moving Average The moving average is used to suppress the effects of noise that is riding on the signal. The input signal of the measurement channel is set to the averaged value of the m most current data points (the number of moving-averaged data points) acquired using the scan interval. The number of moving-averaged data points (m) can be set in the range 2 to 16.
Turning ON/OFF the Alarm You can set up to four alarms for each channel. You can set alarms not only on measurement channels but also computation channels. For each alarm, you can set different alarm conditions. Alarm Conditions The following eight conditions (shown as [Type] on the setting display) are available. • Upper limit alarm An alarm occurs when the measured/computed value exceeds the alarm value. • Lower limit alarm An alarm occurs when the measured/computed value falls below the alarm value.
1.15 Measurement Function > Measurement Alarm Related Settings • Delay lower limit alarm An alarm occurs when the measured/computed value remains below the alarm value for the specified time (delay). Delay upper limit alarm example (T is the specified delay) Measured value or computed value X1 X2 X3 X4 Alarm setting T1 T Alarm occurrence Alarm release • Alarm does not occur at T1, because the time is shorter than the specified delay (T).
1.15 Measurement Function > Measurement Alarm Related Settings 1 Alarm Hysteresis Upper limit alarm Lower limit alarm Alarm occurrence Alarm setting Alarm release Measured value Explanation of Functions You can set a width (hysteresis) to the values used to activate and release alarms. Alarm hysteresis prevents frequent activation and release of alarms when the measured value is unstable around the alarm value. The hysteresis is fixed to 0.
1.15 Measurement Function > Measurement Alarm Related Settings AND/OR of Alarm Output Relays When a single alarm relay is shared among multiple alarms, you can select either condition below to activate the alarm output relay. • AND: Activated when all assigned alarms are occurring simultaneously. • OR: Activated when any of the specified alarms is occurring. Set the alarm output relays for taking the AND logic in the following fashion: “I01 (first relay) to Ixx (where xx is the relay number).
1.15 Measurement Function > Measurement Alarm Related Settings 1 When set to non-hold Explanation of Functions Alarm ON 2 Alarm OFF * Relay output ON* Relay output OFF* Relay output ON/OFF is for the case when NO (Normally Opened) terminal is used. If a NC (Normally Closed) terminal is used, the ON/OFF condition is reversed from the condition shown in the left figure.

Appendix 10 Expression Examples The following are simple application examples using expressions. Refer to them when using computation channels. Counter Function This is a counter that counts from 1 to 15. Expression 31 = 31*(31.LT.K02)+K01 K01=1 K02=15 Explanation When the value of channel 31 is smaller than 15, the value of (31.LT.K02) is 1. The value of channel 31 increments by 1 every scan interval. When the value of channel 31 is 15, the value of (31.LT.K02) becomes 0. The value of 31*(31.LT.
Appendix 10 Expression Examples Applies a Lowcut and Highcut to Measured Values and Integrates Them Function Cuts (sets to 0) measured values on channel 1 that are negative or greater than 15, and integrates them. Expression 31 = ((01.GE.K01)AND(01.LE.K02))*01 32 = TLOG.SUM(31) K01 = 0 K02 =15 Explanation When the value of channel 1 is negative, (01.GE.K01) is 0. When the value of channel 1 exceeds 15, (01.LE.K02) is 0.
Appendix 10 Expression Examples Displaying the Average Value Function Averages the measured values on channel 1 every 5 minutes and displays the result. Scan Interval 1 second 300 Channel 31 0 (counter) Expression 31 = 31*(31.LT.K02)+K01 32 = 32*(31.NE.K01)+01 33 = 32/31 34 = (33*(31.EQ.K02))+(34*(31.NE.K02)) K01 = 1 K02 = 300 Channel 32 (integrated value) Channel 33 (average value) Channel 34 (average every 5 min.
