20 . Selecting the Controller ode (CTL) automatic control (C mode) automatic control (C) is a mode in which control is performed based on an external setpoint (SV) (through communication or from analog input). automatic control (C),* requiring use of the C mode key, performs different operations depending on the setting of the C-mode (COD) parameter. In cascade setting automatic control (C), there is the analog cascade setting mode (CS) and the computer cascade setting mode (CP). oreover, the computer cascade setting mode (CP) has SPC and DDC modes. *: automatic control is not (internal) cascade control. For cascade control, see.., Control in the Cascade ode (CTL = CS). Control Function automatic control (C) Cascade ode (Parameter COD) nalog cascade setting mode (CS) Computer cascade setting mode (CP) No setting ( ) Communication ode SPC mode (*) DDC mode (*) *: Selection of the SPC or DDC mode is accomplished using communication register LS. These modes cannot be set from the instrument's front panel. Write SPC to LS to use cascade setting automatic control in the SPC mode, or DDC to use it in the DDC mode. The SV key cannot be operated in the SPC mode. The SV and V keys cannot be operated in the DDC mode. For SPC and DDC modes: see YS000 Series Communication Interface User's anual. Backup mode The backup mode is available in the computer cascade setting mode (COD = CP). If writing in watchdog timer from the high-level computer is lost during the period set by YS000's communication watchdog timer, the YS000 determines that the computer has failed in communication. The YS000 then disconnects from it and automatically changes the operation mode. This operating status is called backup mode and there are the following two types of backup mode. Backup mode is set using the backup mode (BOD) engineering parameter. utomatic operation backup mode (BU): The transition of operation from cascade setting automatic control (C) to the automatic operation backup mode (BU) is equivalent to automatic control (). In this mode, the C lamp is lit and the lamp blinks on the instrument's front panel. If the high-level computer recovers communication in this condition, operation changes to cascade setting automatic control (C). anual operation backup mode (BU): The transition of operation from cascade setting automatic control (C) to manual operation backup mode (BU) is equivalent to manual control (). In this mode, the C lamp is lit and the lamp blinks on the instrument's front panel. If the high-level computer recovers communication in this condition, operation changes to cascade setting automatic control (C). I 0B08B0-0EN -

43 . Selecting the Controller ode (CTL) automatic control (C mode) automatic control (C) is a mode in which control is performed based on an external setpoint (SV) (through communication or from analog input). automatic control (C), requiring the use of the C mode key, performs different operations depending on the setting of the C-mode (COD) parameter. There is an analog cascade setting mode (CS) and a computer cascade setting mode (CP) in cascade setting automatic control (C). oreover, the computer cascade setting mode (CP) has SPC and DDC modes. automatic control (C) Cascade ode (Parameter COD) nalog cascade setting mode (CS) Computer cascade setting mode (CP) No setting ( ) Communication ode SPC mode (*) DDC mode (*) *: Selection of the SPC or DDC mode is accomplished using communication register LS. These modes cannot be set from the instrument's front panel. Write SPC to LS to use cascade setting automatic control in the SPC mode or DDC to use it in the DDC mode. The SV key cannot be operated in the SPC mode. The SV and V keys cannot be operated in the DDC mode. For SPC and DDC modes: see YS000 Series Communication Interface User's anual. Backup mode The backup mode is available in the computer cascade setting mode (COD = CP). If writing in watchdog timer from the high-level computer is lost during the period set by YS000's communication watchdog timer, the YS000 determines that the computer has failed in communication. The YS000 then disconnects from it and automatically changes the operation mode. This operating status is called backup mode and there are the following two types of backup mode. backup mode is set using the backup mode (BOD) engineering parameter. utomatic operation backup mode (BU): Operation transitions from cascade setting automatic control (C) to the automatic operation backup mode (BU) equivalent to automatic control (). In this mode, the C lamp is lit and the lamp blinks on the instrument's front panel. If the high-level computer recovers communication in this condition, operation changes to cascade setting automatic control (C). anual operation backup mode (BU): Operation transitions from cascade setting automatic control (C) to manual operation backup mode (BU) equivalent to manual control (). In this mode, the C lamp is lit and the lamp blinks on the instrument's front panel.

71 . Selecting the Controller ode (CTL) automatic control (C mode) The loop cascade setting automatic control (C) is an operation mode in which control is performed based on an external setpoint (SV) (through communication or from analog input). There is an analog cascade setting mode (CS) and a computer cascade setting mode (CP) in cascade setting automatic control (C). oreover, the computer cascade setting mode (CP) has SPC and DDC modes. The loop cascade setting automatic control (C) is set by the C-mode (COD) parameter. Loop automatic control (C) Cascade ode (Parameter COD) nalog cascade setting mode (CS) Computer cascade setting mode (CP) No setting ( ) Communication ode SPC mode (*) DDC mode (*) *: Selection of the SPC or DDC mode is accomplished using communication register LS. These modes cannot be set from the instrument's front panel. Write SPC to LS to use cascade setting automatic control in the SPC mode or DDC to use it in the DDC mode. The SV key cannot be operated in the SPC mode. The SV and V keys cannot be operated in the DDC mode. For SPC and DDC modes: see YS000 Series Communication Interface User's anual. The loop cascade setting automatic control (C) is an operation mode in which control is performed based on an external setpoint (SV) (from analog input). There is an analog cascade setting mode (CS) in this cascade setting automatic control (C). The loop cascade setting automatic control (C) is set by the C-mode (COD) parameter. Setting to the analog cascade setting mode (CS) enables the use of the loop cascade setting automatic control (C). Loop automatic control (C) Cascade ode (Parameter COD) nalog cascade setting mode (CS) No setting ( ) If an external setpoint (SV) has been set, [SV-RT] will be displayed on the control status display section. In manual control (), there are two types of control: a condition in which a setpoint (SV) can be externally set and a condition in which it can be set using a key or through communication. The condition YS000 is in can be identified by [SV-RT] displayed on the control status display section. In the selector mode, the operation mode of the loop and loop cascade setting automatic control (C) differs from the parameter (COD/COD) setting. -6 I 0B08B0-0EN

72 . Selecting the Controller ode (CTL) Backup mode The backup mode is available in the computer cascade setting mode (COD = CP). If writing in watchdog timer from the high-level computer is lost during the period set by YS000's communication watchdog timer, the YS000 determines that the computer has failed in communication. The YS000 then disconnects from it and automatically changes the operation mode. This operating status is called backup mode and there are the following two types of backup mode. backup mode is set using the backup mode (BOD) engineering parameter. Control Function utomatic operation backup mode (BU): Operation transitions from cascade setting automatic control (C) to the automatic operation backup mode (BU) equivalent to automatic control (). In this mode, the C lamp is lit and the lamp blinks on the instrument's front panel. If the high-level computer recovers communication in this condition, operation changes to cascade setting automatic control (C). anual operation backup mode (BU): Operation transitions from cascade setting automatic control (C) to manual operation backup mode (BU) equivalent to manual control (). In this mode, the C lamp is lit and the lamp blinks on the instrument's front panel. If the high-level computer recovers communication in this condition, operation changes to cascade setting automatic control (C). What are REOTE and LOCL REORT (RT): Condition in which the loop 's setpoint (SV) is set by the loop 's cascade setting input (X4) in the selector mode. LOCL (LCL): Condition in which the loop 's setpoint (SV) is set by the [ ], [ ] keys on the instrument's front panel in the selector mode. eaning of Symbols The following shows the operation mode symbols and their meanings: Symbol eaning () anual control () () utomatic control () Loop 's cascade setting automatic control (C) analog cascade setting mode (C) (CS) (CS) status Loop 's cascade setting automatic control (C) computer cascade setting (C) (CP) (SPC) mode (CP) cascade backup mode (SPC) status based on an external setpoint Loop 's cascade setting automatic control (C) computer cascade setting (C) (CP) (DDC) mode (CP) cascade backup mode (DDC) status based on external manipulated output variable Loop 's cascade setting automatic control (RT) or manual control.

Performing Stable Control without brupt Output Changes (PV Proportional Type PID (I-PD)) Description Proportional action (P) and derivative action (D) operate on a process variable (PV) rather than a deviation (E). Because changing a setpoint (SV) does not activate proportional action (P) or derivative action (D), the output (V) does not change abruptly. This control offers stable control characteristics with respect to a characteristic change in the control target, load variations, or disturbance. It is particularly useful for cases where a setpoint (SV) is quickly changed through communication from the high-level system.

121 . Selecting the Control ethod (Selecting Control Type CNT and Control Operation Formula LG)..5 Performing Control with Quick Rise (PID Control with Reset Bias) Description PID control with reset bias is used if it is desired to achieve response with quick rise by positively utilizing reset windup. It is useful for controlling heating processes, pressure release values, etc. Because the output s saturated bias is arbitrarily set in reset bias (RB), the time taken between the instant when a process variable (PV) starts to recover and the instant when a manipulated output variable (V) deviates a limit value can be set. djustment method Increasing the reset bias (RB) improves the response characteristics, shortening the time required for the process variable to reach the setpoint (SV). If RB is set to 00% or higher, corrective action starts after the positions of the setpoint (SV) and process variable (PV) reverse one another. oreover, if RB is set to 0%, PID control in which the reset bias (RB) is disabled is performed. n optimum reset bias (RB) value should be empirically determined by observing the response characteristics. Examples of usage () Batch process temperature control Raw material PV ON/OFF command End of batch SV (set temperature) Start of batch V PV (temperature) Valve Stop valve Steam Simple batch process H RB V (valve opening) V'=H + RB V (for RB = 0%) PV (for RB = 0%) Time Simple Batch Heating Process 065E.ai In a simple batch heating process like the one above, when a batch process ends, the steam stop valve is closed according to the setpoint (SV) and operation mode remains unchanged. The manipulated output variable (V) is limited at the high limit setpoint of V (H) while the batch process is stopped. Note that the manipulated output variable (V ) before passing through the high limit setpoint of V (H) is clamped at H + RB due to the effects of the reset bias (RB) (reset windup status). If the next batch process starts in this condition, the steam valve is opened, causing the process variable (PV) to increase gradually. The release of the manipulated output variable (V) from the output limit point is delayed due to the effects of the reset bias (RB). Therefore, process variable (PV) rise times can be improved. In contrast, if the reset bias (RB) = 0, there is no reset windup; the manipulated output variable is immediately released from the high limit setpoint of V (H) as the process variable starts to rise. This causes the process variable (PV) rise time to be longer. - I 0B08B0-0EN

123 . Selecting the Control ethod (Selecting Control Type CNT and Control Operation Formula LG)..6 Performing Stable Control for the Step Response of Setpoints (djustable Setpoint Filter) Description The values of optimum PID parameters (proportional band (PB), integral time (TI), and derivative time (TD)) that minimize a disturbance (D) that is superimposing on a process variable (PV) do not necessarily agree with the optimum PID parameters that deliver follow-up capabilities for setpoint (SV) change. When YS000 control with the adjustable setpoint filter (SVF), if the setpoint (SV) is changed in steps with the optimum PID parameters for limiting disturbance left unchanged, the response tends to be overshot. Thus, a filtering operation is conducted for the setpoint (SV) to optimally adjust the step response waveform. Operation principle This control adds filters to the setpoint (SV) using the PV derivative type PID (PI-D) control algorithm as a basis. djusting the setpoint filters α (SF) and β (SFB) enables the adjustment of follow-up capability with respect to changing the setpoint (SV) without changing the optimum PID parameters. For the setpoint filters α (SF) and β (SFB), see Effects of Setpoint Filters α (SF) and β (SFB) which follows. The following shows the operation formula for an adjustable setpoint filter (SVF). SVF= +(α TI β TD)S +(TI+TD)S 067E.ai where SVF: adjustable setpoint filter, α and β: setpoint filters, TI: integral time, TD: derivative time, and S: Laplacian operator α = 0 to, β = 0 to α TI β TD 0 If β = 0, TD in the formula = 0 SV +(α TI β TD)S +(TI+TD)S TI S + 00 PB V G P (S) PV (If β = 0, TD in the formula = 0) TD S G P: process transfer function +(TD/m)S djustable Setpoint Filter (SVF) Function Block Diagram 068E.ai -4 I 0B08B0-0EN

Setting setpoint filter α (SF) to a range of 0 < α < enables a follow-up waveform intermediate to those obtained by two control operation formulas (LG) to be achieved in proportion to the magnitude of α. α=, β=0 Control Function Setpoint (SV) α=0, β= Optimum α, β Setpoint (SV) change Response Waveform of djustable Setpoint Filter (SVF) Time 069E.ai Effects of setpoint filters α (SF) and β (SFB) The figure below shows follow-up waveforms of setpoint (SV) generated when setpoint filters α (SF) and β (SFB) are changed from 0 to respectively.

Setpoint filter β (SFB) is a fine-tuning parameter and enables the effects of improvements on follow-up waveforms in which the overshoot is small to be achieved as its value gets greater.

Change a setpoint (SV) in steps to adjust setpoint filter α (SF) so that the desired follow-up waveform is obtained. For control provided with derivative action (D), make further fine adjustments using setpoint filter β (SFB). The recommended values of setpoint filters α (SF) and β (SFB) are 0.5 for setpoint filter α (SF) and 0.0 for setpoint filter β (SFB). () Cases using the self-tuning (STC) function Using the self-tuning (STC) function, determine PID parameters that limit a disturbance (D) and obtain setpoint filter α (SF) so that follow-up is made with respect to a setpoint (SV).

Selecting the Control ethod (Selecting Control Type CNT and Control Operation Formula LG)..7 Performing Control with Gain Characteristics Such as Neutralization Control (Non-linear PID Control) Description Non-linear PID control multiplies a deviation (E) by the non-linear control gain (GG) if the deviation is smaller than the non-linear control gap width (GW), or multiplies it by if it is greater than GW. This control type is useful for achieving follow-up capability for setpoint (SV) changes or for the control of a noisy flow system.

Selecting the Control ethod (Selecting Control Type CNT and Control Operation Formula LG)..8 Performing Control Canceling out Disturbance (Feedforward Control) Description Using only the feedback control results in a delay in recovery of the control target to normal status because corrective action occurs only when the effects of disturbance appear on a process variable (PV). If disturbance can be measured, a correction signal with respect to the disturbance can be applied in advance to the controller s manipulated output (V) to cancel out the disturbance before it affects the control target. This is called feedforward control or feedforward compensation. It is generally used in combination with feedback control.

If a deviation (E) exceeding a batch PID deviation setting value (BD) occurs, the controller outputs the high limit setpoint of V (H) to quickly bring the process variable (PV) to the setpoint (SV). In the case of reverse action, if a deviation (E) falls within the batch PID deviation setting value (BD), the controller determines that the process is in a steady state and changes to PID control. Upon changing to PID control, the controller starts to output from V = H BB to avoid an overshoot in the process variable (PV). where batch PID bias (BB): mount of output pulled back If the deviation (E) exceeds the batch PID deviation setting value (BD) after the controller has switched to PID control, no high limit setpoint of V (H) will be output unless the deviation exceeds the batch PID lock-up width (BL). oreover, in the case of direct action, the controller outputs the low limit setpoint of V (L) instead of the high limit setpoint of V (H), making the batch PID bias (BB) act in the positive direction.

141 . Using the Tracking Function (ulti-function ode Only).. Output Tracking Description Output tracking is the function of switching the manipulated output (V) from the control operation output performed in the controller to a tracking input (X3) signal. When a digital input (DI) signal is received in automatic control () or cascade setting automatic control (C) status, the manipulated output variable (V) is changed to a tracking input value (X3). oreover, switching from control operation output to a tracking input (X3) occurs immediately, while switching from a tracking input (X3) to control operation output occurs beginning with the tracking input (X3) value during switching. Thus, switching is bumpless. tracking input (X3) signal in the multi-function mode is an input from the X3 terminal that has been filtered (tracking input lag time constant (TLG)). Switching operation is performed based on a digital input (DI) signal. The and C lamp lighting status does not change. oreover, [EXT-TRK] is displayed on the LOOP Display s or ETER Display s control status display section (it does not appear in manual control ()). In the cascade and selector modes, tracking input is an input from the X4 or X6 terminal. For this, see.., Control in the Cascade ode (CTL = CS) or..3, Control in the Selector ode (CTL = SELECT), in this manual.

143 . Using the Tracking Function (ulti-function ode Only)..3 Process Variable Tracking (Single-loop ode Only) Description When manual control () is switched to automatic control (), if a deviation (E) becomes large, variations in the manipulated output (V) also become significant (especially, in the case of PV derivative PID (PI-D) control). To prevent this, the setpoint (SV) should be matched with the process variable (PV) during manual control (), so that an abrupt adjustment action does not occur when the operation mode is switched to automatic control (). When the operation mode is switched from manual control () to automatic control (), a setpoint (SV) tracks the process variable (PV).
