Page 596: Appendix 3 Related Functions Of Process
Appendix 3 Related Functions of Process This section describes functions related to process control. Auto tuning The auto tuning function detects dynamic characteristics of a control target and automatically tunes the proportional gain (Kp), integral time (Ti), and derivative time (Td) for PID to suitable values. The auto tuning function has two methods: step response method and limit cycle method.
Page 597 Step response method ■Operation method and processing details Perform the following procedure after the manipulated value is held and the process variable is stabilized. Display the auto tuning window of the PX Developer monitor tool.

Page 598 ■Operation details of step response method The manipulated value is output in step form to the actual plant, and each constant is determined according to the maximum slope and equivalent dead time. The following operations are automatically performed. The generated value is saved in P, I, and D areas of the tag data. Manipulated Step manipulated variable variable MV...
Page 599 ■Fine tuning after auto tuning After auto tuning is completed, the change of process variable (PV) in relation to the setting value (SV) is observed on the tuning setting execution window of the PX Developer monitor tool. The optimal values are obtained by adjusting the P, I, and D values.

Page 601 ■Operation details of the limit cycle method ● Generation and measurement of the limit cycle waveform In the AUTO TUNING mode, the PV limit cycle waveform is generated by performing the 2-position ON/OFF operation of MV output three times.

Page 603: Various Controls
Various controls Cascade control The cascade control consists of the primary loop and secondary loop. This control detects disturbance entering secondary loop in an early stage and absorbs them into secondary loop to remove the effect on the process and improve the whole control performance.
Page 604 ■Cascade direct For 2PIDH tags, the CASCADE DIRECT mode can be selected as the control mode. In the cascade direct control, the output value of the primary loop is directly output as that of the secondary loop in the cascade connection. In case of the input sensor failure in the secondary loop, the output result of the primary loop is substituted for and directly output as the output value of the secondary loop since the PID operation result of the secondary loop will be improper.
Page 605 Tracking For tracking, there are two functions as shown below. Item Description At AUTO  MANUAL mode switching, this function prevents the step change caused by the sharp change of the Bumpless function manipulated variable (MV) output and allows MV bumpless switching. Output limiter processing function This function sets the upper/lower limit for the manipulated variable (MV) that is output by PID operation in the AUTO mode.
Page 606 Tracking of loop selector Loop 1 Loop 3 Loop 2 (1) MV of SEL (loop selector) is transferred to the primary loop when the control mode of SEL is manual (MANUAL, COMPUTER MV) or when the variation rate and high/low limiter alarm occurs in other than the MANUAL (AUTO, CASCADE, COMPUTER SV) mode. The primary loop with tracking setting to the SEL is tracked.
Page 607 ■Cascade connection when tracking is not required Connect CASOUT of the primary loop with CASIN of the secondary loop. The tag FB of the secondary loop should be the one with CASIN. (1) Primary loop (2) Secondary loop When tracking is not executed, the operation constant of the secondary loop tag FB is as follows. Variable name Description Range...

Page 612 When the ranges of PVN and MVN are different (the range of A/D conversion module (AIN_4CH) is 0 to 32000, and the range of D/A conversion module (AOUT_4CH) is -32000 to 32000) • Program example for the simulation function (SIMULATION mode) M+P_ENG and M+P_IENG convert FIC001_FB.SIMOUT into FIC001_FB.SIMIN for connection.
Page 613 Override function (OVERRIDE mode) This function enables the PV setting on the pop-up tuning window of the PX Developer monitor tool when a correct input signal cannot be acquired due to a failure of the sensor, limit switch or A/D conversion module.

Stop alarm processing in loop control Stop alarm (SPA) overview When an error related to the loop tag data such as a sensor error (SEA) occurs, the control mode can be changed to MANUAL forcibly by switching the stop alarm (SPA) from FALSE to TRUE. Switch the stop alarm (SPA) from FALSE to TRUE using a user program as necessary.
Page 615 When using the stop alarm in a program, refer to the following example. When a loop sensor error (SEA) of FIC001 occurs Sensor error FIC001 In the example above, the sensor error (SEA) can be acquired with the tag data label of the variable part. Relation between stop alarm (SPA) and other alarm processing The following table shows the relation between the status of the stop alarm (SPA) and other loop alarm processing.
Page 616: How To Use The Output Open Alarm
How to use the output open alarm The output open alarm (OOA) of loop tag data is designed for displaying the wire break detection signal as an alarm on the loop tag FB of the output source when a disconnection is detected on the module FB on the output side. The following shows a program example to feed back a signal from the module FB that is to detect a disconnection to the loop tag FB that is to display it as an alarm.
Page 617: Program Setter Setting Method
Program setter setting method The following describes the setting method of the program setter (PGS) and multi-point program setter (PGS2). Program setter (PGS) ■Operation method The X-Y graph method is used. The output MV is calculated by using the X-Y graph function according to the SV (time) of the whole program.
Page 618 Multi-point program setter (PGS2) ■Operation method Steps (time width and setting value) are registered and the progress of each step is managed. The setting value (SV) is calculated according to the time in the step (T) in each step. ■Relation between the program setting method and each variable Register each step data as shown below.
