1 GENERAL DESCRIPTION MELSEC-Q 1.1 Features The Q64TC has the following features. (1) Optimum temperature adjustment control (PID control) (a) The Q64TC exercises temperature adjustment control automatically by merely setting the PID constants (proportional band (P), integral time (I), derivative time (D)) and temperature set value (set value: SV) necessary for PID operations.
Page 15
1 GENERAL DESCRIPTION MELSEC-Q (7) Choice of fine temperature measurement units and various control temperature ranges The temperature measurement unit of each loop can be set to 1°C or 0.1°C in Centigrade or to 1°F or 0.1°F in Fahrenheit, enabling you to choose appropriate resolution for control.
1 GENERAL DESCRIPTION MELSEC-Q 1.2 The PID Control System (1) The PID control system Figure 1.3 indicates the system configuration when performing PID control. Q64TC Set value data storage Control Manipulated value PID operation object data storage process value data storage Sensor Fig.
1 GENERAL DESCRIPTION MELSEC-Q 1.3 About the PID Operation The Q64TC can perform PID control in process-value incomplete differentiation. 1.3.1 Operation method and formula The PID control in process-value incomplete differentiation is an operation method which puts the first-order delay filter as the input for derivative control action, and performs PID operation with the error value (E) after deleting the high-frequency noise component.
1 GENERAL DESCRIPTION MELSEC-Q 1.3.2 The Q64TC actions The Q64TC performs PID operations in reverse action and forward action. (1) Reverse action In a reverse action, the process value (PV) increases toward the set value (SV) as the manipulation value (MV) increases. The reverse action is effective for heat control.
1 GENERAL DESCRIPTION MELSEC-Q 1.3.3 Proportional action (P-action) (1) The proportional action is an action to obtain the manipulation value proportional to the deviation (difference between set value and process value). (2) With the proportional action, the relationship between the changes in the deviation and manipulation value can be expressed in the following formula: MV = where Kp is a proportional constant and is called the proportional gain.
1 GENERAL DESCRIPTION MELSEC-Q 1.3.4 Integral action (I-action) (1) The integral action is an action which continuously changes the manipulation value to eliminate the deviation when there is an deviation. The offset produced by the proportional action can be eliminated. (2) In the integral action, the time from the deviation occurrence until the manipulation value of the integral action becomes that of the proportional control action is called the integral time, and is indicated by Ti.
1 GENERAL DESCRIPTION MELSEC-Q 1.3.5 Derivative action (D-action) (1) The derivative action adds the manipulation value proportional to the change speed to eliminate error when an deviation occurs. The derivative control action can prevent the control target from changing significantly due to disturbance. (2) In the derivative action, the time from the deviation occurrence until the manipulation value of the derivative action becomes that of the proportional action is called the derivative time, and is indicated by T...
1 GENERAL DESCRIPTION MELSEC-Q 1.3.6 PID action (1) The PID action performs control using the manipulation value obtained by merging proportional action, integral action and derivative action. (2) The PID action for the step response when the deviation is constant is shown in Figure 1.11.

7 ONLINE MODULE CHANGE MELSEC-Q 7 ONLINE MODULE CHANGE This chapter describes the specifications of an online module change. Perform an online module change by operating GX Developer. (2) When you want to continue the pre-change operation with the new module after an online module change, save/restore the buffer memory contents.
7 ONLINE MODULE CHANGE MELSEC-Q 7.2 Online Module Change Operations The following gives the operations performed for an online module change. PLC CPU operation : Executed : Not executed FROM/TO GX Configurator (Intelligent function module (User operation) X/Y refresh instruction Device test Initial setting operation) Monitor/...
7 ONLINE MODULE CHANGE MELSEC-Q 7.3 Online Module Change Procedure The online module change procedure is explained separately for the case where GX Configurator-TC was used for initial setting and for the case where a sequence program was used for initial setting. 7.3.1 GX Configurator-TC was used for initial setting (1) Operation stop Turn off the following output signals to stop module operation.
