 PID Programmable Control

Functions and Parameter Setting:

The PID programmable control includes 8 patterns (Pattern 0 ~ 7). Each pattern contains 8 steps (Step 0 ~ 7) and parameters: link pattern, cycle and the number of steps.

Start Pattern

: This parameter can be set in the operation mode. The user can set up which pattern is the start

pattern for the programmable control. This function is only available when the program is in STOP status.

Step: Includes the settings of the two parameters, set point X and execution time T, indicating that the set point (SV) has to rise to temperature X after the period of execution time T. If the result of the set point X is the same as that of the previous setting, the process is called Soak; otherwise, it is called Ramp. Therefore, the programmable control is also known as Ramp/Soak control. The default setting of the first step program is Soak control. The temperature will first rise to the set point X and remain at X. The total execution time is T.

Link Pattern: For example, if the parameter

execution of pattern 0. If the link pattern is set as

is set as 2, it refers to the execution of pattern 2 will follow the

, it refers to the program will end after the execution of the

pattern is completed and the temperature will remain at the SV for the last step.

Cycle: The additional number of cycles for a pattern. For example, if the parameter

is set as 2, it refers to

pattern 4 has to execute twice additionally, totaling the executions to 3 times including the original one.

The Number of Steps: The number of steps in each pattern (range: 0 ~ 7). For example, if the parameter set as 2, it refers to pattern 7 will execute step 0 ~ step 2 and other steps will not be executed.

The Execution:

1. When the parameter

is set as , the program will start its execution from step 0 of the start pattern.

is set as , the program will stop and the control output will be disabled.

3. When the parameter is set as , the program will stop and the temperature will stop at the SV before

the program stops. When you select

4. When the parameter

auto-selected PID and the program will automatically select a most useful PID parameter based on the current SV. SV

displays will be

~ corresponding to n = 0 ~ 3.

~ : The SV for the selected PID parameter, can be set by the user or auto-generated by auto-tuning.

 Valve Control

Heaters and coolers can be used to control the temperature and the openness of the valve in order to control the flow of the medium. Current and voltage can control the openness of the valve; however, the most direct and economic way to control the openness of the valve is the relay. To control the valve by voltage and current, you can use the DTB series analog output controller. If you tend to use relay for the control output, you have to choose the valve function in DTV series. The two control outputs are relay output for the forward/reverse running of the motor to drive the opening and closing of the valve. Control output1 controls the opening of the valve and control output 2 controls the closing of the valve in order to adjust the position of the valve. In order to detect the position of the valve, DTV is able to receive “feedback signal” and “no feedback signal”. When there is no feedback signal and the valve is fully open, control output 1 will output continuously. If at the moment the valve is fully closed, control output 2 will output continuously. If the valve you use is with feedback output, you can connect the output of the valve to the feedback part of DTV and set

to On to precisely control the openness of the valve. If there is no feedback signal or the feedback signal is

incorrect, and the pre-set openness of the valve is not reached after twice as long as the time set in the parameter

, the program will automatically switch back to the no feedback state. To ensure the correctness of the valve

control, please make sure that you have set up the parameters below:

: Time required from the valve fully closed to fully open. This parameter has to be correct when the valve is without feedback signal; otherwise, the accuracy for the temperature control will be affected. The PID control will correspond to the openness of the valve according to the setting of this parameter.

: DeadBand value of the valve. The parameter is to prevent frequent movement of the valve. For example, assume the DeadBand is 4%, PID control will correspond to the openness of the valve within 4% and the valve will not move within the range unless the value is accumulated and exceeds 4%. If the Deadband value is too small and the valve is set to have feedback signals, moving back and forth of the valve will shorten the life of the valve motor.

when

is set as . When this parameter is set as On, the relay will enable the forward and reverse running of the motor in order to calculate the time needed from the valve fully closed to fully open and the feedback signal of fully closed and open. The feedback signal is the hardware D/A value of the valve control, which is for the calculation of the valve controller.

b) : Upper limit of the valve signal. Set as “On”, can be set automatically or manually.

: Lower limit of the valve signal. Set as ”On”, can be set automatically or manually.

 Auto/Manual Mode Switch

A/M indicator On refers to manual mode; A/M indicator Off refers to auto mode. Besides On/Off, PID, programmable and manual controls, the valve control is also able to forcibly switch to manual control (fixing the openness of the

valve, unit: % from valve fully closed to fully open) when in PID control mode. You simply need to press control mode to switch to manual mode and A/M indicator will be On. Press

again to return to PID control and A/M

in PID

indicator will be Off.

 Upper/Lower Limits of Valve Openness

Assume we would like the maximum openness of the valve to be 80% and the minimum to be 20%, set the parameter

as 80 and as 20, and the valve openness of PID control, programmable control and manual control

will fall within this range.

CRC (Cyclical Redundancy Check) is obtained by the following steps.

1. Load in a 16-bit register FFFFH as the CRC register.

2. Do an exclusive OR operation of the first byte of the data and low byte of CRC register, and place the operation

result back to the CRC register.

3. Right shift the bits in the CRC register and fill the high bits with “0”. Check the removed lowest bit.

4. If the removed lowest bit is “0”, repeat step 3. Otherwise, do an exclusive OR operation of the CRC register and the

value A001H and place the operation result back to the CRC register.

5. Repeat step 3 and 4 until the 8 bits (1 byte) are all right shifted.

6. Repeat step 2 and 5 and calcualte all the bits to obtain CRC check. Please be aware of the high/low byte transmission order in the CRC register.
