SAFETY PRECAUTIONS

㩷

•㩷Read this user’s manual to make sure of correct operation before starting installation, wiring, operation,

maintenance, and inspection of the FC5A series MicroSmart PID modules.

• All MicroSmart modules are manufactured under IDEC’s rigorous quality control system, but users must add a
backup or failsafe provision to the control system using the MicroSmart in applications where heavy damage or
personal injury may be caused in case the MicroSmart should fail.

• In this user’s manual, safety precautions are categorized in order of importance from Warning to Caution.

㩷

Warning

• Turn off the power to the MicroSmart before starting installation, removal, wiring, maintenance, and inspection of
the MicroSmart. Failure to turn power off may cause electrical shocks or fire hazard.

• Special expertise is required to install, wire, program, and operate the MicroSmart. People without such expertise
must not use the MicroSmart.

• Emergency stop and interlocking circuits must be configured outside the MicroSmart. If such a circuit is
configured inside the MicroSmart, failure of the MicroSmart may cause a malfunction of the control system,
damage, or accidents.

• Install the MicroSmart according to the instructions described in this user’s manual. Improper installation will
result in disattachment, failure, or malfunction of the MicroSmart.

㩷

Caution

• The MicroSmart

is designed for installation in a cabinet. Do not install the MicroSmart outside a cabinet.

• Install the MicroSmart

in environments described in this user’s manual. If the MicroSmart is used in places where

the

MicroSmart is subjected to high-temperature, high-humidity, condensation, corrosive gases, excessive

vibrations, and excessive shocks, then electrical shocks, fire hazard, or malfunction will result.

• The environment for using the

MicroSmart is “Pollution degree 2.” Use the MicroSmart in environments of pollution

degree 2 (according to IEC 60664-1).

• Prevent the

MicroSmart from being dropped while moving or transporting the MicroSmart, otherwise damage or

malfunction of the

MicroSmart will result.

• Prevent metal fragments and pieces of wire from dropping inside the MicroSmart housing. Put a cover on the
MicroSmart modules during installation and wiring. Ingress of such fragments and chips may cause fire hazard,
damage, or malfunction.

• Use a power supply matching the rated value. Use of an incorrect power supply may cause fire hazard.

• Use an IEC 60127-approved fuse on the power line outside the

This chapter describes general information and specifications of the FC5A series PID modules. Make effective
use of the PID modules after reading and understanding thoroughly functions and characteristics.

㩷

About the PID Modules

The PID module performs control actions to eliminate the deviation between the set point (SP) and process
variable (PV). The PID module, which is an expansion module, is required to connect to the FC5A series CPU
for use. Depending on the difference of output specifications, the

PID modules are categorized into two types,

and can be used by connecting to a FC5A slim type CPU, or 24-I/O all-in-one type CPU (except 12V DC CPU).
The input channel can accept voltage, current, thermocouple or resistance thermometer signals. The output
channel generates relay output, non-contact voltage (for SSR drive), or current signals.
To configure the PID modules, the Expansion Modules Configuration dialog box in WindLDR is used.
The following table shows the PID module type numbers.

Power Supply for PID Modules

When supplying power to the PID modules, take the following into consideration.

㩷

Using the same power supply for the MicroSmart CPU and the PID module is recommended to suppress the
influence of noise. If the same power source is used for the PID module and MicroSmart CPU module, after the
MicroSmart CPU is started to run, the PID module performs initialization for a maximum of 5 seconds. During
this period, each parameter has an indefinite value. Design the user program to make sure that each parameter
is referred in the CPU module after the PID module operating status is changed to 0001h (Normal operation).

㩷

Wiring of Power Line and I/O Lines for the PID Module㩷

Separate the I/O lines, particularly resistance thermometers, from the power line as much as possible to
suppress the influence of noise.

A. Sensor

Measures temperature of the control target. Thermocouple, resistance thermometer, voltage input,
or current input can be used as the sensor.

B. PID module

Receives the temperature measured by the sensor as the process variable (PV), and calculates the
output manipulated variable (MV) so that temperature difference (deviation) between the process
variable (PV) and the set point (SP) can be eliminated. The output manipulated variable (MV) is
outputted to the actuator as a control signal. Relay output, non-contact voltage output, or current
output can be used as the control signal.

C. Actuator

Receives a control signal from the PID module and turns on the load power supply to the heater.
Electromagnetic switches, SSR, or power controllers can be used as the actuator.

Optimal Temperature Control

The ideal temperature control, as shown in Figure 1, is to control the temperature to correspond with the
set point (SP) regardless of any disturbances. There should be no overshoot or response delay of time
until the temperature reaches the set point (SP).

4-2 FC5A MicroSmart PID Module User’s Manual FC9Y-B1283㩷

In reality, the ideal temperature control shown in Figure 1 on the previous page is almost impossible to
achieve due to a number of complicated factors such as thermal capacity, static characteristics, dynamic
characteristics and disturbances.
Figure 2 is regarded as an optimal temperature control result. Depending on the usage and objective, for
some temperature control applications, suppression of overshoot is required even if the temperature
rises very slowly as shown in Figure 3. For some temperature control applications, it is necessary to
stabilize the temperature as quickly as possible by raising the temperature rapidly even if overshoot is
generated as shown in Figure 4. In general, however, Figure 2 is regarded as an optimal temperature
control. The PID module is designed to raise the process variable (PV) to the set point (SP) as quickly as
possible in order to stabilize the process variable (PV) at the set point (SP) so as to perform the optimal
temperature control. If the temperature fluctuates due to sudden disturbances, the PID module responds
to the fluctuation with speedy response in the shortest possib le time and performs quick control to
stabilize the temperature.

㩷

Characteristics of the Control Target

To perform optimal temperature control, it is necessary to have a good knowledge of the thermal
characteristics of the PID module, sensors, actuators as well as control targets. For example, the PID
module controls a constant temperature oven and its temperature can rise up to 100°C. Even if the set
point (SP) of the PID modules is configured as 200°C, the temperature of the constant temperature oven
rise only up to 100 °C due to its static characteristic.
The characteristic of the control target is determined by the combination of the following 4 factors.

1. Thermal capacity:

This represents how the target is easily heated, and has a relation with the volume size of the control
target.

2. Static characteristic:

This represents the capability of heating, and is determined by the size of the heater capacity.

3. Dynamic characteristic:

This represents the rising characteristic (transitional response) during initial heating. This is a
complicated process involving heater capacity, furnace capacity size and sensor location.

4. Disturbance:

Any change in control temperature causes disturbance. For example, the change of ambient
temperature or supply voltage can cause disturbance.

FC5A MicroSmart PID Module User’s Manual FC9Y-B1283 4-3㩷

Fixed Value Control

The PID module provides 2 control modes, one is the fixed value control and the other is the program control.
The fixed value control is a standard temperature control which performs to eliminate the deviation between
the single set point (SP) and process variable (PV). The program control allows you to define the set point
(SP) that changes as the time progresses so that the process variable (PV) can be controlled to match the set
point (SP) changing as the time progresses. For detail about the program control, see 4-9.
Control actions that can be used for fixed value control and program control are described below.

ON/OFF Control Action

In the ON/OFF control action, when the process variable (PV) is lower than the set point (SP), the control
output is turned on, and when the process variable (PV) exceeds the set point (SP), the control output is
turned off. Overshoot, undershoot, and hunting are generated. ON/OFF control is suitable for processes
which do not require accuracy.㩷
If the proportional band or proportional gain of the PID module parameter is set to 0, the control action
becomes ON/OFF control.

Overshoot, Undershoot

As the temperature of the control target
rises as shown in the figure on the right,
the process variable (PV) sometimes
exceeds the set point (SP) greatly.
This is called overshoot. If the process
variable (PV) drops below the set point
(SP), this is called undershoot.

Hunting

The control result oscillates as shown
in the figure on the right. This is the㩷
the hunting.

㩷
㩷
㩷

P Control Action (Proportional Action)

P control action outputs the manipulated variable (MV) in proportion to the deviation between the process
variable (PV) and the set point (SP) within the proportional band. The control output is ON until the
process variable (PV) reaches the point A that is determined by the proportional band. If the process
variable (PV) exceeds the point A (enters the proportional band), the control output starts turn on/off
according to the control period and the manipulated variable (MV). If the process variable (PV) exceeds
the set point (SP), the control output is completely turned off. While the process variable (PV) rises from
the point A to the set point (SP), the control output ON time decreases and the control output OFF time
increases. Compared to ON/OFF control action, there is no overshoot in P control action, and hunting
becomes less frequent; however, the offset is generated. The P control action is suitable for processes
such as gas pressure control or level control, in which there is no dead time.
If the integral time and derivative time of the PID module parameter are set to 0, the control action
becomes the P control action.

• If the proportional band is narrowed (Proportional gain is made larger)

Because the control output starts turning on/off at around the set point (SP), the time until the process
variable (PV) reaches the set point (SP) is shortened, and the offset is small; however, hunting is
frequent. If the proportional band is greatly narrowed, the control action becomes similar to the ON/OFF
control action.

• If the proportional band is broadened (Proportional gain is made smaller)

Because the control output starts turning on/off at the significantly low temperature from the set point
(SP), overshoot or hunting is reduced; however, it takes time for the process variable (PV) to reach to
the set point (SP), and the offset between the process variable (PV) and the set point (SP) becomes
broadened.

The offset caused by the P control action can be corrected by configuring the reset value. If the reset
value is configured, the proportional band range can be shifted as shown in the figure below. The reset
value can be automatically calculated by the auto-reset function.

PI Control Action (Proportional + Integral Action)

I (Integral) action automatically corrects the offset caused by P control action, and temperature control is
performed at the set point (SP). However, it takes time for the process variable (PV) to be stable if the
process variable (PV) is changed rapidly due to disturbance. PI control action is suitable for the
processes in which the temperature slowly changes.
If the derivative time of the PID module parameter is set to 0, the control action becomes the PI control
action.

• If the integral time is shortened too much, the integral action becomes strong. The offset can be
corrected in a shorter time; however, hunting with a long cycle may be caused.

• If the integral time is extended too much, the integral action becomes weak and it takes time to correct
the offset.

PD Control Action (Proportional + Derivative Action)

Compared with P action, the response to rapid㩷temperature change due to disturbance is faster, the
temperature control can be stabilized in a shorter time, and transitional response characteristic can be
improved in PD control action. PD control action is suitable for the processes in which the temperature
rapidly changes.
If the integral time of the PID module parameter is set to 0, the control action becomes the PD control
action.

• If the derivative time is shortened, the derivative action becomes weak. The response to the rapid
temperature change becomes slower. Because the action to suppress the rapid temperature rises
becomes weaker, the time for the process variable (PV) to reach the set point (SP) is shortened;
however, overshoot can occur.

• If the derivative time is extended, the derivative action becomes strong. The response to the rapid
temperature change becomes faster. Because the action to suppress the rapid temperature rises
becomes strong, the time for the process variable (PV) to reach the set point (SP) is extended; however,
overshoot can be decreased.

The offset caused by the PD control action can be corrected by configuring the reset value. The reset
value can be automatically calculated by the auto-reset function.

PID Control Action (Proportional + Integral + Derivative Action)

P action suppresses the overshoot and the hunting, I action corrects the offset, and D action corrects
rapid temperature change due to disturbance in shorter time. Thus, using PID control action, optimal
temperature control can be performed. The proportional band, integral time, derivative time, and ARW
can be automatically calculated by the auto-tuning (AT).

Auto-Tuning (AT)/Auto-Reset

The optimal temperature control parameters differ depending on the characteristics of the process to control.
For PID control action, the proportional band, integral time, derivative time, and ARW are automatically
configured by performing auto-tuning (AT). For P control or PD control action, the reset value is automatically
configured by performing auto-reset.

㩷 Caution㩷 • Perform auto-tuning (AT)/auto-reset during the trial run.

• If the auto-tuning (AT) is performed near the ambient temperature,

sufficient

fluctuations cannot be given to the process, and auto-tuning (AT)

may fail. In

such case, configure the P, I, D, and ARW values manually.

• Perform auto-reset when the process variable (PV) is stabilized within

the

proportional band.

• Once auto-tuning (AT)/auto-reset is performed, it is un

necessary to perform

auto-tuning (AT)/auto-reset again as long as the process is unchanged.

• When voltage or current input is selected and the auto-tuning (AT

) is performed,

fluctuations are given to the process at the set point (SP)

regardless of AT bias.

• During program control, f

luctuations are given to the process as soon as

auto-tuning (AT) is started.㩷

Auto-tuning (AT)

In order to configure P (proportional band), I (integral time), D (derivative time), and ARW (Anti-Reset
Windup) automatically with optimal values, the auto-tuning (AT) can be performed. The auto-tuning (AT)
gives temperature fluctuation to the process to calculate those parameters . To perform an optimal
auto-tuning (AT), temperature fluctuation is given to the process when the process variable (PV) reaches
near the set point (SP). By setting the AT bias, the temperature to start giving fluctuation can be configured.
The relation between the set point (SP), AT bias, auto-tuning (AT) starting point, and fluctuation starting point
are shown below.

[Process variable (PV) ≤ Set point (SP) - AT bias value]

Auto-reset

During the P control or PD control action, the deviation (offset) between the process variable (PV) and the
set point (SP) is generated when the process variable (PV) is stabilized. By performing auto-reset, the reset
value can automatically be calculated to correct the offset. It is required to perform auto-reset when the
process variable (PV) is stabilized within the proportional band. When the auto-reset is completed, the CPU
module automatically reads all parameters including the calculated reset value from the PID mo dule and
stores those parameters in the data registers. It is unnecessary to perform the auto-reset again as long as
the process is unchanged.
When the proportional band (P) is set to 0 or 0.0, the reset value is cleared.

Auto-tuning (AT)/Auto-reset Perform/Cancel

The Auto-tuning (AT)/Auto-reset function can be performed or cancelled by turning on/off the operation
parameter bits allocated to each channel. For the operation parameter bits, see page 5-10.

㩷

Perform Auto-tuning (AT)
To perform auto-tuning (AT), turn on the control enable/disable bit (Bit0) and auto-tuning (AT)/auto-reset
bit (Bit1) of the operation parameter. P, I, D and ARW values will automatically be configured.
When auto-tuning (AT) is performed during the program control, P, I, D and ARW values of the current
step are configured. While auto-tuning (AT) is performed, the Auto-tuning (AT)/Auto-reset LED (AT0/AT1)
flashes.
When auto-tuning (AT) is completed, the operation parameter Bit1 is automatically turned off, and the
CPU module reads all parameters of the AT performed channel from the PID module and store those
parameters in the data registers. If any parameters in the data registers of the CPU module have been
changed but have not been written to the PID module, those parameters will be overwritten with the
parameters read from the PID module when auto-turning (AT) is finished.

Program Control

The program control allows you to define the set point (SP) that changes as the time progresses so that the
process variable (PV) can be controlled to match the set point (SP) changing as the time progresses. The set
point (SP) and time can be configured for each step. A maximum of 10 steps can be configured and performed.
The set point (SP) can be configured as shown in the following diagram.
The program control is suitable for applications, such as electric furnaces for ceramic industries or food
machineries.

㩷
㩷

㩷

㩷

㩷

Main functions of the program control are described as follows:

Program Pattern and Steps
1 program pattern consisting of 10 steps can be performed per channel.

Program Hold Function
Suspends the progression of the program control while the program control is running and performs the fixed
value control with the set point (SP) at the time that the program control is held.

Advance Next Function
Terminates the current step while the program control is running and proceeds to the start of the next step.

Advance Previous Function
Moves back the progression of the program control while the program control is running.

Wait Function
When a step ends during program control, if the deviation between the process variable (PV) and set point
(SP) is bigger than the wait value, the program control does not move to the next step. The program control
proceeds to the next step once the deviation between the process variable (PV) and set point (SP) becomes
smaller than the wait value.

Repeat Function

When the all steps are executed and the program control is terminated, the program control can be repeated
from Step 0 as many times as the repeat number configured.

Program Control Operation Bits and Status Monitoring

By turning on/off the operation parameter bit, program control progression can be operated. By
monitoring program run status, the current status of program control can be monitored.㩷
For the allocation of operation parameter, program run status, operating status, see pages 5-7 to 5-10.㩷

Program Control Start (Start the program control)

Turn on the program control bit (Bit3) of the operation parameter. Program control starts.

Program Control Stop (Terminate the program control)

Turn off the program control bit (Bit3) of the operation parameter. Program control stops and enters
standby status.

Program Hold (Suspend the program control)

Turn on the program hold bit (Bit4) of the operation parameter. Program control is held (Suspended).
While the program control is held, time progression is suspended, and fixed value control is performed
with the set point (SP) at the time that the program control is held.
While program is held, the Program Control RUN/HOLD LED (R/H0 or R/H1) of the PID module flashes.
To resume the program control, turn off the program hold bit (Bit4).

Advance Next Function (Proceed to the next step)

Turn off to on the advance next step (Bit6) of the operation parameter. The current step is terminated and
the program control is proceeded to the start of the next step. The advance next function is also effective
while the program control is in wait action.

Advance Previous Function (Move back the program control)
Turn off to on the advance previous step (Bit7) of the operation parameter. The progression of the current
step is stopped and the program control is moved back. If the elapsed time in the current step is less than
1 minute, the program control goes back to the start of the previous step. If the elapsed time in the
current step is longer than 1 minute, the program control goes back to the start of the current step.
Even when the advance previous function is executed at Step 0, the program control does not move back
to Step 9 regardless of the program end action.

Current Step Remaining Time

The remaining time of the current step is stored in the “Current Step Remaining Time” of Block 0. The
remaining time is stored in seconds or minutes according to the “Step time unit ” setting.

Current Step Number

The current step number (0 to 9) is stored in the “Current Step Number” of Block 0.

㩷

Program Wait (Perform program wait)

While the program wait is functioning, the program wait bit (Bit5) of the operating status is turned on. If
the condition below is satisfied, the wait function is cancelled, the program control proceeds to the next
step, and the program wait bit (Bit5) is turned off.

Set point (SP) - Wait value ≤ Process variable (PV) ≤ Set point (SP) + Wait value

If the advance next function (Bit6) is turned from off to on or if the program control bit (Bit3) is turned off,
the wait function is canceled.

Program End Output (Program Termination)

When the program control is finished, the program end output bit (Bit6) of the operating status is turned
on. If the program control bit (Bit3) of the operation parameter is turned off, the program end output bit
(Bit6) is turned off. To start program control again, turn off to on the program control bit (Bit3) of the
operation parameter.

Action after Power Is Restored

When the power is restored, every bit of the operation parameter excluding the program hold bit stored in

*2: While the program control is running, the PID module saves the program control status every 6 minutes after the

program control is started (after the program control bit is turned on). The program control status is also saved at
the start of each step. If the power to the PID module is turned off while the program control is running, the PID
module resumes the program control from the latest saved point.

For example, if the power to the PID module is turned off in 7 minutes after the program control is started at step
0, the PID module resumes the program control at the status (1) when the power is restored. If the power to the
PID module is turned off in 4 minutes after the program control enters step 1, the PID module resumes the
program control at the status (2) when the power is restored. If the power to the PID module is turned off in 2
minutes after the program control enters step 2, the PID module resumes the program control at the status (3),
which is the start of step 2, when the power is restored.

The set point (SP) configured for each step is handled as the set point (SP) at the end of the step. The
time configured for each step is the process time of each step.

When the program pattern is configured as shown in the above table, the following control is
performed at each step:

[Step 0]: The set point (SP) is gradually risen to 100

°C in 60 minutes.

When the step 0 ends, the wait function works so that the program control does not
proceed to the step 1 until the process variable (PV) reaches 90

°C.

[Step 1]: The fixed value control is performed at 100

°C of the set point (SP) for 60 minutes.

[Step 2]: The set point (SP) is gradually risen to 800

°C in 5 hours.

When the step ends, the wait function works so that the program control does not proceed
to the step 3 until the process variable (PV) reaches 790°C.

[Step 3]: The fixed value control is performed at 800

°C of the set point (SP) for 30 minutes.

Heating/Cooling Control

When it is difficult to control the target process with heating control only, cooling control can be added to
perform the heating/cooling control. Control results derived from the set point (SP) and process variable (PV)
are outputted to 2 outputs, heating output (CH0) and cooling output (CH1). If the process variable (PV) is
higher than the set point (SP), cooling output will be turned on. If the process variable (PV) is lower than the
set point (SP), heating output will be turned on. The area in which both heating and cooling outputs are turned
on can be configured as overlap. The area in which neither heating output nor cooling output is output can be
configured as dead band.

Example: Heating/Cooling control uses both heating and cooling outputs and is suitable for the heat producing

processes such as extruders or for temperature control at near ambient temperature such as
environment testers.

Difference Input Control

Difference input control is the control to keep the input difference between input CH0 and input CH1 at the
same level. When the difference input control is selected, input CH0 and input CH1 are independently
measured, and the difference between those inputs is used as process variable (PV). PID module controls
output so that the difference between those inputs is matched to the set point (SP).

Example 1: Controlling the liquid level difference of 2 tanks
The PID module measures the liquid levels of 2 tanks and controls output to keep liquid level difference
between Tank A and Tank constant.

Cascade Control

The cascade control combines two PID controls to form one feedback loop to control a single target. The
cascade control is effective for applications in which the delay time or dead time is considerably large. When
delay time is large, it takes a long time for the process variable (PV) to change after the output manipulated
variable (MV) is changed. By using the cascade control, highly stable control can be realized for such
applications, though it takes time for the process variable (PV) to reach the set point (SP).
CH1 control is used as the master and CH0 control as the slave of the cascade control. The output
manipulated variable (MV) of the master (CH1 control) becomes the set point (SP) of the slave (CH0 control),
and the control result of CH0 is outputted from the CH0 output. The output manipulated variable (MV) (0 to
100%) of the master (CH1 control) is corresponded to the set point (SP) of the slave (CH0) according to the
external SP input linear conversion minimum and maximum values. For example, when the external SP input
linear conversion minimum value is 100°C and the maximum value is 400°C, the output manipulated variable
(MV) (0 to 100%) of the master (CH1 control) is converted as follows: 0% is converted to 100°C, 50% is
converted to 250°C, and 100% is converted to 400°C.
When a system using the cascade control is designed, it is required that the slave (CH0 control) have smaller
delay time and faster response comparing to the master (CH1 control).

Example: The cascade control is used for an application in which the heat quantity of a heater is controlled
using a power controller in order to control the temperature of the control target as shown in the figure below.
It is also possible to utilize the heating/cooling control to prevent a rapid temperature rise of the control target
by using a fan as the cooling output.

How to perform auto-tuning (AT) in cascade control

Auto-tuning (AT) can be performed for the cascade control with the following procedure.

Auto-tuning (AT) for the slave (CH0)

1. Turn off the CH0 and CH1 control enable bits of the operation parameter to disable the CH0 and CH1
controls.

2. Copy the set point (SP) of the master (CH1) to the set point (SP) of the slave (CH0), the external SP
input linear conversion maximum value, and the external SP input linear conversion minimum value
in order to fix the set point (SP) of the slave (CH0).

3. Turn on the CH0 and CH1 control enable bits of the operation parameter to enable the CH0 and CH1
controls. Turn on the CH0 auto-tuning (AT)/auto-reset bit of the operation parameter to start the
auto-tuning (AT) for the slave (CH0).
When auto-tuning (AT) is completed, P, I, D and ARW values of the slave (CH0) will be automatically
configured.

Auto-tuning (AT) for the master (CH1)

4. Turn off the CH1 control enable bit of the operation parameter to disable the CH1 control.

5. Store the original values in the external SP input linear conversion maximum and minimum values.

6. Turn on the CH1 control enable bit and CH1 auto-tuning (AT)/auto-reset bit of the operation parame­ter to enable the CH1 control and start the auto-tuning (AT) for the master (CH1).
When auto-tuning (AT) is completed, P, I, D and ARW values of the master (CH1) will be automati­cally configured

Notes:

• When using the cascade control, store the same set point of the master (CH1) to the set point (SP) of the slave

(CH0).

• The output manipulated variable (MV) (0 to 100%) of the master (CH1) corresponds to the set point (SP) of the

slave (CH0). The range of the set point is the external SP input linear conversion minimum value to the external
SP input linear conversion maximum value.

• Depending on each control target, optimum values of P, I, D and ARW may not be calculated with the auto-tuning

(AT). In such case, configure those parameters manually based on the P, I, D and ARW values calculated with the
auto-tuning (AT).

Program Example of Auto-tuning (AT) for Cascade Control

A sample ladder program to execute the auto-tuning (AT) for the master (CH1) and slave (CH0) in the
cascade control is described in the following page.

5: DEVICE ALLOCATION OF PID MODULE

This chapter describes the valid devices, control registers, control relays, and data register allocation for the
PID module.

Device Allocation of PID Module

The PID module is used by connecting to the MicroSmart CPU module. To use the PID module, allocate the
data register and internal relay to the PID module, configure the initial parameters using W indLDR, and down­load the user program and the parameters to the CPU module and the PID module. The initial parameters are
downloaded to the CPU module along with the user program. The CPU module reads/writes data from/to the
PID module according to the parameters configured in WindLDR.

The PID module parameters consist of 26 data blocks divided according to the function and frequency of use
of each parameter as shown in the table below. All blocks to be used are allocated to the data registers in the
CPU module. The parameters of each block can be read from/written to the PID module using the allocated
control relays.

Block 0 includes parameters such as operating status, current process variable (PV), set point (SP), and output
manipulated variable (MV) of the PID module. The CPU module reads those parameters from the PID module
every scan. The control status and alarm status of the PID module can be monitored with Block 0 parameters.

Block 1 includes the set point (SP), manual mode output manipulated variable (MV), and operation parameters
of the PID module. Those parameters are written to the PID module every scan. Operations such as changing
the set point (SP) for the fixed value control, enabling/disabling the control, or performing auto-tuning (AT) can
be carried out.

Blocks 2 and 3 include basic parameters of the PID module. By turning the control relay from off to on,
parameters can be read from/ written to the PID module.

Blocks 4 and 5 include initial setting parameters of the PID module. Parameters that are usually not changed
during the operation are stored.

Blocks 10 to 19 and 30 to 39 include parameters of each step of the program control. By turning the control
relay from off to on, parameters can be read from/written to the PID module.

Block data are read from/written to the
PID module a

Control Register

The PID module occupies a maximum of 590 data registers (minimum 190 data registers) per PID module. The
occupied number of data registers varies between the fixed value control mode and program control mode.
When both CH0 and CH1 are in fixed value control mode, 190 data registers are occupied, including the first
data register designated. When either CH0 or CH1 is in program control mode, 590 data registers are occupied,
including the first data register designated.

Precautions when Connecting Four PID Modules to All-in-One Type CPU Module

2000 data registers (D0 to D1999) are allocated to the all-in-one type CPU module. When four PID modules
are connected to the all-in-one type CPU module, a maximum of six program controls can be conducted with
three PID modules among the four PID modules.

The configurations shown in the examples 1 and 2 are not possible because the total number of occupied data
registers exceeds 2000.

Notes about the control relays:

• The control relay +0: Reading all parameters
When this bit is turned off to on, all parameters stored in the ROM of the PID module are read out and stored in the data
registers in the CPU module.

• The control relay +1: Loading initial values
When the user program is downloaded to the CPU module, the initial values of all parameters for the PID module are
also downloaded and stored in the ROM of the CPU module. When this bit is turned off to on, the initial values stored in
the ROM are loaded into the data registers (RAM).

• The control relay +2: Writing all parameters
When this bit is turned off to on, all parameters stored in the data registers are written to the ROM of the PID module.

• The control relay +3 through +27: Writing blocks 2 to 5, 10 to 19, and 30 to 39
When the writing bit is turned off to on, the corresponding block parameters stored in the data registers are written to the
ROM of the PID module.

Data Flow of the PID module parameters

1. All parameters are read out from the PID module and stored in the data registers in the CPU module
when the reading all parameters bit is turned off to on.

2. Initial values stored in the ROM of the CPU module are loaded to the data registers when the loading
initial values bit is turned off to on.

3. All parameters stored in the data registers are written to the PID module when the writing all parameters
bit is turned off to on.

4. The block parameters stored in the data registers are written to the PID module when the block writing bit
is turned off to on.

Examples of changing the PID module parameters using the control relay

All parameters of block 1 to 5, 10 to 19, and 30 to 39 can be changed using a ladder program. The following
examples demonstrate how the parameters of the PID module can be changed. See pages 5-7 to 5-24 for
detail about each block parameter.

Example 1: Changing Block 1 Parameter

The set point (SP) of CH0 control (D1020) is changed to 250.5°C. In this example, D1000 is allocated to the
control register and M500 is allocated to control relay.

When the new set point 2505 is stored in D1020

*1

, it is automatically written to the PID module *2.

Ladder Program Example:
When external input I0 is turned on, the set point (SP) of CH0 will be changed to 250.5°C.

*1: When the input range has a decimal point, store the value multiplied by 10 in the data register.
*2: When the control register is D1000, Block 1 parameters are stored in D1020 to D1025. These values are written to

the PID module every scan.

Example 2: Changing Block 2 Parameters

The integral time (D1027) is changed to 150 seconds and the derivative time (D1028) is changed to 45
seconds for CH0 control. In this example, D1000 is allocated to the control register and M500 is allocated to
control relay.

Those parameters can be changed with the following procedure.

1. Turn on M500 (Reading all parameters). All PID module parameters are read out from the PID module
and stored in the data registers.

*1

2. Store 150 in D1027 (integral time of CH0) and 45 in D1028 (derivative time of CH0).

3. Turn on M503 (Block 2 writing)

*2

. The integral time (150 sec) and derivative time (45 sec) will be written

to the PID module.

Ladder Program Example:

*1: If the reading all parameters bit (M500) is turned on, all PID module parameters are read out from the PID module

and stored in the data registers. Block 2 parameters are stored in D1026 to D1052.

*2: Block 2 parameters stored in D1026 to D1052 are written to the PID module. The parameters of the other blocks

are not written.

When I0 is turned on, the new set
point 2

505 is stored in D1020 [set

point (SP) of CH0].

Example 3: Changing Block 4 Parameter

The PV filter time constant (D1063) of CH0 is changed to 1.5 seconds. In this example, D1000 is allocated
to the control register and M500 is allocated to control relay.

The parameter can be changed with the following procedure.

1. Turn on M500 (Reading all parameters). All PID module parameters are read out from the PID module
and stored in the data registers of the CPU module.

*1

2. Turn off D1022.0 (Control enable bit of CH0). CH0 control of the PID module will be disabled.

3. Store 15 in D1063 (PV filter time constant of CH0).

*2

4. Turn on M505 (Block 4 writing).

*3

5. Turn on D1022.0 (Control enable bit of CH0). CH0 of the PID module will be enabled.

Ladder Program Example:

*1: If the reading all parameters (M500) is turned on, all PID module parameters are read out from the PID module and

stored in the data registers. Block 4 parameters are stored in D1053 to D1102.

*2: For a value with a decimal point, store the value multiplied by 10 in the data register.
*3: Block 4 parameters stored in D1053 to D1102 are written to the PID module. The parameters of the other blocks

are not written.

Note: If parameters of block 4 or 5 are changed while CH0 or CH1 control is enabled in the PID module, an unexpected
operation of the PID module may be caused. It is recommended that the control channel of the PID module be disabled
before changing the parameters of block 4 or 5.

User Program Download

The user program contains the user program and the PID module parameters (initial values) configured
in the PID Module Configuration dialog box. After the user program is downloaded to the CPU module,
the CPU module can communicate with the PID Modules through the allocated data registers.

After the user program download, the following actions will be taken depending on whether Write PID
Module parameters after download in the Download dialog box is checked or not.

When Write PID Module parameters after download is checked:
After the user program is downloaded to the CPU module, the PID module parameters configured in the
PID Module Configuration dialog box are written to the CPU module and the connected PID modules.

When Write PID Module parameters after download is not checked:
After the user program is downloaded to the CPU module, the PID module parameters are not written to
the PID module.

When Write PID Module parameters after download is checked, after the user program is downloaded
to the CPU module, the PID module parameters configured in the PID Module Configuration dialog box
will be written to the data registers in the CPU module and all PID modules configured in the Expansion
Modules Configuration dialog box. However, if a PID module is not connected to the configured slot,
writing parameters to the PID module will fail. Even after writing parameters to one PID module failed,
WindLDR continues to write the parameters to all PID modules configured in the Expansion Modules
Configuration dialog box.

If writing parameters fails, connect the PID module to the CPU module and write parameters to the PID
module again.

To write the PID module parameters without downloading the user program to the CPU module, take the
following steps:

1. Connect the PID module to the CPU module.

2. Open the PID Module Configuration dialog box for the slot.

3. Click on Write All Parameters button.
All the configured parameters will be written to the data registers in the CPU module and the PID
module.

User Program Upload

When the user program containing the initial parameters of the PID modules is uploaded from the CPU
module, the initial values will be restored. The parameters saved in the PID module will not be read.

How to restore data register values when a keep data error has occurred

If more than 30 days pass since the power to the CPU module is turned off, values stored in the data
registers will be lost. When the data register values are lost, after the power is turned on, restore the PID
module parameters in the data registers of the CPU module using either of the following methods, and
then enable the control of the PID module.

Method 1: Use the parameters stored in the PID module

The parameters stored in the PID module can be read out and stored in the data registers of the CPU
module with one of the following procedures:

Procedure 1: Using WindLDR

1. Open Expansion Modules Configuration dialog box in WindLDR.

2. Select the slot number of the connected PID module and open the PID Module Configuration dialog
box.

3. Click on Read All Parameters button to read all parameters from the PID module.

4. Configure the set point (SP) and the manual mode output manipulated variable in the PID Module
Configuration dialog box. *1

5. Click on Write All Parameters button.
When the control of the PID module is enabled, the PID module will start operating with the
downloaded parameters.

Procedure 2: Using the user program

1. Turn off to on the reading all parameters relay (control relay + 0).

2. Configure the set point (SP) and the manual mode output manipulated variable if necessary. *1
When the control of the PID module is enabled, the PID module will start operating with the
configured parameters.

*1: Because the block 1 parameters are not saved in the PID module, it is required to configure those parameters.

Method 2: Use the default parameters stored in the ROM of the CPU module

When the PID module parameters are configured in the PID Module Configuration dialog box and the
user program is downloaded to the CPU module, the PID module parameters (initial values) will be
saved in ROM of the CPU module. Those initial values can be loaded to the data registers in the CPU
module, and the PID module can be operated with those initial values with the following procedure:

1. Turn off to on the loading initial values relay (control relay + 1).

2. Turn off to on the writing all parameters relay (control relay + 2).
When the control of the PID module is enabled, the PID module will start operating with the default
values.

Cascade Control:

The cascade control is an advanced control that uses 2 inputs [CH1 as a master (primary control) and CH0 as
a slave (secondary control)] to control a single process.

Master (CH1) calculates the output manipulated variable (MV) according to the process variable (PV) and the
set point (SP). The output manipulated variable (MV) of the master (CH1) is used as the set point (SP) of the
slave (CH0). With the obtained set point (SP), the slave (CH0) calculates the output manipulated variable (MV)
and controls the output CH0.

When the cascade control is used, the output CH1 is unused. When the output type is current, the output CH1
is 4 mA. When the output type is voltage, the output CH1 is 0 V. When the output type is relay, Output CH1 is
turned off. When heating/cooling control is enabled, output CH1 is used as the cooling output.
Output manipulated variable (MV) (0 to 100%) of the master (CH1) is converted using the external SP input
linear conversion minimum and maximum values and is used as the set point (SP) of the slave (CH0).

Example: When the external SP input linear conversion minimum value is 0°C and the external SP input linear

conversion maximum value is 1000°C, the set point (SP) of the slave (CH0) is decided as follows:
When master (CH1) output manipulated variable (MV) is 0%: 0°C
When master (CH1) output manipulated variable (MV) is 50%: 500°C
When master (CH1) output manipulated variable (MV) is 100%: 1000°C

The one of the following output functions can be selected as the Output CH0 Function.

Output (CH0): The output of the CH0 control is outputted from output CH0

Output (CH1): The output of the CH0 control is outputted from output CH1

When Output (CH1) is selected, CH1 parameters are used for the control period and the output manipulated
variable (MV) upper and lower limits. CH0 parameters are used for all other parameters, such as the output
manipulated variable rate-of-change, output on/off hysteresis, and manual mode output manipulated variable.

When output type is voltage/current, output CH0 is 0V/4mA.

Both Outputs (CH0, CH1): The output of the CH0 control is outputted from both outputs CH0 and CH1
The control period and output manipulated variable (MV) upper and lower limits of CH0 and CH1 are used for
the corresponding output. CH0 parameters are used for all other parameters, such as, the output manipulated
variable rate-of-change, output on/off hysteresis, and manual mode output manipulated variable.

PID Module Configuration - Input Parameters Details

Input parameters for CH0 control are described here. Input parameters for CH1 control are the same as those
of CH0 control. However, the position from the control register for each parameter differs. For details about the
positions from the control register for CH1 control, see 5-17 to 5-20.

(1) Control Register+58: Input Range

Select input type and input range unit (Celsius or Fahrenheit). For details about the input range, see 6-10.

(2) Control Register+62: PV Correction

If the sensor cannot be installed to the location of the control target, the temperature measured by the sensor
may deviate from the actual temperature of the control target. When a target is controlled with multiple PID
modules, the measured temperatures may not match due to the differences in sensor accuracy or dispersion
of load capacities even though the set points (SP) of those PID modules are the same. In such cases, the
process variable (PV) of the PID module can be adjusted to the desired temperature by using the PV
Correction. The process variable (PV) after the PV correction should be within the control range (See 9-4). For
example, when type K thermocouple (-200 to 1370°C) is selected as input type, configure an appropriate PV
correction value so that the process variable (PV) after the PV correction does not exceed the control range
(-250 to 1420°C) [(Input range lower limit - 50°C) to (Input range upper limit + 50°C)].

When the process variable (PV) after the PV correction is within the control range, the PID module controls the
temperature based on the process variable (PV) after the PV correction. When the process variable (PV) after
the PV correction is out of the control range, the under or over range error occurs and the control output is
turned off

The process variable (PV) after the PV correction can be calculated using the following formula:
Process variable (PV) after the PV correction = Process variable (PV) + (PV correction value)

Example 1: When process variable (PV) is 198°C
If the PV correction value is 2.0°C, the process variable (PV) will be 200.0°C (198°C + 2.0°C).
If the PV correction value is -2.0°C, the Process variable (PV) will be 196.0°C (198°C - 2.0°C).

Example 2: By setting the PV correction value for the PID module to 10.0°C, the process variable (PV) of the
PID module is adjusted from 190°C to 200°C.

(3) Control Register +63: PV Filter Time Constant

The PV filter function is a software filter to stabilize the process variable (PV) affected by fluctuating processes,
such as the pressure or flow rate, by calculating first-order lag of the process variable (PV). Even if the process
variable (PV) changes as shown in the Figure 1, when the PV filter time constant is configured, the process
variable (PV) changes as shown in the Figure 2. After the PV filtering process, the process variable (PV)
reaches 63% of the process variable (PV) in T seconds.
If the PV filter time constant is too large, it adversely affects the control results due to the delay of response.

Example: If the least significant digit of the process variable (PV) is fluctuating, the fluctuation can be
suppressed by using the PV filter time constant.

Linear Conversion Function

The diagram below shows an example of the linear conversion. When the linear conversion maximum value is
5000 and the linear conversion minimum value is 0, the current input (4 to 20mA DC) is linearly-converted as
shown in the diagram.

Set Point (SP) Upper Limit/Linear Conversion Maximum Value

When input type is thermocouple or resistance thermometer, the linear conversion is disabled. The linear
conversion maximum value is used as the upper limit of the set point (SP). When input type is voltage/current,
configure the maximum value of input CH0 as the linear conversion maximum value. Any value within the valid
input range can be configured.

Set Point (SP) Lower Limit/Linear Conversion Minimum Value

When input type is thermocouple or resistance thermometer, the linear conversion is disabled. The linear
conversion minimum value is used as the lower limit of the set point (SP). When input type is voltage/current,
configure the minimum value of input CH0 as the linear conversion minimum value. Any value within the valid
range can be configured.

When an alarm turns from on to off and vice versa, the span between on and off is called alarm hysteresis. If
the alarm hysteresis is narrowed, the alarm output switches to on or off even by a slight variation of
temperature at around the alarm action point. This frequent on/off of an alarm may negatively affect the
connected equipment. To prevent that harmful effect, configure the alarm hysteresis for alarm on/off action.

The alarm is not triggered until the configured time elapses after the process variable (PV) enters the alarm

by configuring the alarm delay time. When an alarm output is changed from on to off status, the alarm output
turns off and the alarm action delay time is reset. When the alarm output is changed from off to on status, the
time counting starts.

If the sensor cannot be installed to the location of the control target, the temperature measured by the sensor
may deviate from the actual temperature of the control target. When a target is controlled with multiple PID

The process variable (PV) after PV correction can be calculated using the following formula.
Process variable (PV) after PV correction = Process variable (PV) + (PV correction value)

(3) Control Register +63: PV Filter Time Constant

The PV filter function is a software filter to stabilize the process variable (PV) affected by fluctuating processes
such as pressure or flow rate by calculating first-order lag of the process variable (PV). Even if the process

Configure the linear conversion maximum value for the external SP input. When input type is current (4 to

voltage (0 to 1V DC or 1 to 5V DC), configure the value corresponding to 1V or 5V for input CH1.

Example: When input type is current (4 to 20mA DC), if the external SP input linear conversion maximum value
is 1000°C, external SP input 20mA corresponds to the set point (SP) 1000°C for CH0 control. When input type
is voltage (0 to 1V DC), if external SP input linear conversion maximum value is 1200°C, external SP input 1V
corresponds to the set point (SP) 1200°C for CH0 control.

(5) Control Register+179: External SP Input Linear Conversion Minimum Value

Configure the linear conversion minimum value for the external SP input. When input type is current (4 to
20mA DC or 0 to 20mA DC), configure the value corresponding to 4mA or 0mA for input CH1. When input type
is voltage (0 to 1V DC or 1 to 5V DC), configure the value corresponding to 0V or 1V for input CH1.

Example: When input type is current (4 to 20mA DC), if external SP input linear conversion minimum value is
0°C, external SP input 4mA corresponds to the set point (SP) 0°C for CH0 control. When input type is voltage
(0 to 1V DC), if external SP input linear conversion maximum value is set to -20°C, external SP input 0V
corresponds to the set point (SP) -20°C for CH0 control.

(6) Control Register+177: External SP Input Bias

The external SP input bias is added to the set point (SP) obtained after the linear conversion for the external
SP input. The set point (SP) is then used as the set point (SP) for CH0 control.

Examples:
When the input type is current (4 to 20mA DC), the linear conversion maximum value is 1000°C, the linear
conversion minimum value is 0°C, and the external SP input bias is 50°C, the set point (SP) of CH0 control
corresponding to 12mA of external SP input will be 550°C.

When the input type is voltage (0 to 1V DC), the linear conversion maximum value is 1000°C, the linear
conversion minimum value is 0°C, and the external SP input bias is 50°C, the set point (SP) of CH0 control

When an alarm turns from on to off and vice versa, the span between on and off is called alarm hysteresis. If
the alarm hysteresis is narrowed, the alarm output switches to on or off even by a slight variation of
temperature at around the alarm action point. This frequent on/off of an alarm may negatively affect the
connected equipment. To prevent that harmful effect, configure the alarm hysteresis for alarm on/off action.

The alarm is not triggered until the configured time elapses after the process variable (PV) enters the alarm
output range. The input fluctuation due to noise may result in alarm output turning on. This can be prevented
by configuring the alarm delay time. When an alarm output is changed from on to off status, the alarm output
turns off and the alarm action delay time is reset. When the alarm output is changed from off to on status, the
time counting starts.

PID Module Configuration - Control Parameters Details

Control Parameters when Program Control Mode Is Selected

Control parameters of CH0 control are described here. When the program control mode is selected as the
control mode, parameters for the fixed value control mode, such as the set point (SP), proportional
band/proportional gain, or integral time, are disabled. The parameters for the program control mode (23) to
(27) are enabled.
Control parameters for CH1 control are the same as those of CH0 control except cascade control parameters.
However, the position from the control register for each parameter differs. For details about the positions from
the control register for CH1 control, see pages 5-17 to 5-20.

(1) Control Register+90: Control Mode

Either fixed value control mode or program control mode can be selected. When the external SP input or the
cascade control is selected in Input CH1 Function, the program control mode cannot be used for CH0 control.
Select fixed value control mode for control mode of CH0 control. If the program control mode is selected, the
external SP input does not function.

The fixed value control is a normal temperature control that the PID module controls the output to eliminate the
deviation between a single set point (SP) and the process variable (PV). The following diagram shows an
example of the fixed value control.

The program control allows you to define the set point (SP) that changes as the time progresses so that the
process variable (PV) can be controlled to match the set point (SP) changing as the time progresses. The set
point (SP) and time can be configured for each step. A maximum of 10 steps can be configured and performed.
The set point (SP) can be configured as shown in the following diagram.

(2) Control Register+53: Control Action

Selects either direct control action or reverse control action.

In direct control action, the output manipulated variable (MV) increases when the process variable (PV) is
higher than the set point (SP) (positive deviation). For example, freezers perform the direct control (cooling)
action.

In reverse control action, the output manipulated variable (MV) increases when the process variable (PV) is
lower than the set point (SP) (negative deviation). For example, electric furnaces perform the reverse control
(heating) action.
