Ref.1.1(1) Correcting the PV (1. Using PV input filter and PV input bias)

Filtering and biasing functions are available with all the UT/UP series models.

■ PV input filtering can be used to remove noise from a PV input that contains high frequency noise,

such as flow rate and pressure signals.

The PV input filter provides first-order-lag computation. Setting a larger time constant (as a parameter value) can increase the amount of noise removed. This filtering is also used to improve controllability and for phase compensation. The time constant of the PV filter is offered as an operating parameter and can be changed during operation.

IM 05J01B02-01E 5th Edition : Mar.25,2005-00

Ref. 1-2

■ PV input biasing adds a constant bias value to the PV input value, and the result is used for the

controller display and control computation.

PV input value PV value inside the controllerPV input bias

In some cases, the measured value is smaller than the actual value by a constant amount due to the physical circumstances at the sensor point. For example, the ambient temperature inside a furnace is often measured instead of the material’s temperature. In such cases, add a constant value for biasing. When the PV value is within the allowable accuracy range but there is a dispersion in PV readings between other equipment, it is possible to use this function for fine adjustment.

Here we explain how to display the parameter setting display and to change the parameter values. Before carrying out these operations be sure to refer to the User’s Manuals Initial Settings and Parameter Map of the controller. The parameter map is very helpful in finding the path to the setting display for a particular parameter.

1: Referring to the User’s Manual above, display

the operating parameter main menu [LP1] (Note1). Then, display the submenu [P AR].

Note1: If the UP/UT mode has been set for using loop-2 or the

secondary loop, also set the corresponding parameters under the main menu [LP2] in the same way.

2: Press the

SET/ENT

key 3 times* to display the PV input bias parameter BS. * Depends on the controller mode. Pressing the

SET/ENT

key one more time displays

the PV input filter parameter FL.

3: In each of these parameter setting displays,

■ Ten-segment Linearizer Biasing

This function is used to correct an input signal affected by sensor deterioration. The corrected values (b) are obtained by adding the corresponding bias values to each of the 1 1 points of optionally set input values (a). The input values used to configure the ten-segment linearizer are set with parameters 1.a1 to 1.a1 1 (Note). The bias values (b-axis) for each of the input values (a) are set with parameters 1.b1 to 1.b1 1 (Note).

Note: • 1.a1 to 1.a11 and 1.b1 to 1.b1 1 are the parameters for UP750, UP550, and UT750.

• 1.A1 to 1.AB and 1.B1 to 1.BB are the parameters for UT550, UT551 and UT520.

• If the UP/UT mode is set for using loop-2 or the secondary loop, “2.a1 to 2.a11 and 2.b1 to 2.b11,” and “2.A1 to 2.AB and 2.B1 to

2.BB” can also be used.

■ Ten-segment Linearizer Approximation

This function is used when the input signal and the required measurement signal have a non-linear relationship. For example, when trying to obtain the volume from a sphere tank level. As shown in the figure below, the output values (b) can be optionally set to 11 points of the optionally set input values (a). The input values used to configure the ten-segment linearizer are set with parameters 1.a1 to 1.a1 1 (Note). The corrective values (b-axis) of ten-segment linearizer approximation for each of the input values (a) are set with parameters 1.b1 to 1.b1 1 (Note).

Note: • 1.a1 to 1.a11 and 1.b1 to 1.b1 1 are the parameters for UP750, UP550, and UT750.

• 1.A1 to 1.AB and 1.B1 to 1.BB are the parameters for UT550, UT551 and UT520.

• If the UP/UT mode is set for using loop-2 or the secondary loop, “2.a1 to 2.a11 and 2.b1 to 2.b11” and “2.A1 to 2.AB and 2.B1 to 2.BB” can also be used.

Ref.1.1(4) Changing the PV sampling period

CAUTION

When the controller is shipped, the PV sampling period is already set to values suitable for implementing the model’s functions and specifications. Therefore, under normal conditions, the default sampling period should be used with the controller and changing it to a shorter one may disable some of the controller’s functions. The sampling period should only be changed if you fully understand the procedures described in the following section.

CAUTION

The response time in communication may be longer when change the PV sampling period shorter. In this case, reset the PV sampling period longer.

The PV sampling period can be changed with UP750, UP550, UT750, UT550, UT551 and UT520.

Ref.1.1(5) Checking that the changed PV sampling period is appropriate

CAUTION

When you have changed the PV sampling period according to “Ref. 1.1 (4) Changing the PV sampling period” in this section, be sure to check that the new period is appropriate by referring to the following descriptions.

It is necessary to check the new period with UP750, UP550, UT750, UT550, UT551 and UT520 after the PV sampling period has been changed.

It is possible to check whether or not the currently set PV sampling period is appropriate for the controller to perform its required functions. For example, with UT550, the PV sampling period can be selected from 4 periods as shown in Table 1-1-1. However, some of the controller functions will be restricted under the use of each period. Although these limitations are given as “Limitations of controller functions” in “Ref. 1.1 (4) Changing the PV sampling period”, they should be taken only as rough guides. Therefore, you must check whether or not the period is appropriate before you use the controller.Carry out this check at the time of the operation test of the system that uses the controller.

This check is performed by monitoring the sampling error counter. The counter value shows how many times the controller failed to process its operation at the current PV sampling period.(The controller increments the counter value by 1 per 10 ms of control period delay when it cannot execute all the processing within the specified period.)

PV sampling period

Processing

This chart shows that processing cannot be executed within the specified sampling period. In this example, the processing is delayed by 30 ms so the sampling error counter is incremented by 3.

Fig. 1-1-5 PV Sampling Period

Processing Processing

30ms

If the counter value is not “0,” it means that some of the processing of the controller remains unprocessed. For this reason, if an exact control is required, set the sampling period so that the counter value will not increase unless a long time has elapsed. If the counter value increases in a short period of time, change the sampling period to a larger value. Y ou can monitor the counter value through the display of setup parameter SMEC (or SMC for UT5) as shown in the following.

1.1 (1) Correcting the PV (1. Using PV filter and PV bias)” of this section. To use the PV filter and PV bias, operating parameters FL and BS are used. As they are operating parameters, their settings can be changed during operation. Therefore, it is recommended that under normal circumstances you use FL and BS. As for “analog input bias” and “analog input filter ,” read the following description and only set them if necessary .

Sensor input value correction is available with UP750, UP550, UT750, UT550, UT551 and UT520. Analog input bias is used to correct sensor-input characteristics, compensating lead wire errors, and so on.

Normally , the PV biasing (BS) is convenient as mentioned in the CAUTION above, however, use the analog input bias (A.BS) in cases where a constant correction is required due to sensor deterioration or for other reasons. Since this biasing is set using a setup parameter , it is suitable for input correction where once the parameter is set, it will not be changed for a long time.

The analog input filter is used to remove noise from a PV input signal that contains high frequency noise such as flow rate and pressure signals. This filter provides a first-order-lag calculation, which can remove more noise the larger the time constant becomes (see the figure below). However, an excessively large time constant will distort the waveform. (See the figure below) As mentioned in the CAUTION above, a similar effect can be obtained by using the PV filter (FL). However, an analog input filter should be used in the cases where a constant level of correction is required, such as in an environment that contains a lot of noise.

Ref.1.1(7) Using PV tracking function (UT only)

The PV tracking function is available with UT750, UT550, UT551. UT520, UT450, and UT420. PV tracking is used to prevent a sudden change in PV .

Note: As shown below, PV tracking is turned OFF at the time of shipment. T urn it ON if necessary.

When PV tracking is ON, the controller sets the SP equal to PV temporarily in the event of the following:

• Power-on

• Switching from MAN to AUTO mode

• Switching from STOP to RUN

• Switching the number of setpoint (SP No.)

After SP is equalized to PV, the SP is gradually changed toward the original SP value at a constant rate-of-change (for ramp rate; see the CAUTION below and the following Fig. 1-1-7).

CAUTION

The SP rate-of-change (ramp rate) is set using parameter UPR and/or DNR, which is set to OFF at the time of shipment. To use PV tracking, you must set parameter UPR and/or DNR to a desired ramp rate value. → See “Ref.4.1(4) Changing SP at a ramp rate when SP is switched” in Ref. 4-1: References Related to Target Setpoint (SP). With these parameters OFF, which specifies no ramp rate (ramp rate = 0), PV tracking will not operate.

Setting Example (1) For UT750 and UT5

The example below shows signal type, units, range and scaling setpoints used for remote input with the UT750, UT550, UT551 and UT520. For example, with analog input-3 (IN3) = 41, the remote input range is 1.000 to 5.000 for standard signals (1 to 5 V). Here, for an input range of 2 to 4 V , set as follows.

Maximum value of analog input-3 range (RH3) = 4,000 (Ref.: “3,500” means 3.5 V.) Minimum value of analog input-3 range (RL3) = 2,000

Step1: This example shows a remote input range of 1.000 to 5.000 for standard signals

Step2: In this example, the remote input range is set as 2.000 to 4.000V using the parameters

RL3 and RH3.

Step3: With the UT750/UT5 the same units and decimal point position set for the PV

input range are used for the remote input range. For this reason, if the PV input range is set to a thermocouple type K ( -270.0 to 1370.0 C) the initial value of SL3 is set to “-270.0” and that of SH3 is set to “1370.0” .

Step4: Change the initial settings of SDP3,SL3 and SH3 to the actual values for the remote

Input range. In this example, the SDP3 is set to “2” and SL3 is set to “10.00” and the SH3 is set to “50.00”.

Setting Example (2) For UT40

The example below shows signal type, units, range and scaling setpoints used for remote input with the UT40. For example, with remote input type (RSP) = 41, the remote input range is 1.000 to 5.000 for standard signals (1 to 5 V).

Note: Unlike the UT750 and UT5, the UT40 does not have RH3 and RL3 parameters, therefore input signal range cannot be changed.

T o change the input voltage signal (1 to 5 V in this case) to the physical unit of the actual controlled condition (hereinafter, “scaling”), see the Setting Scaling Procedure.

Ref.1.2(4) Tracking target setpoint when switching from remote to local control

Setpoint can be tracked with UT750, UT5 and UT40 controllers that have auxiliary analog input capabilities. This function equalizes the local setpoint to the remote setpoint when switching from remote to local control. This prevents any sudden change in setpoint when control is switched from remote to local.

Setpoint tracking functions as follows.

 Setpoint tracking ON

Regardless of any preset local setpoints, the remote setpoint is used as the local setpoint when control is switched from remote to local. To use the preset local setpoint, punch in the setpoint from the keys.

Ref.2.1(1) Switching between Direct and Reverse Actions

Switching between direct and reverse actions is possible with all models* in the UP and UT series of controllers. (*UP750, UP550, UP35, UT750, UT5, UT40 and UT3)

The terms direct action and reverse action define the directions in which the control output changes to increase or decrease its value according to whether the deviation of a measured value (PV) from the target setpoint (SP) is positive or negative. The controller increases or decreases its control output value in the predetermined mode, either direct action or reverse action, in conjunction with the deviation of the current PV value from the SP value. Note that there are no direct/reverse action options for heating/cooling control.

Y ou can switch between direct and reverse actions even when the controller is in operation. To switch, use the parameter appropriate for your controller model, as noted below.

•“n.DR” operating parameter for the UP750, UP550, UT750, UT5 and UT40

• DR operating parameter for the UP35 and UT3

In the reverse action mode (factory-set default), the control output value decreases if the PV value is greater than the SP value. Inversely , it increases if the PV value is smaller than the SP value (see Fig. 2-1-1 below).

Ref.2.1(2) Selecting PID Control Mode According to the Operating Condition

- Determining whether or not a change in the target setpoint involves control output bump

With UP and UT series controllers, you can select between two types of PID control modes. These control modes are referred to as the standard PID control mode and fixed-point control mode.

For each of these PID control modes, select either the PV derivative type PID control method or deviation derivative type PID control method to carry out control according to the operating condition (mode). You can also select from the Yes/No options for a control output bump at the moment of change in the SP value. (See Table 2-1-2 or 2-1-3 depending on your controller model.)

Note that there is a slight difference in this information between the UP750, UP550, UT750, UT5 and UT40 group of controllers and the UP35 and UT3 group controllers. This section discusses the former group first and then the latter group. See either reference topic according to your controller model.

Control Method Description of Control Action PV derivative type

PID control Control output bump is

allowed during change in SP value.

Deviation derivative type PID control

PV derivative type PID control

Control output bump is not allowed during change in SP value.

The PV derivative type PID control mode is adopted so that the controller can reach the new SP value without delay when the current SP value is changed. In this control mode, the controller immediately outputs the value of the proportional term P which is proportional to the deviation resulting from a change in the SP value. The controller thus attempts to reach the new SP value as soon as possible.

The deviation derivative type PID control mode is adopted in order to improve the follow-up capability of UP series program controllers for marginal variations in the SP value of a program pattern. By allowing the derivative term D to positively act upon variations resulting from a marginal change in the program pattern, the controller keeps track of the pattern without delay.

Use this control method in order to protect the PV value from any disorder that may result when the control output (MV) reacts over-sensitively against a change in the SP value during continuous fixed-point control. If the PV derivative type PID control mode is used with the permitted control output bump, the MV value does not change suddenly during a change in the SP value. The controller uses the integral term I only and gradually eliminates the deviation that has occurred.

For the UT750, the mode is defined by setting as MOD = 1.

PV derivative type PID control

Control output bump is allowed during change in SP value.

Use this control method when using the controller for the secondary loop of cascade control. In this method, the control output never reacts over-sensitively against a change in the primary-loop output. Rather, it delivers stable control output.

Ref.2.1(5) Using “Super” (Overshoot Prevention) Function

The “Super” (overshoot prevention) function is available with the UP750, UP550, UP350, UT750, UT5, UT40 and UT3. This function works when you set the “Super” code SC to 1. It does not work if you set the code to OFF. If the code is set to OFF, the controller operates in the regular PID control mode. (The code is set to OFF when the controller is shipped from the factory .) If you set the code to 2 or 3, the “Super2” (hunting prevention) function works. For more information on the “Super2” functions, see Ref. 2.1 (6).

CAUTION

The SUPER function can only be used with the PID function. If both the integral time and derivative time are set to OFF, the SUPER function will not operate even when SC is set to 1.

The SUPER function operates under the condition that P, I, and D are set up. It is therefore more ef ficient to set the SUPER code (SC) to 1 after auto-tuning is carried out.

The SUPER function is an overshoot-suppressing function that uses fuzzy inference. This function is highly effective when used together with the auto-tuning function in the event of the following.

• Overshoots must be suppressed.

• Rise-up time needs to be shortened.

• Load varies often.

• SP is changed frequently.

When the SUPER function is set on, the controller monitors deviation in order to detect the possibility of an overshoot. When the possibility of overshoot is detected, the controller changes the target setpoint to a tentative value as a secondary setpoint (auxiliary setpoint SSP) and continued control. Then, when the possibility of an over shoot no longer exists, the target setpoint is gradually reset to its original value.

The “Super2” (hunting prevention) function is available with the UP750, UP550, UP350, UT750, UT5, UT40 and UT3. This function works when you set the “Super” code SC to either 2 or 3. It does not work if you set the code to OFF. If the code is set to OFF, the controller operates in the regular PID control mode. (The code is set to OFF when the controller is shipped from the factory .) If you set the code to 1, the “Super” (overshoot prevention) function works. For more information on the “Super” functions, see Ref. 2.1 (5).

CAUTION

• Use “Super2” only for PID or PI control. The function does not work in any of the following control modes. On-off control, P control (control using the proportional band term only), PD control (control using the proportional band and derivative terms only), and heating/cooling control.

• Do not use the “Super 2” function for the fast-response process such as flowrate or pressure control.

If you will use the “Super2” function for PID control, also use auto-tuning together with the function to maximize the function’s capability . After auto-tuning, set the “Super” code SC to either 2 or 3.

“Super2” is effective when used in the following cases.

The “Super2” function is designed to prevent hunting by means of a phase compensation block built in the PID computation block (see Fig. 2-1-4 below).

“Super2” is effective when used in the following cases.

• There is a frequent change in the load.

• The controller is exposed to a high degree of disturbance and takes time to settle to normal.

• Even if the PID constants are correctly set, hunting remains when the SP value is changed.

The “Super2” hunting-preventing function has two modes, as shown in Table 2.1.5. Y ou can select either of them by setting the SC parameter accordingly .

Ref.2.1(9) Placing Control Output in Tracking Mode (for Cascade Primary-loop Control

or Loop Control for Backup)

Placing the control output in tracking mode is possible with the UP750, UP550, UT750, UT550, UT551 and UT520.

As noted in the heading above, this feature works only when the controller is used for cascade primary-loop control or loop control for backup (though the UP750 and UP550 do not support loop control for backup).

Output tracking is a function with which switching is carried out between an external tracking input signal and the control output signal of the controller by means of a contact input or communication. The output tracking function works only when the controller is in either of the two control modes discussed above. Fig. 2-1-8 briefly illustrates how this function works.

Ref.2.1(10) Using Shutdown Function

Using the shutdown function is possible with the UP750, UP550, UT750, UT550, UT551 and UT520. The shutdown function is designed to fully close a control valve (forcibly zeroes the output) by sending a signal level beyond the limit of the dead band of the positioner of the valve. This function is enabled by setting the output limiter’s lower limit (n.OL [n = 1 to 8] parameter) to the option “SD” when the controller is set to current output signal and in manual mode.

• When in automatic mode operation The output limiter’s lower limit is set at -5.0% and is not lowered to 0.0 mA.

• When in manual mode operation The control output delivers a shutdown signal (approximately 0.0 mA) when decreased to the setpoint SD with the

Ref.2.2(2) Retransmitting Program Pattern 2 (for UP750/UP550 only)

CAUTION

The UP750 and UP550 can retransmit program pattern 2 as explained below, though this is not possible with the following controller modes (UP modes) of these controllers.

• UP750: Cascade control, dual-loop control, temperature and humidity control, cascade control with universal input

• UP550: Cascade control

The UP750 and UP550 can retransmit program pattern 2 that is set for running on loop 2. For this reason, they can also serve as program generators. Both controllers can retransmit program pattern 2 at the same time when they are running their own program patterns.

TIP

The “PT2.G” parameter designed for this function is called the “Program Pattern 2 Retransmission” parameter, because it retransmits a program pattern used for loop 2.

T o retransmit program pattern 2, the “ RET1” and “RET2” setup parameters discussed in the previous section and the “PT2.G” parameter related to target setpoints are used. The terminals used for retransmission dif fer depending on which of the “RET1” or “RET2” parameters you select; therefore, you should also be careful with terminal wiring. Furthermore, exercise care not to use these terminals for control output.

Follow the steps below to configure these parameters:

[1] Set the “PT2.G” parameter to “ON”. [2] Set either the “RET1” or “RET2” parameter to “6”.

As discussed earlier, the setting value “6 ” is used to select the target setpoint-2 (SP2) retransmission output.

This completes parameter setting. Program pattern retransmission will begin at the same time when the controller goes into program operation.

Ref.2.2(3) Using the Loop Power Supply Function

CAUTION

The loop power supply is available in two voltage levels.

(1) The 14.5 to 18.0V DC (21 mA DC) voltage level is the standard loop power supply for all controller

models. This standard feature becomes available when you specify the type of retransmission output. See the explanation given below.

(2) The 21.6 to 28.0V DC (30 mA max.) voltage level is added to your controller as an option if specified (by

the option code) at the time of ordering. This optional feature is assigned to specific terminals prior to delivery . Therefore, you can use the feature directly without having to select a type of retransmission output as explained below.

[1]Using the Standard Loop Power Supply

As discussed in “Ref. 2.2 (1) Changing the Type of Retransmission Output” earlier in this section, set the relevant parameter (see the table below) to “4” in order to use the standard loop power supply.

[2]About the Loop Power Supply Function

The loop power supply function supplies DC power to instruments, such as a two-wire transmitter. The loop power supply block is isolated from the controller’s internal circuitry. In addition, the block is equipped with a currentlimiting circuit. Therefore, accidental short-circuits that may occur in the field do not adversely affect the rest of the controller’s internal circuitry. Note that the loop power supply function cannot be used for digital communication where the supply voltage is superposed on the signal line.

As explained earlier, there are two types of loop power supply: the standard and optional power supplies. Use either of them according to your application needs.

Specifications of Loop Power Supply Standard supply 14.5 to 18.0V DC (21 mA DC) Optional supply 21.6 to 28.0V DC (30 mA DC max.)

CAUTION

The contact input functions of a UT/UP series controller are pre-assigned to their respective input terminals when the controller is shipped from the factory . The function assignments in each of the UT/UP modes are defined in terms of the most frequently used. Check the controller model you will use and the factory-set terminal assignments for each controller mode of the model. Changes should only be made if you require any of the functions listed below or need to change any of the terminal numbers. If you change any of the contact input terminal assignments, check that the new assignment agrees with the current wiring. If necessary, rewire the terminals.

This section contains reference information on the following aspects of contact input functions. Refer to this information and change parameter settings only if necessary .

Ref.3.1(1) Changing contact input functions for the UT35/UT32

Each UT35 and UT32 comes with three contact input terminals that can be used, for example, to change the operation mode. When the controller is shipped from the factory , the terminals are set to the functions between target setpoints 1 and 2” and “switching between the auto and manual modes.”

The terminal numbers are 18, 19 and 20 (common terminals). Terminal 18 is assigned as DI1 (for contact input 1) and terminal 19 as DI2 (for contact input 2). (See the terminal wiring diagrams in the Installation user’s manual.)

Note1: The “I Relay” numbers used here are 161 to 168. DI numbers for contact input terminals are specified by these “I Relay” numbers each

of which is incremented by 5000. For more information on “I Relay” numbers, see Ref. 8.1(4). The relationship between the factory-set DI numbers and input terminal assignments may differ depending on the UT mode of your controller. Always refer to the terminal wiring diagrams in the Installation user’s manual to verify the factory-set terminal assignments of each UT mode.

The UT750 is designed so that functions assigned to its contact input terminals can be changed. In addition, functions can be assigned to the terminals of an optional I/O expansion module. Select the desired contact input terminal with which a function predefined for each setup parameter (contact input registration parameter) is executed. To do this, register the “I Relay” number corresponding to the terminal’ s DI number with the setup parameter whose you want to see. Use the following parameter map to reassign terminal functions as necessary .

CAUTION

If you change any of the contact input terminal assignments, check that the new assignment agrees with the current wiring. If necessary , rewire the terminals.

(4-2): Using contact I/O expansion module with the UT750

The UT750 comes with eight contact input terminals (including one common terminal): terminals 18, 19, 20 (common terminal), 36, 37, 38, 39 and 40. If these do not suffice your needs, using I/O expansion modules increase the number of available contact inputs to a maximum of 23 (Note1). Up to two expansion modules can be installed at a time. Each has eight contact inputs and eight contact outputs. Therefore, connecting two modules to the controller, provides a total of 23 inputs, 16 (8 x 2) inputs from the two modules and 7 standard inputs from the controller (actually there are only seven standard inputs available because terminal 20 of the above-mentioned eight terminals is reserved as a common terminals.)

Note1: Requires Yokogawa’s optional add-on module for the µF A40 compact program controller.

The relationship between the contact input terminals of an I/O expansion module and the I Relay numbers is given in the table below. To assign contact-switched functions to the module’s terminals, follow the steps below.

1) Select a contact-switched function to assign to a module terminal from the table of setup parameters (contact input registration parameters) in (4-1).

2) Select a terminal from those of the I/O expansion module listed in the table below.

(4-3): Using Interrupt-message functions with the UT750

The UT750 is designed so that you can display one of up to four user-registered messages on a setting display using signals from contact input terminals. Messages must be no longer than 20 single-byte alphanumeric characters. This feature is convenient, as it automatically displays a message specific to an event that occurs during operation.

CAUTION

The optional communication function or the optional LL100 Parameters Setting Tool is required to register these messages (each comprising no more than 20 alphanumeric characters).

The text strings of messages must be registered with the UT750’s D-registers (numbered 801 to 840) in advance. Up to four messages can be registered. Register each message with its specifically numbered D-register, as shown below. For more information on how to register messages, see the user’s manual of the communication function or the LL100 Parameters Setting Tool.

Register numbers for registering message 1 (MG1): D0801 to D0810 Register numbers for registering message 2 (MG2): D0811 to D0820 Register numbers for registering message 3 (MG3): D0821 to D0830 Register numbers for registering message 4 (MG4): D0831 to D0840

Messages are displayed in the following way . A message appears when the controller is showing an operating display and the status of the contact input terminal where the message is registered changes from OFF to ON. The four (maximum) messages correspond to the setup parameters “MG1” to “MG4”. For example, if the message text registered with the “MG1” is “POWER DOWN”, and for some reason the status of the assigned contact changes from OFF to ON, the message “POWER DOWN” appears on the display . This contact is selected by registering the “I-Relay” number (with an increment of 5000) that corresponds to the DI number of the contact terminal as the “MG1” setting, as explained earlier (see Table 3-1-7).

For example, if you use terminals

and 20, as shown in the Fig. 3-1-7, register “5161” (the “I-Relay” number of

DI1 plus 5000) as the “MG1” setting. Pressing the [DISP] key on the UT750’s front panel clears the message from display. Showing an operating

parameter setting display (by holding down the

SET/ENT

key for more than 3 seconds) on the display also clears the

message.

• Specify the contact input terminal, where a change in status from OFF to ON is made to show message 1, as the “MG1” setting. For example, If you use terminals 19 and 20 , as shown in the figure on the left, register “5161” (the “I Relay” number of DI1 plus

(4-4): Using Interrupt-operating display functions with the UT750

The UT750 is designed so that you can display the expected operating display using signals from contact input terminals. This feature is convenient, as it automatically displays the expected operating display specific to an event that occurs during operation.

CAUTION

The optional LL 200 custom computation building tool is required to use this function. Refer to the User’s manual of LL200 for more details.

The expected operating display appears when the status of the contact input terminal where the operating display is registered changes from OFF to ON. The operating display correspond to the setup parameters “DP1” or “DP2”. This contact is selected by registering the “I-Relay” number (with an increment of 5000) that corresponds to the DI number of the contact terminal as the “DP1” or “DP2” setting, as explained earlier (see Table 3-1-7).

Pressing the [DISP] key on the UT750’s front panel displays the next operating display.

(7-2): Using contact I/O expansion module with the UP750

The UP750 comes with eight contact input terminals (including one common terminal): terminals 18, 19, 20 (common terminal), 36, 37, 38, 39 and 40. If these do not suffice your needs, using I/O expansion modules increase the number of available contact inputs to a maximum of 23 (Note1). Up to two expansion modules can be installed at a time. Each has eight contact inputs and eight contact outputs. Therefore, connecting two modules to the controller, provides a total of 23 inputs, 16 (8 x 2) inputs from the two modules and 7 standard inputs from the controller (actually there are only seven standard inputs available because terminal 20 of the above-mentioned eight terminals is reserved as a common terminals.)

Note1: Requires Yokogawa’s optional add-on module for the µF A20 compact program controller.

(7-3): Using Interrupt-message functions with the UP750

The UP750 is designed so that you can display one of up to four user-registered messages on a setting display using signals from contact input terminals. Messages must be no longer than 20 single-byte alphanumeric characters. This feature is convenient, as it automatically displays a message specific to an event that occurs during operation.

CAUTION

The optional communication function or the optional LL100 Parameters Setting Tool is required to register these messages (each comprising no more than 20 alphanumeric characters).

The text strings of messages must be registered with the UP750’s D-registers (numbered 801 to 840) in advance. Up to four messages can be registered. Register each message with its specifically numbered D-register, as shown below. For more information on how to register messages, see the user’s manual of the communication function or the LL100 Parameters Setting Tool.

IM 05J01B02-01E 5th Edition : Mar.25,2005-00

Ref. 3-37

For example, if you use terminals

and 20, as shown in the Fig. 3-1-12, register “5161” (the “I-Relay” number of

DI1 plus 5000) as the “MG1” setting. Pressing the [DISP] key on the UP750’s front panel clears the message from display . Showing an operating

parameter setting display (by holding down the

SET/ENT

key for more than 3 seconds) on the display also clears the

message.

The setting range equals the range of “I Relay” numbers (each number plus 5000) that correspond to the DI numbers of the contact input terminals you want to use. (Note1)

interruption-4 (Note1)

Note1: The “I Relay” numbers used here are 161 to 168. When the I/O expansion module is used, the numbers 177 to 192 are also the

applicable “I Relay” numbers. For more information on “I Relay” numbers, see Ref. 8.1(4). The relationship between the factory-set DI numbers and input terminal assignments may differ depending on the UP mode of your controller. Always refer to the terminal wiring diagrams in the Installation user’s manual to verify the factory-set terminal assignments of each UP mode.
