2. HANDLING CAUTIONS

 FNICO Rules

The FNICO Concept allows the interconnection of nonincendive field wiring apparatus to associated nonincendive field wiring apparatus not specifically examined in such combination. The criterion for such interconnection is that the voltage (Vmax), the current (Imax) and the power (Pmax) which nonincendive field wiring apparatus can receive and remain nonincendive, considering faults, must be equal or greater than the voltage (Uo, Voc or Vt), the current (Io, Isc or It) and the power (Po) which can be provided by the associated nonincendive field wiring apparatus (supply unit). In addition the maximum unprotected residual capacitance (Ci) and inductance (Li) of each apparatus (other than terminators) connected to the Fieldbus must be less than or equal to 5nF and 10uH respectively.

In each N.I. Fieldbus segment only one active source, normally the associated nonincendive field wiring apparatus, is allowed to provide the necessary power for the Fieldbus system. The allowed voltage (Uo, Voc or Vt) of the associated nonincendive field wiring apparatus used to supply the bus cable must be limited to the range 14Vdc to 17.5Vdc. All other equipment connected to the bus cable has to be passive, meaning that the apparatus is not allowed to provide energy to the system, except a leakage current of 50É A for each connected device. Separately powered equipment needs galvanic isolation to ensure the nonincendive field wiring Fieldbus circuit remains passive.

Cable

The cable used to interconnect the devices needs to comply with the following parameters:

Loop resistance R': 15...150 Ω/km Inductance per unit length L': 0.4...1 mH/km

Capacitance per unit length C': 80....200 nF/km

C' =C' line/line+0.5 C' line/screen, if both lines are floating or C' = C' line/line + C'line/screen, if thescreen is connected to one line. Length of spur cable: max. 30 m Length of trunk cable: max. 1 km Length of splice: max = 1 m

Terminators

At the end of each trunk cable an FM Approved line terminator with the following parameters is suitable:

R= 90...100 Ω

C = 0 ....2.2 uF

3. ABOUT FIELDBUS

3.1 Outline

Fieldbus is a wide l y u se d bi-directional digital communication protocol for field devices that enable the simultaneous output to many types of data to the process control system.

The EJX Series Fieldbus communication type employs the specification standardized by The Fieldbus Foundation, and provides interoperability between Yokogawa devices and those produced by other manufacturers. Fieldbus comes with software consisting of three AI function blocks that enable the flexible implementation of systems.

For information on other features, engineering, design, construction work, startup and maintenance of Fieldbus, refer to “Fieldbus Technical Information” (TI 38K03A01-01E).

3.2 Internal Structure of EJX

The EJX contains two virtual field devices (VFD) that share the following functions.

3.2.1 System/network Management VFD

• Sets node addresses and Physical Device tags (PD Tag) necessary for communication.

• Controls the execution of function blocks.

•Manages operation parameters and communication resources (Virtual Communication Relationship: VCR).

• Carry out scaling, damping and square root extraction.

(5)PID function block

• Performs the PID control computation based on the deviation of the measured value from the setpoint.

4. GETTING STARTED

Fieldbus is fully dependent upon digital communication protocol and differs in operation from conventional 4 to 20 mA transmission and the BRAIN communication protocol. It is recommended that novice users use field devices in accordance with the procedures described in this section. The procedures assume that field devices will be set up on a bench or in an instrument shop.

4.1 Connection of Devices

The following are required for use with Fieldbus devices:

• Power supply:

Fieldbus requires a dedicated power supply. It is recommended that current capacity be well over the total value of the maximum current consumed by all devices (including the host). Conventional DC current cannot be used as is.

• Terminator:

Fieldbus requires two terminators. Refer to the supplier for details of terminators that are attached to the host.

•Field devices:

Connect Fieldbus communication type EJX. Two or more EJX devices or other devices can be connected.

• Host:

Used for accessing field devices. A dedicated host (such as DCS) is used for an instrumentation line while dedicated communication tools are used for experimental purposes. For operation of the host, refer to the instruction manual for each host. No other details on the host are given in this manual.

•Cable:

Used for connecting devices. Refer to “Fieldbus Technical Information” (TI 38K03A01-01E) for details of instrumentation cabling. For laboratory or other experimental use, a twisted pair cable two to three meters in length with a cross section of

0.9 mm2 or more and a cycle period of within 5 cm (2 inches) may be used. Termination processing depends on the type of device being deployed. For EJX, use an M4 screw terminal claw. Some hosts require a connector.

Refer to Yokogawa when making arrangements to purchase the recommended equipment.

Connect the devices as shown in Figure 4.1. Connect the terminators at both ends of the trunk, with a minimum length of the spur laid for connection.

The polarity of signal and power must be maintained.

NOTE

No CHECK terminal is used for Fieldbus communication EJX. Do not connect the field indicator and check meter.

Before using a Fieldbus configuration tool other than the existing host, confirm it does not affect the loop functionality in which all devices are already installed in operation. Disconnect the relevant control loop from the bus if necessary.

IMPORTANT

Connecting a Fieldbus configuration tool to a loop with its existing host may cause communication data scrambling resulting in a functional disorder or a system failure.

4.2 Host Setting

To activate Fieldbus, the following settings are required for the host.

IMPORTANT

Do not turn off the power immediately after setting. When the parameters are saved to the EEPROM, the redundant processing is executed for an improvement of reliability. If the power is turned off within 60 seconds after setting is made, the modified parameters are not saved and the settings may return to the original values.

4.4 Integration of DD

If the host supports DD (Device Description), the DD of the EJX needs to be installed. Check if host has the following directory under its default DD directory.

594543\000C

(594543 is the manufacturer number of Yokogawa Electric Corporation, and 000C is the EJX device

number, respectively.) If this directory is not found, the DD of the EJX has not been included. Create the above directory and copy the DD file (0m0n.ffo, 0m0n.sym) (m, n is a numeral) into the directory. ‘0m’ in the file name shows the device revision, and ‘0n’ shows the DD revision. If you do not have the DD or capabilities files, you can download them from our web site:

http://www.yokogawa.com/fld Once the DD is installed in the directory, the name and

attribute of all parameters of the EJX are displayed. Off-line configuration is possible by using capabilities

files. EJX has two capabilities levels, “1” and “2”.

(6)Block setting

Sets the parameters for function blocks.

The following section describes in sequence each step of this procedure. The use of a dedicated configuration tool significantly simplifies this procedure. Refer to Appendix 6 when the EJX is used as Link Master.

• Terminator

Fieldbus requires two terminators. Refer to the

supplier for details of terminators that are attached

to the host.

•Field devices

Connect the field devices necessary for instrumenta-

tion. The EJX has passed the interoperability test

conducted by The Fieldbus Foundation. In order to

properly start Fieldbus, it is recommended that the

devices used satisfy the requirements of the above

test.

• Host

Used for accessing field devices. A minimum of one

device with the bus control function is needed.

• Cable

Used for connecting devices. Refer to “Fieldbus

Technical Information” for details of instrumenta-

tion cabling. Provide a cable sufficiently long to

connect all devices. For field branch cabling, use

terminal boards or a connection box as required.

First, check the capacity of the power supply. The power supply capacity must be greater than the sum of the maximum current consumed by all devices to be connected to Fieldbus. The maximum current consumed (power supply voltage 9 V to 32 V) for the EJX is 15 mA (24 mA in Software download operation). The cable used for the spur must be of the minimum possible length.

5.1 Network Design

Select the devices to be connected to the Fieldbus network. The following are essential for the operation of Fieldbus.

• Power supply

5.2 Network Definition

Before connection of devices with Fieldbus, define the Fieldbus network. Allocate PD Tag and node addresses to all devices (excluding such passive devices as terminators).

The PD Tag is the same as the conventional one used for the device. Up to 32 alphanumeric characters may be used for definition. Use a hyphen as a delimiter as required.

The node address is used to specify devices for communication purposes. Because this data is too long for a PD Tag, the host uses the node address in place of the PD Tag for communication. A range of 20 to 247 (or hexadecimal 14 to F7) can be set. The device

5. CONFIGURATION

(LM device) with bus control function (Link Master function) is allocated from a smaller address number (20) side, and other devices (BASIC device) without bus control function allocated from a larger address number (247) side respectively. Place the EJX in the range of the BASIC device. When the EJX is used as Link Master, place the EJX in the range of the LM device. Set the range of addresses to be used to the LM device. Set the following parameters.

The devices within the address range written as “Unused” in Figure 5.1 cannot be used on a Fieldbus. For other address ranges, the range is periodically checked to identify when a new device is mounted. Care must be taken to keep the unused device range as narrow as possible so as to lessen the load on the Fieldbus.

To ensure stable operation of Fieldbus, determine the operation parameters and set them to the LM devices. While the parameters in Table 5.2 are to be set, the worst-case value of all the devices to be connected to the same Fieldbus must be used. Refer to the specification of each device for details. Table 5.2 lists EJX specification values.

5.3 Definition of Combining Function Blocks

The input/output parameters for function blocks are combined. As required, they can be combined with the input of the control block. The setting is written to the EJX link object. See “Block setting” in Section 5.6 for the details. It is also possible to read values from the host at proper intervals instead of connecting the EJX block output to other blocks.

The combined blocks need to be executed synchronously with other blocks on the communications schedule. In this case, change the EJX schedule according to the following table. The values in the table are factory-settings.

5. CONFIGURATION

A maximum of 30 ms is taken for execution of AI block. For scheduling of communications for combination with the next function block, the execution is so arranged as to start after a lapse of longer than 30 ms. In no case should function blocks of the EJX be executed at the same time (execution time is overlapped).

Figure 5.3 shows an example of schedule based on the loop shown in Figure 5.2.

5.4 Setting of Tags and Addresses

This section describes the steps in the procedure to set PD Tags and node addresses in the EJX. There are three states of Fieldbus devices as shown in Figure 5.4, and if the state is other than the lowest SM_OPERATIONAL state, no function block is executed. EJX must be transferred to this state when an EJX tag or address is changed.

When the control period (macrocycle) is set to more than 4 seconds, set the following intervals to be more than 1% of the control period.

- Interval between “end of block execution” and “start of sending CD from LAS”

- Interval between “end of block execution” and “start of the next block execution”

EJX has a PD Tag (PT2001) and node address (245, or hexadecimal F5) that are set upon shipment from the factory unless otherwise specified. To change only the node address, clear the address once and then set a new node address. To set the PD Tag, first clear the node address and clear the PD Tag, then set the PD Tag and node address again.

Devices whose node addresses have been cleared will have the default address (randomly chosen from a range of 248 to 251, or from hexadecimal F8 to FB). At the same time, it is necessary to specify the device ID in order to correctly specify the device. The device ID of the EJX is 594543000Cxxxxxxxx. (The xxxxxxxx at the end of the above device ID is a total of 8 alphanumeric characters.)

5. CONFIGURATION

5.5 Communication Setting

To set the communication function, it is necessary to change the database residing in SM-VFD.

5.5.1 VCR Setting

Set VCR (Virtual Communication Relationship), which specifies the called party for communication and resources. EJX has 33 VCRs whose application can be changed, except for the first VCR, which is used for management.

EJX has VCRs of four types: Server(QUB) VCR

A Server responds to requests from a host. This communication needs data exchange. This type of communication is called QUB (Queued Usertriggered Bidirectional) VCR.

Source (QUU) VCR

A Source multicasts alarms or trends to other devices. This type of communication is called QUU (Queued User-triggered Unidirectional) VCR.

Publisher (BNU) VCR

A Publisher multicasts AI block output to another function block(s). This type of communication is called BNU (Buffered Network-triggered Unidirectional) VCR.

Subscriber (BNU) VCR

A Subscriber receives output of another function block(s) by PID block.

A Server VCR is capable to responding to requests from a Client (QUB) VCR after the Client successfully initiates connection to the Server. A Source VCR transmits data without established connection. A Sink (QUU) VCR on another device can receive it if the Sink is configured so. A Publisher VCR transmits data when LAS requests so. An explicit connection is established from Subscriber (BNU) VCR(s) so that a Subscriber knows the format of published data.

Each VCR has the parameters listed in Table 5.4. Parameters must be changed together for each VCR because modification of individual parameters may cause inconsistent operation.

Many parameters require a change of the block mode of the function block to O/S (Out of Service) when their data is changed. To change the block mode of the function block, its MODE_BLK needs to be changed. The MODE_BLK is comprised of the four subparameters below:

IMPORTANT

(1) Target (Target mode):

Sets the operating condition of the block.

(2) Actual (Actual mode):

Indicates the current operating condition.

(3) Permit (Permitted mode):

Indicates the operating condition that the block is allowed to take.

(4) Normal (Normal mode):

Indicates the operating condition that the block will usually take.

6.3 SENSOR T ransducer Block

The SENSOR transducer block is in between the sensor and the AI function blocks. It calculates pressure/differential pressure, static pressure, and capsule temperature from sensor signals. Then it performs damping and range checks for the measured values of these three variables and sends signals to the AI function block.

6.3.1 Functional block

Figure 6.1 presents the functional block of the SENSOR transducer. The calculated values of pressure/ differential pressure, H-side static pressure, L-side static pressure, and capsule temperature are assigned to PRIMARY_VALUE, SECONDARY_VALUE, TERTIARY_VALUE, CAP_TEMP_VAL, and AMP_TEMP_VAL, respectively. Measured values output to the AI function blocks are selected by the Channel parameter of those blocks.

6.3.2 Block Mode

The Block modes permitted for the SENSOR transducer block are Automatic (Auto) and Out of Service (O/S). The mode must be set to Auto under normal operating conditions, and to O/S when making changes to an important parameter. For parameters that can only be changed in the Auto and O/S modes, refer to the parameter list for the SENSOR Transducer block in Chapter 9.

6.3.3 Functions Relating to Pressure/

Differential Pressure

Reference to pressure/differential pressure value:

By accessing PRIMARY_VALUE, it is possible to refer to the pressure/differential pressure value and status. The update period of this value is 100 msec. The pressure unit is selected by XD_SCALE.unit of the AI block, in which PRIMARY_VALUE is selected. The status is normally Good-Non Specific. However, in the case of a sensor failure or out of measurement range, it turns to Bad or Uncertain. For details, refer to Table 8.9.

Setting of signal damping for pressure/differential pressure:

When the pressure/differential pressure signal fluctuates greatly, the fluctuation can be reduced by increasing the time constant for signal damping. PRIMARY_VALUE_FTIME is the parameter for setting the signal damping for pressure/differential pressure. The unit of signal damping is second.

Determination of the range limit of pressure/ differential pressure signal:

When the pressure/differential pressure signal deviates more than 10% from the capsule measurement range shown in PRIMARY_VALUE_RANGE, set the status of PRIMARY_VALUE to Uncertain-Sensor Conversion not Accurate.

Manual adjustment From the exerted pressure and the output of the transmitter, calculate the amount of zero/span adjustment manually, and assign the calculated value to parameters (CAL_DEVIATION_LO, CAL_DEVIATION_HI).

Zero-point adjustment by the external screw. With pressure being exerted on the point where the adjustment is to be made, zero adjustment needs to be performed. To do this, adjust the calculated value by turning the external Zero-point adjustment screw, so that it agrees with the actual input pressure (true value). The output value increases when the screw is rotated to the right. It decreases when the screw is rotated to the left. The adjustment width is small when the rotation speed is low and large when fast.

When performing zero-point adjustment by the external screw, EXTERNAL_ZERO_TRIM needs to be set to “Enable.”

Adjustment of pressure/differential pressure signal:

EJX Series Pressure/Differential Pressure Transmitters have been accurately adjusted according to the specifications at factory setting. Minimal errors can occur due to the environment where the transmitter is installed and the mounting position. To fine-tune any errors, three zero/span adjustment functions can be used: automatic and manual zero/span adjustment by communication terminals, and zero-point adjustment by means of the external adjustment screw on the transmitter.

Automatic adjustment The value of the pressure exerted on the point where the adjustment is to be made is assigned to parameters (CAL_POINT_LO, CAL_POINT_HI). After this assignment is set, the amount of adjustment is calculated by the transmitter and automatically updated.

6-2

IM 01C25T02-01E

6. EXPLANATION OF BASIC ITEMS

Procedure for automatic adjustment The procedure for automatic adjustment is as follows:

(1) Change the Block mode

Set MODE_BLK to O/S.

(2) Enter zero% pressure

Apply the actual zero% pressure to EJX.

(3) Perform zero adjustment

When the value of the applied pressure is written to CAL_POINT_LO, EJX calculates the amount of adjustment for zero adjustment. The calculated amount of adjustment is incorporated into CAL_DEVIATION_LO.

(4) Input pressure for span adjustment

For span adjustment, apply the actual 100% pressure to EJX.

(5) Performance of span adjustment

When the value of the applied pressure is written to CAL_POINT_HI, EJX calculates the amount of adjustment for span adjustment. The calculated amount of adjustment is incorporated into CAL_DEVIATION_HI.

(6) Change the operation mode

Set MODE_BLK to AUTO for normal operation.

CAUTION

Span adjustment is a function for adjusting the gradient with respect to the point of zero adjustment. If that point is not zero, the gradient of input and output values cannot be accurately adjusted. Perform span adjustment after zero adjustment is completed.

Diagnosis of adjustment results:

When the amount of zero adjustment or span adjustment exceeds any of the following adjustment limits, “AL50: Adjustment range error for pressure/differential pressure” is displayed.

The conditions for zero/span adjustment are as follows:

<1> The point of zero adjustment is within ±10%

of the capsule range.

<2> The amount of zero adjustment is within ±10%

of the capsule range.

<3> The point of span adjustment is within the

capsule range.

<4> The input and output gradients after span

adjustment are within ±10% of the gradient at factory setting.

6.3.4 Functions Relating to Static Pressure

The static pressure measurement function is unique to EJX series differential pressure transmitters. The pressure transmitter does not have this function.

Reference to static pressure value:

In SECONDARY_VALUE and TERTIARY_VALUE, it is possible to refer to the H-side static pressure value and the L-side static pressure value, respectively. The update period of these values is 100 msec. The pressure unit is selected by XD_SCALE.unit in the AI block, in which SECONDARY_VALUE and TERTIARY_VALUE are selected. The status is normally Good-Non Specific. However, in the case of a sensor failure or out of measurement range, it turns to Bad or Uncertain. For specifics, refer to Table 8.9.

Setting of signal damping for static pressure:

SP_VALUE_FTIME is parameter that set signal damping for static pressure signals. The unit of the signal damping is second.

Determination of the range limit of static pressure signal:

When the static pressure signal exceeds the maximum working pressure (MWP) of the capsule, set the status of PRIMARY_VALUE to Uncertain-Subnormal. Also, set the status of SECONDARY_VALUE and TERTIARY_VALUE to Uncertain-Sensor Conversion not Accurate. The status under normal conditions is Good-Non Specific.

6-3

IM 01C25T02-01E

6. EXPLANATION OF BASIC ITEMS

Adjustment of static pressure signal:

The zero/span adjustment function can be used for static signals, as in the case of pressure /differential pressure signals. However, the zero-point adjustment by the external screw function is not supported for static pressure signal.

Automatic adjustment The value of the static pressure exerted on the point where adjustment is to be made is assigned to parameters (CAL_SP_POINT_LO, CAL_SP_POINT_HI). After this assignment is set, the amount of adjustment is calculated by the transmitter and automatically updated. The procedure for adjusting the static pressure signal is the same as that of pressure/differential pressure signal.

Manual adjustment From the exerted pressure and the output of the transmitter, calculate the amount of zero/span adjustment manually and assign the calculated value to parameters (CAL_SP_DEVIATION_LO, CAL_SP_DEVIATION_HI).

Selection of static pressure signal type:

EJX series differential pressure transmitters measure the absolute static pressure. Based on the assumption that atmospheric pressure is constant, these transmitters can output signal equivalent to gauge pressure calculated by deducting the atmospheric pressure (fixed value) from the measured absolute pressure. The type of static pressure signal output to SECONDARY_VALUE and TERTIARY_VALUE is selected in SP_VALUE_TYPE. SP_VALUE_TYPE allows selection of gauge pressure or absolute pressure. When selecting gauge pressure, set the value of the atmospheric pressure (fixed value) to ATM_PRESS. The default value of ATM_PRESS is equal to the value of standard atmospheric pressure (101.325 kPa).

6.3.5 Functions Relating to Capsule and Amplifier Temperature

Reference to capsule and amplifier temperature value:

In CAP_TEMP_VAL and AMP_TEMP_VAL, it is possible to refer to the capsule and amplifier temperature value and status. The update period of this value is about 1 sec. The temperature unit is selected by XD_SCALE.unit of the AI block, in which CAP_TEMP_VAL is selected. The status is normally Good-Non Specific. However, in the case of sensor failure or out of measurement range, it turns to Bad or Uncertain. For specifics, refer to Table 8.9.

Determination of the range limit of capsule temperature:

The range of capsule temperature is from –40 to 120 !C. When the measured capsule temperature deviates from –50 to 130 !C range, set the status of CAP_TEMP_VAL to Uncertain-Sensor Conversion not Accurate. The status under normal conditions is GoodNon Specific. Also, set the status of PRIMARY_ VALUE, SECONDARY_VALUE and TERTIARY_ VALUE TO Uncertain-Subnormal.

Determination of the range limit of amplifier temperature:

The range of amplifier temperature is from –40 to 120!C. When the measured amplifier temperature deviates from –50 to 95!C range, set the status of AMP_TEMP_VAL to Uncertain-Sensor Conversion not Accurate. The status under normal conditions is Good-Non Specific.

6.3.6 BLOCK_ERR

BLOCK_ERR presents the cause of an error in the block. The SENSOR transducer block checks the following causes and sets the relevant bits.

6.5 AI Function Block

The AI function block is a unit of the software and executed according to the system schedule. During execution, it incorporates data from the SENSOR transducer block. After execution, it updates analog outputs and processes newly generated alarms. AI function blocks can provide a discrete output which shows the status of LO, LO_LO, HI, or HI_HI. In terms of function, there is no difference between the three AI function blocks provided in EJX.

6.5.1 Function Blocks

The AI function block, via the Channel, incorporates analog signals from the transducer block, performs scaling processing, filtering, low-cut, and alarm processing before outputting. It has the function to generate a discrete output. Figure 6.4 presents the AI function block.

6.5.2 Block Mode

The Block modes permitted for the AI function block are Automatic (Auto), Manual (Man), and Out of Service (O/S). When the Block mode of RB (Resource Block) is Out of Service (O/S), Actual is Out of Service (O/S) even if Automatic (Auto) or Manual (Man) is written to Target.

6.5.4 STATUS_OPT

STATUS_OPT is a parameter to select options regarding the status of signals. The AI function block offers four options: Propagate Fault Forward, Uncertain if Limited, BAD if Limited, and Uncertain if Man mode.

Propagate Fault Forward If the status from the sensor is Bad, Device failure or

Bad, Sensor failure, propagate it to OUT without generating an alarm. The use of these sub-statuses in OUT is determined by this option. Through this option, the user may determine whether alarming (sending of an alert) will be done by the block or propagated downstream for alarming

Uncertain if Man mode When the “Uncertain if Man” is enabled and the

Actual mode is Man, the OUT signal status should be “Uncertain”.

6.5.3 IO_OPTS

IO_OPTS is a parameter used to select whether options regarding input and output signals should be enabled or disabled. In the case of the AI function block, the only available option is “Low cutoff”. When enabling the low cut function for outputs, set this option.

The operation function of the AI function block can be selected from Direct, Indirect Linear, or Indirect SQRT: Direct : The Signal from the transducer block is directly output by filtering only, but without scaling or

square root extraction. Indirect Linear : Values scaled according to the range settings of XD_SCALE and OUT_SCALE are output. Indirect SQRT : Values are scaled according to the range settings of XD_SCALE and OUT_SCALE, and then

square root extraction is performed for them before being output. When the output value is smaller than the value set by this parameter, the output value is 0. To enable the low-cut

function, this parameter must be enabled in IO_OPTS.

7. IN-PROCESS OPERATION

This chapter describes the procedure performed when changing the operation of the function block of the EJX in process.

7.1 Mode T ransition

When the function block mode is changed to Out_Of_Service, the function block pauses and a block alarm is issued.

When the function block mode is changed to Manual, the function block suspends updating of output values. In this case alone, it is possible to write a value to the OUT parameter of the block for output. Note that no parameter status can be changed.

7.2 Generation of Alarm

7.2.1 Indication of Alarm

When the self-diagnostics function indicates that a device is faulty, an alarm (device alarm) is issued from the resource block. When an error (block error) is detected in each function block or an error in the process value (process alarm) is detected, an alarm is issued from each block. If an LCD indicator is installed, the error number is displayed as AL.XX. If two or more alarms are issued, multiple error numbers are displayed. For details of ALARM, refer to Section 8.2.

7. IN-PROCESS OPERATION

7.3 Simulation Function

The simulation function simulates the input of a function block and lets it operate as if the data was received from the transducer block. It is possible to conduct testing for the downstream function blocks or alarm processes.

A SIMULATE_ENABLE switch is mounted in the EJX amplifier. This is to prevent the accidental operation of this function. When this is switched on, simulation is enabled. (See Figure 7.2.) To initiate the same action from a remote terminal, if REMOTE LOOP TEST SWITCH is written to the SIM_ENABLE_MSG parameter (index 1044) of the resource block, the resulting action is the same as is taken when the above switch is on. Note that this parameter value is lost when the power is turned OFF. In simulation enabled status, an alarm is generated from the resource block, and other device alarms will be masked; for this reason the simulation must be disabled immediately after using this function.

The SIMULATE parameter of AI block consists of the elements listed in Table 7.2 below.

Parameters Description

Sets the data status to be simulated.

Sets the value of the data to be simulated.

Displays the data status from the transducer block. It cannot be changed.

Displays the data value from the transducer block. It cannot be changed.

Controls the simulation function of this block. 1: Simulation disabled (standard) 2: Simulation started

T0702.EPS

When Simulate En/Disable in Table 7.2 above is set to 2, the applicable function block uses the simulation value set in this parameter instead of the data from the transducer block. This setting can be used for propagation of the status to the trailing blocks, generation of a process alarm, and as an operation test for trailing blocks.

Appendix 1. Signal Characterizer (SC) Block

The Signal Characterizer (SC) block is used to convert the values of input signals according to a line-segment function. The line-segment function is created using 21 points of the X/Y coordinates specified by the user. This function block can also be used as a transmission line for control signals and supports backward control.

Application

The Signal Characterizer block is primarily used if you wish for one of the following reasons to correct signals using the coordinates rather than a computational expression:

• The computational expression for correction in relation to input signals is complex

•The relationship between input signals and the signals after correction is only empirically known

A1.2.2 Judging BLOCK_ERR

BLOCK_ERR indicates the cause of an error in the function block. If the cause of an error indicated by BLOCK_ERR occurs, the following configuration error is generated.

Name Description

1) "INFINITY" has been configured for CURVE_X and CURVE_Y.

2) "+INFINITY" has been configured for X1 of CURVE_X.

3) "+INFINITY" has been configured for Y1 of CURVE_Y.

Block Configuration Error

The mode changes to O/S if a block configuration error occurs.

4) A value of the array of CURVE_X does not increase in a monotone manner.

5) A configuration error when SWAP_2 is on

• A value of the array of CURVE_Y does not increase or decrease in a monotone manner.

6) The value of SWAP_2 is any value other than 1 or 2.

A1.3 Line-segment Factor Determination Section

When the mode is AUTO and no bit in BLOCK_ERR is set, the "gradient" and "intercept" of a line passing through two points that are considered line-segment approximation values are determined.

A1.3.1 Conditions for Configuring Valid Coefficients (CURVE_X, CURVE_Y)

No write error is generated with respect to the settings in CURVE_X and CURVE_Y. However, a configuration error occurs in the following cases:

1. "+INFINITY" has been configured for X1 or Y1.

2. "INFINITY" has been configured for each X or Y.

3. The values of CURVE_X are not increasing in a monotone manner (X1 < X2 < ... < X20 < X21). (If SWAP_2 is off, it is acceptable if the values of CURVE_Y do not increase or decrease in a monotone manner.)

4. The values of CURVE_Y are not increasing or decreasing in a monotone manner when SWAP_2 is on.

If a configuration error occurs, the Block Configuration Error bit in BLOCK_ERR is set, causing the mode to change to O/S.

Example of the case where SWAP_2 is off:

Figure A1.3 Example of Curve (SWAP_2 = off)

The range of CURVE_X: X1 to X6 (X7 and above are invalid because "+INFINITY" has been configured for X7*1.) The X1 to X6 values always increase in a monotone manner (X1 < X2 < X3 < X4 < X5 < X6). If an input value is smaller than X1, it is set to Y1. If an input value is larger than X6, it is set to Y6. The range of CURVE_Y: Y1 to Y6 It is acceptable if the Y1 to Y6 values do not increase in a monotone manner. However, if the setting of SWAP_2 is changed from off to on, the values of CURVE_Y must increase or decrease in

a monotone manner. Thus, if a value of CURVE_Y does not increase or decrease in a monotone manner in this setting, the mode changes to O/S, causing the Block Configuration Error bit in BLOCK_ERR to be set.

A1.5.1 Input Compensation

The following is an application example of pH compensation made by performing feedback control.

Appendix 1. Signal Characterizer (SC) Block

The pH is a value representing the degree of acidity or alkalinity and ranges from 0 to 14. pH 7 indicates neutral, a value smaller than 7 represents acidity, and a value larger than 7 denotes alkalinity. It is very difficult to control pH with a quickly changing reaction rate at a point near 7.

Appendix 2. Integrator (IT) Block

The Integrator (IT) block adds two main inputs and integrates them for output. The block compares the integrated or accumulated value to TOTAL_SP and PRE_TRIP and generates discrete output signals OUT_TRIP or OUT_PTRIP when the limits are reached.

The output is as represented by the following equation (for counting upward and rate conversion).

OUT.Value = Integration start value + Total Total = Total + Current Integral Current Integral = (x + y) ⫻ ∆t

x: IN_1 value whose unit has been converted y: IN_2 value whose unit has been converted ∆t: block execution period

Appendix 2. Integrator (IT) Block

A2.2 Input Process Section

When executed, the Integrator block first performs input processing in the order of: "Determining input status" → "Converting Rate or Accum" → "Determining the input flow direction" Switching between Convert Rate and Convert Accum is made using bit 0 (for IN_1) or bit 1 (for IN_2) of

INTEG_OPTS. INTEG_OPTS is one of the system parameters and should be set by the user. The values of IN_1 and IN_2 are not retained if the power is turned OFF.

A2.2.1 Determining Input Value Statuses

The following shows the correlation between the statuses of input parameters (IN_1, IN_2) and the statuses of input values used in the Integrator block.

Statuses of Input Parameters (IN_1, IN_2)

For addition (see A2.3), if the status of an input value is "Bad," the "Good" value just before the status changed to

TA0201.EPS

"Bad" is used. * Even if the Use Bad option is used, changing the internal status to "Good," the value of "Good" just before the

status changed to "Bad" is used.

A2.2.2 Converting the Rate

The following describes an example of rate conversion. In rate conversion, firstly convert the unit of two inputs to that based on seconds.

Next, convert the unit of the inputs to the same unit to be added together. The unit of IN_2 is standardized to that of IN_1. Then, calculates a weight, volume, or energy by multiplying each input value and block execution time. Because unit information is not input to the Integrator block as an input value, the user must input in advance tuned values to the TIME_UNIT1/2 and UNIT_CONV parameters.

A2.2.3 Converting Accumulation

This following describes an example of accumulation conversion. In accumulation conversion, the difference between the value executed previously and the value executed this time is

integrated or accumulated. This conversion applies when the output of a function block used as a counter is input to the input process of the Integrator block.

In order to convert the rate of change of an input to a value with an engineering unit, the user must configure the factor of conversion to the appropriate engineering unit in the PULSE_VAL1 and PULSE_VAL2 parameters.

Moreover, the unit of IN_2 is standardized to that of IN_1 in the same way as rate conversion. Thus, the user must also set an appropriate value to UNIT_CONV.

A2.2.4 Determining the Input Flow Direction

The Integrator block also considers the input flow direction. Information about the input flow direction is contained in REV_FLOW1 and REV_FLOW2 (0: FORWARD, 1: REVERSE).

In input processing, the sign of the value after rate and accumulation conversion is reversed if the REV_FLOW1 and REV_FLOW2 parameters are set to REVERSE. When determination of the flow direction of two input values is complete, these two inputs are passed to the adder. The settings in REV_FLOW will be retained even if the power is turned OFF.

IM 01C25T02-01E

Appendix 2. Integrator (IT) Block

A2.3 Adder

When input processing is complete, two arguments that have been rate and accumulate converted will be passed to the adder. The adder adds these two values according to the option.

A2.3.1 Status of Value after Addition

If one of the statuses of two arguments is "Bad" or if two of them are both "Bad," the status of the value after addition becomes "Bad." In this case, the value of "Good" just before the status changed to "Bad" is used as the addition value (see A2.1).

When the statuses of two arguments are both "Good," the status of the value after addition becomes "Good." In this case, the status of the value after addition will be used for the status applied to integration.

A2.3.2 Addition

The following three options are available for addition:

• TOTAL: Adds two argument values as is.

• FORWARD: Adds two argument values, regarding a negative value as "0."

• REVERSE: Adds two argument values, regarding a positive value as "0."

You can choose these options using bit 2 and bit 3 of INTEG_OPTS as follows:

Bit 3 of INTEG_OPTS (Flow Reverse)

Adder Options

TA0202.EPS

The result of the adder is passed to the integrator. If only one of the inputs is connected, the value of a non-connected input will be ignored.

A2.4 Integrator

When addition is complete, its result will be passed to the integrator. Integration consists of combinations of a reset method and counting up/down. There are the following seven integration

types, which can be set using INTEG_TYPE.

1. UP_AUTO : Counts up with automatic reset when TOTAL_SP is reached

2. UP_DEM : Counts up with demand reset

3. DN_AUTO : Counts down with automatic reset when zero is reached

4. DN_DEM : Counts down with demand reset

5. PERIODIC : Counts up and is reset periodically according to CLOCK_PER

6. DEMAND : Counts up and is reset on demand

7. PER&DEM : Counts up and is reset periodically or on demand Each type of integration is independently run as a function. There are the following four types of integrated values:

1. Total: Integrates the result of the adder as is.

2. ATotal: Integrates the absolute value of the result of the adder.

3. RTotal: Integrates the absolute value of the result of the adder only if the status of the result is "Bad."

This value is used for the RTOTAL value.

4. AccTotal: An extension function. The result of the adder is integrated as is and will not be reset. The value is used for the ACCUM_TOTAL (expanded parameter) value. The table A2.1 shows the details of INTEG_TYPE.

A2.5 Output Process

There are the following three output parameters:

1. OUT

2. OUT_TRIP

3. OUT_PTRIP Parameters OUT_TRIP and OUT_PTRIP are used only when INTEG_TYPE is a value from 1 to 4.

A2.5.1 Status Determination

The same criteria for determining the status of the output of the Integrator block are used in common for the above three parameters.

Bad

0% UNCERT_LIM GOOD_LIM 100%

PCT_INCL=100(1 - (msp of RTotal)/(msp of ATotal))

msp of RTotal: RTotal value that is converted into a short floating-point number msp of ATotal: ATotal value that is converted into a short floating-point number RTotal: Integrated value of the absolute values of the increments whose status is bad ATotal: Integrated value of the absolute values of the increments regardless of the output status

Figure A2.4 Status of OUT, OUT_TRIP, and OUT_PTRIP Outputs

OUT.Value, OUT_TRIP.Status, and OUT_PTRIP.Status are determined by the ratio of the "Good" integrated values to all integrated values, which is stored in PCT_INCL (0% to 100%). The user must set the threshold value of each status to UNCERT_LIM and GOOD_LIM.

The Integrator block determines the status of the output using the three parameters: PCT_INCL, UNCERT_LIM, and GOOD_LIM.  PCT_INCLGOOD_LIM

⇒Good  UNCERT_LIMPCT_INCL"GOOD_LIM

⇒Uncertain

Appendix 2. Integrator (IT) Block

A2.5.2 Determining the Output Value

The value of OUT.Value is determined as follows:

 For counting up OUT = integration start value (0) + Total  For counting down OUT = integration start value (TOTAL_SP) _ Total Total: Total of integrated values. This value is retained even if INTEG_TYPE is changed during integration

(in AUTO).

If OUT is rewritten in the MAN mode, integration starts with the value rewritten in MAN mode after the mode was returned to AUTO.

The values in OUT_TRIP and OUT_PTRIP are determined according to the correlation between OUT and TOTAL_SP/PRE_TRIP.

IM 01C25T02-01E

For counting up, the OUT value is as follows:

 OUT < TOTAL_SP - PRE_TRIP

⇒OUT_TRIP = 0, COUT_PTRIP = 0

 TOTAL_SP - PRE_TRIP <= OUT < TOTAL_SP

⇒OUT_TRIP = 0, COUT_PTRIP = 1

 TOTAL_SP <= OUT

⇒OUT_TRIP = 1, COUT_PTRIP = 1

For counting down, the OUT value is as follows:

 PRE_TRIP < OUT

⇒OUT_TRIP = 0, COUT_PTRIP = 0

 0 < OUT <= PRE_TRIP

⇒OUT_TRIP = 0, COUT_PTRIP = 1

OUT <= 0

⇒OUT_TRIP = 1, COUT_PTRIP = 1

Note that the given conditions do not apply to the following cases:

Appendix 2. Integrator (IT) Block

• If INTEG_TYPE is 5, 6, or 7, OUT_TRIP and OUT_PTRIP always output "0."

• If INTEG_TYPE is 1 or 3, occurrence of AutoRESET (reset caused if the threshold is exceeded) causes

OUT_TRIP to hold "1" for five seconds.

A2.5.3 Mode Handling

Mode Action Output

Automatic (AUTO)

Manual (MAN)

Out of Service (O/S)

If you rewrite the value in OUT and RTOTAL while the mode is in MAN or O/S, N_RESET is incremented.

Normal action Normal output Integration calculation is stopped.

OUT will not be updated unless you set a value to it. No reset is accepted.

You may rewrite a value in OUT. If no value is rewritten, the value just before running in AUTO is held. When the mode returns to AUTO, integration starts with the written value or the value just before running in AUTO.

A2.6 Reset

A2.6.1 Reset Trigger

There are the following five types of reset triggers:

1. An integrated value exceeds TOTAL_SP.

2. An integrated value falls below "0."

3. RESET_IN is "H."

4. Every period specified in CLOCK_PER (for more information, see CLOCK_PER in A2.6.2)

5. OP_CMD_INT is 1. The table A2.2 shows the correlation between INTEG_TYPE and RESET triggers.

TA0205.EPS

When OP_CMD_INT has become "H" and a reset was made, OP_CMD_INT automatically returns to "L." Even if RESET_IN becomes "H," activating a reset, RESET_IN does not automatically return to "L." The RESET_IN setting will not be retained if the power is turned OFF.

A2.6.2 Reset Timing

All items are reset during execution of the function block. Therefore, the minimum period of a reset is the block execution period.  5-second rule If a reset is made, the next reset will not be accepted for 5 seconds after that. Even if UP_AUTO (or DN_AUTO) is activated and TOTAL_SP (or 0) is reached within 5 seconds, the next reset

will not be made for 5 seconds from the previous reset.  CLOCK_PER If INTEG_TYPE is PERIODIC (5) or PER&DEM (7), a reset is made at the period (sec) set to the CLOCK_PER

parameter. If the value in CLOCK_PER is smaller than the function block's execution period, bit 1 of BLOCK_ERR "Block

Configuration Error" is set.

A-17

IM 01C25T02-01E

Appendix 2. Integrator (IT) Block

A2.6.3 Reset Process

The basic reset process sequence is as follows:

1.) Snapshot

2.) Clearing the integrated values

3.) Reset count increment

4.) Judging OUT_TRIP and OUT_PTRIP (see A2.5)

1.) Snapshot

Saves the following values in the specified parameters before clearing the integrated values. These values will be retained until the next reset is made.

STOTAL = Total SRTOTAL = RTotal SSP = TOTAL_SP

2.) Clearing the integrated values

The reset process clears the Total, ATotal, and RTotal values in the internal registers.

Total = 0 ATotal = 0 RTotal = 0

3.) Reset count increment

Each time a reset is made, the N_RESET parameter will be incremented. The high limit is 999,999, and if this limit is exceeded, the count returns to "0."

4.) Judging OUT_TRIP and OUT_PTRIP (see A2.5)

OUT_TRIP and OUT_PTRIP are judged again on the basis of the cleared integrated values. There are three options relating to a reset:

i Confirm reset (bit 8 of INTEG_OPTS) ii Carry (bit 6 of INTEG_OPTS) iii Generate reset event (bit 9 of INTEG_OPTS)

i Confirm reset (bit 8 of INTEG_OPTS)

If this option is enabled, the next reset is rejected until "1" is set to RESET_CONFIRM.

ii Carry (bit 6 of INTEG_OPTS)

If this option is enabled while INTEG_TYPE is UP_AUTO or DN_AUTO, the value exceeding the threshold at a reset will be carried into the next integration. If INTEG_TYPE is any setting other than UP_AUTO or DN_AUTO, this option is irrelevant.

iii Generate reset event (bit 9 of INTEG_OPTS)

If this option is enabled, an alert event is generated if a reset occurs.

Appendix 3. Input Selector (IS) Block

The function of the Input Selector (IS) block is to automatically select one signal from multiple input signals using a specified selection method.

The IS block is used for selective control in which one measured quantity is selected from multiple measured quantities to be transmitted to the controller as a controlled variable. This feature is primarily used for temperature control systems.

Output Parameters (Computation or Selection Results)

OUT: Block output SELECTED: Indicates the input number selected using the alternatives.

Other Parameters

OUT_RANGE : Sets the OUT range. STATUS_OPTS : Option used to specify the handling of various statuses. SELECT_TYPE : Determines the input selection algorithm. MIN_GOOD : Parameter specifying the minimum required number of inputs with “good” status. If the number

of inputs that are “good” is less than the value of MIN_GOOD, input selection is canceled.

Mode

O/S : Allows configuration change, but disables input value output. Man : Allows internal processing, but the output value may vary depending on the definition of usage conditions. Auto : Outputs the input value.

The Input Selector (IS) block offers a maximum of eight input alternatives and generates the output according to the configured action. This block generally receives inputs from the Analog Input (AI) function block. The function of the IS block is to select a maximum, minimum, middle, average, “first good,” or “latched good” signal. The block combines parameter configuration (DISABLE_n) and option (“first good”) to give priority to alternative(s) or to function as a rotary position switch. When used as a rotary position switch, the block can receive operator inputs or switch information from connected inputs.

The IS block supports the concept of middle selection. This function outputs the average of two middle signals if even multiple valid signals are configured or a middle signal if odd multiple valid signals are configured. Application of the block is to supply a selected control signal in the forward path.

The SELECTED parameter is the 2nd output indicating which input has been selected using the algorithm.

A3.3.1 OP_SELECT Handling

When a value other than “0” (that is, 1 to 8) is selected for OP_SELECT: The IS block selects the input of the number specified by OP_SELECT regardless of the setting of SELECT_TYPE,

propagates the value of that input to OUT, and transmits the input number to SELECTED.

Figure A3.3 Example (2)

In the above example, SELECT_TYPE is set to Minimum. However, because OP_SELECT specifies the value and number of IN_3, the value and number of this specified IN are transmitted to OUT and SELECTED.

* Note: Even if the IN specified by OP_SELECT is an invalid input (the corresponding DISABLE parameter is ON or the IN’s status is “bad”),

the value and status of that IN are transmitted to OUT.

Appendix 3. Input Selector (IS) Block

When SELECT TYPE is “Middle”

If there is more than one valid input and the number of such input is an odd number, the value of the middle input will be transmitted to OUT. If there is an even number of valid inputs, the average of the middle two inputs is transmitted to OUT. If the average is used for OUT, the block transmits “0” to SELECTED, while it transmits the number of the input used for the middle for other cases. If the number of valid inputs is 1, it is irrelevant to selection by “Middle” selector action. The following shows an example of selection by “Middle” selector action.

If there is an even number of valid inputs:

Because DISABLE_1, DISABLE_2, DISABLE_7, and DISABLE_8 are ON, the corresponding IN_1, IN_2, IN_7, and IN_8 are disabled and the remaining four INs are enabled. Furthermore, because IN_3 has the maximum value and IN_4 has the minimum value among the valid INs, they are not selected and the average of IN_5 and IN_6 inputs is output.

When SELECT TYPE is “Latched Good”

The valid input with the smaller input number is selected as an output and is held until it becomes invalid. When it becomes invalid, the next valid input will be selected as an output regardless of the magnitude of the value. Even if an input with the input number smaller than that of the currently selected input recovers, the current selection is held.

Assuming that IN_2 is the valid input with the smallest input number, the order of input selection is IN_2 → IN_3 →

...→ IN_8 → IN_1 → ....

If the power is turned OFF and then ON with SELECT TYPE set to “Latched Good,” input selection starts with the IN that was selected before the power was turned OFF.

A3.4 Output Processing

A3.4.1 Handling of SELECTED

For the value output to SELECTED when OP_SELECT has been selected (that is, not “0”), the number specified by OP_SELECT will be stored as is.

However, “0” is stored in the SELECTED in the following cases:

1. If there is no valid input;

2. If the value of MIN_GOOD is greater than the number of valid inputs;

3. If the input status is “bad” or “uncertain” when the value of OP_SELECT is anything other than “0” (with the exception of the case where the “Uncertain as good” bit in STATUS_OPTS is set.);

4. If the value of OP_SELECT is greater than 8, which is the maximum number of inputs;

5. If the value is out of the SELECT_TYPE setting range when the value of OP_SELECT is zero.

As long as there is one valid input, even an invalid input can be selected for OP_SELECT.

If the number of valid inputs is greater than the value of MIN_GOOD, the number of the input (including an invalid input) specified by OP_SELECT will be stored in SELECTED. Therefore, even if an invalid input is selected, SELECTED does not become zero.

If no input is selected for OP_SELECT, the output of SELECTED will depend on SELECT_TYPE. The Table A3.1 shows the value of SELECTED according to the number of valid inputs and SELECT_TYPE.

The following describes the temperature control system of a fixed bed-type reactor. In this case, there are instances where the point showing the maximum temperature changes due to catalytic deterioration, raw material flow, etc. Therefore, a large number of measurement points are provided, and the maximum value obtained among these measurement points is input to the controller to control reactor temperature.

Appendix 4. Arithmetic (AR) Block

The Arithmetic (AR) block switches two main inputs of different measurement ranges seamlessly and combines the result with three auxiliary inputs through the selected compensation function (10 types) to calculate the output.

A4.1 Arithmetic Function Block Schematic

The diagram below shows the Arithmetic block schematic.

Figure A4.1 AR Block

The Arithmetic block is divided into three sections:

· Input section: Makes a go/no-go decision on the use of an input value, switches the range, and determines the PV status.

· Computation section: Makes calculations through ARITH_TYPE.

· Output section: Applies gain multiplication and bias addition to the calculated result to perform limitation processing for output.

* The range extension function compensates the IN and IN_LO input values when two devices with different ranges

are connected, to make smooth input switching.

FA0401.EPS

IM 01C25T02-01E

Appendix 4. Arithmetic (AR) Block

A4.2 Input Section

There are five inputs: IN and IN_LO main inputs and IN_1, IN_2, and IN_3 auxiliary inputs.

IN and IN_LO are intended to connect devices with different measurement ranges and allow the use of switching a measurement range by selecting the measuring device. However, because there are slight differences between IN and IN_LO values even when the same item is measured, instantaneous switching causes abrupt changes in the output.

To prevent this phenomenon, the Arithmetic block uses a function known as range extension to compensate the IN and IN_LO values between RANGE_HI and RANGE_LO. This enables the input to be switched smoothly. The result of the range extension function is substituted into PV to be used for calculations.

A4.2.1 Main Inputs

The range extension function determines the PV value in the following order:

1. If IN  RANGE_HI → PV = IN

2. If IN  RANGE_LO → PV = IN_LO

3. If RANGE_HI > IN > RANGE_LO → PV = g

 IN + (1- g)  IN_LO

g = (IN - RANGE_LO) / (RANGE_HI -

RANGE_LO)

RANGE_HI and RANGE_LO are threshold values

for switching two main inputs seamlessly.

PV is a parameter with status information, and PV status is determined by the value of “g.”

If “g” < 0.5 → The status of IN_LO is used. If “g”  0.5 → The status of IN is used.

Determination of the status is made with a hysteresis of 10% provided for 0.5.

If RANGE_LO > RANGE_HI, the statuses of PV and OUT are “Bad. Configuration Error.” Then “Configuration Error” is output to BLOCK_ERR.

If there is only one main input, the input is incorporated into the computation section as is, not taking into account RANGE_HI and RANGE_LO.

Example:

Assuming that

RANGE_LO 20 RANGE_HI 300

TA0401.EPS

the following are established:

IN = 310, IN_LO = 20 IN = 230, IN_LO = 20 → g = (230 - 20) / (300 - 20) = 0.75

IN = 90, IN_LO = 20 → g = (90 - 20) / (300 - 20) = 0.25

IN = 19, IN_LO = 10 → PV = 10

→ PV = 310

PV = 0.75  230 + (1 - 0.75)

 20 = 177.5

PV = 0.25  230 + (1 + 0.25)

 20 = 37.5

There are bias and gain parameters for the IN_1, IN_2, and IN_3 auxiliary inputs. The following shows the equation using them.

t_i = (IN_i + BIAS_IN_i)  GAIN_IN_i

The bias parameter is used for calculating absolute temperature or absolute pressure, while the gain parameter is used for normalization of square root extraction.

Reserved

There are options called “IN Use uncertain” and “IN_LO Use uncertain” for the IN and IN_LO inputs. When these options are valid, IN and IN_LO are internally interpreted as “good” IN and IN_LO even if their statuses are “uncertain.” (There is no option for “bad” status.)

For the IN_1, IN_2, and IN_3 auxiliary inputs, there are options known as “IN_i Use uncertain” and “IN_i Use bad.” If these options are valid, an IN_i with “uncertain” or “bad” status is internally interpreted as a “good” IN_i.

* The exception is that if the input status is “Bad. Not

Connected,” INPUT_OPTS does not apply and the input is considered “bad” as is.

A4.2.4 Relationship between the Main

Inputs and PV

The value and PV status are determined by the statuses of two main inputs, INPUT_OPTS, and RANGE_LO and RANGE_HI.

· If the statuses of two main inputs are both “good” or anything other than “good” See A4.2.1, Main Inputs.

· If only one of two main inputs has “good” status after application of INPUT_OPTS, the PV value is determined as follows:

· If the status of IN is “good” and that of “IN_LO” is anything other than “good”

IN > RANGE_LO → PV = IN IN  RANGE_LO → See A4.2.1.
