3.1 Outline

Fieldbus is a bi-directional digital communication protocol for ﬁ eld devices, which offers an advancement in implementation technologies for process control systems and is widely employed by numerous ﬁ eld devices. The Fieldbus communication type of the digitalYEWFLO employs the speciﬁ cation standardized by the Fieldbus FOUNDATION, and provides interoperability between Yokogawa devices and those produced by other manufacturers. Featuring two AI and two DI function blocks in each, the Fieldbus communication type’s software enables a ﬂ exible instrumentation system to be implemented. 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

digitalYEWFLO

Each digitalYEWFLO contains two Virtual Field Devices (VFDs) 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).

3.2.2 Function Block VFD

(1) Resource (RS) block

• Manages the status of digitalYEWFLO hardware.

• Automatically informs the host of any detected faults or other problems.

(2) Transducer (TR) block

• Converts the ﬂ ow sensor output to the volumetric ﬂ ow rate signal and transfers to an AI function block (AI1).

• With the option /MV

- Converts temperature sensor output to the

process ﬂ uid temperature and calculates the ﬂ uid density.

- Calculates the mass ﬂ ow rate from the ﬂ uid

density thus obtained and the volumetric ﬂ ow rate obtained with the ﬂ ow sensor.

- Transfers these calculation results to AI

function blocks.

• Transfers limit switch signals to DI function blocks.

(3) AI function blocks (three)

• Output ﬂ owrate and temperature.

• Condition raw data from the TR block.

• Carry out scaling and damping (with a ﬁ rst- order lag), and allow input simulation.

(4) DI function blocks (two)

• Limit switches for the ﬂ ow rate and temperature (option /MV).

(5) IT function block (one)

• Accumulate given values.

(6) AR function block (one)

• Calculate input values.

(7) PID function block (option /LC1)

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

Various parameters, the node address, and the PD tag shown in Figure 3.1 must be set before using the device. Refer to Chapter 4 and onward for the setting procedures.

3.4 Wiring System Conﬁ guration

The number of devices that can be connected to a single bus and the cable length vary depending on system design. When constructing systems, both the basic and overall design must be carefully considered to achieve optimal performance.

IM 01F06F00-01EN

<4. GETTING STARTED>

4. GETTING STARTED

4-1

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 ﬁ eldbus devices in accordance with the procedures described in this section. The procedures assume that ﬁ eldbus devices will be set up on a bench or in an instrument shop.

4.1 Connection of Devices

The following instruments 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.

• 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 the digitalYEWFLO, use terminal lugs applicable to M4 screw terminals. 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.

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 the improvement of reliability. If the power is turned off within 60 seconds after setting is made, the modiﬁ ed parameters are not saved and the settings may return to the original values.

<4. GETTING STARTED>

Unless otherwise speciﬁ ed, the following settings are in effect when shipped from the factory. If no digitalYEWFLO is detected, check the available address range. If the node address and PD Tag are not speciﬁ ed when ordering, default value is factory set. If two or more digitalYEWFLOs are connected at a time with default value, only one digitalYEWFLO will be detected from host as digitalYEWFLOs have the same initial address. Connect the digitalYEWFLOs one by one and set a unique address for each.

NOTE

When using a capabilities ﬁ le (CFF), make sure you use the right ﬁ le for the intended device. The digitalYEWFLO is offered in two types in terms of capabilities:

• General type: AI function blocks (three), DI function blocks (two), AR function block (one), and IT function block (one).

• With the option /LC1: A PID function block

4.4 Integration of DD

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

594543 : the manufacturer number of

Yokogawa Electric Corporation

0009 : the device number of digitalYEWFLO

If this directory is not found, the DD for the digitalYEWFLO has not yet been installed. Create this directory and copy the DD ﬁ les (0m0n.ffo and 0m0n.sym to be supplied separately where m and n are numerals) to it. If you do not have the DD ﬁ les for the digitalYEWFLO, you can download them from our web site. Visit the following web site.

http://www.yokogawa.com/ﬂ d/

Once the DD is installed in the directory, the name and attribute of all parameters of the digitalYEWFLO are displayed.

Off-line conﬁ guration is possible using the capabilities ﬁ le.

Using the wrong CFF ﬁ le may result in an error when downloading the conﬁ gured data to the device. Also, use the right DD ﬁ les that accommodate the revision of the intended device.

4.5 Reading the Parameters

To read digitalYEWFLO parameters, select the AI block of the digitalYEWFLO from the host screen and read the OUT parameter. The current ﬂ ow rate is displayed. Check that MODE_BLK of the function block and resource block is set to AUTO.

4.6 Continuous Record of Values

If the host has a function of continuously records the indications, use this function to list the indications (values). Depending on the host being used, it may be necessary to set the schedule of Publish (the function that transmits the indication on a periodic basis).

IM 01F06F00-01EN

<4. GETTING STARTED>

4.7 Generation of Alarm

If the host is allowed to receive alarms, generation of an alarm can be attempted from the digitalYEWFLO. In this case, set the reception of alarms on the host side. The digitalYEWFLO’s VCR-7 is factory-set for this purpose. For practical purposes, all alarms are placed in a disabled status; for this reason, it is recommended that you ﬁ rst use one of these alarms on a trial basis. Set the value of link object-3 (index 30002) as “0, 299, 0, 6, 0”. Refer to Subsection 5.6.1 “Link Objects” for details. Since the LO_PRI parameter (index 4029) of the AI block is set to “0”, try setting this value to “3”. Select the Write function from the host in operation, specify an index or variable name, and write “3” to it. The LO_LIM parameter (index 4030) of the AI block determines the limit at which the lower bound alarm for the process value is given. In usual cases, a very small value is set to this limit. Set smaller value than 100% value of XD_SCALE (same unit). Since the ﬂ ow rate is almost 0, a lower bound alarm is raised. Check that the alarm can be received at the host. When the alarm is conﬁ rmed, transmission of the alarm is suspended.

This chapter describes how to adapt the function and performance of the digitalYEWFLO to suit speciﬁ c applications. Because multiple devices are connected to Fieldbus, it is important to carefully consider the device requirements and settings when conﬁ guring the system. The following steps must be taken.

(1) Network design

Determines the devices to be connected to

Fieldbus and checks the capacity of the power supply.

(2) Network deﬁ nition

Determines the PD tag and node addresses for

all devices.

(3) Deﬁ nition of combining function blocks

Determines how function blocks are combined.

(4) Setting tags and addresses

Sets the PD Tag and node addresses for each

device.

(5) Communication setting

Sets the link between communication

parameters and function blocks.

(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 conﬁ guration tool signiﬁ cantly simpliﬁ es this procedure. Refer to APPENDIX 7 “LINK MASTER FUNCTIONS” when the digitalYEWFLO is used as Link Master.

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

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 power supply.

• Terminator

Fieldbus requires two terminators. Refer to

the supplier for details of terminators that are attached to the host.

• Field devices

Connect the ﬁ eld devices necessary for

instrumentation. The digitalYEWFLO 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 ﬁ eld devices. A minimum of

one device with bus control function is needed.

• Cable

Used for connecting devices. Refer to “Fieldbus

Technical Information” (TI 38K03A01-01E) for details of instrumentation cabling. Provide a cable sufﬁ ciently long to connect all devices. For ﬁ eld 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. For the digitalYEWFLO, the maximum current (power supply voltage: 9 to 32 VDC) is 15 mA. The cable used for the spur must be of the minimum possible length.

5.2 Network Deﬁ nition

Before connection of devices with Fieldbus, deﬁ ne the Fieldbus network. Allocate PD tags and node addresses to all devices (excluding such passive devices as terminators). The PD tags are the same as conventional tag numbers assigned to devices. Up to 32 alphanumeric characters may be used for deﬁ nition of the PD tag for each device. Use hyphens as delimiters as required.

IM 01F06F00-01EN

<5. CONFIGURATION>

5-2

The node addresses are used to locate devices for communication purposes. Since a PD tag is too long a data value, the host substitutes the node addressed for PD tags in communication. Node addresses can be set to numbers in a range of decimal 20 to 247 (hexadecimal 14 to F7). Assign devices having link master functionality (i.e., LM devices) from the smallest address number (0x14) in order, and other devices (i.e., basic devices) from the largest (0xF7). Assign an address in the range for basic devices to a digitalYEWFLO. Only when using a digitalYEWFLO with LM function as an LM device, assign an address in the range for LM devices to it. These address ranges are determined by the following parameters.

to the address range used for the host or other LM device.

Unused address range

Any devices within an address range written as “Unused” in Figure 5.1 cannot join the ﬁ eldbus. Other address ranges are periodically scanned to ﬁ nd any devices newly joining the ﬁ eldbus. Do not widen the available address ranges unnecessarily; the ﬁ eldbus communication performance may be severely degraded.

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 speciﬁ cation of each device for details.

5.3 Function Block Link Deﬁ nitions

Link the input/output parameters of function blocks to each other as necessary. For a digitalYEWFLO, the output parameters of three AI blocks (OUTs), those of two DI blocks (OUT_Ds), input/output parameters of AR block, IT block and optional PID block (option /LC1) should be linked to parameters of different function blocks. Speciﬁ cally, link settings must be written to the link object in the digitalYEWFLO. For details, refer to Section 5.6 “Block Setting.” It is also possible to read values from the host at appropriate intervals instead of linking the outputs of digitalYEWFLO’s function blocks to other blocks. The linked blocks need to be executed synchronously with other blocks and the communication schedule. In this case, change the schedule of the digitalYEWFLO according to Table 5.3, in which factory settings are shown in parentheses.

Setting of Tags and Addresses

This section describes the steps in the procedure to set the PD tags and node address in the digitalYEWFLO. 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. Whenever you have changed the PD tag or address of a digitalYEWFLO, transfer its state to SM_ OPERATIONAL.

In each digitalYEWFLO, the PD tag and node address are set to “FT1003” and 242 (hexadecimal F2), respectively, before shipment from the factory unless otherwise speciﬁ ed. To change only the node address, clear the address once and then set a new node address. To set the PD tag, ﬁ rst clear the node address and clear the PD tag, then set the PD tag and node address again. Devices whose node address have been cleared will await at 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 YF100 is 5945430009xxxxxxxx. (The xxxxxxxx at the end of the above device ID is a total of 8 alphanumeric characters. Available characters are as follws.)

5.5 Communication Setting

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

5.5.1 VCR Setting

Set VCR (Virtual Communication Relationship), which speciﬁ es the called party for communication and resources. Each digitalYEWFLO has 33 VCRs whose application can be changed, except for the ﬁ rst VCR, which is used for management. Each digitalYEWFLO 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 User-

triggered 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 outputs of the AI blocks, DI

blocks, AR block, IT block and PID block to other

function blocks. 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 AR block, IT block and PID block.

Each VCR has the parameters listed in Table 5.4. Parameters must be changed together for each VCR because modiﬁ cation for each parameter may cause a contradiction.

5.6.2 Trend Objects

It is possible to make settings so that a function block automatically transmits the trend. For this, each digitalYEWFLO has ten trend objects: eight for trends of analog parameters and two for discrete parameters. For each trend object, specify a single parameter, the trend of which is to be transmitted. Each trend object has the parameters listed in Table 5.8. For the ﬁ rst four parameters, setting is mandatory. Before writing parameter settings to a trend object, parameter WRITE_LOCK of the resource block must be modiﬁ ed to unlock the write-lock.

6. EXPLANATION OF BASIC ITEMS

This chapter describes basic TR (Transducer block), AI, and DI function block parameter setting, displays of the integral indicator. For detailes of the function blocks, refer to APPENDIX.

This chapter contains information on how to adapt the function and performance of the digitalYEWFLO to suit speciﬁ c applications. Because two or more devices are connected to FOUNDATION Fieldbus, settings including the requirements of all devices need to be determined. Practically, the following steps must be taken.

The following section describes each step of the procedure in the order given. Using a dedicated conﬁ guration tool allows the procedure to be signiﬁ cantly simpliﬁ ed. This section describes the procedure which has relatively simple functions.

6.1 Setting and Changing Parameters for the Whole Process

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 modiﬁ ed parameters are not saved and the setting may return to the original values.

Block mode

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 four sub-parameters below. (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 AI Function Block Parameters

Parameters of the three AI function blocks can be read and written from the host. AI1: Flow rate, AI2: Temperature, AI3: Volumetric ﬂ ow rate for the use of mass ﬂ ow rate calculation at AR function block. For each block parameter in digitalYEWFLO, refer to APPENDIX 1 “LIST OF PARAMETERS FOR EACH BLOCK OF digitalYEWFLO.” The following describes important parameters and how to set them.

MODE_BLK:

Indicates the three types of function block

modes; Out_Of_Service, Manual, and Auto. In Out_Of_Service mode, the AI block does not operate. The Manual mode does not allow values to be updated. The Auto mode causes the measured value to be updated. Under normal circumstances, set the Auto mode to take effect. The Auto mode is the factory default.

CHANNEL:

This is the parameter of the transducer block to

be input to the AI block. AI1 block is assigned ﬂ ow rate. AI2 block is assigned temperature. AI3 block is assigned volumetric ﬂ ow rate for AR block.

This setting can not be changed.

XD_SCALE:

Scale of input from the transducer block. The

maximum ﬂ ow rate range in the registered sizing data is setting. “0” (0%), “10.000” (100%), and “m3/h” for the unit are factory-set in case of UNCALIBRATION order. Changing the unit (can be set only in ﬂ ow rate) also causes the unit within the transducer block to be automatically changed. (The unit is automatically changed according to the unit selected by AI1, AI2.) Units which can be set by XD_SCALE are shown in Table 6.2.

The setting range of the 100% scale (XD_

SCALE.EU at 100) depends on the unit setting (XD_SCALE.Units Index) as shown in Table 6.3.

OUT_SCALE:

Sets the range of output (from 0% to 100%).

Available units for OUT_SCALE are the same as units for XD_SCALE in Table 6.2 and percentage.

L_TYPE:

Speciﬁ es the operation function of the AI1 block.

The factory default is “Direct”, so the input delivered to CHANNEL is directly reﬂ ected on OUT. If set to “Indirect”, scaling by XD_SCALE

and OUT_SCALE is carried out and is reﬂ ected on OUT. “Indirect SQRT” is not used for a digitalYEWFLO.

PV_FTIME:

Sets the time constant of the damping function

within AI block (primary delay) in seconds.

Alarm Priority:

Indicates the priority of the process alarm.

If a value of 3 or greater is set, an alarm is transmitted. The factory default is 0. Four types of alarm can be set: HI_PRI, HI_HI_PRI, LO_ PRI, and LO_LO_PRI.

Alarm Threshold:

Sets the threshold at which a process alarm is

generated. The factory default setting is a value that does not generate an alarm. Four types of alarm can be set: HI_LIM, HI_HI_LIM, LO_LIM, and LO_LO_LIM.

6.4 Parameters of DI Function Block

DI function blocks work based on the limit switch signals generated by the transducer block where DI1 is based on those signals on the ﬂ ow rate and DI2 on the temperature (with the option /MV).

MODE_BLK

Supports O/S, Auto, and Manual modes. The DI block does not function in the O/S mode, does not update the measured value in the Manual mode, and updates the measured value in the Auto mode. Normally, set the mode to Auto. Before the digitalYEWFLO is shipped from the factory, all the DI blocks are set to O/S mode.

CHANNEL

Selects the input to the DI block from the transducer. CHANNEL is always set to 3 or 4 for a digitalYEWFLO.

PV_FTIME

7. IN-PROCESS OPERATION

7-1

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

7.1 Mode Transition

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 ALXX. If two or more alarms are issued, multiple error numbers are displayed in 2-second intervals. (when “1” is set to DISPLAY_CYCLE).

The error details corresponding to alarm indications on the LCD indicator and whether or not switches are provided to disable the corresponding alarms are shown in Table 7.1. For the alarms for which an alarm mask switch is provided, the default alarm settings are also shown. Those alarms for which an alarm mask switch is not provided are enabled at all times. For how to modify these mask switch statuses, refer to APPENDIX 3 “OPERATION OF EACH PARAMETER IN FAILURE MODE.”

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 jumper switch is mounted on the digitalYEWFLO’s ampliﬁ er. This is to prevent the accidental operation of this function. When this is switched on, simulation is enabled. (Refer to Figure 7.2.) To initiate the same action from a remote terminal, if REMOTE LOOP TEST SWITCH is written to SIM_ENABLE_MSG (index 1044) parameter 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 7.3 below.

When Simulate En/Disable in Table 7.3 above is set to “Active”, 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.

• FISCO rules

The FISCO Concept allows the interconnection of intrinsically safe apparatus to Safety Barrier not speciﬁ cally examined in such combination. The criterion for such interconnection is that the voltage (Vmax), the current (Imax) and the power (Pi) which intrinsically safe apparatus can receive and remain intrinsically safe, considering faults, must be equal or greater than the voltage (Uo, Voc, Vt), the current (1o, Isc, It,) and the power (Po) which can be provided by the Safety Barrier (supply unit). In addition, the maximum unprotected residual capacitance (Ci) and inductance (Li) of each apparatus (other than the terminators) connected to the Fieldbus must be less than or equal to 5nF and 10 H respectively. In each I.S. Fieldbus segment only one active source, normally the Safety Barrier, is allowed to provide the necessary power for the Fieldbus system. The allowed voltage (Uo, Voc, Vt) of the Safety Barrier used to supply the bus must be limited to the range of 14V d.c. to 24V d.c. 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 to a leakage current of 50 A for each connected device. Separately powered equipment needs a galvanic isolation to insure that the intrinsically safe Fieldbus circuit remains passive. The cable used to interconnect the devices needs to comply with the following parameters: Loop resistance R’: 15 ... 150 /KM Inductance per unit length L’: 0.4 ... 1mH/km Capacitance per unit length C’: 80 ... 200 nF/km C’ = C’ line/line + 0.5 C’ line/screen, if both lines are ﬂ oating or C’= C’ line/line + C’ line/screen, if the screen is connected to one line Length of spur Cable: max. 30m Length of trunk cable: max. 1Km Length of splice: max. 1m Terminators At each end of the trunk cable an approved line terminator with the following parameters is suitable: R = 90 ... 100 C = 0 ... 2.2 F. System evaluation The number of passive devices like transmitters, actuators, connected to a single bus segment is not limited due to I.S. reasons. Furthermore, if the above rules are respected, the inductance and capacitance of the cable need not to be considered and will not impair the intrinsic safety of the installation.

Installation Notes For FISCO and Entity Concepts:

1. The Intrinsic Safety Entity concept allows the interconnection of FM Approved Intrinsically safe devices with entity parameters not speciﬁ cally examined in combination as a system when:

Uo or Voc or Vt  Vmax, Io or Isc or It  Imax, Po  Pi. Ca or Co  Ci + Ccable, For inductance use

either La or Lo  Li + Lcable or Lc/Rc  (La/Ra or Lo/Ro) and Li/Ri  (La/Ra or Lo/Ro)

each of these tags. Refer to Section 5.4 “Setting of Tags and Addresses.”

Sets the range of input from the transducer block corresponding to the 0% and 100% points in operation within the AI1 function block. The maximum ﬂ ow rate range in the registered sizing data is the factory default setting. Set four data: the unit of the range, the input value at the 0% point (always 0 for a digitalYEWFLO), the input value at the 100% point (equal to the ﬂ ow span), and the decimal point position.

Set the scale of output corresponding to the 0% and 100% points in operation within the AI function block. It is possible to set a unit and scale that differ from the measurement range. Set four data: the unit of the scale, the output value at the 0% point (i.e., the lower output scale limit), the output value at the 100% point (i.e., the upper output scale limit), and the decimal point position.

Select the calculation function of each AI function block from the following:

• Direct: The output of the transducer block is directly output only via ﬁ ltering without scaling and square root extraction (in the range set in XD_SCALE).

• Indirect: Proportional scaling is applied to the input to the AI function block, and the result is output (in the range set in OUT_SCALE).

• IndirectSQRT: Square root extraction is applied to the input to the AI function block and the result is output (in the range set in OUT_SCALE). This setting is not used for a digitalYEWFLO.

This output mode setting also applies to the scale and unit of indications on the LCD indicator.

Set the time constant of damping in seconds. The setting of PRIMARY_VALUE_FTIME affects not only the ﬂ ow rate but also the totalization. In comparison, the setting of parameter PV_FTIME in an AI function block works as the damping time constant for the AI block’s OUT. As the damping feature of the ﬂ owmeter itself, it is advisable to use PRIMARY_VALUE_FTIME.

This setup is used for zeroing ﬂ ow rate readings in a low ﬂ ow rate area. The value of LOW_ CUT_FLOW (the cutoff level) is set in the same unit as that for PRIMARY_VALUE_RANGE. In comparison, the setting of parameter LOW_CUT in an AI function block works as a low cutoff level setting for the AI block’s OUT. As the low cutoff feature of the ﬂ owmeter itself, it is advisable to use LOW_CUT_FLOW.

Simulation of each AI/DI block can be performed in such a way that the value and status of the input to the block can be set arbitrarily. Use this function for loop checks or the like. Refer to Section 7.3 “Simulation Function. ”

Set the units of data to be displayed on the LCD, and the display refresh cycle. Adjust DISPLAY_ CYCLE to improve legibility such as when used in a low temperature environment causing hard-to-read indications.

Set the 0% and 100% points for calibrations, i.e., the calibration range. The output can be calibrated precisely to the output of a user’s reference device.

APPENDIX 5. INTEGRATOR (IT) BLOCK

A5-1

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.

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

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

The Integrator block is classiﬁ ed into the following ﬁ ve sections for each function:

• Input process section: Determines the input value status, converts the rate and accumulation, and determines the input ﬂ ow direction.

• Adder: Adds the two inputs.

• Integrator: Integrates the result of the adder into the integrated value.

• Output process section: Determines the status and value of each output parameter.

• Reset process section: Resets the integrated values.

IM 01F06F00-01EN

A5-2

A5.2 Input Process Section

When executed, the Integrator block ﬁ rst performs input processing in the order of: “Determining input status”  “Converting Rate or Accum”  “Determining the input ﬂ ow 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.

A5.2.1 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)

Good Irrelevant Irrelevant Good

Bad Irrelevant H (=1) Good

Bad Irrelevant L (=0) Bad

Uncertain H (=1) Irrelevant Good

Uncertain L (=0) Irrelevant Bad

Bit 4 of INTEG_OPTS

(Use Uncertain)

Bit 5* of INTEG_OPTS

(Use Bad)

Status of Input Values

Handled in IT Block

For addition (Refer to APPENDIX 5.3 “Adder”), if the status of an input value is “Bad,” the “Good” value just before the status changed to “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.

A5.2.2 Converting the Rate

The following describes an example of rate conversion. In rate conversion, ﬁ rstly 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.

Standardizes the unit of IN_2 to that of IN_1. Because “lb/s” is converted into “kg/s” in this example, the input 2 value is multiplied by 0.453. (1 lb = 0.453 kg)

A5.2.3 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 conﬁ gure the factor of conversion to the appropriate engineering unit in the PULSE_VAL1 and PULSE_ VAL2 parameters.

A5.2.4 Determining the Input Flow

Direction

The Integrator block also considers the input ﬂ ow direction. Information about the input ﬂ ow 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 ﬂ ow 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. 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.

A5.3 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.

A5.3.1 Status of Value after Addition

A5.4 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. 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.

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.

A5.3.2 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 2 of INTEG_OPTS

(Flow Forward)

HHTOTAL

LLTOTAL

H L FORWARD

L H REVERSE

Bit 3 of INTEG_OPTS

(Flow Reverse)

Adder Options

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. When bit 7 of INTEG_OPTS (Add zero if bad) has been set, if the status of a value after addition is “Bad,” the value after addition (increment) becomes “0.”

Each type of integration is independently run as a function. There are the following four types of integrated values:

The value is used for the ACCUM_TOTAL (expanded parameter) value. The Table A5.1 shows the details of INTEG_TYPE.

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

2. UP_DEM : Counts up from 0 and reset on

demand.

3. DN_AUTO : Counts down with automatic

reset when zero is reached

4. DN_DEM : Counts down from SP and

reset on demand.

5. PERIODIC : Counts up from 0 and is reset

periodically according to CLOCK_PER

6. DEMAND : Counts up from 0 and is reset

on demand

7. PER&DEM : Counts up from 0 and is reset

periodically or on demand

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.
