(See “FISCO Rules”). The safety barrier may include a terminator. More than one field instruments may be connected to the power supply line.

IM 01C22T02-01E

FISCO Rules

The FISCO Concept allows the interconnection of intrinsincally safe apparatus to associated apparatus not specifically examined in such combination. The criterion for such interconnection is that the voltage

(Ui), the current (Ii) 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 (Io) and the power (Po) which can be provided by the associated apparatus (supply unit).

P o P i , U o U i , I o I i

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 5 nF and 10 H respectively.

C i 5nF, L i 10 H

In each I.S. fieldbus segment only one active source, normally the associated apparatus, is allowed to provide the necessary power for the fieldbus system.

The allowed voltage Uo of the associated apparatus used to supply the bus is limited to the range of 14 V dc to 24 V dc. 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.

Supply unit

Trapezoidal or rectangular output characteristic only

Uo = 14...17.5 V (I.S. maximum value)

Io according to spark test result or other assessment. No specification of Lo and Co is required on the certificate or label.

Cable

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

Loop resistance Rc: 15...150

Ω

/km

Inductance per unit length Lc: 0.4...1 mH/km

Capacitance per unit length Cc: 80...200 nF/km

Length of spur cable: max. 30 m (Group IIC and

IIB)

Length of trunk cable: max. 1 km (Group IIC) or 5 km (Group IIB)

2. HANDLING CAUTION

Terminators

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

R = 90...102

Ω

C = 0...2.2 F (0.8...1.2 F is required in operation)

The resistor must be infallible according to IEC 60079-

11.

System evaluations

The number of passive device like transmitters, actuators, hand held terminals 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.

3. ABOUT FIELDBUS

3. ABOUT FIELDBUS

3.1 Outline

Fieldbus is a bi-directional digital communication protocol for field devices, which offers an advancement in implementation technologies for process control systems and is widely employed by numerous field devices.

EJA 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 two AI function blocks, providing the means to implement a flexible instrumentation system.

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 EJA

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

3.2.1 System/network Management VFD

• Sets node addresses and Phisical 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 block

• Manages the status of EJA hardware.

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

(2)Transducer block

• Converts sensor output to pressure signals and transfers to AI function block.

(3)AI1 function block

• Conditions raw data from the Transducer block.

• Outputs differential pressure signals.

• Carries out scaling, damping and square root extraction.

(4)AI2 function block

• Outputs static pressure signals.

(5)PID function block

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

3.4 Wiring System Configuration

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 01C22T02-01E

4. GETTING STARTED

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 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.

• Field devices:

Connect Fieldbus communication type EJA. Two or more EJA 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 material.

• 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

mm 2 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

EJA, 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 EJA. 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.

4-1 IM 01C22T02-01E

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 EJA needs to be installed. Check if host has the following directory under its default DD directory.

594543\0003

(594543 is the manufacturer number of Yokogawa

Electric Corporation, and 0003 is the EJA device number, respectively.)

NOTE

Ensure to use the suitable file for the device.

EJA has two types, one with the standard function blocks and /LC1 with PID/LM function. If the different type CFF is used, some errors may occur at downloading to the device.

F0403.EPS

Figure 4.3 Device Information Sheet Attached to EJA

If no EJA is detected, check the available address range and the polarity of the power supply. If the node address and PD tag are not specified when ordering, default value is factory set. If two or more EJAs are connected at a time with default value, only one EJA will be detected from the host as EJAs have the same initial address. Separately connect each EJA and set a different address for each.

4.5 Reading the Parameters

To read EJA parameters, select the AI1 block of the

EJA from the host screen and read the OUT parameter.

The current selected signal is displayed. Check that

MODE_BLK of the function block and resource block is set to AUTO, and change the signal input and read the parameter again. A new designated value should be displayed.

4-3 IM 01C22T02-01E

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).

4.7 Generation of Alarm

If the host is allowed to receive alarms, generation of an alarm can be attempted from EJA. In this case, set the reception of alarms on the host side. The example using EJA differential pressure transmitter is shown below. EJA’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 first 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 section 5.6.1 Link Object for details.

Since the L0_PRI parameter (index 4029) of the AI1 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 L0_LIM parameter (index 4030) of the AI1 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 10 (meaning 10 kPa) to the limit. Since the differential pressure is almost 0, a lower bound alarm is raised. Check that the alarm can be received at the host. When the alarm is confirmed, transmission of the alarm is suspended.

The above-mentioned items are a description of the simple procedure to be carried out until EJA is connected to Fieldbus. In order to take full advantage of the performance and functionality of the device, it is recommended that it be read together with Chapter 5, which describes how to use the EJA.

4. GETTING STARTED

4-4 IM 01C22T02-01E

5. CONFIGURATION

5. CONFIGURATION

This chapter describes how to adapt the function and performance of the EJA to suit specific applications.

Because multiple devices are connected to Fieldbus, it is important to carefully consider the device requirements and settings when configuring 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 definition

Determines the tag and node addresses for all devices.

(3)Definition 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 sequece each step of this procedure. The use of a dedicated configuration tool significantly simplifies this procedure. Refer to

Appendix 5 when the EJA 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

• 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 instrumentation. EJA 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 bus control function is needed.

• Cable

Used for connecting devices. Refer to “Fieldbus

Technical Information” for details of instrumentation 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 EJA is

16.5 mA. The cable used for the spur must be of the minimum possible length.

5-1

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 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 (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 EJA in the

IM 01C22T02-01E

range of the BASIC device. When the EJA is used as

Link Master, place the EJA in the range of LM device.

Set the range of addresses to be used to the LM device.

Set the following parameters.

5.3 Definition of Combining

Function Blocks

The input/output parameters for function blocks are combined. For the EJA, two AI blocks output parameter (OUT) and PID block are subject to combination.

They are combined with the input of the control block as necessary. Practically, setting is written to the EJA link object with reference to “Block setting” in Section

5.6 for details. It is also possible to read values from the host at proper intervals instead of connecting the

EJA 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 EJA schedule according to the following table. The values in the table are factory-settings.

Addresses

This section describes the steps in the procedure to set

PD Tags and node addresses in the EJA. 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. EJA must be transferred to this state when an

EJA tag or address is changed.

Figure 5.4 Status Transition by Setting PD Tag and Node

Address

EJA has a PD Tag (PT1001) 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 address 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 EJA is 5945430003xxxxxxxx. (The xxxxxxxx at the end of the above device ID is a total of 8 alphanumeric characters.)

5-3 IM 01C22T02-01E

5.5 Communication Setting

To set the communication function, it is necessary to change the database residing in System/network

Management VFD.

5.5.1 VCR Setting

Set VCR (Virtual Communication Relationship), which specifies the called party for communication and resources. EJA has 17 VCRs whose application can be changed, except for the first VCR, which is used for management.

EJA 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 for each parameter may cause inconsistent operation.

5.6.4 Function Block Parameters

Function block parameters can be read from the host or can be set. For a list of the parameters of blocks held by the EJA, refer to “List of parameters for each block of the EJA” in Appendix 1. For PID/LM function option, refer to Appendix 4&5. The following is a list of important parameters with a guide to 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 differential pressure and AI2 block is assigned static pressure, respectively. Do not change this setting.

XD_SCALE:

Scale of input from the transducer block. The calibrated range is factory set (from 0% point to

100% point). Usually, the unit is set in kPa. Changing the unit (can be set only in pressure unit) also causes the unit within the transducer block to be automatically changed. (The unit is automatically changed according to the unit selected by AI1.) Unit index which can be set by XD_SCALE is as shown below.

Table 5.15 Unit Index by XD_SCALE

MPa kPa hPa bar mbar

1132, 1545 (abs), 1546 (gauge)

1133, 1547 (abs), 1548 (gauge)

1136, 1553 (abs), 1554 (gauge)

1137

1138 atm 1140

T0515.EPS

L_TYPE:

Specifies the operation function of the AI block. If set to “Direct”, the input delivered to CHANNEL is directly reflected on OUT. If set to “Indirect”, scaling by XD_SCALE and OUT_SCALE is carried out and is reflected on OUT. If set to “Indirect

SQRT”, after scaling by XD_SCALE, the square root is extracted and the value scaled by

OUT_SCALE is reflected on OUT.

5-8 IM 01C22T02-01E

PV_FTIME:

Sets the time constant of the damping function within AI block (primary delay) in seconds.

OUT_SCALE:

Sets the range of output (from 0% to 100%). The unit can also be set with ease.

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.

5.6.5 Transducer Block Parameters

The transducer block sets functions specific to the measurement of the differential and normal pressure of the EJA. For a list of the parameters of each block of the EJA, refer to “List of parameters for each block of the EJA” in Appendix 1. The following is a list of important parameters with a guide to how to set them.

TERTIARY_VALUE:

Displays the capsule temperature of the EJA.

TERTIARY_VALUE_UNIT:

Sets display unit of temperature at EJA. If set to

1001,

C is used, and if set to 1002,

F is used. The factory default setting is

DISPLAY_MODE:

Sets the unit to be used for LCD display.

1. Engineering Unit (Engr. Unit)

2. %

3. 1/10 @ Engr. Unit

4. 1/100 @ Engr. Unit

5. 1/1000 @ Engr. Unit

6. 1/10000 @ Engr. Unit

7. 1/1000000 @ Engr. Unit

DISPLAY_CYCLE:

Sets the cycle of LCD display in units of function block execution cycles. The factory default setting is

1, but if a low temperature environment makes it difficult to view the display, it is recommended that you set a longer display cycle.

6. IN-PROCESS OPERATION

This chapter describes the procedure performed when changing the operation of the function block of the

EJA in process.

6.1 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.

6.2 Generation of Alarm

6.2.1 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 in 2-second intervals.

2: Simulation started

T0603.EPS

When Simulate En/Disable in Table 6.3 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.

Amplifier Assembly

6.3 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

EJA amplifier. This is to prevent the accidental operation of this function. When this is switched on, simulation is enabled. (See Figure 6.2.) 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.

Explanation

Options which the user may select in the block processing of status

The number of the logical hardware channel that is connected to this I/O block. This information defines the transducer to be used going to or from the physical world.

Determines if the values passed by the transducer block to the AI block may be used directly (Direct) or if the value is in different units and must be converted linearly (Indirect), or with square root (Ind

Sqr Root), using the input range defined by the transducer and the associated output range.

Limit used in square root processing. A value of zero percent of scale is used in block processing if the transducer value falls below this limit, in % of scale. This feature may be used to eliminate noise near zero for a flow sensor.

Description

Computes the control output in accordance with the PID control algorithm.

Converts the change in control output

∆

MV to the manipulated value MV that is to be actually output.

Switches over the direction of control action between direct and reverse, i.e., the direction of changes in the control output depending on the changes in the deviation.

When the bypass is on, the value of the SP is scaled to the range of the OUT and output as the OUT.

Adds the value of the FF_VAL (input to the PID block) to the output from the PID computation.

Equalizes the setpoint SP to the measured value PV.

Limit the value of setpoint SP within the preset upper and lower levels as well as limit the rate of change when the PID block is in Auto mode.

Performs the scaling of the value of TRK_VAL to the range of the OUT and outputs it as the OUT.

Changes the block mode between 8 modes: O/S, IMan, LO, Man, Auto, Cas, RCas, ROut.

Prevents a sudden change in the control output OUT at changes in block mode and at switching of the connection from the control output OUT to the cascaded secondary function block.

Changes the block mode to IMan and suspends the control action when the specified condition is met.

Changes the block mode to Man and aborts the control action.

Changes the block mode to Auto when it is Cas, and continues the control action with the setpoint set by the operator.

Changes the block mode in accordance with the SHED_OPT setting upon a computer failure.

Generates block alarms and process alarms, and performs event updates.

A4.4 PID Computation Details

A4.4.1PV-proportional and -derivative

Type PID (I-PD) Control Algorithm

For PID control, the PID block in an EJA employs the

PV-proportional and PV-derivative type PID control algorithm (referred to as the I-PD control algorithm) in

Auto and RCas mode. The I-PD control algorithm ensures control stability against sudden changes in the setpoint, such as when the user enters a new setpoint value. At the same time, the I-PD algorithm ensures excellent controllability by performing proportional, integral, and derivative control actions in response to changes of characteristics in the controlled process, changes in load, and occurrences of disturbances.

In Cas mode, PV derivative type PID control algorithm

(referred to as the PI-D control algorithm) is employed in order to obtain better performance against the changes in the setpoint. The algorithm is automacially switched by the block according to the mode. A basic form of each algorithm is expressesd in the equation below.

APPENDIX 4. PID Block

A4.5 Control Output

The final control output value, OUT, is computed based on the change in control output

∆

MVn, which is calculated at each control period in accordance with the aforementioned algorithm. The PID block in an EJA performs the velocity type output action for the control output.

A4.5.1 Velocity Type Output Action

The PID block determines the value of the new control output OUT by adding the change in control output calculated in the current control period,

∆

MVn, to the current read-back value of the MV, MV

(BKCAL_IN). This action can be expressed as:

∆

MVn’ =

∆

MVn * (OUT_SCALE. EU100

OUT_SCALE. EU_0) / (PV_SCALE. EU_100

** A transition to Cas, RCas, or ROut requires that initialization of the cascade connection has been completed.

IM 01C22T02-01E

A4.10 Bumpless Transfer

Prevents a sudden change in the control output OUT at changes in block mode (MODE_BLK) and at switching of the connection from the control output OUT to the cascaded secondary function block. The action to perform a bumpless transfer differs depending on the

MODE_BLK values.

A4.11 Setpoint Limiters

Active setpoint limiters that limit the changes in the SP value, differ depending on the block mode as follows.

A4.11.1 When PID Block Is in Auto Mode

When the value of MODE_BLK is Auto, the four types of limiters are in force: high limit, low limit, rate-ofincrease limit, and rate-of-decrease limit.

Setpoint High/Low Limits

• A value larger than the value of SP_HI_LIM cannot be set for SP.

• A value smaller than the value of SP_LO_LIM cannot be set for SP.

Setpoint Rate Limits

The setpoint rate limits are used to restrict the magnitude of changes in the SP value so as to change the SP value gradually towards a new setpoint.

• An increase of the SP value at each execution period

(period of execution in the Block Header) is limited to the value of SP_RATE_UP.

• A decrease of the SP value at each execution period

(period of execution in the Block Header) is limited to the value of SP_RATE_DOWN.

A4.11.2 When PID Block Is in Cas or RCas

Mode

By selecting Obey SP Limits if Cas or RCas in

CONTROL_OPTS (see Section A4.13), the setpoint high/low limits can be put into force also when the value of MODE_BLK is Cas or RCas.

APPENDIX 4. PID Block

A4.12 External-output Tracking

External tracking is an action of outputting the value of the remote output TRK_VAL set from outside the PID block, as illustrated in the figure below. External tracking is performed when the block mode is LO.

TRK_VAL

TRK_SCALE

OUT_SCALE

TRK_IN_D

LO mode

FA0404.EPS

To change the block mode to LO:

(1) Select Track Enable in CONTROL_OPTS.

(2) Set TRK_IN_D to true.

However, to change the block mode from Man to LO,

Track in Manual must also be specified in

CONTROL_OPTS.

A4.13 Measured-value Tracking

Measured-value tracking, also referred to as SP-PV tracking, is an action to equalize the setpoint SP to the measured value PV when the block mode

(MODE_BLK.actual) is Man in order to prevent a sudden change in control output from being caused by a mode change to Auto.

While a cascade primary control block is performing the automatic or cascade control (in the Auto or Cas mode), when the mode of its secondary control block is changed from Cas to Auto, the cascade connection is opened and the control action of the primary block stops. The SP of the secondary controller can be equalized to its cascade input signal CAS_IN also in this case.

The settings for measured-value tracking are made in the parameter CONTROL_OPTS, as shown in the table below.

Equalizes SP to RCAS_IN when MODE_

BLK.target is set to RCas, and to CAS_IN when MODE_BLK.target is set to Cas when the actual mode of the block is IMan,

LO, Man or ROut.

Set the PID block to a direct acting controller.

This enables the external tracking function.

The value in TRK_VAL will replace the value of OUT if TRK_IN_D becomes true and the target mode is not Man.

This enables TRK_VAL to replace the value of OUT when the target mode is Man and TRK_IN_D is true. The actual mode will then be LO.

Sets the value of PV in BKCAL_OUT and

RCAS_OUT, instead of the value of SP.

Puts the setpoint high/low limits in force in the Cas or RCas mode.

Disables the high/low limits for OUT in the

Man mode.

TA0408.EPS

A4.14 Initialization and Manual

Fallback (IMan)

Initialization and manual fallback denotes a set of actions in which a PID block changes mode to IMan

(initialization and manual) and suspends the control action. Initialization and manual fallback takes place automatically as a means of abnormality handling when the following condition is met:

• The quality component of BKCAL_IN.status is Bad.

- OR -

• The quality component of BKCAL_IN.status is

Good (c)

- AND -

The sub-status component of BKCAL_IN.status is

FSA, LO, NI, or IR.

The user cannot manually change the mode to IMan.

A mode transition to IMan occurs only when the condition above is met.

APPENDIX 4. PID Block

A4.15 Manual Fallback

Manual fallback denotes an action in which a PID block changes mode to Man and suspends the control action. Manual fallback takes place automatically as a means of abnormality handling when the following condition is met:

• IN.status is Bad except when the control action bypass is on.

To enable the manual fallback action to take place when the above condition is met, Target to Manual if

BAD IN must be specified beforehand in

STATUS_OPTS.

The table below shows the options in STATUS_OPTS.

Options in

STATUS_OPTS

IFS if BAD IN

Description

Sets the sub-status component of

OUT.status to IFS if IN.status is Bad except when PID control bypass is on.

IFS if BAD CAS IN Sets the sub-status component of

OUT.status to IFS if CAS_IN.status is

Bad.

Use Uncertain as Good

Target to Manual if BAD IN

Target to next permitted mode if BAD CAS IN

Does not regard IN as being in Bad status when IN.status is Uncertain (to prevent mode transitions from being affected when it is Uncertain).

Automatically changes the value of

MODE_BLK.target to MAN when IN falls into Bad status.

Automatically changes the value of

MODE_BLK.target to Auto (or to Man if Auto is not set in Permitted) when

CAS_IN falls into Bad status.

TA0409.EPS

A4.16 Auto Fallback

Auto fallback denotes an action in which a PID block changes mode from Cas to Auto and continues automatic PID control with the user-set setpoint. Auto fallback takes place automatically when the following condition is met:

• IN.status (data status of IN) is Bad except when the control action bypass is on.

To enable the manual fallback action to take place when the above condition is met:

• Target to next permitted mode if BAD CAS IN must be previously specified in STATUS_OPTS.

- AND -

• Auto must be previously set in

MODE_BLK.permitted.

A-20 IM 01C22T02-01E

A4.17 Mode Shedding upon Computer Failure

When the data status of RCAS_IN or ROUT_IN, which is the setting received from a computer as the setpoint SP, falls to Bad while the PID block is running in the RCas or ROut mode, the mode shedding occurs in accordance with the settings in SHED_OPT.

If the RCAS_IN data is not renewed within the time specified by SHED_RCAS in resource block, the data status of RCAS_IN falls to Bad.

A4.17.1 SHED_OPT

The SHED_OPT setting stipulates the specifications of mode shedding as shown below. Only one can be set.

Available Setting for SHED_OPT

Normal shed, normal return

Actions upon Computer Failure

MODE_BLK.target to Auto* 2 .

Shed to Manual, normal return

Sets MODE_BLK.actual to Man, and leaves MODE_BLK.target unchanged.

Shed to Manual, no return

Sets both MODE_BLK.actual and

MODE_BLK.target to Man.

Shed to retained target, normal return

If Cas is in MODE_BLK.target, sets

MODE_BLK.actual to Cas* 1 , and leaves

MODE_BLK.target unchanged.

If Cas is not set in MODE_BLK.target, sets MODE_BLK.actual to Auto* 2 , and leaves MODE_BLK.target unchanged.

Shed to retained target, no return

If Cas is set in MODE_BLK.target, sets both MODE_BLK.actual and

MODE_BLK.target to Cas* 1 .

If Cas is not set in MODE_BLK.target, sets MODE_BLK.actual to Auto* 2 , and

MODE_BLK.target to Cas.

When configuring a simple PID control loop by combining an EJA transmitter with a fieldbus valve positioner that contains an AO block, follow the procedure below to make the settings of the corresponding fieldbus function blocks:

1. Connect the AI block and PID block of the EJA, and the AO block of the valve positioner as shown above.

2. Set MODE_BLK.target of the PID block to O/S, and then set GAIN, RESET, and RATE to appropriate values.

3. Check that the value of MODE_BLK.actual of the

AI block is Auto.

4. Set MODE_BLK.target of the AO block to

CAS|AUTO (meaning "Cas and Auto").

5. Check that the value of BKCAL_IN.status of the

PID block is not Bad.

6. Check that the value of IN.status of the PID block is not Bad.

7. Check that Auto is set in MODE_BLK.permitted of the PID block.

8. Set MODE_BLK.target of the PID block to Auto.

When finishing all steps in order, the PID block and

AO block exchange the respective information and initialize the cascade connection. Consequently, the value of MODE_BLK.actual of the PID block changes to Auto and automatic PID control starts.

APPENDIX 5. Link Master Functions

APPENDIX 5. LINK MASTER FUNCTIONS

A5.1 Link Active Scheduler

A link active scheduler (LAS) is a deterministic, centralized bus scheduler that can control communications on an H1 fieldbus segment. There is only one LAS on an H1 fieldbus segment.

An EJA supports the following LAS functions.

• PN transmission: Identifies a fieldbus device newly connected to the same fieldbus segment. PN is short for Probe

Node.

• PT transmission: Passes a token governing the right to transmit, to a fieldbus device on the same segment. PT is short for Pass Token.

• CD transmission: Carry out a scheduled transmission to a fieldbus device on the same segment. CD is short for

Compel Data.

• Time synchronization: Periodically transmits the time data to all fieldbus devices on the segment and returns the time data in response to a request from a device.

• Live list equalization: Sends the live list data to link masters on the same segment.

• LAS transfer: Transfers the right to be the LAS on the segment to another link master.

A5.2 Link Master

A link master (LM) is any device containing a link active scheduler. There must be at least one LM on a segment.

When the LAS on a segment has failed, another LM on the same segment starts working as the LAS.

A5.3 Transfer of LAS

There are two procedures for an LM to become the LAS:

• If the LM whose value of [V(ST)

V(TN)] is the smallest on a segment, with the exception of the current LAS, judges that there is no LAS on the segment, in such a case as when the segment has started up or when the current

LAS has failed, the LM declares itself as the LAS, then becomes the LAS. (With this procedure, an LM backs up the LAS as shown in the following figure.)

• The LM whose value of [V(ST)

V(TN)] is the smallest on a segment, with the exception of the current LAS, requests the LAS on the same segment to transfer the right of being the LAS, then becomes the LAS.

Description

When a fieldbus segment starts, the LM with the smallest [V(ST)

V(TN)] value within the segment becomes the LAS.

At all times, each LM is checking whether or not a carrier is on the segment.

Transmits a PN (Probe Node) message, and Node Activation

SPDU message to devices which return a new PR (Probe Response) message.

Passes a PT (Pass Token) message to devices included in the live list sequentially, and monitors the RT (Return Token) and final bit returned in reply to the PT.

Transmits a CD (Compel Data) message at the scheduled times.

5 Time synchronization

Domain download server

Supports periodic TD (Time

Distribution) transmissions and transmissions of a reply to a CT

(Compel Time).

Sets the schedule data.

The schedule data can be equalized only when the Domain

Download command is carried out from outside the LM in question.

(The version of the schedule is usually monitored, but no action takes place, even when it changes.)

(3) PrimaryLinkMasterFlagVariable

Explicitly declares the LAS. Writing “true” (0xFF) to this parameter in a device causes that device to attempt to become the LAS. However, a request of writing

“true” to this parameter in a device is rejected if the value of the same parameter in any other device that has a smaller node address within the same segment is true.

(4) LiveListStatusArrayVariable

A 32-byte variable, in which each bit represents the status of whether a device on the same segment is live or not. The leading bit corresponds to the device address 0x00, and final bit to 0xFF. The value of

LiveListStatusArrayVariable in the case where devices having the addresses 0x10 and 0x15 in the fieldbus segment is shown below.

A-29

(5) MaxTokenHoldTimeArray

An 8(64 byte array variable, in which each set of 2 bytes represents the delegation time (set as an octet time) assigned to a device. The delegation time denotes a time period that is given to a device by means of a PT message sent from the LAS within each token circulation cycle.

The leading 2 bytes correspond to the device address

0x00, and the final 2 bytes to the device address 0xFF.

Specify the subindex to access this parameter.

(6) BootOperatFunctionalClass

Writing 1 to this parameter in a device and restarting the device causes the device to start as a basic device.

On the contrary, writing 2 to this parameter and restarting the device causes the device to start as an

LM.

(7) CurrentLinkSettingRecord and

ConfiguredLinkSettingsRecord

CurrentLinkSettingRecord indicates the bus parameter settings currently used. ConfiguredLinkSettingsRecord indicates the bus parameter settings to be used when the device becomes the LAS. Thus, when a device is the LAS, its CurrentLinkSettingRecord and

ConfiguredLinkSettingsRecord have the same values.

A5.6 FAQs

Q1.

When the LAS stops, an EJA does not back it up by becoming the LAS. Why?

A1-1. Is that EJA running as an LM? Check that the value of BootOperatFunctionalClass (index 367) is 2 (indicating that it is an LM).

A1-2. Check the values of V(ST) and V(TN) in all

LMs on the segment and confirm that the following condition is met:

EJA

V(ST)

V(TN) <

Other LMs

V(ST)

V(TN)

Q2.

How can I make an EJA become the LAS?

A2-1. Check that the version numbers of the active schedules in the current LAS and the EJA are the same by reading:

LinkScheduleListCharacteristicsRecord (index

374 for an EJA)

- ActiveScheduleVersion (subindex 3)

A2-2. Make the EJA declare itself as and become the

LAS by writing:

• 0x00 (false) to

PrimaryLinkMasterFlagVariable in the current

LAS; and

• 0xFF (true) to

PrimaryLinkMasterFlagVariable (index 364) in the EJA.

APPENDIX 5. Link Master Functions

Q3.

On a segment where an EJA works as the

LAS, another device cannot be connected.

How come?

A3-1. Check the following bus parameters that indicate the bus parameter as being the LAS for the EJA and the capabilities of being the LAS for the device that cannot be connected:

• V(ST), V(MID), V(MRD) of EJA:

ConfiguredLinkSettingsRecord (index 369)

• V(ST), V(MID), V(MRD) of problematic device: DlmeBasicInfo

Then, confirm that the following conditions are met:

EJA

V(ST) >

V(MID) >

V(MRD) >

Problematic

Device

V(ST)

V(MID)

V(MRD)

A3-2. Check the node address of the problematic device is not included in the V(FUN)+V(NUN) of the EJA.

Q4.

“----” is kept shown on LCD.

The LAS does not exist or is not identified in the fieldbus network, or the EJA is not able to establish communication with the LAS.

A4-1. Check that the LAS is connected on the network. When using the EJA as the LAS, follow the steps described in section A5.3.

A4-2. Adjust the parameters of the LAS to that of the

EJA. Refer to section 5.2 for details.

LAS EJA

V(ST) > V(ST) 4 or above

V(MID) > V(MID) 4 or above

V(MRD) > V(MRD) 12 or above

A4-3. Check that the correct Node Address is used for the EJA. Refer to section 5.2 for details.

Confirm that the Node Address of EJA should be out of the parameters of the LAS of V (FUN)

⬃

V (FUN) V (NUN)

Confirm that the Node Address is not within the default address (0xF8 to 0xFB).

A6.1 Benefits of Software Download

This function enables you to download software to field devices via a F OUNDATION fieldbus to update their software.

Typical uses are to add new features such as function blocks and diagnostics to existing devices, and to optimize existing field devices for your plant.

Concept of Software Downloading

A6.2 Specifications

Steady-state current:

Max. 16.5 mA

Current during FlashROM blanking time:

Max. 24 mA additional to steady-state current

F OUNDATION fieldbus download class:

Class 1

NOTE

Class 1 devices can continue the specified measurement and/or control actions even while software is being downloaded to them. Upon completion of a download, however, the devices will be reset internally to make the new, downloaded software take effect, and this will temporarily halt fieldbus communication and function block executions.

A6.3 Preparations for Software

Downloading

For software downloading, you need to prepare the following:

• Software download tool

• Software binary file for each of the target field devices

For the software download tool, use only the specific program. For details, see the User’s Manual of download tool. For information about updates of software binary files for field devices and how to obtain them, visit the following web site.

http://www.yokogawa.com/fi/fieldbus/download.htm

CAUTION

Avoid linking the software download tool to a fieldbus segment, as this may adversely affect the plant operation.

A-32 IM 01C22T02-01E

NOTE

The download tool can not execute downloading during other system connects to the system/ network management VFD of the device.

APPENDIX 6. SOFTWARE DOWNLOAD

CAUTION

The current dissipation of the target field device increases transitorily immediately after a download due to erasing of the FlashROM’s contents.

Use a fieldbus power supply which has sufficient capacity to cover such increases in feed current.

A6.4 Flow of Software Download

The flowchart below outlines the software download procedure. Although the time taken for the entire procedure varies depending on the size of the field bus device’s software, it will take about 20 minutes for a one-to-one connection between a fieldbus device and download tool, and longer when multiple field devices are connected to the fieldbus.

Start download tool

Select device(s)

Select the software file(s) you want to download.

Carry out download

Transmit the software to the field device(s).

Activate device(s)

Activate the device(s) to start with new software.

FA0602.EPS

Figure 2.

Flow of Software Download Procedure

CAUTION

Carrying out a software download leaves the PD tag, node address, and transducer block calibration parameters that are retained in the nonvolatile memory inside the target device, but may reset other parameters to the defaults (except a minor update that does not change the number of parameters). Hence, where necessary, save the parameters using an engineering tool, parameter setting utility, or the like before carrying out a software download, and then reconfigure the field device(s) after the download. For details, see Section A6.6.

CAUTION

Upon completion of the activation, the target fieldbus device performs resetting internally, which temporarily halts fieldbus communication and function block executions. Be especially careful about a valve positioner; the output air pressure will fall to the minimum level (i.e., zero).

CAUTION

Do not turn off the power to a field device or disconnect the download tool during a download or activation. The device may fail as a result.

NOTE

Be careful about the noise on the fieldbus link.

If the fieldbus is noisy, the downloading may take a very long time or fail.

A6.5 Download Files

Download files have the following filenames (with the filename extension of “.ffd”). Take care to choose the correct download file for the target field device:

“594543” + device family + “_” + device type + “_”

+ domain name + “_” + software name + “_” + software revision + “.ffd”

For example, the name of the download file for an EJA may have the following name:

5945430008_0008_EJA_ORIGINAL_R101.ffd

Refer to A6.11(3) DOMAIN_HEADER about each keyword of the file name.

A-33 IM 01C22T02-01E

The device type is “0008” for an EJA transmitter (with software download capability).

The software name is “ORIGINAL” or “UPDATE.”

The former indicates an original file and the latter an update file. Whenever performing a download to update the device revision, obtain the original file. In general, an addition to the parameters or blocks requires a device revision update.

A6.6 Steps after Activating a

Field Device

When the communication with a field device has recovered after activating the device, check using the download tool that the software revision of the field device has been updated accordingly. The value of

SOFT_REV of the resource block indicates the software revision.

The PD tag, node address, and transducer block calibration parameters that are retained in the nonvolatile memory inside the target device will remain unchanged after a software download. However, after a software update which causes an addition to the block parameters or blocks, or to the system/network management VFD parameters, some parameters may be reset to the defaults, thus requiring parameter setup and engineering again. For details, see the table below.

Also note that a change in the number of parameters or blocks requires the DD and capabilities files corresponding to the new software revision.
