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 allow device performance to be fully exhibited.

3-1

IM 1E7F1-01E

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 fieldbus devices in accordance with the procedures described in this section. The procedures assume that fieldbus devices will be set up on a bench of 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. For ADMAG AE, power supply is required separately. ADMAG AE current consumption does not concern the dedicated power supply for Fieldbus.

• Terminator:

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

• 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 details of the host are explained in the rest of this material.

•Cable:

Used for connecting devices. Refer to “Fieldbus Technical Information” (TI 38K3A01-01E) for details of instrumentation cabling. If the total length of the cable is in a range of 2 to 3 meters for laboratory or other experimental use, the following simplified cable (a twisted pair wire with a cross section of 0.9 mm2 or more and cycle period of within 5 cm (2 inches) may be used.) Termination processing depends on the type of device being deployed. For ADMAG AE, use an M4 screw terminal. Some hosts require a connector.

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

Connect the devices as shown in Figure 4.2. 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.

•Field devices:

Connect Fieldbus communication type ADMAG AE. Two or more ADMAG AE devices or other devices can be connected. Refer to Figure 4.1 Terminal Connection for ADMAG AE.

4. GETTING STARTED

IMPORTANT

Connecting a Fieldbus configuration tool to a loop with its existing host may cause communication data scrambles 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 the 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.

4.3 Bus and ADMAG AE Power ON

Turn on the power of the host, the bus and ADMAG AE. Where the ADMAG AE is equipped with an LCD indicator(option), first all segments are lit, then the segments for a right-most digit are blinking till communication starting. If the indicator is not lit, check the voltage of the power supply for ADMAG AE.

Using the host device display function, check that the ADMAG AE is in operation on the bus. Unless otherwise specified, the following settings are in effect when shipped from the factory.

PD tag: FT1002 Node address: 244 (hexadecimal F4) Device ID: 5945430004xxxxxxxx (xxxxxxxx = a total

of 8 alphanumeric characters)

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

4-2

IM 1E7F1-01E

4. GETTING STARTED

4.4 Integration of DD

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

594543\0004

(594543 is the manufacturer number of Yokogawa Electric Corporation, and 0004 is the ADMAG AE

device number, respectively.) If this directory is not found, DD of ADMAG AE 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.

If you do not have the DD file, you can download it from our web site. Visit the following web site.

http://www.yokogawa.com/fi/fieldbus/download.htm Once the DD is installed in the directory, the name and

attribute of all parameters of the ADMAG AE are displayed.

Off-line configuration is possible using Capability file(CFF).

NOTE

Ensure to use the suitable file for the device. ADMAG AE has two types, /FB-with a AI function block, and /FB/LC1-with PID/LM function. If the different type CFF is used, some errors occur at downloading to the device.

4.7 Generation of Alarm

If the host is allowed to receive alarms, generation of an alarm can be attempted from ADMAG AE. In this case, set the reception of alarms on the host side. ADMAG AE’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 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 1 (the unit is same as XD_SCALE unit) to the limit. Since the flow rate 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 ADMAG AE 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, where describes how to use the ADMAG AE.

4.5 Reading the Parameters

To read ADMAG AE parameters, select the AI block of the ADMAG AE from the host screen and read the OUT parameter. The current flow rate is displayed. Check that MODE_BLOCK 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 recording 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).

4-3

IM 1E7F1-01E

5. CONFIGURATION

This chapter contains information on how to adapt the function and performance of the ADMAG AE to suit specific applications. Because two or more devices are connected to Fieldbus, settings including the requirements of all devices need to be determined. Practically, 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 PD tag and node addresses for all

devices.

(3)Definition of combining function blocks

Determines the method for combination between

each function block.

(4)Setting tags and addresses

Sets the PD Tag and node addresses one by one 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 each step of the procedure in the order given. Using a dedicated configuration tool allows the procedure to be significantly simplified. This section describes the procedure to be assigned for a host which has relatively simple functions. Refer to Appendix 5 when the ADMAG AE is used as Link Master (option).

5.1 Network Design

Select the devices to be connected to the Fieldbus network. The following instruments are necessary for 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). For ADMAG AE,

separate power supply is required. Therefore,

ADMAG AE current consumption does not affect

the dedicated power supply for Fieldbus.

• 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. ADMAG AE 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. For ADMAG AE, separate power supply is required. Thus, ADMAG AE current consumption does not concern the dedicated power supply for Fieldbus. The cable must have the spur in a minimum length with terminators installed at both ends of the trunk.

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.

5-1

IM 1E7F1-01E

5. CONFIGURATION

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 16 to 247 (or hexadecimal 10 to F7) can be set. The device (LM device) with bus control function (Link Master function) is allocated from a smaller address number (16) side, and other devices (BASIC device) without bus control function allocated from a larger address number (247) side respectively. Place ADMAG AE in the range of the BASIC device. When the ADMAG AE is used as Link Master (option), place ADMAG AE in the range of 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 not to allow the address range to become wider, which can lead to exhaustive consumption of Fieldbus communication performance.

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 ADMAG AE specification values.

5.3 Definition of Combining Function Blocks

The input/output parameters for function blocks are combined. For the ADMAG AE, AI block output parameter (OUT) and PID block (option) is subject to combination. They are combined with the input of the control block as necessary. Practically, setting is written to the ADMAG AE 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 ADMAG AE 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 ADMAG AE schedule according to the following table. Enclosed values in the table are factory-settings.

When the control period (macrocycle) is set to more than 4 seconds, set the following interval 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

"starrt of the next block execution"

5.4 Setting of Tags and Addresses

This section describes the steps in the procedure to set PD Tags and node addresses in the ADMAG AE. 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. ADMAG AE must be transferred to this state when an ADMAG AE tag or address is changed.

ADMAG AE has a PD Tag (FT1002) and node address (244, or hexadecimal F4) 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 was cleared will await 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 ADMAG AE is 5945430004xxxxxxxx. (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. ADMAG AE has 16 VCRs whose application can be changed, except for the first VCR, which is used for management.

ADMAG AE 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 respond to requests from a Client (QUB) VCR after the Client initiates connection to the Server successfully. 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 AI Function Block Parameters

AI Function block parameters can be read or set from the host. For a list of the parameters of blocks held by the ADMAG AE, refer to "List of parameters for each block of the ADMAG AE" in Appendix 1. The following is a list of important parameters with a guide to how to set them. For PID/LM function option, refer to Appendix 4 and 5.

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. AI block is assigned flow rate. Do not change this setting.

XD_SCALE:

Scale of input from the transducer block. "0"(0%), "10"(100%), and "m/s" for the unit are factory-set unless otherwise specified. Changing the unit (can be set only in flow rate) also causes the unit within the transducer block to be automatically changed. (The unit is automatically changed according to the unit selected by AI.) Units which can be set by XD_SCALE are shown below.

m/s(1061), ft/s(1067), m m3/min(1348), m3/h(1349), m3/d(1350), L/s(1351), L/min(1352), L/h(1353), L/d(1354), cm3/s(1511), cm3/min(1512), cm3/h(1513), cm3/d(1514), Mgal/s(1451), Mgal/min(1455), Mgal/h(1459), Mgal/d(1366), kgal/s(1450), kgal/min(1454), kgal/h(1458), kgal/d(1462), gal/s(1362), GPM(1363), gal/h(1364), gal/d(1365), mgal/s(1449), mgal/min(1453), mgal/h(1457), mgal/d(1461), kbbl/s(1481), kbbl/min(1485), kbbl/h(1489), kbbl/d(1493), bbl/s(1371), bbl/min(1372), bbl/h(1373), bbl/d(1374), mbbl/s(1480), mbbl/min(1484), mbbl/h(1488), mbbl/d(1492), ubbl/s(1479), ubbl/min(1483), ubbl/h(1487), ubbl/d(1491)

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. “Indirect SQRT” is not used for ADMAG AE.

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.

5.6.5 Transducer Block Parameters

The transducer block sets functions specific to the flow rate measurement of the ADMAG AE. For a list of the parameters of each block of the ADMAG AE, refer to “List of parameters for each block of the ADMAG AE” in Appendix 1. The following is a list of important parameters with a guide to how to set them.

LINE_SIZE:

Sets the size of the flow tube.

SIZE_UNIT:

Sets the unit of the flow tube size.

LOW_MF:

Sets the meter factor of low frequency side.

HIGH_MF:

Sets the meter factor of high frequency side.

For integral type ADMAG AE, these above parameters are set when shipping. Please confirm with data plate. For remote type AE14 converter, please set the above parameters which are shown in the data plate on the combined flow tube.

PRIMARY_VALUE_FTIME:

Sets output time constants. Setting range is 0.1 to 200sec. “ 3sec.” is factory set.

PRIMARY_VALUE_LOWCUT:

Sets low cut range for output. Setting range is 0 to 10%. “ 0%” is factory set. The larger absolute value from EU at 100% or EU at 0% is used for the scale.

DISPLAY_MODE:

Sets the unit to be used for LCD display.

1=Out value 2=% 3=Totalized value 4=Reverse totalized value 5=Diff. totalized value

The factory default setting is 2.

DISPLAY_CYCLE:

Sets the cycle of LCD display. The display cycle is 500ms x (setting). 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 ADMAG AE in process.

6.1 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.

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. (when "1" is set to DISPLAY_CYCLE). An alarm lamp(LED) flashes during alarming.

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: Disabled (standard) 2: Active(simulation)

T0603.EPS

When Simulate En/Disable in Table 6.3 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.

SIMU

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 jumper switch is mounted in the ADMAG AE amplifier. This is to prevent the accidental operation of this function. When jumper is shortcircuited with a pin, simulation is enabled. (See Figure 6.2.) 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.

IMPORTANT

This display board connector is released before simulation jumper switching. Do not pull the amplifier out of the case. After jumper switching, please confirm that the display board connector is not loose.

Summary

Sets PD Tag and each block tag. Up to 32 alphanumeric characters can be set for both tags. Refer to “Tag and address” in Section 5.4.

Sets the range of input from the transducer block corresponding to the 0% and 100% points in operation within the AI1 function block. The calibrated range (0% and 100%) is the factory default setting. Sets the range unit, input value of the 0% point (in case of ADMAG AE, 0), input value of the 100% point (correspond to flow rate span), and the 4 data at the decimal point.

Sets 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 differs from the measurement range. Sets the range unit, input value of the 0% point (lower bound of output scale), input value of the 100% point (upper bound of output scale), and the 4 data at the decimal point.

Selects the operation function of the AI function block. It may be chosen from among Direct, Indirect, and IndirectSQRT. Direct:

Indirect: IndirectSQRT:

*The scale and unit of LCD indicator depend on this setting.

Performs simulation of the AI function block. The input value and status for the calibration range can also be set. It is recommended that this parameter be used for loop checks and other purposes. Refer to “Simulation Function” in Section 6.3.

The output of the transducer block is directly output only via filtering without scaling and square root extraction. (XD_SCALE) Output processed by proportion at the AI function block. (OUT_SCALE) Output processed by square root extraction at the AI function block. IndirectSQRT is not used for ADMAG AE.

Damping time constant setup (PRIMARY_VALUE_FTIME)

Output signal low cut mode setup (PRIMARY_VALUE_LOWCUT)

LCD display setup (DISPLAY_MODE, DISPLAY_CYCLE)

Zero-point adjustment (ZERO_TUNING, AUTO_ZERO)

Sets the time constant of damping function in seconds. The setting of PRIMARY_VALUE_FTIME affects not only flow rate but internal totalization. The totalization is not affected by setting "No Damping" to TOTAL_OPTS of Al function block. PV_FTIME of Al function block is a parameter for damping the value of Al OUT. It is recommended to use PRIMARY_VALUE_FTIME for flowmeter's damping function.

Sets the low cut value in percent against the larger absolute value between EU at 100% and EU at 0%. The hysteresis is 0.5% when the low cut functions and also is released. LOW_CUT of Al function block is a parameter for low cut of Al OUT. It has 1% hysteresis when the low cut is released. Do not make LOW_CUT functioned when flow measuring in reverse direction, or the output is zero at any flow rate because the flow rate is always regarded as under zero. It is recommended to use PRIMARY_VALUE_LOWCUT for flowmeter's low cut function.

Sets the unit to be displayed on the LCD and the display speed. Adjust display speed if a low temperature environment causes a poor LCD display quality.

Performs zero-point adjustment. Zero-point adjustment should be done only when the fluid is filled in the flow tube and the fluid velocity is completely zero.

External-output tracking Mode change Bumpless transfer

Initialization and manual fallback

Manual fallback Auto fallback

Mode shedding upon computer failure

Alarm processing

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

A4.4.1 PV-proportional and -derivative

Type PID (I-PD) Control Algorithm

For PID control, the PID block in an ADMAG AE 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 automatically switched by the block accoridng to the mode. A basic form of each algorithm is expressed in the equation below.

A4.5 Control Output

The final control output value, MV, 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 ADMAG AE 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 MVn by adding the change in control output calculated in the current control period, ∆MVn, to the current read-back value of the MV, MVRB (BKCAL_IN). This action can be expressed as:

∆MVn'= ∆MVn*(OUT_SCALE.EU100-

OUT_SCALE.EU_0)/(PV_SCALE.EU100PV_SCALE.EU_0)

(Direct Acting is False in CONTROL_OPTS)

OUT=BKCAL_IN-∆MVn'

(Direct Acting is True in CONTROL_OPTS)

I-PD Control Algorithm (in Auto/RCas mode)

∆MVn=K ∆PVn+ (PVn-SPn)+ ∆(∆PVn)

∆T

Td ∆T

PI-D Control Algorithm (in Cas mode)

∆MVn=K ∆(PVn-SPn)+ (PVn-SPn)+ ∆(∆PVn)

∆T

Where,

∆MVn = change in control output ∆PVn = change in measured (controlled) value =

PVn - PVn-1

∆T=control period = period_of_execution in

Block Header

K=proportional gain = GAIN (= 100/

proportional band) Ti = integral time = RESET Td = derivative time = RATE

The subscripts, n and n-1, represent the time of sampling such that PVn and PVn-1 denote the PV value sampled most recently and the PV value sampled at the preceding control period, respectively.

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

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 T racking

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 primary 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.

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.

A4.12 External-output Trac king

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.

This parameter allows BYPASS to be set.

Equalizes SP to PV when MODE_BLK.target is set to Man.

Equalizes SP to PV when MODE_BLK.target is set to ROut.

Equalizes SP to PV when actual is set to LO or IMAN.

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.

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.

A4.15 Manual Fallback

Manual fallback denotes an action in which a PID block changes mode to MAN (manual) 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

IFS if BAD CAS IN

Use Uncertain as Good

Target to Manual if BAD IN

Target to next permitted mode if BAD CAS IN

Sets the sub-status component of OUT.status to IFS if IN.status is Bad except when PID control bypass is on.

Sets the sub-status component of OUT.status to IFS if CAS_IN.status is Bad.

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.

Description

TA0409.EPS

A4.16 Auto Fallback

Auto fallback denotes an action in which a PID block changes mode from Cas (cascade) to Auto (automatic) 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.

A4.17 Mode Shedding upon Com-

puter 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 (remote cascade) or ROut (remote output) 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.

*1 The modes to which a PID block can transfer are

limited to those set in MODE_BLK.permitted, and the priority levels of modes are as shown below. In fact, if Normal shed, normal return is set for SHED_OPT, detection of a computer failure causes MODE_BLK.actual to change to Cas, Auto, or Man, whichever is set in MODE_BLK.permitted and has the lowest priority level.

Man Higher priority level Auto Cas RCas ROut Lower priority level

*2 Only when Auto is set as permitted mode.

NOTE: If a control block is connected as a cascade primary block of

the PID block in question, a mode transition of the PID block to CAS occurs in the following sequence due to initialization of the cascade connection: RCas or ROut --> Auto --> Cas.

A4.18 Alarms

There are two kinds of alarms generated by a PID block: block and process alarms.

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 ADMAG AE 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.

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.

To set up an ADMAG AE as a device that is capable of backing up the LAS, follow the procedure below.

NOTE: When changing the settings in an ADMAG AE, add the ADMAG AE to the segment in which an LAS is running. After making changes to the settings, do not turn off the power to the ADMAG AE for at least 60 seconds.

(1) Set the node address of the ADMAG AE. In

general, use an address from 0x10 to [V(FUN) 1].

Long address

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.

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.)

Transmits SPDU messages to LMs to equalize live lists.

Transfers the right of being the LAS to another LM.

See Section A5.5.

(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.

(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 ADMAG AE does

not back it up by becoming the LAS. Why?

A1-1. Is that ADMAG AE 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:

ADMAG AE Other LMs

V(ST)V(TN) < V(ST)V(TN)

Q3. On a segment where an ADMAG AE 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 ADMAG AE and the capabilities of being the LAS for the device that cannot be connected:

• V(ST), V(MID), V(MRD) of ADMAG AE: ConfiguredLinkSettingsRecord (index 369)

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

Then, confirm that the following conditions are met:

ADMAG AE Problematic

Device

V(ST) > V(ST)

V(MID) > V(MID)

V(MRD) > V(MRD)

A3-2. Check the node address of the problematic

device is not included in the V(FUN)+V(NUN) of the ADMAG AE.

Q4. The segments for a right-most digit on LCD

of ADMAG AE are blinking.

Followings are possible causes; No LAS existing on the network or no communication being established between ADMAG AE and LAS.

Q2. How can I make an ADMAG AE become the

LAS?

A2-1. Check that the version numbers of the active

schedules in the current LAS and the ADMAG AE are the same by reading:

LinkScheduleListCharacteristicsRecord

(index 374 for an ADMAG AE)

- ActiveScheduleVersion (subindex 3)

A2-2. Make the ADMAG AE 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 ADMAG AE.

A4-1. Check that LAS is correctly connected to the

network. If ADMAG AE is used as LAS (option), follow the procedures shown in A5.3(1), (2), and (3).)

A4-2. Check that LAS parameters are set so as to meet

the ADMAG AE’s requirement. (See also 5.2 Network Configuration.)

LAS ADMAG AE

V(ST) > V(ST) (4 or greater)

V(MID) > V(MID) (4 or greater)

V(MRD) > V(MRD) (12 or greater)

A4-3. Check that the node address of ADMAG AE is

correctly set. (See also 5.2 Network Configuration.) Not in the range between V(FUN) and V(FUN)+V(NUN) of LAS. Not in the default address (F8 to FB)
