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 (RS)

•Manages the status of YTA hardware.

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

•Outputs temperature signal.

•Carries out scaling, damping and square root extraction.

(4)DI function block

•Limit switch for temperature.

•Accepts the discrete signal from Transducer block and Outputs the discrete signal to show if the temperature exceeds the preset limit.

3. ABOUT FIELDBUS

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.

3-2	IM 01C50T02-01E

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 or HART 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 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 YTA320. Two or more YTA320 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 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 YTA, 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 YTA. Do not connect the field indicator and check meter. Use the instrument with the short-bar being installed between (-) terminal and the CHECK terminal.

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 scrambles resulting in a functional disorder or a system failure.

4-1	IM 01C50T02-01E

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 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 Power ON

Turn on the power of the host and the bus. Where the YTA is equipped with an LCD indicator, first all segments are lit, then the display begins to operate. If the indicator is not lit, check the polarity of the power supply.

Using the host device display function, check that the YTA is in operation on the bus.

The device information, including PD tag, Node address, and Device ID, is described on the sheet attached to YTA. The duplicates of device information are provided on this sheet.

If no YTA 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 YTAs are connected at a time with default value, one YTA will keep the address upon shipment while the other will have a default address as they have the same initial addres. Separately connect each YTA and set a different address for each.

4-2	IM 01C50T02-01E

4.4 Integration of DD

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

594543\0005

(594543 is the manufacturer number of Yokogawa Electric Corporation, and 0005 is the YTA device number, respectively.)

If this directory is not found, DD of YTA 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 or capabilities files, you can download them from our web site. Visit the following web site.

http://www.yokogawa.com/fld

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

Off-line configuration is possible by using capabilities files.

NOTE

Ensure to use the suitable file for the device. YTA has three types, one with the standard function blocks, one with /LC1(additional PID and LAS function) and one with /LC2(additional 2 PIDs and LAS function). If the different type capabilities file is used, some errors may occur at downloading to the device.

4.5 Reading the Parameters

To read YTA parameters, select the AI1 block of the YTA from the host screen and read the OUT parameter. The current temperature which is assign to AI1 block is displayed. Sensor 1 input is assigned to AI1 block upon shipment. Check that actual of MODE_BLOCK of the function block and resource block is set to Auto, and increase the temperature measured by Sensor1 and read the parameter again. A new designated value should be displayed.

4. GETTING STARTED

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).

4.7 Generation of Alarm

If the host is allowed to receive alarms, generation of an alarm can be attempted from YTA. In this case, set the reception of alarms on the host side. YTA’s VCR-6 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, 298, 0, 6, 0”. Refer to section 5.6.1 Link Object for details.

Since the LO_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 LO_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 the value which is apparantely higher than expected measured value to the limit. For example, in case masuering room temperature of 28 C, SET '50( C)' to the limit. Since the measured temperature is lower than the limit, 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 YTA 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 YTA.

5. CONFIGURATION

5.CONFIGURATION

This chapter contains information on how to adapt the function and performance of the YTA 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 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 YTA is used as Link Master.

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). 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 the field devices necessary for instrumentation. YTA 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 YTA is 16.6 mA. 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.

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

5-1	IM 01C50T02-01E

(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 YTA in the range of the BASIC device. When the YTA is used as Link Master, place YTA in the range of LM device. Set the range of addresses to be used to the LM device. Set the following parameters.

Table 5.1 Parameters for Setting Address Range

		device.

		T0501.EPS

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 YTA specification values.

5.3Definition of Combining Function Blocks

The input/output parameters for function blocks are combined. For the YTA, four AI blocks output parameter (OUT), four DI blocks output parameter (OUT_D) 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 YTA 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 YTA 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 YTA schedule according to the following table. Enclosed values in the table are factory-settings.

	Index		Parameters	Setting (Enclosed is

5-2	IM 01C50T02-01E

A maximum of 50 ms is taken for execution of each AI block. A maximum of 30 ms is taken for execution of each DI block, and 100ms for each PID block. For scheduling of communications for combination with the next function block, the execution is so arranged as to start after a lapse of longer than 100 ms. In no case should function blocks of the YTA be executed at the same time (execution time is overlapped).

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

5.4Setting of Tags and Addresses

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

UNINITIALIZED

(No tag nor address is set)

Tag clear		Tag setting

INITIALIZED (Only tag is set)

Address clear		Address setting

SM_OPERATIONAL

(Tag and address are retained, and the function block can be executed.)

F0504.EPS

Figure 5.4 Status Transition by Setting PD Tag and Node Address

YTA has a PD Tag (TT1001) and node address (243, or hexadecimal 0xF3) 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 YTA is 5945430005xxxxxxxx. (The xxxxxxxx at the end of the above device ID is a total of 8 alphanumeric characters.)

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. YTA has 30 VCRs whose application can be changed, except for the first VCR, which is used for management.

YTA 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 and DI 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. CONFIGURATION

5.6.4 Parameters of Transducer Block

The transducer block makes settings for the temperature transmitter-specific functions of the YTA320, such as the temperature input and display settings. See Appendix 1 for a list of all parameters of the YTA320; this section describes only the settings for important parameters.

Note that you can choose “˚C” or “Kelvin” as the unit of temperature. “˚F” or “˚R” can also be selected for a model with the option code /D2.

Mode Setting Parameter

MODE_BLK

Supports O/S and Auto modes. In the O/S mode, the transducer block does not function, as implied by the mode name “Out of Service.”

Parameters Related to Sensor Input

The number “2” enclosed in parentheses appearing in the following parameter names and descriptions indicates that the preceding number “1” should be read as “2” for the cases of sensor 2, respectively.

SENSOR_TYPE_1 (2)

Shows and stipulates the type of sensor connected to sensor input 1 (or 2). The following sensors can be connected.

· Thermocouple: Types B, E, J, K, N, R, S, and T (IEC584), types L and U (DIN43710), and Types W3 and W5 (ASTM E-988)

· 2-/3-/4-wire RTD: Pt100, Pt200, Pt500 (IEC751) JPt100 (JIS), Ni120,

Cu (SAMARC21-4)

·2-/3-/4-wire resistance input

·2-wire DC mV input

IMPORTANT

Whenever 4-wire input is specified for Sensor 1, set ‘Non Connection’ for Sensor 2.

4-wire input cannot be used as Sensor 2.

SENSOR_CONNECTION_1 (2)

Shows and stipulates the number of wires connected to sensor input 1 (or 2). This setting only valid for RTD and resistance input.

5. CONFIGURATION

PRIMARY_VALUE_1 (2)

Shows the value and status of the input from sensor 1 (or 2). The unit set in PRIMARY_VALUE_RANGE_1 (or ..._2) applies to the unit of the value. The damping time constant is set in PRIMARY_VALUE_FTIME_1 (or ..._2).

NOTE

If an input exceeds the range shown-

in PRIMARY_VALUE_RANGE_1(2), the value up to 120% of the range will be output for up er limit side, and -20% of the range will be out

ut for lower limit side. In thie case, the accuracy of the input exceeding the range shall not

be guaranteed.

SECONDARY_VALU

Shows the value and status of the terminal board temperature. The unit of temperature is set in SECONDARY_VALUE_UNIT, and the damping time constant in SECONDARY_VALUE_FTIME.

DIFFERENTIAL_VALUE

Shows the value and status of the difference between 2 inputs [sensor 1 input value minus sensor 2 input value] when 2 sensors are connected. The unit of temperature is set in DIFFERENTIAL_UNIT, and the damping time constant in DIFFERENTIAL_VALUE_FTIME. When there is no connection to sensor 2 input, the status of DIFFERENTIAL_VALUE is Bad and the value is undefined.

AVERAGE_VALUE

Shows the value and status of the average of 2 inputs when 2 sensors are connected. The unit of temperature is set in AVERAGE_UNIT, and the damping time constant in AVERAGE_VALUE_FTIME. When there is no connection to sensor 2 input, the status of AVERAGE_VALUE is Bad and the value is undefined.

BACKUP_VALUE

When 2 sensors are connected, this parameter normally shows the value input from sensor 1, and in case of burnout of sensor 1 (when the backup action becomes active), shows the value input from sensor 2. The unit and damping time constant follow the respective settings for the input currently selected.

5-12	IM 01C50T02-01E

If you want to switch back to select sensor 1 input while the backup action is active after the sensor 1 input recovers, set 1 (Enable) in BACKUP_RETURN_SENSOR1. Because this data is not retained, set 1(Enable) in the parameter every switch back.

When there is no connection to sensor 2 input, the status of BACKUP_VALUE is Bad and the value is undefined.

Parameters Related to Limit Switches

Parameters whose names begin with “LIMSW” store the settings for limit switch signals output to DI function blocks. The transducer block has 4 limit switches numbered from 1 to 4, and these parameters determine the specifications of the respective switches. In the following parameter names and descriptions, read the number “1” as “2,” “3,” or “4” according to the intended limit switch number.

LIMSW_1_VALUE_D

Stores the value and status of limit switch 1.

LIMSW_1_TARGET

Stipulates the value that should be compared with the threshold. PRIMARY_VALUE_1, PRIMARY_VALUE_2, SECONDARY_VALUE, DIFFERENTIAL_VALUE, AVERAGE_VALUE, or BACKUP_VALUE can be chosen.

LIMSW_1_SETPOINT

Stipulates the threshold of switching on limit switch 1.

LIMSW_1_ACT_DIRECTION

Stipulates whether limit switch 1 should work as a high limit switch or low limit switch.

LIMSW_1_HYSTERESIS

Stipulates the hysteresis of limit switch 1.

Parameters Related to Display

For a model with the Integral indicator, the display information can be selected by parameters that have names beginning with “DISPLAY.” For the details of contents to be displayed, refer to section 6.4.

DISPLAY_AI_OUT

Specify an AI block number or numbers to select the AI blocks whose output values should be displayed on the LCD. If two or more AI blocks are selected, the respective values are displayed in turn cyclically.

5. CONFIGURATION

DISPLAY_ERROR

Select whether to display the error code on the LCD. Selecting 1 (INHIBIT) will hide the error code from the LCD even when an error occurs.

DISPLAY_WARNING

Select whether to display the warning code on the LCD. Even if this parameter is set to ‘SHOW’, error code for warning will not be shown when the functions themselves are disabled by parameters WARNING_ENABLE_#.

DISPLAY_ADDRESS

Select whether to display the device address on the LCD.

DISPLAY_CYCLE

Sets the display refresh cycle.

Parameters Related to Warnings

Faults found as a result of self-diagnostics of the YTA320 are categorized into errors and warnings. Warnings can be hidden from the LCD as necessary by changing the values of the parameters below. Refer section 7.4 for the notes on using Warning function.

WARNING_ENABLE_1, (2, 3, 4)

Switches on and off the generation of warnings.

Parameters Related to Input Calibrations

The number “2” enclosed in parentheses appearing in the following parameter names and descriptions indicates that the preceding number “1” should be read as “2” for the cases of sensor 2, respectively.

CAL_STATE_1 (2)

Shows if user adjustment function for Sensor1(2) input is invalid(User Cal off) or valid(User cal on). Setting ‘2(Calibration Exec)’ will allow users to adjust the input.

IMPORTANT

If you changing the sensor type once after making user adjustment function valid, re-do user adjustment or set ‘0(User Cal off)’ to CAL_STATE_1 (2) to make the function off.

5-13	IM 01C50T02-01E

CAL_POINT_HI_1 (2), CAL_POINT_LO_1 (2)

These parameters store the calibrated upper and lower range limit values for sensor input 1 (or 2). To perform a calibration, apply a voltage (for a thermocouple or voltage input) or a resistance (for a RTD or resistance input) between the corresponding input terminals, and write the applied level to these parameters. The values written must meet the following conditions:

CAL_POINT_HI_1 > CAL_POINT_LO_1 CAL_POINT_HI_2 > CAL_POINT_LO_2 The table below shows the recommended input

levels for calibrations.

5.6.5 Parameters of AI Function Block

Parameters of function blocks can be read and written from a host computer. See Appendix 1 for a list of all parameters of the YTA320. For a model incorporating the PID function block and link master feature, see Appendixes 4 and 5. This section describes only the settings for important parameters of each AI block.

MODE_BLK

Supports O/S, Auto, and Manual modes. The AI block does not function in the O/S mode, does not update the measured value in the Manual mode, and updates the measured value in the Auto mode. Normally, set the mode to Auto. Before the YTA320 is shipped from the factory, AI1 and AI2 are set to Auto mode, and AI3 and AI4 to O/S.

NOTE

The CHANNEL of unused blocks are recommended to set to ‘3’ (SECONDARY_VALUE).

CHANNEL

Selects the input to the AI block from the transducer. The table below shows the input value depending on the setting of CHANNEL. Set CHANNEL according to the value you want to input to the AI block.

		(DIFFERENTIAL_VALUE)
5		Average temperature of sensors 1 and 2
		(AVERAGE_VALUE)
	6	Backup temperature (BACKUP_VALUE)

T0517.EPS

XD_SCALE

Stipulates the range of the input from the transducer. The customer-specified range (or the default range if the range was not specified when ordering) is set before the YTA320 is shipped from the factory.

If the unit of the input temperature value is set as mV or ohm in the transducer block and the unit of XD_SCALE is set as a unit of temperature (e.g., °C), or vice versa, the status becomes Uncertain or Bad. It is recommended to set the same unit for the transducer block and AO blocks.

L_TYPE

Stipulates the calculation in the AI block. Setting L_TYPE to:

·“Direct” puts the value that is input to CHANNEL, in OUT as is.

·“Indirect” performs scaling of the input value based on XD_SCALE and OUT_SCALE and puts the scaled value in OUT.

·“IndirectSQRT” performs scaling of the input value based on XD_SCALE, extracts the square root of the scaled value, performs scaling of the square root, and then puts the scaled value in OUT.

PV_FTIME

Stipulates the time constant (in seconds) of the firstorder lag filter inside the AI block.

OUT_SCALE

Stipulates the range of OUT (by setting the upper and lower range limits). The unit can also be set freely. OUT_SCALE is set to 0 to 100% before the YTA320 is shipped from the factory. Change the setting as necessary.

Alarm Priorities: HI_HI_PRI, HI_PRI, LO_PRI,

and LO_LO_PRI

These parameters determine the respective priority levels of the four types of process alarms: HI_HI_ALM, HI_ALM, LO_ALM, and LO_LO_ALM. Only the alarms whose priority level is set to 3 or higher will be transmitted upon occurrence.
