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.
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.
•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
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. GETTING STARTED
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. GETTING STARTED
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.
4.6 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 28C, 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.
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.
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.
• 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
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.
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
5. CONFIGURATION
(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.

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.

5.3 Definition 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.

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).

5.4 Setting 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.

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 “start
of the next block execution”
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.

5.6.4 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.
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 shownin 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.
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.
5-12
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.
IM 01C50T02-01E
5. CONFIGURATION
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.
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.
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.
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.

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

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:

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.
5-14
· “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.
