3.1 Outline
Fieldbus is a bi-directional digital communication
protocol for fi eld devices, which offers an
advancement in implementation technologies for
process control systems and is widely employed by
numerous fi eld devices.
The Fieldbus communication type of the
digitalYEWFLO employs the specifi cation
standardized by the Fieldbus FOUNDATION, and
provides interoperability between Yokogawa
devices and those produced by other
manufacturers. Featuring two AI and two DI function
blocks in each, the Fieldbus communication type’s
software enables a fl exible instrumentation system
to be implemented.
For information on other features, engineering,
design, construction work, startup and maintenance
of Fieldbus, refer to “Fieldbus Technical Information”
(TI 38K03A01-01E).
3.2 Internal Structure of
digitalYEWFLO
Each digitalYEWFLO contains two Virtual Field
Devices (VFDs) that share the following functions.
3.2.1 System/Network Management VFD
• Sets node addresses and Physical Device tags
(PD Tag) necessary for communication.
• Controls the execution of function blocks.
• Manages operation parameters and
communication resources (Virtual
Communication Relationship: VCR).
3.2.2 Function Block VFD
(1) Resource (RS) block
• Manages the status of digitalYEWFLO
hardware.
• Automatically informs the host of any detected
faults or other problems.
(2) Transducer (TR) block
• Converts the fl ow sensor output to the
volumetric fl ow rate signal and transfers to an AI
function block (AI1).
• With the option /MV
- Converts temperature sensor output to the
process fl uid temperature and calculates the
fl uid density.
- Calculates the mass fl ow rate from the fl uid
density thus obtained and the volumetric fl ow
rate obtained with the fl ow sensor.
- Transfers these calculation results to AI
function blocks.
• Transfers limit switch signals to DI function
blocks.
(3) AI function blocks (three)
• Output fl owrate and temperature.
• Condition raw data from the TR block.
• Carry out scaling and damping (with a fi rst-
order lag), and allow input simulation.
(4) DI function blocks (two)
• Limit switches for the fl ow rate and temperature
(option /MV).
(5) IT function block (one)
• Accumulate given values.
(6) AR function block (one)
• Calculate input values.
(7) PID function block (option /LC1)
• Performs the PID computation based on the
deviation of the measured value from the
setpoint.

on system design. When constructing systems,
both the basic and overall design must be carefully
considered to achieve optimal performance.
IM 01F06F00-01EN
<4. GETTING STARTED>
4. GETTING STARTED
4-1
Fieldbus is fully dependent upon digital
communication protocol and differs in operation
from conventional 4 to 20 mA transmission
and the BRAIN communication protocol. It is
recommended that novice users use fi eldbus
devices in accordance with the procedures
described in this section. The procedures assume
that fi eldbus devices will be set up on a bench or in
an instrument shop.
4.1 Connection of Devices
The following instruments are required for use with
Fieldbus devices:
• Power supply:
Fieldbus requires a dedicated power supply. It
is recommended that current capacity be well
over the total value of the maximum current
consumed by all devices (including the host).
Conventional DC current cannot be used as is.
• Terminator:
Fieldbus requires two terminators. Refer to
the supplier for details of terminators that are
attached to the host.
• Cable:
Used for connecting devices. Refer to “Fieldbus
Technical Information” (TI 38K03A01-01E) for
details of instrumentation cabling. For laboratory
or other experimental use, a twisted pair cable
two to three meters in length with a cross section
of 0.9 mm2 or more and a cycle period of within
5 cm (2 inches) may be used. Termination
processing depends on the type of device being
deployed. For the digitalYEWFLO, use terminal
lugs applicable to M4 screw terminals. Some
hosts require a connector.
Refer to Yokogawa when making arrangements to
purchase the recommended equipment.
Connect the devices as shown in Figure 4.1.
Connect the terminators at both ends of the
trunk, with a minimum length of the spur laid for
connection.
The polarity of signal and power must be
maintained.

4.2 Host Setting
To activate Fieldbus, the following settings are
required for the host.
IMPORTANT
Do not turn off the power immediately after
setting. When the parameters are saved to the
EEPROM, the redundant processing is executed
for the improvement of reliability. If the power
is turned off within 60 seconds after setting is
made, the modifi ed parameters are not saved
and the settings may return to the original values.

Unless otherwise specifi ed, the following settings
are in effect when shipped from the factory.
If no digitalYEWFLO is detected, check the
available address range. If the node address and
PD Tag are not specifi ed when ordering, default
value is factory set. If two or more digitalYEWFLOs
are connected at a time with default value, only
one digitalYEWFLO will be detected from host as
digitalYEWFLOs have the same initial address.
Connect the digitalYEWFLOs one by one and set a
unique address for each.
NOTE
When using a capabilities fi le (CFF), make sure
you use the right fi le for the intended device. The
digitalYEWFLO is offered in two types in terms of
capabilities:
• General type:
AI function blocks (three), DI function blocks
(two), AR function block (one), and IT
function block (one).
• With the option /LC1: A PID function block

4.4 Integration of DD
If the host supports DD (Device Description), the
DD of the digitalYEWFLO needs to be installed.
Check if host has the following directory under its
default DD directory.
594543 : the manufacturer number of
Yokogawa Electric Corporation
0009 : the device number of digitalYEWFLO
If this directory is not found, the DD for the
digitalYEWFLO has not yet been installed. Create
this directory and copy the DD fi les (0m0n.ffo and
0m0n.sym to be supplied separately where m and
n are numerals) to it. If you do not have the DD fi les
for the digitalYEWFLO, you can download them
from our web site.
Visit the following web site.
http://www.yokogawa.com/fl d/
Once the DD is installed in the directory, the
name and attribute of all parameters of the
digitalYEWFLO are displayed.
Off-line confi guration is possible using the
capabilities fi le.
Using the wrong CFF fi le may result in an
error when downloading the confi gured data
to the device. Also, use the right DD fi les that
accommodate the revision of the intended
device.
4.5 Reading the Parameters
To read digitalYEWFLO parameters, select the AI
block of the digitalYEWFLO from the host screen
and read the OUT parameter. The current fl ow rate
is displayed. Check that MODE_BLK of the function
block and resource block is set to AUTO.
4.6 Continuous Record of Values
If the host has a function of continuously records the
indications, use this function to list the indications
(values). Depending on the host being used, it may
be necessary to set the schedule of Publish (the
function that transmits the indication on a periodic
basis).
IM 01F06F00-01EN
<4. GETTING STARTED>
4.7 Generation of Alarm
If the host is allowed to receive alarms,
generation of an alarm can be attempted from the
digitalYEWFLO. In this case, set the reception of
alarms on the host side. The digitalYEWFLO’s
VCR-7 is factory-set for this purpose. For practical
purposes, all alarms are placed in a disabled status;
for this reason, it is recommended that you fi rst use
one of these alarms on a trial basis. Set the value of
link object-3 (index 30002) as “0, 299, 0, 6, 0”. Refer
to Subsection 5.6.1 “Link Objects” for details.
Since the LO_PRI parameter (index 4029) of the AI
block is set to “0”, try setting this value to “3”. Select
the Write function from the host in operation, specify
an index or variable name, and write “3” to it.
The LO_LIM parameter (index 4030) of the AI block
determines the limit at which the lower bound alarm
for the process value is given. In usual cases, a
very small value is set to this limit. Set smaller value
than 100% value of XD_SCALE (same unit). Since
the fl ow rate is almost 0, a lower bound alarm is
raised. Check that the alarm can be received at the
host. When the alarm is confi rmed, transmission of
the alarm is suspended.

This chapter describes how to adapt the function
and performance of the digitalYEWFLO to suit
specifi c applications. Because multiple devices are
connected to Fieldbus, it is important to carefully
consider the device requirements and settings
when confi guring the system. The following steps
must be taken.
(1) Network design
Determines the devices to be connected to
Fieldbus and checks the capacity of the power
supply.
(2) Network defi nition
Determines the PD tag and node addresses for
all devices.
(3) Defi nition of combining function blocks
Determines how function blocks are combined.
(4) Setting tags and addresses
Sets the PD Tag and node addresses for each
device.
(5) Communication setting
Sets the link between communication
parameters and function blocks.
(6) Block setting
Sets the parameters for function blocks.
The following section describes in sequence each
step of this procedure. The use of a dedicated
confi guration tool signifi cantly simplifi es this
procedure. Refer to APPENDIX 7 “LINK MASTER
FUNCTIONS” when the digitalYEWFLO is used as
Link Master.
5.1 Network Design
Select the devices to be connected to the Fieldbus
network. The following are essential for the
operation of Fieldbus.
• Power supply
Fieldbus requires a dedicated power supply. It
is recommended that current capacity be well
over the total value of the maximum current
consumed by all devices (including the host).
Conventional DC current cannot be used as
power supply.
• Terminator
Fieldbus requires two terminators. Refer to
the supplier for details of terminators that are
attached to the host.
• Field devices
Connect the fi eld devices necessary for
instrumentation. The digitalYEWFLO has passed
the interoperability test conducted by The
Fieldbus Foundation. In order to properly start
Fieldbus, it is recommended that the devices
used satisfy the requirements of the above test.
• Host
Used for accessing fi eld devices. A minimum of
one device with bus control function is needed.
• Cable
Used for connecting devices. Refer to “Fieldbus
Technical Information” (TI 38K03A01-01E) for
details of instrumentation cabling. Provide a
cable suffi ciently long to connect all devices. For
fi eld branch cabling, use terminal boards or a
connection box as required.
First, check the capacity of the power supply.
The power supply capacity must be greater than
the sum of the maximum current consumed by
all devices to be connected to Fieldbus. For the
digitalYEWFLO, the maximum current (power
supply voltage: 9 to 32 VDC) is 15 mA. The cable
used for the spur must be of the minimum possible
length.
5.2 Network Defi nition
Before connection of devices with Fieldbus, defi ne
the Fieldbus network. Allocate PD tags and node
addresses to all devices (excluding such passive
devices as terminators).
The PD tags are the same as conventional
tag numbers assigned to devices. Up to 32
alphanumeric characters may be used for defi nition
of the PD tag for each device. Use hyphens as
delimiters as required.
IM 01F06F00-01EN
<5. CONFIGURATION>
5-2
The node addresses are used to locate devices
for communication purposes. Since a PD tag is too
long a data value, the host substitutes the node
addressed for PD tags in communication. Node
addresses can be set to numbers in a range of
decimal 20 to 247 (hexadecimal 14 to F7). Assign
devices having link master functionality (i.e., LM
devices) from the smallest address number (0x14)
in order, and other devices (i.e., basic devices) from
the largest (0xF7). Assign an address in the range
for basic devices to a digitalYEWFLO. Only when
using a digitalYEWFLO with LM function as an
LM device, assign an address in the range for LM
devices to it. These address ranges are determined
by the following parameters.

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

To ensure stable operation of Fieldbus, determine
the operation parameters and set them to the LM
devices. While the parameters in Table 5.2 are to
be set, the worst-case value of all the devices to
be connected to the same Fieldbus must be used.

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

Setting of Tags and Addresses
This section describes the steps in the procedure
to set the PD tags and node address in the
digitalYEWFLO. There are three states of Fieldbus
devices as shown in Figure 5.4, and if the state
is other than the lowest SM_OPERATIONAL
state, no function block is executed. Whenever
you have changed the PD tag or address of
a digitalYEWFLO, transfer its state to SM_
OPERATIONAL.

In each digitalYEWFLO, the PD tag and node
address are set to “FT1003” and 242 (hexadecimal
F2), respectively, before shipment from the factory
unless otherwise specifi ed. To change only the
node address, clear the address once and then set
a new node address. To set the PD tag, fi rst clear
the node address and clear the PD tag, then set the
PD tag and node address again.
Devices whose node address have been cleared
will await at the default address (randomly chosen
from a range of 248 to 251, or from hexadecimal
F8 to FB). At the same time, it is necessary
to specify the device ID in order to correctly
specify the device. The device ID of the YF100 is
5945430009xxxxxxxx. (The xxxxxxxx at the end
of the above device ID is a total of 8 alphanumeric
characters. Available characters are as follws.)

5.5 Communication Setting
To set the communication function, it is necessary
to change the database residing in SM (System
Management)-VFD.
5.5.1 VCR Setting
Set VCR (Virtual Communication Relationship),
which specifi es the called party for communication
and resources. Each digitalYEWFLO has 33 VCRs
whose application can be changed, except for the
fi rst VCR, which is used for management.
Each digitalYEWFLO has VCRs of four types:
Server (QUB) VCR
A server responds to requests from a host. This
communication needs data exchange. This type
of communication is called QUB (Queued User-
triggered Bidirectional) VCR.
Source (QUU) VCR
A source multicasts alarms or trends to other
devices. This type of communication is called
QUU (Queued User-triggered Unidirectional)
VCR.
Publisher (BNU) VCR
A publisher multicasts outputs of the AI blocks, DI
blocks, AR block, IT block and PID block to other
function blocks. This type of communication
is called BNU (Buffered Network-triggered
Unidirectional) VCR.
Subscriber (BNU) VCR
A subscriber receives output of another function
block(s) by AR block, IT block and PID block.
Each VCR has the parameters listed in Table 5.4.
Parameters must be changed together for each
VCR because modifi cation for each parameter may
cause a contradiction.

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