2. HANDLING CAUTIONS

 FNICO Rules

The FNICO Concept allows the interconnection of
nonincendive field wiring apparatus to associated
nonincendive field wiring apparatus not specifically
examined in such combination. The criterion for such
interconnection is that the voltage (Vmax), the current
(Imax) and the power (Pmax) which nonincendive field
wiring apparatus can receive and remain nonincendive,
considering faults, must be equal or greater than the
voltage (Uo, Voc or Vt), the current (Io, Isc or It) and
the power (Po) which can be provided by the associ­ated nonincendive field wiring apparatus (supply unit).
In addition the maximum unprotected residual capaci­tance (Ci) and inductance (Li) of each apparatus (other
than terminators) connected to the Fieldbus must be
less than or equal to 5nF and 10uH respectively.

In each N.I. Fieldbus segment only one active source,
normally the associated nonincendive field wiring
apparatus, is allowed to provide the necessary power
for the Fieldbus system. The allowed voltage (Uo, Voc
or Vt) of the associated nonincendive field wiring
apparatus used to supply the bus cable must be limited
to the range 14Vdc to 17.5Vdc. All other equipment
connected to the bus cable has to be passive, meaning
that the apparatus is not allowed to provide energy to
the system, except a leakage current of 50É A for each
connected device. Separately powered equipment needs
galvanic isolation to ensure the nonincendive field
wiring Fieldbus circuit remains passive.

Cable

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

Loop resistance R': 15...150 Ω/km
Inductance per unit length L': 0.4...1 mH/km

Capacitance per unit length C': 80....200 nF/km

C' =C' line/line+0.5 C' line/screen, if both lines are
floating or C' = C' line/line + C'line/screen, if
thescreen is connected to one line.
Length of spur cable: max. 30 m
Length of trunk cable: max. 1 km
Length of splice: max = 1 m

Terminators

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

R= 90...100 Ω

C = 0 ....2.2 uF

3.1 Outline

Fieldbus is a widely used bi-directional digital commu­nication protocol for field devices that enable the
simultaneous output to many types of data to the
process control system.

The EJX910A Fieldbus communication type employs
the specification standardized by The Fieldbus Founda­tion, and provides interoperability between Yokogawa
devices and those produced by other manufacturers.
Fieldbus comes with software consisting of five AI
function blocks that enable the flexible implementation
of systems.

For information on other features, engineering, design,
construction work, startup and maintenance of
Fieldbus, refer to “Fieldbus Technical Information” (TI
38K03A01-01E).

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 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 in an
instrument shop.

4.1 Connection of Devices

The following 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 EJX910A.
Two or more EJX devices or other devices can be
connected.

• Host:

Used for accessing field devices. A dedicated host
(such as DCS) is used for an instrumentation line
while dedicated communication tools are used for
experimental purposes. For operation of the host,
refer to the instruction manual for each host. No
other details on the host are given in this manual.

•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
EJX910A, 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.

Before using a Fieldbus configuration tool other than
the existing host, confirm it does not affect the loop
functionality in which all devices are already installed
in operation. Disconnect the relevant control loop from
the bus if necessary.

IMPORTANT

Connecting a Fieldbus configuration tool to a
loop with its existing host may cause communi­cation data scrambling resulting in a functional
disorder or a system failure.

4.2 Host Setting

To activate Fieldbus, the following settings are
required for the host. Set the available address range to
cover the address set for EJX910A’s.

IMPORTANT

Do not turn off the power immediately after
setting. When the parameters are saved to the
EEPROM, the redundant processing is executed
for an improvement of reliability. If the power is
turned off within 60 seconds after setting is
made, the modified parameters are not saved
and the settings may return to the original
values.

5. CONFIGURATION

5. CONFIGURATION

This chapter describes how to adapt the function and
performance of the EJX910A to suit specific applica­tions. Because multiple devices are connected to
Fieldbus, it is important to carefully consider the
device requirements and settings when configuring the
system. The following steps must be taken.

(1)Network design

Determines the devices to be connected to Fieldbus
and checks the capacity of the power supply.

(2)Network definition

Determines the tag and node addresses for all
devices.

(3)Definition of combining function blocks

Determines how function blocks are combined.

(4)Setting tags and addresses

Sets the PD Tag and node addresses for each device.

(5)Communication setting

Sets the link between communication parameters
and function blocks.

(6)Block setting

Sets the parameters for function blocks.

The following section describes in sequence each step
of this procedure. The use of a dedicated configuration
tool significantly simplifies this procedure. Refer to
Appendix 6 when the EJX910A 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 instrumenta-

tion. The EJX910A 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 the 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 the
EJX910A is 15 mA (24 mA in Software download
operation). The cable used for the spur must be of the
minimum possible length.

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 is.

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 this data is too long
for a PD Tag, the host uses the node address in place
of the PD Tag for communication. A range of 20 to
247 (or hexadecimal 14 to F7) can be set. The device

5. CONFIGURATION

(LM device) with bus control function (Link Master
function) is allocated from a smaller address number
(20) side, and other devices (BASIC device) without
bus control function allocated from a larger address
number (247) side respectively. Place the EJX910A in
the range of the BASIC device. When the EJX910A is
used as Link Master, place the EJX910A in the range

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 to keep the unused device range as
narrow as possible so as to lessen the load on the
Fieldbus.

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 EJX910A
specification values.

5.3 Definition of Combining Function Blocks

The input/output parameters for function blocks are
combined. As required, they can be combined with the
input of the control block. The setting is written to the
EJX910A link object. See “Block setting” in Section

5.6 for the details. It is also possible to read values

from the host at proper intervals instead of connecting
the EJX910A 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 EJX910A schedule
according to the following table. The values in the
table are factory-settings.

5. CONFIGURATION

A maximum of 30 ms is taken for execution of AI
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 30 ms.
In no case should function blocks of the EJX910A 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.

5.4 Setting of Tags and Addresses

This section describes the steps in the procedure to set
PD Tags and node addresses in the EJX910A. 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. EJX910A must be transferred to this state
when an EJX910A tag or address is changed.

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

EJX910A has a PD Tag (FT2001) and node address
(245, or hexadecimal F5) that are set upon shipment
from the factory unless otherwise specified. To change
only the node address, clear the address once and then
set a new node address. To set the PD Tag, first clear
the node address and clear the PD Tag, then set the PD
Tag and node address again.

Devices whose node addresses have been cleared will
have the default address (randomly chosen from a
range of 248 to 251, or from hexadecimal F8 to FB).
At the same time, it is necessary to specify the device
ID in order to correctly specify the device. The device
ID of the EJX910A is 594543000Exxxxxxxx. (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. EJX910A has 33 VCRs whose application
can be changed, except for the first VCR, which is
used for management.

EJX910A 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 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).

A Server VCR is capable to responding to requests
from a Client (QUB) VCR after the Client successfully
initiates connection to the Server. A Source VCR
transmits data without established connection. A Sink
(QUU) VCR on another device can receive it if the
Sink is configured so. A Publisher VCR transmits data
when LAS requests so. An explicit connection is
established from Subscriber (BNU) VCR(s) so that a
Subscriber knows the format of published data.

Each VCR has the parameters listed in Table 5.4.
Parameters must be changed together for each VCR
because modification of individual parameters may
cause inconsistent operation.

following 4 types are used
for EJX.
0x32: Server (Responds to

requests from host.)

0x44: Source (Transmits

alarm or trend.)

0x66: Publisher (Sends

block output to other
blocks.)

0x76: Subscriber (Receives

output of other blocks.)

Sets the local address to
specify VCR in EJX. A range
of 20 to F7 in hexadecimal.

Sets the node address of the
called party for
communication and the
address (DLSAP or DLCEP)
used to specify VCR in that
address. For DLSAP or
DLCEP, a range of 20 to F7
in hexadecimal is used.
Addresses in Subindex 2
and 3 need to be set to the
same contents of the VCR
as the called party (local and
remote are reversed).

Specifies the quality of
communication. Usually, one
of the following types is set.
0x2B: Server
0x01: Source (Alert)
0x03: Source (Trend)
0x91: Publisher/Subscriber

To establish connection for
communication, a maximum
wait time for the called
party's response is set in
ms. Typical value is 60
secounds (60000).

For request of data, a
maximum wait time for the
called party's response is
set in ms. Typical value is
60 secounds (60000).

Specifies maximum DL
Service Data unit Size
(DLSDU). Set 256 for Server
and Trend VCR, and 64 for
other VCRs.

Specifies whether
connection is monitored. Set
TRUE (0xff) for Server. This
parameter is not used for
other communication.
