Sensor Circuit: Uo=6.51 V, Io=4 mA, Po=6 mW, Co=34 µF, Lo=500 mH

Note: In the rating 1, the output current of the barrier must

be limited by a resistor “Ra” such that Io=Uo/Ra. In the rating 2 or 3, the output characteristics of the barrier must be the type of trapezoid which are certied as the FISCO model (See “FISCO Rules”). The safety barrier may include a terminator. More than one eld instruments may be connected to the power supply line.

● FISCO Rules

The FISCO Concept allows the interconnection of intrinsincally safe apparatus to associated apparatus not specically examined in such combination. The criterion for such interconnection is that the voltage (Ui), the current (Ii) and the power (Pi) which intrinsically safe apparatus can receive and remain intrinsically safe, considering faults, must be equal or greater than the voltage (Uo, Voc, Vt), the current (Io, Isc, It) and the power (Po) which can be provided by the associated apparatus (supply unit).

Po ≤ Pi, Uo ≤ Ui, Io ≤ Ii

In addition, the maximum unprotected residual capacitance (Ci) and inductance (Li) of each apparatus (other than the terminators) connected to the eldbus must be less than or equal to 5 nF and 10 µH respectively.

Ci ≤ 5nF, Li ≤ 10µH

In each I.S. eldbus segment only one active source, normally the associated apparatus, is allowed to provide the necessary power for the eldbus system. The allowed voltage(Uo, Voc,Vt) of the associated apparatus used to supply the bus cable must be limited to the range of 14 V dc to 17.5 V dc. 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 to a leakage current of 50 µA for each connected device.

Supply unit

Trapezoidal or rectangular output characteristic only

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': 45...200 nF/km. C'=C' line/line + 0.5 C' line/screen, if both lines are oating or C'=C' line/line + C' line/screen, if the screen is connected to one line. Length of spur cable: max. 60 m Length of trunk cable: max. 1 km (Group IIC) or 5 km (Group IIB) Length of splice: max.1m

Terminators

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

R = 90...100 Ω C = 0...2.2 mF

System evaluations

The number of passive device like transmitters, actuators, hand held terminals connected to a single bus segment is not limited due to I.S. reasons. Furthermore, if the above rules are respected, the inductance and capacitance of the cable need not to be considered and will not impair the intrinsic safety of the installation.

● FNICO Rules

The FNICO Concept allows the interconnection of nonincendive eld wiring apparatus to associated nonincendive eld wiring apparatus not specically examined in such combination. The criterion for such interconnection is that the voltage (Vmax), the current (Imax) and the power (Pmax) which nonincendive eld 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 eld 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 20uH respectively.

In each N.I. Fieldbus segment only one active source, normally the associated nonincendive eld wiring apparatus, is allowed to provide the necessary power for the Fieldbus system. The allowed voltage (Uo, Voc or Vt) of the associated nonincendive eld 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 50 µA for each connected device. Separately powered equipment needs galvanic isolation to ensure the nonincendive eld wiring Fieldbus circuit remains passive.

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 eld devices in accordance with the procedures described in this section. The procedures assume that eld 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:

period of within 5 cm (2 inches) may be used. Termination processing depends on the type of device being deployed. For EJX multivariable transmitter, 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.

HOST

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

• Field devices:

Connect Fieldbus communication type EJX multivariable transmitter. Two or more EJX devices or other devices can be connected.

• Host:

Used for accessing eld 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

NOTE

No CHECK terminal is used for Fieldbus EJX multivariable transmitter. Do not connect the eld indicator and check meter.

Before using a Fieldbus conguration tool other than the existing host, conrm 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 conguration 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 EJX multivariable transmitter's.

Symbol Parameter Description and Settings

V (ST) Slot-Time Indicates the time

necessary for immediate reply of the device. Unit of time is in octets (256 μs). Set maximum specication for all devices. For EJX, set a value of 4 or greater.

4.4 Integration of DD

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

594543\000E

(594543 is the manufacturer number of Yokogawa Electric Corporation, and 000E is the EJX multivariable transmitter device number,

respectively.) If this directory is not found, the DD of the EJX910A has not been included. Create the above directory and copy the DD le (0m0n.ffo, 0m0n.sym) (m, n is a numeral) into the directory. "0m" in the le name shows the device revision, and "0n" shows the DD revision. If you do not have the DD or capabilities les, you can download them from our web site:

http://www.yokogawa.com/d/

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

Off-line conguration is possible by using capabilities les.

If no EJX multivariable transmitter is detected, check the available address range and the polarity of the power supply. If the node address and PD tag are not specied when ordering, default value (0xF5) is factory set. If two or more devices are connected at a time with default value, only one device will detected from the host keep the default address and the others’ address will become default address of 0xF8 or later. Separately connect each device and set a different address for each.

EJX has two capabilities levels, "1" and "2".

Select "Capabilities level = 1" when the EJX don't have LC1(PID function) option.

Select "Capabilities level = 2" when the EJX has LC1(PID function) option.

The capabilities level denes the kind and the number of function blocks that can be used.

4.7 Continuous Record of Values

If the host has a function that 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).

4.8 Generation of Alarm

Generation of an alarm can be attempted from EJX multivariable transmitter. Block alarm, Output limit alarm, and Update alarm are informed to the host. When generating alarm, a Link Object and a VCR Static Entry need to be set. For details of Link Object and VCR Static Entry, refer to section 5.6.1 Link object and section 5.5.1 VCR Setting.

This chapter describes how to adapt the function and performance of the EJX multivariable transmitter to suit specic applications. Because multiple devices are connected to Fieldbus, it is important to carefully consider the device requirements and settings when con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 denition

Determines the tag and node addresses for all devices.

(3) De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 conguration tool signicantly simplies this procedure. Refer to Appendix 6 when the EJX multivariable transmitter 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 eld devices necessary for instrumentation. The EJX multivariable transmitter 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 eld 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 sufciently long to connect all devices. For 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. The maximum current consumed (power supply voltage 9 V to 32 V) for the EJX multivariable transmitter 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

5.2 Network Denition

Before connection of devices with Fieldbus, dene 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 denition. Use a hyphen as a delimiter as required.

IM 01C25R03-01E

<5. Conguration>

5-2

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 (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 EJX multivariable transmitter in the range of the BASIC device. When the EJX multivariable transmitter is used as Link Master, place it in the range of the 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

Symbol Parameters Description

V (FUN) First-Unpolled-

Node

V (NUN) Number-of-

consecutiveUnpolled-Node

Indicates the address next to the address range used for the host or other LM device.

Unused address 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 specication of each device for details. Table 5.2 lists EJX specication values.

5.3 Denition 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 EJX 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 EJX 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 EJX schedule according to the following table. The values in the table are factory-settings.

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”

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 EJX be executed at the same time (execution time is overlapped).
