3-1 About Foundation Fieldbus

3-1-1 Outline

Fieldbus is a bi-directional digital communication protocol for field devices, which offers an advancement implementation technologies for process control systems and is widely employed by numerous field devices.

EXA Series 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 three AI function blocks, providing the means to implement flexible instrumentation system.

For information on other features, engineering, design, construction work, startup and maintenance of Fieldbus, refer to http://www.yokogawa.com/fbs/fbs-index.htm.

3-1-2 Internal Structure of EXA

The EXA contains two virtual field devices (VFD) that share the following functions.

3-1-2-1 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)

3-1-2-2 Function Block vFd

(1) resource block

• Manages the status of EXA hardware

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

(2) Transducer block

• Converts sensor output to process values and transfers to AI function block by channels

(3) AI1, AI2, AI3 function block

• Conditions raw data from the Transducer block

• Outputs conditioned process values

• Carries out scaling, damping and square root extraction

3-1-3 Logical Structure of Each Block

Setting of various parameters, node addresses, and PD Tags shown in Figure 3.1 is required before starting operation.

3-1-4 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 Getting started

Fieldbus is fully dependent upon digital communication protocol and differs in operation from conventional 4 to 20 mA transmission 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.

3-2-1 Connection of Devices

3-2-1-1. Fieldbus Preparation

The Foundation Fieldbus® connections and the sensor connections should be made in accordance with figure 3.2 and 3.3. The terminals are of a plug in style for ease of mounting. The EXA 202 FF is provided with two cable glands. The first is used for the electrode wiring as the other is used for the power/foundation® Fieldbus wiring shown in figure 3.2. To open the EXA 202 for wiring:

1. Loosen the four frontplate screws and remove the cover.

2. The terminal strip is now visible.

3. Connect the power supply to the green connector according figure 3.3. Use the gland on the left for this cable.

4. Connect the sensor input, using the gland on the right (see figure 3.2). Switch on the power. Commission the instrument as required or use the default settings.

5. Replace the cover and secure frontplate with the four screws.

3-2-1-2. Cables, terminals and glands

The EXA202 is equipped with terminals suitable for the connection of finished cables in the size range:

0.13 to 2.5 mm (26 to 14 AWG). The glands will form a tight seal on cables with an outside diameter in the

range of 6 to 12 mm (0.24 to 0.47 inches). 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 EXA Fieldbus communication type. Two or more EXA 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 38K03A01-01E) for details of instrumentation cabling. Fieldbus uses twisted pair wires. To meet the Electro Magnetic Interference standards a shielded twisted pair is obligated.

Refer to Yokogawa when making arrangements to purchase the recommended equipment. Connect the devices as shown in Figure 3.4. Connect the terminators at both ends of the trunk, with a mini-

mum length of the spur laid for connection. The polarity of signal and power must be maintained.

Figure 3.4 Cabling

NOTE 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.

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.

3-2-2 Host Setting

To activate Fieldbus, the following settings are required for the host.

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.

Table 3.1 Operation Parameters

Symbol Parameter Description and Settings

V (ST) Slot-Time Set 4 or greater value. V (MID) Minimum-Inter-PDU-Delay Set 4 or greater value. V (MRD) Maximum-Reply-Delay Set so that V (MRD) X V (ST) is 12 or greater V (FUN) First-Unpolled-Node Define the first address that can be used by the host. Set 0x15 or greater. V (NUN) Number-of-consecutive-Unpolled-Node This sets the number of consecutive unpolled nodes. EXA address is

factory-set to 0xEB. Set this address to be within the range of the BASIC device in Figure 3.5.

Figure 3.5 Available Address Range

3-2-3 Bus Power ON

Turn on the power of the host and the bus. First all segments of the display 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 EXA is in operation on the bus. Unless otherwise specified, the following settings are in effect when shipped from the factory.

PH202 SC202 ISC202 DO202 PD tag PH1001 SC1001 ISC1001 DO1001 Node addr. 232 233 234 235 DEV_TYPE 0x0830 0x0831 0x0832 0x0833

If no EXA 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 EXA’s are connected at a time with default value, only one EXA will be detected from the host as EXA’s have the same initial address. Separately connect each EXA and set a different address for each.

IM 12A00A01-61E

Foundation Fieldbus 3-5

3-2-4 Integration of dd

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

594543\DEV_TYPE (594543 is the manufacturer number of Yokogawa Electric Corporation, and DEV_TYPE is the EXA device number, respectively.) If this directory is not found, DD of EXA has not been included. Create the above directory and copy the DD file (0m0n.ffo,0m0n.sym) (m, n is a numeral) (to be supplied separately) into the directory.

Once the DD is installed in the directory, the name and attribute of all parameters of the EXA are displayed. Off-line configuration is possible by using Capability file (CFF).

3-2-5 reading the Parameters

To read EXA parameters, select the AI1 block of the EXA from the host screen and read the OUT parameter. The current process value is displayed. Check that MODE_BLOCK of the function block and resource block is set to AUTO.

3-2-6 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).

3-2-7 Generation of Alarm

If the host is allowed to receive alarms, generation of an alarm can be attempted from EXA. In this case, set the reception of alarms on the host side. EXA’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 first 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 section 3-3-6-1 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 a value higher than the current process value, a 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 EXA 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 of relevant User’s Manual, which describes how to use the EXA.

IM 12A00A01-61E

3-6 Foundation Fieldbus

3-3 Configuration

This chapter contains information on how to adapt the function and performance of the EXA 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 signifi-cantly simplified. This section describes the procedure to be assigned for a host which has relatively simple functions.

3-3-1 Network design

Select the devices to be connected to the Fieldbus network. The following instruments are necessary for operation of Fieldbus.

• 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 field devices necessary for instrumentation. EXA 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.

(EXA 0xEB)

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 to �2 V) for EXA is 26.0 mA. The cable must have the spur in a minimum length with terminators installed at both ends of the trunk.

3-3-2 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 �2 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 20 to 24� (or hexadecimal 0x14 to 0xF�) can be set.

Addresses of devices with Link Master capabilities are set in a low address range smaller than V(FUN). Addresses of basic devices are set in a higher range bigger than V(FUN) + V(NUN). Specify the adress range used by setting the following two parameters in the LM-device:

Table 3.2 Parameters for Setting Address Range

Symbol Parameters Description

V (FUN) First-Unpolled-Node Indicates the address next to the address range used for the host or other

LM device.

V (NUN) Number-of-consecutive-Unpolled-Nodes Unused address range

The devices within the address range written as “Not used” in Figure �.6 cannot be used on a Fieldbus. For other address ranges, the range is periodically checked to identify when a new device is connected. Care must be taken not to allow the address range to become wider, which can lead to exhaustive consumption of Fieldbus communication performance.

Figure 3.6 Available Range of Node Addresses

To ensure stable operation of Fieldbus, determine the operation parameters and set them to the LM devices. While the parameters in Table �.� are to be set, the worst-case values of all the devices to be connected to the same Fieldbus must be used. Refer to the specification of each device for details. Table �.� lists EXA specification values.

maximum specification for all devices. For EXA, set a value of 4 or greater.

V (MRD) Maximum-Reply-Delay The worst case time elapsed until a reply is recorded. The unit is Slot-time; set the value

so that V (MRD) 3V (ST) is the maximum value of the specification for all devices. For EXA, the setting must be a value of 12 or greater.

3-3-3 Definition of Combining Function Blocks

The input/output parameters for function blocks are combined. For the EXA, three AI blocks output parameter (OUT) are subject to combination. They are combined with the input of the control block as necessary. Practically, setting is written to the EXA link object with reference to “Block setting” in Section 3-3-6 for details. It is also possible to read values from the host at proper intervals instead of connecting the EXA 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 EXA schedule according to the following table. Enclosed values in the table are factory-settings.

A maximum of 29 ms is taken for execution of an AI block. Executions of AI blocks should be scheduled sequentially. In no case should two AI function blocks of the EXA be executed at the same time (execution time is overlapped). 29 ms after AI block execution start the out value is available for further processing. Figure 3.8 shows an example of schedule based on the loop shown in Figure 3.7.

There are three states of Fieldbus devices as shown in Figure 3.9, and if the state is other than SM_ OPERATIONAL state, no function block is executed. EXA must be transferred back to this state after a 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.)

Figure 3.9 Status Transition by Setting PD Tag and Node Address

EXA has a PD Tag and node address 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). It is necessary to confirm the device ID in order to correctlyorder to correctly specify the device. The device ID of the EXA is 594543083xxxxxxxxx. (The xxxxxxxxx at the end of the above device ID is a total of 9 alphanumeric characters. The characters displyed on the screen when each instrument is powered on, correspond to the xxxxxxxxx and if necessary, should be recorded.)

3-3-5 Communication Setting

To set the communication function, it is necessary to change the database residing in SM-VFD.

3-3-5-1 VCR Setting

Set VCR (Virtual Communication Relationship), which specifies the called party for communication and resources. EXA has 33 VCRs whose application can be changed, except for the first VCR, which is used for management.

EXA has VCRs of 3 types:

Publisher(-Subscriber) VCR

Publisher-Subscriber VCR’s are designed to link Function Blocks. When a publishing Function Block runs, its output data is stored in the buffer of the Publisher VCR. Then the LAS (LM) sends a CD to this VCR to force it to transfer the data. Subscriber VCRs receive this data and gives this to the subscribing Function Blocks. Typical example is a linkage from an output of an Analog Input (AI) block to the process value input of the PID control block.

Publisher-Subscriber model is one-to-many one-way Communication. Subscribers are able to know whether data is updated since the last publish. This mechanism is important because Data Link Layer transfers data as scheduled regardless the publishing Function Block updates the data in the buffer.

(Client-)Server Model

Client-Server model is universal and used in many communication technologies. An application called “Client” requests another application called “Server” to do a specific action. When the Server finishes the requested action, its result is transferred back to the Client. It is an one-to-one two-way communication. Typical example is a human-machine interface (Client) to read data of a Function Block (Server). The Client sends a Read request to the Server and then the Server sends back the data to the Client. This communication is unscheduled and is handled during the unscheduled interval in the macrocycle. A Client may want to issue many requests at a time. A Client-Server VCR has a queue to store those requests and sends the requests one by one when the node has the token.

Source(-Sink) Model

A Source-Sink VCR is designed to broadcast messages. It is one-to-many one-way communication without any schedule. This model is sometimes called “Report Distribution Model.” A Source VCR transfers a message in the queue to an assigned global address when the device has the token. Sink VCRs are set to the same global address and receive the same message from a Source. Foundation devices use this model for two specific purposes. One is to report alarms or events detected in the Source and the other is to transmit trends of Source Function Blocks. Alarms are acknowledged through a Client-Server VCR. It is desirable for an alarm logger to receive alarms from all devices with just one VCR. A Sink can receive messages from many Sources if the Sources are configured to send messages to the same global address.

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 VCR(s) so that a Subscriber knows the format of published data.

Each VCR has the parameters listed in Table 3.5. Parameters must be changed together for each VCR because modification for each parameter may cause inconsistent operation.

3-3-6-4 Function Block Parameters

Function block parameters can be read from the host or can be set. For a list of the parameters of blocks held by the EXA, refer to “3-6 List of parameters for each block of the EXA”. The following is a list of important parameters with a guide how to set them.

MODE_BLK:

This mode parameter is very important as it gives the state of the block. In O/S (Out_Of_Service) mode the block is out of operation. In this mode it is allowed to update parameters. Manual mode gives the operator the possibility to manually update a selected number of parameters (values, scaling e.g.) in order to test the system. In automatic mode the function block is executed and block parameters are automatically updated. Under normal operating circumstances, set the Auto mode for normal operation. Auto mode is the factory default.

Note: The actual mode is changed by setting the target mode. When the resource block mode is set to

OOS all function blocks in the VFD are set to OOS mode.

CHANNEL:

Transducer blocks convert raw signals into process values. The values are assigned to channels. For the EXA 202 three or four channels are available.

1: pH, 2: Temperature, 3: ORP/rH

Channel value unit

Channel Value Unit

1 primary_value primary_value_range.units 2 secondary_value secondary_value_unit 3 percent_saturation % 4 sensor_current nA

XD_SCALE/OUT_SCALE:

Scaling information is used for two purposes. Display devices need to know the range for bar graphs and trending, as well as the units code. Control blocks need to know the range to use internally as percent of span, so that the tuning constants may remain dimensionless. This is converted back to a number with units by using the range of OUT_SCALE. The AI block has the parameter XD_SCALE to define the units expected from the transducer.

Transducer scaling (XD_SCALE) is applied to the value from the channel to produce the FIELD_VAL in percent. The XD_SCALE units code must match the channel units code. The EXA transmitter does this automatically when the Service Codes are changed. See table 3.18 to 3.21 for the Service codes and their results. If L_TYPE is set to Indirect or Ind Sqr Root, OUT_SCALE determines the conversion from FIELD_VAL to the output. PV and OUT always have identical scaling. OUT_SCALE provides scaling for PV. The PV is always the value that the block will place in OUT if the mode is Auto.

L_TYPE:

Specifies the operation function of the AI block. If set to “Direct”, the input delivered to CHANNEL is directly reflected on OUT. If set to “Indirect”, scaling by XD_SCALE and OUT_SCALE is carried out and is reflected on OUT. If set to “Indirect SQRT”, after scaling by XD_SCALE, the square root is extracted and the value scaled by OUT_SCALE is reflected on OUT.

Example: Channel range is defined as 0 to 100 °C but °F units is required for HOST display. Set the following parameters:

XD_SCALE: EU@0% = 0 °C EU@100% = 100 °C Unit = °C Decimal point = 2 OUT_SCALE: EU@0% = 32 °F EU@100% = 212 °F Unit = °F Decimal point = 2

PV_FTIME:

Sets the time constant of the damping function within AI block (primary delay) in seconds.

Alarm Priority:

Indicates the priority of the process alarm. If a value of 3 or greater is set, an alarm is transmitted. The factory default is 0. Four types of alarm can be set: HI_PRI, HI_HI_PRI, LO_PRI, and LO_LO_PRI.

Alarm Threshold:

Sets the threshold at which a process alarm is generated. The factory default setting is a value that does not generate an alarm. Four types of alarm can be set: HI_LIM, HI_HI_LIM, LO_LIM, and LO_LO_LIM.

3-4 In-process operation

This chapter describes the procedure performed when changing the operation of the function block of the EXA in process.

3-4-1 Mode Transition

When the function block mode is changed to Out_Of_Service, the function block pauses and a block alarm is issued.

When the function block mode is changed to Manual, the function block suspends updating of output values. In this case alone, it is possible to write a value to the OUT parameter of the block for output. Note that no parameter status can be changed.

3-4-3 Simulation Function

The simulation function simulates the input of a function block and lets it operate as if the data was received from the transducer block. It is possible to conduct testing for the downstream function blocks or alarm processes.

A SIMULATE_ENABLE switch is mounted on the FF PCB assembly. This is to prevent the accidental operation of this function. When this is switched on, simulation is enabled. (See Figure 3.13) To initiate the same action from a remote terminal, if REMOTE LOOP TEST SWITCH is written to the SIM_ENABLE_MSG parameter (index 1044) of the resource block, the resulting action is the same as is taken when the above switch is on. Note that this parameter value is lost when the power is turned OFF. In simulation enabled status, an alarm is generated from the resource block, and other device alarms will be masked; for this reason the simulation must be disabled immediately after using this function.

The SIMULATE parameter of AI block consists of the elements listed in Table 3.23 below.

Table 3.23 SIMULATE Parameter

Sub-index Parameters Description

1 Simulate Status Sets the data status to be simulated. 2 Simulate Value Sets the value of the data to be simulated.

3 Transducer Status Displays the data status from the transducer block. It cannot be changed. 4 Transducer Value Displays the data value from the transducer block. It cannot be changed. 5 Simulate En/Disable Controls the simulation function of this block.

1: Simulation disabled (standard) 2: Simulation started

When Simulate En/Disable in Table 3.23 above is set to 2, the applicable function block uses the simulation value set in this parameter instead of the data from the transducer block. This setting can be used for propagation of the status to the trailing blocks, generation of a process alarm, and as an operation test for trailing blocks.

Performs simulation of the AI function block.

The input value and status for the calibration range can also be set.

It is recommended that this parameter be used for loop checks and other purposes.

Refer to “Simulation Function” in Section 3-4-3.

The output of the transducer block is directly output only via filtering without scaling and square root extraction. Output processed by proportion at the AI function block. Output processed by square root extraction at the AI function block.

IMPORTANT

3-7-2 Setting and change of basic parameters

This section describes the procedure taken to set and change the parameters for each block. Obtaining access to each parameter differs depending on the configuration system used. For details, refer to the instruction manual for each configuration system.

Access the block mode (MODE_BLK) of each block.

Set the Target of block mode (MODE_BLK) to Auto, Man or O/S (*Note 2) according to the Write Mode of the parameter to be set or changed.

When “actual mode” has changed (*Note 1),

data associated with the function block

can be maintenanced.

back to Auto (*Note 2) .

Set the Target (*Note 1) of block mode

Do not turn the power OFF immediately after parameter setting. When the parameters are saved to the EEPROM, the redundant processing is executed for an improvement of reliability. Should the power be turned OFF within 60 seconds after setting of parameters, changed parameters are not saved and may return to their original values.

Note 1: Block mode consists of the following four modes that are controlled by the universal parameter that

displays the running condition of each block. Target: Sets the operating condition of the block. Actual: Indicates the current operating condition. Permit: Indicates the operating condition that the block is allowed to take. Normal: Indicates the operating condition that the block will usually take. Note 2: The following are the operating conditions which the individual blocks will take.

Refer to the “List of parameters for each block of the EXA” for details of the Write Mode for each block.

AI Function Block Transducer Block resource Block

Automatic (Auto) Yes Yes Yes Manual (Man) Yes Out of Service (O/S) Yes Yes Yes

3-7-3 Setting the AI Function Blocks

(1) Setting the output scale

As explained in section 3-3-6-4 the OUT_SCALE can used to convert the channel’s value to a different scale. If the channel’s unit (= XD_SCALE unit) is the same as the output unit DO NOT use scaling or let the OUT_SCALE have the same scaling as XD_SCALE. If L_TYPE is set to Indirect or Ind determines the

conversion from FIELD_VAL to the output. PV and OUT always have identical scaling. OUT_

SCALE provides scaling for PV. The PV is always the value that the block will place in OUT if the mode is Auto.

For AI1 set L_TYPE to Direct IM 12A00A01-61E

Sqr Root, OUT_SCALE

Foundation Fieldbus 3-45

With the EXA, the channel values are displayed on the display indicator, independant of the scaling in the AI blocks.

(2) Setting the output mode

Access the L_TYPE parameter. Set the output mode. 1: Direct (Sensor output value) 2: Indirect (Linear output value) 3: IndirectSQRT (Square root extraction output value)

(3) Setting the damping time constant

Access the PV_FTIME parameter. Set the damping time (in seconds).

(4) Simulation

By optionally setting the input value to the calibration range and status, perform simulation of the AI function block.

Access the Simulate Value parameter.

Set an optional input value.

Access the Simulate Status parameter.

Set the status code.

Access the Simulate En/Disable parameter. Set whether Simulation is enabled or disabled. 2: Enabled 1: Disabled

If simulation is enabled, AI block uses Simulate Status and Simulate Value as the input, and if disabled, the AI block uses Transducer Status and Transducer Value as input. Refer to Section 3.4.3 Simulation Function.

3-7-4 Setting the Transducer Block

To access function specifics of the EXA of the transducer block, the DD (Device Description) for EXA needs to have been installed in the configuration tool used. For integration of DD, refer to “Integration of DD” in Section 3-2-4.

4-1. About Profibus

4-1-1 Outline

Profibus is a bi-directional digital communication protocol for field devices, which offers an advancement implementation technologies for process control systems and is widely employed by numerous field devices.

EXA Series Profibus communication type employs the specification standardized by the Profibus organisation, and provides interoperability between Yokogawa devices and those produced by other manufacturers. Profibus comes with software consisting of three AI function blocks, providing the means to implement flexible instrumentation system.

For information on other features, engineering, design, construction work, startup and maintenance of Profibus, refer to the profibus organisation website: www.profibus.com

4-1-2 Internal Structure of EXA

The EXA contains a structured mapping of function blocks. Each function block serves a specific task.

(1) Physical block

• Manages the status of EXA hardware.

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

(2) Transducer block

• Converts sensor input to process values which are transfered to AI function block by channels.

(3) AI1, AI2, AI3 function blocks

• Conditions raw data from the Transducer block.

• Outputs conditioned process values

• Carries out scaling, damping and square root extraction.

4-1-3 Logical Structure of Each BLOCK

4-2 Profibus

Node adress, block tags and contained parameters within a function block are structured in the EXA device as shown in figure 4.1.

4-1-4 Wiring System Configuration

The number of devices (<32) 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.

4-2. Preparation

The EXA 202 Profibus is provided with two cable glands. The first is used for the electrode wiring as the other is used for the power wiring shown in figure 4.3.

To open the EXA 202 for wiring:

1. Loosen the four frontplate screws and remove the cover.

2. The terminal strip is now visible.

3. Connect the power supply according figure 4.4. Use the gland on the left for this cable.

4. Connect the sensor input, using the gland on the right (see figure 4.3). Switch on the power. Commission the instrument as required or use the default settings.

5. Replace the cover and secure frontplate with the four screws.

4-2-1. Cables, terminals and glands

The EXA202 is equipped with terminals suitable for the connection of finished cables in the size range:

0.13 to 2.5 mm (26 to 14 AWG). The glands will form a tight seal on cables with an outside diameter in the

range of 6 to 12 mm (0.24 to 0.47 inches).

4-2-2. Shielding and grounding

Grounding and shielding of the transmitter is necessary for a safe and reliable operation. Please use one of the following schemes (A or B) as these will give proper shielding and grounding. One should pay special attention to instruments that required an external power supply (besides the 9-32V supplied by the bus).

4-3. GETTING STArTEd

Profibus is fully dependent upon digital communication protocol (EN 50170 Volume 2 and IEC 61158 for IS areas, Profibus PA) and differs in operation from the conventional 4 to 20 mA transmission 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.

4-3-1 Connection of devices

The following instruments are required for use with Profibus devices:

• Power supply:

Profibus requires a dedicated power supply. It is recommended that the 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:

Profibus requires two terminators. Refer to the suppliers manual for details of terminators.

• Field devices / slaves

Several field devices or slave devices can be connected to the same link. depending on the power consuption, up to 32 devices can be connected. A maximum of 500mA may be used so the theoretical number of devices is 500mA / Power consumption per device.

• Host / Masters

Used for accessing field devices. A dedicated Master Class 1 host (such as PLC) is used for dedicated cyclic communication. A master Class 2 Host is used for device management puposes such as changing the “ device address” or parameter settings. 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 IEC 61158 for details of instrumentation cabling. Profibus PA uses twisted pair wires up to 1900 metre. To meet the Electro Magnetic Interference standards a shielded twisted pair is obligated.

For applications in intrinsically safe areas, the transmission method defined in IEC 61158-2 is used with PROFIUS-PA The transmission rate in this case is 31.25 kbit/s. DP transmission via RS 485 to IEC 61158-2 is implemented with the network components (DP/PA coupler or DP/PA link)

Connect the devices as shown in Figure 4.7. 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.

Figure 4.7 Cabling

NOTE Before using a Profibus 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.

IM 12A00A01-61E

4-6 Profibus

IMPORTANT

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

4-3-2 Host Setting

To activate Profibus, the following settings are required for the host.

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 settings are made, the modified parameters are not saved and the settings may return to their original values.

For cyclic data communication a GSD file is required. This file contains all necessary information to start this type of communication. Please make sure the gsd file is in the right directory so the information is available to the HOST. Refer to the HOST’s manual for guidance.

For acyclic communication several configuration tools can be used. Each communication tool requires it’s own device driver. We currently support only Siemens Simatic PDM. All parameter lists and methods described in this manual are based on this acyclic communication tool. Please make sure the device driver is in the proper directory. Most HOST systems come with an “install device driver” package which places all required files in the designated folders.

4-3-3 Bus Power ON

Turn on the power of the host and the bus. First all segments of the display 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 EXA is in operation on the bus. Unless otherwise specified, the following settings are in effect when shipped from the factory.

If no EXA is detected, check the available address. Please set all addresses of the devices in advance or separately connect each EXA and set a different address for each. Make sure to note the address after changing it as from this point on the device can only be accessed through this address.

4-3-4 Reading cyclic parameters

In general, slave devices exchange data cyclically with the master (class 1, e.g. PLC). The EXA (slave) gets the data from the sensor, makes some calculations and makes the outcome available through analog input blocks. The controller device (Master) requests for these process values, makes some calculation (PID, ratio) and sends the result to an actuator. The EXA contains three analog input blocks and therefore three Process values for cyclic data transfer.

The master class 1 device gets the information (of the EXA) by consulting the GSD file. A device specific GSD file should be available for each device and should have an unique identifier. All information necessary for cyclic data transfer is described in the GSD file. The YP01078X.gsd file and a bitmap file YP01078X.dib (device independent bitmap) should be placed in dedicated folders (“directories”). Refer to the manual of the Master Class 1 device for these folders. With these files, the Master Class 1 devices are able to start cyclic data transfer.

IM 12A00A01-61E

Profibus 4-7

Beforehandone must configure which information will be exchanged. According with the Profibus-PA Profile 3.01, there are two kinds of configurations possible. The Identifier byte (or short identifier) and the Extended Identifier Format (or long identifier). The EXA supports both kinds of configurations. The user can choose either “Analog Input (short)” or “Analog Input (long)” and will end up with the same result.

The function blocks of the EXA are in a specific order. The configuration of the cyclic data should be done in the same order.

For the EXA. the process values are mapped as follows:

PH202 SC202 ISC202 DO202

slot (1) “AI1” pH SC1 SC1 Dissolved Oxygen slot (2) “AI2” Temperature Temperature Temperature Temperature slot (3) “AI3” ORP/rH SC2 SC2 Percent Saturation

The GSD file of the EXA 202 specifies 3 modules:

;Empty module

Module = “Empty Module” 0x00 1 EndModule

;Modules for Analog Input

Module = “Analog Input (AI)short” 0x94 2 EndModule

;Modules for Analog Input

Module = “Analog Input (AI)long” 0x42,0x84,0x81,0x81 3 EndModule

;--- Description of the module assignment: --; SlotDefinition Slot(1) = “AI1” 3 1,2,3 Slot(2) = “AI2” 3 1,2,3 Slot(3) = “AI3” 3 1,2,3

Examples:

- Configuring the output of the AI block 1 (pH) and the output of AI block 2 (temperature):

“Analog Input (short) “ and “Analog Input (short) “ and “Empty Module” or “0x94, 0x94, 0x00”

- Configuring the output of AI block 1 (pH) only:

“Analog Input (long) “ and “Empty module” and “Empty module” or “0x42, 0x84, 0x81, 0x81, 0x00, 0x00”

Note: Most Master Class 1 devices have an advanced Human Machine Interface and will guide you through

these configurations.

4-3-5 Reading acyclic parameters

Communications occur on a peer-to-peer basis. A cyclic communication services for parametrization, operation, monitoring, alarm/error handling and diagnostics of intelligent devices may be handled in parallel to cyclic transfer.

4-4-4 Methods

The EXA supports methods. A method is a tool to provide the user with a “step by step” user interface for changing settings and providing information.

The following screendumps are derived from a Siemens PDM package.

display and y-t diagram methods

The EXA provides three process values simultaneously. These can be viewed with the display method for bargraphs or with Y-t diagram.

Clock method

This method can be used to set the time of the EXA.

IM 12A00A01-61E

4-20 Profibus

Status method

This method can be used to obtain general information of the EXA like serial number and software revision. This method also provides the user with the current status of the EXA. This can be usefull when the EXA shows errors.

Logbook method

One of the powerfull features of the EXA is the logbook functionality. All events can be stored in one of the two logbooks. To read (upload) the logbook information, simply use this method and the user is provided with all stored events. Each logbook can obtain up to 50 events.

There are 3 LMs on this segment.

APPENdIX 1. LINK MASTEr FUNCTIONS

A1-1 Link Active Scheduler

A link active scheduler (LAS) is a deterministic, centralized bus scheduler that can control communications on an H1 fieldbus segment. There is only one LAS on an H1 fieldbus segment. A EXA202 supports the following LAS functions.

• PN transmission: Identifies a fieldbus device newly connected to the same fieldbus segment. PN is short for Probe Node.

• PT transmission: Passes a token governing the right to transmit, to a fieldbus device on the same segment. PT is short for Pass Token.

• CD transmission: Carry out a scheduled transmission to a fieldbus device on the same segment. CD is short for Compel Data.

• Time synchronization: Periodically transmits the time data to all fieldbus devices on the segment and returns the time data in response to a request from a device.

• Live list equalization: Sends the live list data to link masters on the same segment.

• LAS transfer: Transfers the right to be the LAS on the segment to another link master.

A1-2 Link Master

A link master (LM) is any device containing a link active scheduler. There must be at least one LM on a segment. When the LAS on a segment has failed, another LM on the same segment starts working as the LAS.

A1-3 Transfer of LAS

There are two procedures for an LM to become the LAS:

• If the LM whose value of [V(ST)3V(TN)] is the smallest on a segment, with the exception of the current LAS, judges that there is no LAS on the segment, in such a case as when the segment has started up or when the current LAS has failed, the LM declares itself as the LAS, then becomes the LAS. (With this procedure, an LM backs up the LAS as shown in the following figure.)

• The LM whose value of [V(ST)3V(TN)] is the smallest on a segment, with the exception of the current LAS, requests the LAS on the same segment to transfer the right of being the LAS, then becomes the LAS.

Figure A1-2. Backup of LAS

To set up a EXA202 as a device that is capable of backing up the LAS, follow the procedure below.

NOTE: When changing the settings in a EXA202,

add the EXA202 to the segment in which an LAS is running. After making changes to the settings, do not turn off the power to the EXA202 for at least 60 seconds.

(1) Set the node address of the EXA202.

In general, use an address from 0x14 to [V(FUN) – 1].

(2) In the LAS settings of the EXA202, set the

values of V(ST), V(MRD), and V(MID) to the same as the respective lowest capability values in all the devices within the segment. An example is shown below.

In this case, set SlotTime, MaxResponseTime, and MinInterPduDelay as follows:

When a fieldbus segment starts, the LM with the smallest [V(ST) × V(TN)] value within the segment becomes the LAS. At all times, each LM is checking whether or not a carrier is on the segment.

Transmits a PN (Probe Node) message, and Node Activation SPDU message to devices which return a new PR (Probe Response) message.

Passes a PT (Pass Token) message to devices included in the live list sequentially, and monitors the RT (Return Token) and final bit returned in reply to the PT.

Transmits a CD (Compel Data) message at the scheduled times.

Supports periodic TD (Time Distribution) transmissions and transmissions of a reply to a CT (Compel Time).

Sets the schedule data. The schedule data can be equalized only when the Domain Download command is carried out from outside the LM in question. (The version of the schedule is usually monitored, but no action takes place, even when it changes.)

Transmits SPDU messages to LMs to equalize live lists.

A1-5-2 descriptions for LM Parameters

The following describes LM parameters of a EXA202 transmitter.

NOTE: Do not turn off the power to the EXA202

for 60 seconds after making a change to its parameter settings.

(1) dlmeLinkMasterCapabilitiesvariable

(2) dlmeLinkMasterInforecord

(5) MaxTokenHoldTimeArray

An 8- by 64-byte array variable, in which each set of 2 bytes represents the delegation time (set as an octet time) assigned to a device. The delegation time denotes a time period that is given to a device by means of a PT message sent from the LAS within each token circulation cycle.

The leading 2 bytes correspond to the device address 0x00, and the final 2 bytes to the device address 0xFF. Specify the subindex to access this parameter.

(6) BootOperatFunctionalClass

Writing 1 to this parameter in a device and restarting the device causes the device to start as a basic device. On the contrary, writing 2 to this parameter and restarting the device causes the device to start as an LM.

(3) PrimaryLinkMasterFlagvariable

Explicitly declares the LAS. Writing “true” (0xFF) to this parameter in a device causes that device to attempt to become the LAS. However, a request of writing “true” to this parameter in a device is rejected if the value of the same parameter in any other device that has a smaller node address within the same segment is true.

(4) LiveListStatusArrayvariable

A 32-byte variable, in which each bit represents the status of whether a device on the same segment is live or not. The leading bit corresponds to the device address 0x00, and final bit to 0xFF. The value of LiveListStatusArrayVariable in the case where devices having the addresses 0x10 and 0x15 in the fieldbus segment is shown below.

IM 12A00A01-61E

(7) CurrentLinkSettingrecord and Config-

uredLinkSettingsrecord

CurrentLinkSettingRecord indicates the bus parameter settings currently used. ConfiguredL inkSettingsRecord indicates the bus parameter settings to be used when the device becomes the LAS. Thus, when a device is the LAS, its CurrentLinkSettingRecord and ConfiguredLinkSetti ngsRecord have the same values.

(14) dlmeScheduledescriptor

This parameter exists for the same number as the total number of domains, and each describes the LAS schedule downloaded to the corresponding domain. For the domain to which a schedule has not yet been downloaded, the values in this parameter are all zeros.

(15) domain

Read/write: impossible; get-OD: possible Carrying out the GenericDomainDownload command from a host writes an LAS schedule to the domain.

A1-6 FAQs Q1. When the LAS stops, a EXA202 does not

back it up by becoming the LAS. Why?

A1-1. Is that EXA202 running as an LM? Check

that the value of BootOperatFunctionalClass (index 367) is 2 (indicating that it is an LM).

Q3. On a segment where a EXA202 works as

the LAS, another device cannot be connected. Why?

A3-1. Check the following bus parameters that indi

cate the bus parameter as being the LAS for the EXA202 and the capabilities of being the LAS for the device that cannot be connected:

• V(ST), V(MID), and V(MRD) of EXA202:

ConfiguredLinkSettingsRecord (index 369)

• V(ST), V(MID), and V(MRD) of problematic

device: DlmeBasicInfo

Then, confirm that the following conditions are

met:

EXA202 Problematic Device V(ST) > V(ST)

V(MID) > V(MID) V(MRD) > V(MRD)

A3-2. Check that the node address of the problem

atic device does not lie within either 0x00 to 0x10 or the range of unused (unpolled) node addresses determined by the EXA202’s LM parameter settings, which is 0x00 to 0x10 or V(FUN) to V(FUN) + V(NUM). (Refer to Section 3-3-2, “Network Definition.”)

A1-2. Check the values of V(ST) and V(TN) in all

LMs on the segment and confirm that the following condition is met:

EXA202 Other LMs V(ST) 3 V(TN) < V(ST) 3 V(TN)

Q2. How can I make a EXA202 become the

LAS?

A2-1. Check that the version numbers of the active

schedules in the current LAS and the EXA202 are the same by reading:

LinkScheduleListCharacteristicsRecord

(index 374 for a EXA202)

- ActiveScheduleVersion (subindex 3) A2-2. Make the EXA202 declare itself as and be

come the LAS by writing:

• 0x00 (false) to PrimaryLinkMasterFlagVari able in the current LAS; and

• 0xFF (true) to PrimaryLinkMasterFlagVari able (index 364) in the EXA202.

u Operational Precaution

This document supplements information regarding Operational Precaution. Operate the product carefully based on the following note.

Display on the FieldMate (*)

With using Yokogawa’s FieldMate on the Fieldbus communication of the EXA202 Series instrument, even when unit setting is changed on the instrument, units on AI function blocks on the FieldMate are not changed. Process values on the FieldMate are changed to their new process values for the new units. After changing settings on the instrument, upload the new settings to the FieldMate.

Uploading function on the FieldMate (*)

With using Yokogawa’s FieldMate on the Fieldbus communication of the EXA202 Series instrument, uploading the instrument’s setting to the FieldMate starts with showing an indicator window. On this window, progression of uploading is indicated by a bar and a percentage. Occasionally this percentage on the window doesn’t reach 100%, although uploading is finished. In this case, just close the indicator window.

(*) FieldMate is a communication tool for HART and Fieldbus.
