XNX Foundation Fieldbus Technical Manual
Introduction
Overview This manual will assist the user in installing, operating, and maintaining the XNX Universal transmitter with the Foundation Fieldbus communication option. It is assumed that the user has a thorough understanding of operating principals for Foundation Fieldbus protocol, the XNX Universal transmitters, as well as the specific host control system in use1. Users should contact the host system vendor directly for configuration questions specific to their systems. Users should review the XNX Universal Transmitter Technical Manual prior to reading this manual.
Product Description Foundation Fieldbus is one of three communication options availalble for the XNX Universal Transmitter. The Foundation Fieldbus option is a fully digital communication protocol conforming to the standards of Fieldbus Foundation. This enables the unit to interface with host control systems offered by manufacturers conforming to Foundation Fieldbus operating standards. As this type of control system platform utilizes a plant-wide communication "bus" network, wiring is accomplished by connecting to the network at any point near the process.
Foundation Fieldbus Foundation Fieldbus is used in process control and monitoring. Process control refers to the monitoring and regulation of continuous processes such as flow, temperature, or tank levels. These types of processes are typically found in places like oil refineries, chemical plants, and paper mills.
Foundation Fieldbus can also be used for monitoring over long distances through distributed control, which means that control is performed by the devices instead of by a monitoring computer. Input, output, and process control devices configured on a Fieldbus network can run independently of a computer system.
Foundation Fieldbus is an all-digital, two-way, multi-drop communication system which brings control algorithms to gas detection instrumentation. Foundation Fieldbus supports digital encoding of data and many types of messages. Unlike many traditional systems, which require a set of wires for each device, multiple Foundation Fieldbus devices can be connected with a single set of wires. Foundation Fieldbus overcomes some of the disadvantages of proprietary networks by providing a standardized network for connecting systems and devices.
1 Illustrations in this manual were made with a Honeywell Experion host controller. Other host controllers are available.

Wiring
A Fieldbus Foundation system replaces the analog 4 to 20 mA current loops common in other field buses with a simple two-wire line running from the control station to the field. This bus cable connects all devices in parallel. The system's information is transmitted digitally. The XNX gas transmitter supports most digital communication protocols (HART, MODBUS, Foundation Fieldbus, etc.) and a discrete output (relay). These are all derived from the primary safety channel, the analogue output (4-20 mA)."
Refer to the Fieldbus Foundation wiring guide (wiringinstallationguide. pdf, available at http://www.fieldbus.org2) before installation. The most common wiring schematics are shown in Figures 1 and 2. Consult the wiring guide for other topologies .

Block Descriptions All Fieldbus devices are arranged in a "block" operating configuration. The Fieldbus Foundation has defined a set of standards that each unit must follow. As a result, block details remain consistent among products and manufacturers. A specially designated level, "Manufacturer Specific Parameters," functions just as the name implies. Here, the Fieldbus Foundation allows manufacturers to add functions specific to their devices. Additional information covering definitions and descriptions can be found at www.fieldbus.org4.
Function Block (Analog Input) The function block is made up of a series of parameters which provide the basis for system control and operation. Standard sets of function blocks have been defined by the Fieldbus Foundation. These blocks are available for input and output communication via the network.
The core duties of the Analog Input (AI) block are to process incoming signals from the sensing element (gas concentration in this case) and to make the data available for use in other function blocks. This data is formatted in user-defined engineering units.
Resource Block Each device has one resource block. The resource block is used to describe characteristics of the individual device. Parameters such as device name, manufacturer, and serial number are located here. There are no linkable parameters located within this block.
Sensor Transducer Block The sensor transducer block contains configuration data specific to the individual device. Data such as sensor type and calibration date are located within this block.
Common Block Operations Each of the blocks within the transmitter share a common set of programming modes. By setting a specific operating mode, the user will be able to dictate the output of the transmitter to the network bus.
Description AUTO
Out Of Service (OOS)
Function
Normal operating mode. All data input, calculations and data output for the block will function
Setting operating mode to OOS disables all function executions by the block.

Specific Commands Resource Block This section outlines common commands that are available within the Resource Block.
WRITE_LOCK The WRITE_LOCK parameter is used to prevent parameter changes from occurring within the device. When enabled, the only accessible command remains WRITE-LOCK so that the parameter may be cleared. When cleared, writing to the device is again enabled. When cleared, an alert is generated by WRITE_ALM to indicate a change was made. The alarm priority corresponds to the WRITE_PRI parameter.
FEATURES_SEL The FEATURES_SEL command is used to turn on and off additional features supported by the device. At this time, REPORTS, SOFTWLOCK, and multi-bit alarming are supported.
Specific Parameters Sensor Transducer Block This section outlines common commands available within the Sensor Transducer Block.
· Information · Test · Calibrate (Zero/Span) · Configuration
This block does not contain parameters that allow engineering units to be modified (modifications can be made through the analog input block). Units within the Sensor Transducer Block automatically track values programmed by the XD_SCALE parameter.
Specific Parameters Analog Input Block These commands that are available within the AI Block.
L_TYPE This parameter is used to define the relationship between the measured process value (Sensor Transducer Block) and the output of the AI Block. XNX supports all linearization types. Setting this parameter to DIRECT will pass the Transducer Block information without modification (i.e., the AI output will be identical to the Transducer Block). Values between the Sensor Transducer Block and the AI Block will remain linear.
XNX Foundation Fieldbus Technical Manual
11
XD_SCALE and OUT_SCALE These parameters are used to set the engineering units and scaling factors associated with the data coming into the AI block, as well as being generated by the AI block. Each of the parameters may be set to 0%, 100%, or to associated engineering units. These parameters are programmed differently, depending on the L_TYPE that is selected.
The supported engineering units are PPM, %LEL, LELm, mg/m3, and %VOL5. To prevent configuration errors from occurring, select ONLY units supported by the device. Engineering units are not writable.
L_TYPE = DIRECT When the desired output of the AI block is the same as the measured variable. The settings are:
XD_SCALE = same as range of process OUT_SCALE = set same as XD_SCALE Example: Process Description Line sees 0-100 %LEL with %LEL as desired output. XD_SCALE 0-100 % LEL OUT_SCALE 0-100 % LEL XD Scale is not writable.
Process Alarms
The OUT data produced by the AI Block is compared to values programmed into the alarms. If a value has been reached, the associated alarm is initiated. Available alarms are:
HI_LIM = High alarm
HI_HI_LIM = High High alarm
LO_LIM = Low alarm
LO_LO_LIM = Low Low alarm
The HI_LIM, HI_HI_LIM, LOW_LIM, LOW_LOW_LIM are used by the AI block in the host.
Status Data Analog Input Block In normal operation, either actual or calculated values are passed from

host control system.

XNX Foundation Fieldbus Technical Manual
the Sensor Transducer Block to the AI Block for further processing. Along with that data, a STATUS condition is also sent. Potential conditions are:
STATUS = GOOD, no problems with hardware or data STATUS = BAD, problems found with either hardware or data passed from Sensor Transducer Block STATUS = UNCERTAIN, The STATUS field is used by the AI block in the host. Simulate Mode Analog Input Block When testing, it is possible to force data out of the analog input block. This procedure could be used to test a control function or to test the operation of the downstream device that received the data. Two methods exist for data output:
Manual Mode Manual mode forces the output data from the AI Block to the desired value. It does not change the status of the STATUS parameter. To initiate manual mode, place the TARGET MODE of the AI Block to MANUAL. The OUT.VALUE can now be modified to reflect the desired output value.
Simulate Mode Simulate mode forces the output data from the AI block to a desired value. It also changes the STATUS parameter to the corresponding value. To initiate Simulate mode: 1. Move the SIM switch on the transmitter to ON. The SIM switch
is located behind the transmitter, above the Foundation Fieldbus connection terminal. The device is now in simulate mode. 2. Set the TARGET MODE to AUTO to change both the OUT.VALUE and OUT.STATUS. 3. Set the SIMULATE_ENABLE_DISABLE parameter to the ACTIVE state. 4. Enter the desired value into the SIMULATE_VALUE parameter to force the output of the OUT.VALUE parameter, along with setting the OUT.STATUS to the correct value.
If any errors occur while performing this procedure, reset the SIM switch. This will clear error conditions and allow the device to resume operation.
