environments. The fieldbus environment is the base level group of digital networks in the
hierarchy of plant networks.

The fieldbus retains the desirable features of the 4–20 mA analog system, including a
standardized physical interface to the wire, bus-powered devices on a single pair of wires,
and intrinsic safety options. In addition, it enables the following capabilities:

 Increased capabilities due to full digital communications

 Reduced wiring and wire terminations due to multiple devices on one pair of wires

 Increased selection of suppliers due to interoperability

 Reduced loading on control room equipment with the distribution of some control

and input/output functions to field devices

 Speed options for process control and manufacturing applications.

1.3 System description

The Rosemount 8800D Vortex Flowmeter with FOUNDATION fieldbus consists of a meter
body and transmitter. It measures volumetric flow rate by detecting the vortices created by
a fluid passing by the shedder bar.

Reference Manual

00809-0100-4772, Rev FA

The meter body is installed in-line with process piping. A sensor is located at the end of the
shedder bar and creates an alternating sine wave signal due to the passing vortices. The
transmitter measures the frequency of the signal and converts it into a flowrate.

This manual is designed to assist in the installation and operation of the flowmeter.

This product is intended to be used as a flowmeter for liquid, gas, or steam
applications. Any use other than for which it was intended may result in serious injury or
death.

2.4 Commissioning

Commissioning the flowmeter consists of verifying the transmitter configuration and
operation. Typically this should be done before the flowmeter is installed in the application
environment. In most cases, the user-supplied variables are pre-configured in the
transmitter at the factory, so the meter is ready to use upon arrival at the end user
installation.

Configuration may be required if:

 Any configuration variables have changed.

 A replacement transmitter is being installed.

To commission, connect power to the device and connect a Field Communicator or
Foundation Fieldbus host system to the signal loop.

1. Verify the device powers up and communicates with the Field Communicator or
host system.

2. Verify transmitter configuration parameters. Following are typical parameters to
check:

2.5 General block information

Reference information on the process control function blocks can be found in the Function
Block manual document number 00809-0100-4783.

2.5.1 Modes of operation

The Resource, Transducer, and all other function blocks in the device have modes of
operation. These modes govern the operation of the block. Every block supports both
automatic (AUTO) and out of service (OOS) modes. Other modes may also be supported.

For the procedures described in this manual, it will be helpful to understand the following
modes:

AUTO

The functions performed by the block will execute. If the block has any outputs, these will
continue to update. This is typically the normal operating mode.

Out of Service (OOS)

Configuration and Operation

March 2016

The functions performed by the block will not execute. If the block has any outputs, these
will typically not update and the status of any values passed to downstream blocks will be
“BAD”. To make changes to the configuration of the block, change the mode of the block to
OOS. When the changes are complete, change the mode back to AUTO.

MAN

In this mode, variables that are passed out of the block can be manually set for testing or
override purposes.

Other types of modes

Other types of modes are Cas, RCas, ROut, IMan and LO. Some of these may be supported
by different function blocks in the flowmeter. For more information, see the Function Block
manual, document 00809-0100-4783.

Note

When an upstream block is set to OOS, the output status of all downstream blocks will be
affected. The figure below depicts the hierarchy of blocks.

Configuration and Operation

Changing modes

To change the operating mode, set the MODE_BLK.TARGET to the desired mode. After a
short delay, the parameter MODE_BLOCK.ACTUAL should reflect the mode change if the
block is operating properly.

Permitted modes

It is possible to prevent unauthorized changes to the operating mode of a block. To do this,
configure MODE_BLOCK.PERMITTED to allow only the desired operating modes. It is
recommended to always select OOS as one of the permitted modes.

2.5.2 Block instantiation

The Rosemount 8800D Device Revision 10 supports block instantiation. Previous device
revisions do not support block instantiation. When a device supports block instantiation,
the number of blocks and block types can be defined to match specific application needs.
The number of blocks that can be instantiated is only limited by the amount of memory
within the device and the block types that are supported by the device. Instantiation does
not apply to standard device blocks like the Resource, Sensor Transducer, Analog Input, and
PID Blocks.

By reading the parameter “FREE_SPACE” in the Resource Block you can determine how
many blocks you can instantiate. Each block that you instantiate takes up 4.5573% of the
“FREE_SPACE”.

Block instantiation is done by the host control system or configuration tool, but not all hosts
are required to implement this functionality. Refer to your specific host or configuration
tool manual for more information.

Reference Manual

00809-0100-4772, Rev FA

2.6 Resource Block

The Resource Block contains diagnostic, hardware and electronics information. There are
no linkable inputs or outputs to the Resource Block.

2.6.1 FEATURES and FEATURES_SEL

The FEATURES parameter is read only and defines which features are supported by the
flowmeter. Below is a list of the FEATURES the flowmeter supports.

FEATURES_SEL is used to turn on any of the supported features that are found in the
FEATURES parameter. The default setting of the flowmeter does not select any of these
features. Choose one or more of the supported features if any.

UNICODE

All configurable string variables in the flow meter, except tag names, are octet strings.
Either ASCII or Unicode may be used. If the configuration device is generating Unicode octet
strings, you must set the Unicode option bit.

REPORTS

The flow meter supports alert reports. The Reports option bit must be set in the features bit
string to use this feature. If it is not set, the host must poll for alerts. If this bit is set, the
transmitter will actively report alerts.

SOFT W LOCK and HARD W LOCK

Inputs to the security and write lock functions include the hardware security switch, the
hardware and software write lock bits of the FEATURE_SEL parameter, the WRITE_LOCK
parameter, and the DEFINE_WRITE_LOCK parameter.

The WRITE_LOCK parameter prevents modification of parameters within the device except
to clear the WRITE_LOCK parameter. During this time, the block will function normally
updating inputs and outputs and executing algorithms. When the WRITE_LOCK condition is
cleared, a WRITE_ALM alert is generated with a priority that corresponds to the WRITE_PRI
parameter.

The FEATURE_SEL parameter enables the user to select a hardware or software write lock or
no write lock capability. To enable the hardware security function, enable the HW_SEL bit in
the FEATURE_SEL parameter. When this bit has been enabled the WRITE_LOCK parameter
becomes read only and will reflect the state of the hardware switch. In order to enable the
software write lock, the SW_SEL bit must be set in the FEATURE_SEL parameter. Once this
bit is set, the WRITE_LOCK parameter may be set to “Locked” or “Not Locked.” Once the
WRITE_LOCK parameter is set to “Locked” by either the software or the hardware lock, all
user requested writes as determined by the DEFINE_WRITE_LOCK parameter shall be
rejected.

Configuration and Operation

March 2016

The DEFINE_WRITE_LOCK parameter allows the user to configure whether the write lock
functions (both software and hardware) will control writing to all blocks, or only to the
resource and transducer blocks. Internally updated data such as process variables and
diagnostics will not be restricted by the security switch.

Table 2 -1displays all possible configurations of the WRITE_LOCK parameter.

no alerts are reported.

2.6.3 PlantWeb™ alarms

The alarms and recommended actions should be used in conjunction with Tabl e 7-2 .

The Resource Block will act as a coordinator for PlantWeb alarms. There will be three alarm
parameters (FAILED_ALARM, MAINT_ALARM, and ADVISE_ALARM) which will contain
information regarding some of the device errors which are detected by the transmitter
software. There will be a RECOMMENDED_ACTION parameter which will be used to display
the recommended action text for the highest priority alarm. FAILED_ALARM will have the
highest priority followed by MAINT_ALARM and ADVISE_ALARM will be the lowest priority.

FAILED_A LARMS

A failure alarm indicates a failure within a device that will make the device or some part of
the device non-operational. This implies that the device is in need of repair and must be
fixed immediately. There are four parameters associated with FAILED_ALARMS specifically,
they are described below.

Reference Manual

FAI LED_EN ABLED

This parameter contains a list of failures in the device which makes the device
non-operational that will cause an alarm to be sent. Below is a list of the failures with the
highest priority first.

1. NV memory failure

2. Sensor board electronics failure

3. Output board electronics failure

4. Thermocouple failure (MTA only)

following standard alarms:

 High (HI_LIM)

 High high (HI_HI_LIM)

 Low (LO_LIM)

 Low low (LO_LO_LIM)

In order to avoid alarm chattering when the variable is oscillating around the alarm limit, an
alarm hysteresis in percent of the PV span can be set using the ALARM_HYS parameter. The
priority of each alarm is set in the following parameters:

 HI_PRI

 HI_HI_PRI

 LO_PRI

 LO_LO_PRI

priority.

2.8.5 Status options

Status options (STATUS_OPTS) supported by the AI block are shown below:

Propagate fault forward

If the status from the sensor is Bad, Device failure or Bad, Sensor failure, propagate it to OUT
without generating an alarm. The use of these sub-status in OUT is determined by this
option. Through this option, the user may determine whether alarming (sending of an alert)
will be done by the block or propagated downstream for alarming.

Configuration and Operation

Uncertain if limited

Set the output status of the Analog Input block to uncertain if the measured or calculated
value is limited.

BAD if limited

Set the output status to Bad if the sensor is violating a high or low limit.

Uncertain if man mode

Set the output status of the Analog Input block to uncertain if the actual mode of the block
is Man.

Note

The instrument must be in Out of Service mode to set the status option.

2.8.6 Advanced features

The AI Function Block provides added capability through the addition of the following
parameters:

ALARM_TYPE

ALARM_TYPE allows one or more of the process alarm conditions detected by the AI
function block to be used in setting its OUT_D parameter.

OUT_D

Reference Manual

00809-0100-4772, Rev FA

OUT_D is the discrete output of the AI function block based on the detection of process
alarm condition(s). This parameter may be linked to other function blocks that require a
discrete input based on the detected alarm condition.

2.9 Flow simulation

The electronics is capable of internally generating a flow signal that may be used to simulate
a sensor signal. The simulated signal amplitude is based on the transmitter required
minimum process density. The simulated signal can be a constant frequency or the
simulated signal can be a varying frequency to represent a ramping flow rate.

Simulating the flow signal requires the simulate ENABLE jumper on the transmitter
electronics board to be in the ‘ON’ position. The transmitters are shipped with the jumper
in the ‘OFF’ position.

2.9.1 Using transducer block parameters

SIMULATION_CONTROL

Sim Disabled—Normal operation, no simulated flow signal.

Sim—Internal Generator—The internal frequency generator will produce the frequency
signal.

‘Simulate Flow’ button. Follow the steps for the desired flow simulation.

2.10 Device capabilities

2.10.1 Link active scheduler

The flowmeter can be designated to act as the Backup Link Active Scheduler (BLAS) in the
event that the LAS is disconnected from the segm ent. As the backup LAS, the flowmeter will
take over the management of communications until the host is restored.

The host system may provide a configuration tool specifically designed to designate a
particular device as a backup LAS. Otherwise, this can be configured manually as follows:

1. Access the Management Information Bose (MIB) for the flowmeter.

2. To activate the LAS capability, write 0x02 to the
BOOT_OPERAT_FUNCTIONAL_CLASS object (Index 605). To deactivate, write
0x01.
