Grounding the FIM

Wiring the FIM

1. Insert one U-bolt around the pipe and through the top mounting holes
of the pipe mount and the FIM and another U-bolt through the bottom
mounting holes of the pipe mount and the FIM.

2. Using a

/2 inch socket-head wrench, fasten nuts to the U-bolts.

If mounting the Ros emount 3420 i n the fi eld, ground the FI M w i th a
connection of 1 Ω or less leading from the external grounding lug to earth
ground. If mounting the FIM in the control room, a cabinet ground is sufficient.
In either location, follow local or plant electrical codes.

FIM wiring is done in the terminal block. For access to the terminal block,
open the junction box cover following the i ns tru ction “I n sta llation P rocedure”
on page 2-3. The terminal block label is located on the inside of the FI M
junction box cover.

At the bottom of the junction box in

/2 inch NPT conduit entries are four plastic
plugs that were placed there at th e factory. Four metal plugs were shipped
with the FIM and are used to seal any unused ports.

The FIM case should always be grounded in accordance with national and
local electrical codes. The most effective grounding method is direct
connection to eart h ground w i th mini mal impedance.

suitable for 185°F with sufficient capacity to power both the FIM and all of the
fieldbus devices that are connected to it. The Rosemount 3420 requires 500
mA. About 300 mA of additi onal current should be allocated for each H1
segment if the unit is configured with internal power conditioners. The positive
and negative power terminals are found on the left side of the terminal block.
A case ground is also found on the left hand side of the compartment.

Ethernet

The 3420 is equipped with one or two 10/100 Base-T Ethernet interface
receptacles on the left side of the terminal block. Connect the FIM to the PC
that will be used for configuration, using the crossover cable provided with the

Modbus Termination
Setup

Figure 2-2. Modbus Setup

NOTE:

Do not open the 3420 electronics hous ing i n an explosive atmosphere.

Modbus RTU is trans mit ted on an RS485 physical layer. Three dip-swi tche s
are provided to enable the RS485 circuitry with a network terminator. The
swi t ches are found i ns ide th e electroni cs hous ing on the RS485
communication board located in the top center of the housing. Switch 2
places a 120 ohm terminator on the bus. This would be used to match cable
impedance if needed to dampen reflections on long cable runs. Its use w i ll
depend on the baud rate and cable length of the Modbus network.

Swi tche s 1 and 3 are connected t o pull-up and pull-down resisters on the
Modbus network. These resisters are used to prevent noise from being
interpreted as valid communications during periods when no communications
are occurring on the network. Only one set is required on an RS485 network.

The Rosemount 848T temperature transmitter provides 8 AI blocks and 1 MAI
block. An MAI block processes all eight inputs at once. The speed at w hich
the Rosemount 3420 scans all of the measurements from the devi ces on the
fieldbus segments is dependent on the number of AI, MAI, and other function
blocks being polled. For example if 13 Rosemount 848T's were polled with
MAI blocks the scan time would be approximately 1 second for all 104 values.
If the same 13 devi ces w ere polled wi th the AI blocks the scan ti me would be
about 9 seconds (See Table 3-4 on page 3-12).

Modbus Register Rules

Reference Manual

March 2006

Rosemount 3420

The small ex ample file above i s compliant wi th s ome rules that y ou must
follow when changing the mappin gs. These rules are:

• When the Function B lock Output data i s i n floating p oint format it

requires two registers. Therefore nothing may be mapped into the next
regist er speci fi ed for a floating poin t measurement v alue.

• Status information use s one regi s t er and can be located in adjacent

regist ers of the s tatu s i nformati on of other tags.

• Contiguous registers must all be of the same type.

• Do not use regis t ers 4900 1 through 49011

(see Predefi ne d Di agnos t ic Regi s te rs on page 3-19 ).

Modb us Reg ister Gui del in es

The Modbus prot ocol allows for reading contig uous regi s ters of the same
dataty pe i n one read reques t from the Modbu s Master (up to 127 regis t ers
can be communicated i n one read reques t ). To take advantage of efficiently
reading registers, the following guidelines are suggested:

• Fieldbus out put STATUS tags should be mapped to registers i n one

contiguous block starting at register 40001. Each tag requires one
register.

• Fieldbus out put VALUE tags should be mapped to regis ters i n one

contiguous block starting at register 45001. Each tag requires two
regist ers. So me Modbus hos ts use s pecifi c regi s ter numbers for
different types of data. Use the register numbers suggested by your
Modbus hos t.

• Fieldbus COIL tags should be mapped to regist ers i n one cont iguou s

block starting at register 19001. Each tag requires one register.

Snapshot File Format

The file is in Comma Separated Value (CSV) or XM L format as follows:

• The file consists of a series of lines that contain two fields: the label for
the value and the value itself.

• The first record whi ch contai ns the data t i mestamp is opt i onal. If
enabled, it is always the first value reported. Time values are reported
in GMT time.

• Function blocks may be selected from the list, but are not limited to that
list.

• The label for each value is the fully qualified name of the value. Th is is :

<block tag>. <parameter name>.<subparameter name>
Ex a mple: TT-800-1.OUT.STATUS

• The label is user definable.

• The value is a textual representat i on of the poin t bei ng collected. If the
point cannot be collected (the device is offline, etc.), a value of the
form: “error: <descriptive message>” is written.

The following is an example of the records for reading information:

OVERVIEW

On power up, the FIM will determine what devices are attached to each of the
fieldbus segments. If Plug and Play has been selected i n th e Setup, each
devi ce w i ll be interrogated and any unscheduled function blocks will be
init i alized as speci fi ed on t he
page. The first time the unit is powered up it is recommended that no devices
be connected so that t he Plug and Play s etti n gs can be configured. The FI M
will poll and update the values at a frequency depending on the number of
function blocks bein g polled on each segment according to Table 3-4 on
page 3-12.

INTEGER SCALING

CONFIGURING SCALED
INTEGERS

If you read process v ariables from integer registers , the 3420 ordi n ari ly
returns a rounded int ege r, such as 2712 to represent 2711.97 grams per
minute, or 1 to indicate a density of 1.2534 grams per cubic centimeter.

Intege r scaling causes the 3420 to return i ntegers , accurate to one part i n
65536, represent i ng the measured v alue of the process v ariab le, such as
50000 to represent a mass flow rate of 50 grams per second. Scaled integers
amplify and linearize s mall changes in critical process v a ri ables.

You can implement integer scaling for the followin g purpos es :

• To of fset negative values such as subzero temperatures or reverse flow
rates, so they can be read as positive in tege rs.

• To increas e output reso luti on of va lues such as density, temperature,
pressure, or low flow rates .

If you configure i nt eger s caling for more than one process vari ab le, the same
maxi mum integer applies to all scaled process v ari ables. E ach scaled
process variable can have its own offset and scale factor.

To determine a scaled int eger proport i onal to the measured v a lue of a
process variable, the 3420 uses a variation of the linear equation. The
equation represents a linea r correction of the measured v alue:

y = Ax - (B - 32768)

Where:

y = Scaled int eger retu rned by the3420

www.rosemount.com

A = Gain for scaled int eger va lues
x = Measured value of the process variable
B = Offset for scaled integer values

To configure integer scaling of process variables, follow these steps:

1. Select a maxi mum integer and wri t e i ts v alue in t he appropri at efi eld

page. If you are usi ng

Step 1: Determine
Maximum Integer

A scaled intege r is the v alue of y i n th e equat i on pres ent ed above. The
maximum integer is the highest integer proportional to a measured value of a
process variable. The default maximum integer is 65534.

KEY TO USING MA XIMUM INTEGERS

If inte ger scali ng applies to more than one process v ari able, all scales must
share the same maximum integer, but may have different offsets and scale
factors.

You can program a m axim um integer below the default m aximum integer. The
maximum integer selected may be determined by the Modbus host’s
capabiliti es . F or ex a mple, the Honey w ell control sys t em allows transmis sion
of integer v alues from 0 to 9999 or from 0 to 4096.

The overflow integer is defined as the maximum integer plus 1. Therefore, if
the maxi mum integer is 1000, the overflow integer i s 1001. If the default
maxi mum integer is used (65534), th e default ov erflow i nt eger i s 65535.

The 3420 returns the overflow integer if the measured value of a process
vari able deri v e s an int eger hi ghe r than the max i mum integer. The transmitter
also returns the overflow integer if any of the following alarm conditions exists:

• Sensor failure

• Input overrange

• Density outside sensor limits

• Temperature outside sensor limits

• Transmitter electronics failure

Step 2: Determine the
Gain (Slope)

Step 3: Determine Offset

E-2

The scale factor is the v alue of A in the equa tio n above. The scale factor
equals the linear slope of the int egers, which are proportional to measured
values of the process variable. The scale factor therefore is a rati o th at
compares the change in the measured value to th e proporti o nal change in
value of the scaled int egers .

The offset for scaled integers is the value of B in the equatio n above. The
intercept, or the offset minus 327 68, equa ls the v alue of the process variable
that is represented by a scaled integer value of 0. The offset enables scaled
integers , w hich always have posit i v e v a lues, t o represe nt negat i ve values
such as a subzero temperature or a rev erse flow rate.

Since B (the offset) alway s has a v alue from 0 to 65534, the3420 uses the
following equati on to derive a posi ti ve or negativ e i nt ercept :

Reference Manual

Rosemount 3420

Intercept = Offset - 32768

• The maximum negative intercept is -32768, where the offset = 0.

• The intercept is 0, where the offset = 32768

• The maximum positi ve intercept is 32767 , w here the offset = 65535

So, although y ou w ri t e the offset as an int eger from 0 to 65535, the process
vari able can hav e a v alue less than, equal to, or greater th an 0.

Exampl e 1

The 3420 FIM is connected to a Honeywell TDC3000 control system using a
PLC Gateway. The control system engineer sets up an analog input point to
bring in volume flow, which enables use of flow limit alarms in the control
sys t em. On the control system, an analog input poi nt has limits of 0 to 4095,
with any input greater than 4095 indicating a “bad” process variable. The
lower range limit is -100 barrels/day. The upper range limit is 300 barrels/ day.

1. Set up the maximum integer, if necessary.

2. Set up scaled int eger limits correspon di ng to the lower and upper

range values.

Detailed status information can be called up from AMS Alert Monitor

In order for devi ce alerts to be reported to t he Alert Mon i to r from the 3420,
some setup is required. The following is a list of setup requirements to ensure
correct operation of Alert M onitor:

1. When performing the Network Configurat i on for AM S Device
Manager, check the “

Fieldbu s Alerts

described above.

2. Some devices allow specific device alerts to be enable or disabled. In
these cases, make sure the alerts are enabled. These settings are
typically in the device’s Transducer Block and can be changed via
AMS Device Mana ger.

3. Some devices allow a device alert to be suppressed. This is different
than dis ablin g the alert. M a ke sure the alert is not su ppres s ed. Thi s
setti ng i t ty pi cally in the device’s Resource Block.

4. For a devi ce to have its alerts show up i n A lert M oni tor, it must be in
the AMS Device Manager Plant Database. Make sure the fieldbus
device connected to the 3420 has been placed in the Plant Database.
This is done be “draggi n g” the dev i ce sho w n under the 3420 to a
folder in the Plant Database.

5. For a device to show up in Alert Monitor, it must be include in the Alert
Monitor List. This is done using the following steps:

a.) Select
b.) Select
c.) Select the device(s) to be added and select
d.) Select OK again

6. For an alert to show up in Alert Monitor, it is necessary that the
Devi ce Des cri pti on for that device be av ai lable in the 3420. The
method for doing this i s des cri bed unde r the “Advanced” subsect i on
in the Section labeled Fieldbus Field Devices earlier in this manual.
Usually thi s i s not ne cessary unless the dev i ce involved i s not a
commonly used fi eldbus device.

7. For a devi ce to s how up i n the A lert M onit or, it is neces s ary that the
“Reports” option be enabled. For Rosemount devices, this field is
found under the “Option s” tab i n th e Resou rce Block.

8. Finally, it is necess ary that a device connected to the 3420 change
from the normal to alert state for it to show up i n the Alert M onitor. If
the device is already in the alert state when the device is added to the
Alert Monitor List, it will not show up until it transitions into the alert

A device attached to the end of a communications bus or network to
absorb signals so they do not reflect back.

The resource block defines device specific characteristics such as
software revisions, hardware revision and materials of const ruction.

The transducer block defines device specific input/output
characteristics for function block application purposes. It contains
universal parameters and device specific parameters such as trim
limits, sensor type , se nso r se rial numbe r a n d se nso r dia g nostic
information.

Function blocks define the capabilities of the high level measurement
and control available in the device. There are many possible function
block capabilities contained in a device such as analog input, discrete
input, discrete output, signal characterizer , arithmetic, integrator, PD or
PID control, input select or or analog output.

Scanned by the Rosemount 3420.

Provides up to 8 variable in one function block, reducing scan times.

- The mode requested by the operator

Actual

- The current mode of the block which may differ from the
target based on the current operating conditions. The actual mode is
calculated during block execution.

Permitted
Normal

- The desired operating mode of the block.

In t his m o d e t h e algo rithm of t h e b lock is no l o n ger bei n g execu ted and
any outstanding alarms will be cleared. This is the high est priority
mode.

In thi s m ode the bloc k algorit hm i s b eing executed wi t h new value and
status as well as mode being computed each Macrocycle or execution
of the block

In this mode the block output is not being calculated although it may
be limited. It is set directly by the operator through an interface device.

The period of execution in which the function block schedule is
defined.

The rate and relative time which function blocks process their inputs
and generate their outputs. The schedule defines when a function
block is triggered to start execution

A link master device is a device that is capable of becoming the LAS.
There is a bid procedure that is followed that selects the link master
device with the lowest node address.

The LAS performs five functions:

• Maintains the schedule to send compel data (CD) messages
(DLPDU's) to devices on the network. This is the highest priority
function.

• Sends probe node (PN) messages to unused addresses to detect
new devices added to the link/segment and adds them to t he Live
List when found.

• Periodically distributes data link time and link schedule time

• Send pass token (PT) messages to devices to provide them the
opportunity to send unscheduled data.

• Monitor responses to pass token (PT) messages and removes
devices from the Live List when a device fails to use or return the
token.

The 32 character name of the device.
The 32 character name of the function block.
The name of the function block parameter.
The name of the function block sub parameter.
