1.0 FOUNDATION fieldbus

™

Overview

1.1 Description

UNDATION

fieldbus

™

is a digital communications system

that serially interconnects devices in the field. A Fieldbus

system is similar to a Distributed Control System (DCS)

with two exceptions:

• Although a F

OUNDATION fieldbus

™

system can use the same

physical wiring as an existing 4–20 mA device, Fieldbus

devices are not connected point to point, but rather are

multidropped and wired in parallel on a single pair of wires

(referred to as a segment).

•F

OUNDATION fieldbus

™

is a system that allows the user to

distribute control across a network. Fieldbus devices are

smart and actually maintain control over the system.

Unlike 4–20 mA analog installations in which the two wires

carry a single variable (the varying 4–20 mA current), a dig-

ital communications scheme such as F

OUNDATION fieldbus

™

considers the two wires as a network. The network can carry

many process variables as well as other information. The

E3 Modulevel

transmitter is a FOUNDATION fieldbus

™

reg-

istered device that communicates with the H1

OUNDATION fieldbus

™

protocol operating at 31.25

kbits/sec. The H1 physical layer is an approved IEC 61158

standard.

An IEC61158 shielded twisted

pair wire segment can be as long

as 6234 feet (1900 meters) with-

out a repeater. Up to 4 repeaters

per segment can be used to extend

the distance. The maximum num-

ber of devices allowed on a

Fieldbus segment is 32 although

this depends on the current draw

of the devices on any given seg-

ment. See Figure 1.

Details regarding cable specifica-

tions, grounding, termination, and

other network information can be

found in IEC 61158 or the wiring

installation application guide

48-640 E3 Modulevel

Displacer Level Transmitter - FOUNDATION fieldbus

™

1.2 Benefits

The benefits of F

OUNDATION fieldbus

™

can be found

throughout all phases of an installation:

1. Design/Installation: Connecting multiple devices to a single

pair of wires means less wire and fewer I/O equipment.

Initial Engineering costs are also reduced because the

Fieldbus Foundation requires interoperability, defined as

“the ability to operate multiple devices in the same system,

regardless of manufacturer, without a loss of functionality.”

All F

OUNDATION fieldbus

™

devices must be tested for

interoperability by the Fieldbus Foundation. Magnetrol

E3 MODULEVEL FOUNDATION fieldbus

™

device registration

information can be found at www.fieldbus.org.

2. Operation: With control now taking place within the

devices in the field, better loop performance and control are

the result. A FOUNDATION fieldbus

™

system allows for mul-

tiple variables to be brought back from each device to the

control room for additional trending and reporting.

3. Maintenance: The self-diagnostics residing in the smart

field devices minimizes the need to send maintenance

personnel to the field.

1.3 Device Configuration

Device Descriptions

The function of a FOUNDATION fieldbus

™

device is deter-

mined by the arrangement of a system of blocks defined by

the Fieldbus Foundation. The types of blocks used in a typi-

cal User Application are described as follows:

Resource Block describes the characteristics of the

OUNDATION fieldbus

™

device such as the device name,

manufacturer, and serial number.

Function Blocks are built into the F

OUNDATION fieldbus

™

devices as needed to provide the desired control system

behavior. The input and output parameters of function

blocks can be linked over the Fieldbus. There can be

numerous function blocks in a single User Application.

Transducer Blocks contain information such as calibration

parameters and sensor type. They are used to connect the

sensor to the input function blocks.

An important requirement of Fieldbus devices is the inter-

operability concept mentioned earlier. Device Description

(DD) technology is used to achieve this interoperability.

The DD provides extended descriptions for each object and

provides pertinent information needed by the host system.

48-640 E3 Modulevel

Displacer Level Transmitter - FOUNDATION fieldbus

™

DDs are similar to the drivers that your personal computer

(PC) uses to operate peripheral devices connected to it. Any

Fieldbus host system can operate with a device if it has the

proper DD and Common File Format (CFF) for that device.

The most recent DD and CFF files can be found on the

OUNDATION fieldbus

™

web site at fieldbus.org.

1.4 Intrinsic Safety

The H1 physical layer supports Intrinsic Safety (IS) applica-

tions with bus-powered devices. To accomplish this, an IS

barrier or galvanic isolator is placed between the power

supply in the safe area and the device in the hazardous area.

H1 also supports the Fieldbus Intrinsically Safe Concept

(FISCO) model which allows more field devices in a

network. The FISCO model considers the capacitance and

inductance of the wiring to be distributed along its entire

length. Therefore, the stored energy during a fault will be

less and more devices are permitted on a pair of wires.

Instead of the conservative entity model, which only allows

about 90 mA of current, the FISCO model allows a maxi-

mum of 110 mA for Class II C installations and 240 mA

for Class II B installations.

FISCO certifying agencies have limited the maximum

segment length to 1000 meters because the FISCO model

does not rely on standardized ignition curves.

The E3 MODULEVEL is available with entity IS, FISCO IS,

FNICO non-incendive, or explosion proof approvals.

1.5 Link Active Scheduler (LAS)

The default operating class of the E3 MODULEVEL with

OUNDATION fieldbus

™

is a basic device. However, it is

capable of being a Link Active Scheduler (LAS). The LAS

controls all communication on a F

OUNDATION fieldbus

™

segment. It maintains the “Live List” of all devices on a seg-

ment, coordinates both the cyclic and acyclic timing and, at

any given time, controls which device publishes data via

Compel Data (CD) and Pass Token (PT).

The primary LAS is usually maintained in the host system,

but in the event of a failure, all associated control can be

transferred to a backup LAS in a field device such as

the E3 MODULEVEL. The operating class of

E3 MODULEVEL can be changed from basic to LAS

using a F

OUNDATION fieldbus configuration tool.

3.1 Unpacking

Unpack the instrument carefully. Take care not to bend the

displacer stem or enclosing tube. Ensure all components

have been removed from the packing material. Check all the

contents against the packing slip and report any discrepan-

cies to the factory.

Before proceeding with the installation, do the following:

• Inspect all components for damage. Report any damage to

the carrier within 24 hours.

• On chambered units, remove the shipping strap and wire

assembly holding the displacer in place. This assembly must

be removed through the bottom chamber connection before

start-up.

 If reshipping to another location, the displacer must again

be secured using the same strap and wire assembly.

• Check that the model number on the nameplate matches

the packing slip and purchase order.

• Record the model and serial numbers for future reference

when ordering parts.

3.2 Electrostatic Discharge (ESD)

Handling Procedure

MAGNETROL electronic instruments are manufactured

to the highest quality standards. These instruments use

electronic components which may be damaged by static

electricity present in most work environments.

The following steps are recommended to reduce the risk of

component failure due to electrostatic discharge.

• Ship and store circuit boards in anti-static bags. If an anti-

static bag is not available, wrap the board in aluminum foil.

Do not place boards on foam packing materials.

• Use a grounding wrist strap when installing and removing

circuit boards. A grounded workstation is recommended.

• Handle circuit boards only by the edges. Do not touch

components or connector pins.

• Ensure that all electrical connections are completely made

and that none are partial or floating. Ground all equipment

to a good, earth ground.

Each E3 MODULEVEL transmitter is built to match the

physical specifications of the required installation. Ensure

that the process connection(s) on the vessel matches the

MODULEVEL process connection(s).

See Mounting, Section 3.4.

Ensure that the wiring between the power supply and

MODULEVEL transmitter are complete and correct for the

type of installation.

When installing the MODULEVEL transmitter in a general

purpose or hazardous area, local, state and federal regulations

and guidelines must be observed.

See Wiring, Section 3.5.3.

The MODULEVEL transmitter should be located for easy

access for service, configuration, and monitoring. There

should be sufficient headroom to allow installation and

removal of the transmitter head and, in cases of tank top

configuration, the displacer. Special precautions should be

made to prevent exposure to corrosive atmosphere, excessive

vibration, shock, or physical damage.

The operating temperature range for the transmitter elec-

tronics is -40 to +176 °F (-40 to +80 °C). The operating

temperature range for the digital display is -5 to +160 °F

(-20 to +70 °C).

 Operation of all buoyancy type level devices should be

done in such a way as to minimize the action of dynamic

forces on the float or displacer sensing element. Good

practice for reducing the likelihood of damage to the con-

trol is to equalize pressure across the device very slowly.

48-640 E3 Modulevel

Displacer Level Transmitter - FOUNDATION fieldbus

3.4 Mounting

The E3 MODULEVEL transmitter can be mounted to a

tank using a variety of configurations and process connec-

tions. Generally, either a threaded, welded or flanged con-

nection is used with an external cage. A flanged connection

is always used on a tank top model. For information

about the sizes and types of connections available, see

Model Numbers, Section 8.7.

Ensure all mounting connections are in place on the tank

and properly sized for the specific unit being installed.

Compare the model on the nameplate with the product

information to ensure the MODULEVEL transmitter is

correct for the intended installation.

If the MODULEVEL must be insulated, DO NOT insulate

the transmitter head, e-tube or finned extensions.

Figure 6 illustrates a typical tank top installation.

Before installing, ensure that:

• There is adequate headroom for the installation of the

MODULEVEL head and displacer and that it has unob-

structed entry into the vessel.

• Using a level, the mounting flange is level within 3° in all

directions.

• If the adjustable hanger assembly (P/N 32-3110-001) is

used, it is cut to the required length and attached to the

displacer stem.

NOTE: The adjustable hanger assembly is used when the top of the

displacer and, therefore, the top of the measurement range

must be positioned in the vessel more than 9.31" below the

mounting flange. The standard hanger cable length is 8 feet.

Consult factory for longer cable.

To install:

1. Align the MODULEVEL process connections with

those on the vessel and attach accordingly, based upon the

connection type. Appropriate gaskets and bolting will be

required for flanged connections. Install the flange bolts and

nuts and tighten alternating nuts in a star pattern. Flange

bolting torque specifications are listed on page 12.

NOTE: It is recommended that shut-off valves be installed in each

equalizing line to the chamber, along with a drain valve (refer to

Figure 8). Equalizing lines should be sized at least as large as

the connections provided at the chamber.

2. Make sure that the chamber is vertically level within 3° in

each direction to ensure frictionless operation of the internal

displacer.

Explosion Proof (XP) is a method of designing equipment

for installation in hazardous areas. A hazardous location is

an area in which flammable gases or vapors are, or may be,

present in the air in quantities sufficient to produce explo-

sive or ignitable mixtures. The wiring for the transmitter

must be contained in Explosion Proof conduit extending

into the safe area.

To install Explosion Proof wiring – Integral mount:

Due to the specialized design of the Integral E3 transmitter,

no Explosion Proof conduit fitting (EY seal) is required

within 18" of the transmitter. An Explosion Proof conduit

fitting (EY seal) is required between the hazardous and safe

areas. See Agency Approvals, Section 8.4.

1. Install Explosion Proof conduit from the safe area to the

conduit connection of the E3 transmitter (refer to local

plant or facility procedures).

2. Remove the cover to the wiring compartment of the

transmitter.

3. Connect shield to an earth ground at the power supply.

4. Connect an Earth ground wire to the nearest green ground

screw per local electrical code. Use a minimum 18 AWG

rated up to 85 °C.

5. Connect the positive supply wire to the (+) terminal and the

negative supply wire to the (-) terminal.

6. Replace the cover to the wiring compartment of the

4.0 Function Blocks

4.1 Overview

The E3 MODULEVEL Liquid Level Displacer Transmitter

operates on the Archemedes principle of buoyancy force.

Refer to Bulletin 48-635 for more detailed information on

the MODULEVEL transmitter.

The E3 MODULEVEL is a liquid level transmitter with

four F

UNDATION

fieldbus

™

Blocks (one Resource Block,

one Transducer Block, one Analog Input Function block,

and one PID Function block. The idea of Function Blocks,

which a user can customize for a particular application, is a

key concept of Fieldbus topology. Function Blocks consist

of an algorithm, inputs and outputs, and a user-defined

name.

The TRANSDUCER block output is available to the

network through the ANALOG INPUT block.

• The ANALOG INPUT block (AI) takes the TRANSDUCER

block level or density value and makes it available as an

analog value to other function blocks. The AI block has

scaling conversion, filtering, and alarm functions.

The following are general descriptions of the parameters

common to all blocks. Additional information for a given

parameter is described later in that specific block section.

ST_REV (static data revision): a read only parameter that

gives the revision level of the static data associated with the

block. This parameter will be incremented each time a static

parameter attribute value is written and is a vehicle for

tracking changes in static parameter attributes.

TAG_DESC (tag descriptor): a user assigned parameter

that describes the intended application of any given block.

STRATEGY: a user assigned parameter that identifies

groupings of blocks associated with a given network connec-

tion or control scheme.

ALERT_KEY: a user assigned parameter which may be used

in sorting alarms or events generated by a block.

MODE_BLK: a structured parameter composed of the

actual mode, the target mode, the permitted mode(s), and

the normal mode of operation of a block.

• The actual mode is set by the block during its execution to

reflect the mode used during execution.

• The target mode may be set and monitored through the

mode parameter.

48-640 E3 Modulevel

Displacer Level Transmitter - FOUNDATION fieldbus

™

• The permitted modes are listed for each block.

• The block must be in an automatic mode for normal

operation.

NOTE: The MODE_BLK target parameter must be OOS (out of service)

to change configuration and calibration parameters in that func-

ion block (when in OOS, the normal algorithm is no longer exe-

cuted and any outstanding alarms are cleared).

All blocks must be in an operating mode for the device to oper-

ate. This requires the Resource Block to be in “AUTO” and the

Transducer Block to be in “AUTO” before the Function Blocks

can be placed in a mode other than OOS (out of service).

BLOCK_ERR: a parameter that reflects the error status of

hardware or software components associated with, and

directly affecting, the correct operation of a block.

NOTE: A BLOCK_ERR of “Simulation” in the Resource Block does not

mean simulation is active—it merely indicates that the simula-

tion enabling hardware jumper is installed.

4.2 Resource Block

The RESOURCE block contains data specific to the

E3 MODULEVEL transmitter, along with some

information about the firmware.

NOTE: The Resource Block has no control function.

MODE_BLK: Must be in AUTO in order for the remain-

ing blocks in the transmitter to operate.

NOTE: A Resource Block in “out of service” will stop all function block

execution in the transmitter.

RS_STATE (Resource State): identifies the state of the

RESOURCE block state machine. Under normal operating

conditions, it should be “On-Line.”

DD_RESOURCE: a string identifying the tag of the

resource that contains the Device Description for this device.

MANUFAC_ID: contains the MAGNETROL International,

Incorporated F

OUNDATION fieldbus

™

manufacturer’s ID

number, which is 0x000156.

DEV_TYPE: the model number of the E3 MODULEVEL

transmitter (0x0003). It is used by interface devices to

locate the Device Descriptor (DD) file for this product.

DEV_REV: contains the firmware revision of the

E3 MODULEVEL transmitter. It is used by interface

devices to correctly select the associated DD.

48-640 E3 Modulevel

Displacer Level Transmitter - FOUNDATION fieldbus

™

DD_REV: contains the revision of the DD associated with

the version of firmware in the E3 MODULEVEL transmitter.

It is used by interface devices to correctly select the associat-

ed DD.

RESTART: Default and Processor selections are available.

Default will reset the Model E3 to the default block

configuration.

NOTE: RESTART DEFAULT will not reset parameters to their default

values in the custom Transducer Block.

FEATURES: a list of the features available in the transmit-

ter. The Model E3 features include Reports, and Software

Write Locking.

FEATURES_SEL: allows the user to turn Features on or off.

CYCLE_TYPE: identifies the block execution methods that

are available.

CYCLE_SEL: allows the user to select the block execution

method.

MIN_CYCLE_T: the time duration of the shortest cycle

interval. It puts a lower limit on the scheduling of the

resource.

NV_CYCLE_T: the minimum time interval between copies

of non-volatile (NV) parameters to NV memory. NV mem-

ory is only updated if there has been a significant change in

the dynamic value and the last value saved will be available

for the restart procedure. A value of “0” means it will never

be automatically copied. Entries made by human interface

devices to NV parameters are copied to non-volatile memory

at the time of entry.

NOTE: After completing a large copy, allow several minutes before

removing power from the E3 MODULEVEL transmitter to ensure

that all data has been saved.

FREE_SPACE: shows the amount of available memory for

further configuration. The value is zero percent in a pre-

configured device.

FREE_TIME: the amount of the block processing time that

is free to process additional blocks.

SHED_RCAS: the time duration at which to give up com-

puter writes to function block RCas locations. Shed from

RCas will never happen when SHED_RCAS = 0.

SHED_ROUT: the time duration at which to give up com-

puter writes to function block ROut locations. Shed from

ROut will never happen when SHED_ROUT = 0.

48-640 E3 Modulevel

Displacer Level Transmitter - FOUNDATION fieldbus

™

FAULT_STATE, SET_FSTATE, CLR_FSTATE: these only

apply to output function blocks. (The E3 MODULEVEL

has no output function blocks).

MAX_NOTIFY: the maximum number of alert reports that

the transmitter can send without getting a confirmation.

The user can set the number low, to control alert flooding,

by adjusting the LIM_NOTIFY parameter value.

LIM_NOTIFY: the maximum numbers of unconfirmed

alert notify messages allowed. No alerts are reported if set

to zero.

CONFIRM_TIME: the time that the transmitter will wait

for confirmation of receipt of a report before trying again.

Retry will not occur if CONFIRM_TIME = 0.

WRITE_LOCK: When set to LOCKED, will prevent any

external change to the static or non-volatile data base in the

Function Block Application of the transmitter. Block con-

nections and calculation results will proceed normally, but

the configuration will be locked.

UPDATE_EVT (Update Event): is an alert generated by a

write to the static data in the block.

BLOCK_ALM (Block Alarm): is used for configuration,

hardware, connection, or system problems in the block. The

cause of any specific alert is entered in the subcode field.

The first alert to become active will set the Active status in

the Status attribute. As soon as the Unreported status is

cleared by the alert reporting task, another block alert may

be reported without clearing the Active status, if the sub-

code has changed.

ALARM_SUM (Alarm Summary): contains the current

alert status, the unacknowledged states, the unreported

states, and the disabled states of the alarms associated with

the block.

ACK_OPTION (Acknowledge Option): selects whether

alarms associated with the block will be automatically

acknowledged.

WRITE_PRI (Write Priority): the priority of the alarm

generated by clearing the write lock.

WRITE ALM (Write Alarm): the alert generated if the

write lock parameter is cleared.

ITK_VER (ITK Version): contains the version of the

Interoperability Test Kit (ITK) used by the Fieldbus

Foundation during their interoperability testing.
