Human-Machine Interface (HMI) Module

The flow computer includes an HMI module with an optional liquid crystal display (LCD) for local operator access to the device. The LCD, if present, shows a series of menus that sequentially display the current values of particular process variables. A configuration parameter in FBxConnect determines whether you must log in first to view the menus. If required, you log in by selecting alphanumeric characters by scrolling through a list until you select the correct character.

The HMI module includes four LEDs to provide status information. Units with the display include four infrared (IR) buttons for operator interaction.

To conserve power the HMI module enters sleep mode after a period of inactivity. Sleep mode disables FBxWifi communication. In FBxConnect, you can configure the number of minutes of inactivity triggering sleep mode through the LCD Sleep Time parameter. Setting this parameter to

0 disables sleep mode which keeps the HMI module on but uses significantly more power.

Note

If your flow computer does not include the LCD option (shown in Figure 1-4 ), you still have the status LEDs and a single IR button for waking up the device (shown in Figure 1-5 ).

FBxWifi Communications

The flow computer has an optional Wi-Fi ® transceiver (FBxWifi) that enables you to connect via a laptop or tablet from some small distance away. The distance supported varies depending on the laptop/tablet type and environmental conditions, but is typically 70 to 100 feet from the front and

40 to 60 feet from the side and rear.

This capability allows an operator to potentially remain outside the hazardous location and still communicate with the flow computer. The operator's laptop must have Wi-Fi capability, line-ofsight access to the HMI module, and must be loaded with FBxConnect configuration software.

Once connected, the operator can view process values, edit configuration parameters, and collect logs.

Note

The FBxWifi electronics reside inside the HMI module. The HMI module must be awake to use

FBxWifi communications You can wake it up manually by holding a finger against the front cover glass over the Hold to Wake button (the left-most button) for typically from five to ten seconds.

General Wiring Guidelines

The flow computer’s pluggable terminal blocks use compression-type terminals that accommodate wire between 28 and 12 AWG.

When making a connection, insert the bare end of the wire (approx. 1/4" max) into the clamp adjacent to the screw and secure the screw.

To prevent shorts, ensure that no bare wire is exposed.

Allow some slack in the wire while making terminal connections. Slack makes the wires more manageable and helps minimize mechanical strain on the terminal blocks.

Use twisted pair, shielded and insulated cable for communication and I/O wiring to minimize signal errors caused by electromagnetic interference (EMI), radio frequency interference

(RFI) and transients. When using shielded cable, ground all shields at only one point in the appropriate system. This prevents circulating ground current loops that can cause signal errors.

Grounding

The flow computer includes a ground stud on the bottom of the battery compartment

Installation

Emerson FB2100 Flow Computer Instruction Manual

D301783X012

August 2020

Figure 2-7. Ground Stud

2.7



Once you have installed the unit, run a ground wire between the ground stud on the bottom of the battery compartment and a known good earth ground. You route the ground wire through one of the conduit fittings.

Use stranded copper wire to earth ground and keep the length as short as possible.

Clamp or braze the ground wire to the ground bed conductor (typically a stranded copper AWG 0000 cable installed vertically or horizontally).

 Run the ground wire so that any routing bend in the cable has a minimum radius of

30.48 cm (12 inches) below ground and 20.32 cm (8 inches) above ground.

For more information on grounding or if your installation uses cathodic protection, refer to Site

Considerations for Equipment Installation, Grounding, and Wiring (D301452X012) .

Opening/Closing the Enclosure

The enclosure opens/closes differently depending upon whether you have the fiberglass enclosure or the aluminum enclosure.

DANGER

EXPLOSION HAZARD: Never open the enclosure in a hazardous location. Opening the enclosure in a hazardous location could result in an explosion.

Fiberglass Enclosure

The enclosure includes two fasteners at the top and bottom of the door. To open the door, lift the clasp to loosen the latch and pull it free of the post, then repeat for the other fastener and open the door. To fasten the door, place the latch on the post and press down the clasp; repeat for the other fastener.

Installation 19

Emerson FB2100 Flow Computer Instruction Manual

August 2020

Figure 2-8. Fiberglass Enclosure Fasteners

 Aluminum Enclosure

The enclosure includes six clamps along the edge of the door (two at the top, two on the bottom, two at the side). To open the door, use a Phillips-head screwdriver to loosen (but not remove) the screws enough so you can then pop the clamp free of the lip of the door, then repeat for the other clamps and open the door. To fasten the door, place the clamp over the door lip then tighten the screw torqueing to 20 in-lbs (2.3 N m); repeat for the other clamps.

Figure 2-9. Aluminum Enclosure Clamps

2.8 Mounting the Enclosure

You can mount the flow computer directly to a pole. You can also mount it on a wall or panel.

Bolting Considerations

If the flow computer installation requires assembly of a process flange, manifold, or flange adapters, follow these assembly guidelines to ensure a tight seal for optimal performance characteristics of the flow computer.

Only use bolts supplied with the flow computer or sold by Emerson Remote Automation Solutions as spare parts. Refer to the figure for common flow computer assemblies with the bolt length required for proper flow computer installation.

DANGER

EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.

Performing this operation in a hazardous area could result in an explosion.

2.9 Power Modes

To keep power consumption to a minimum, especially for remote sites, the FB2100 can run in two different power modes — Low Power Mode (4 MHz or 8 CPU MHz clock speed) or Standard Power

Mode (60 MHz CPU clock speed).

Low Power Mode

The FB2100 normally runs in low power mode for typical metering applications. The radio Power

Control function (configurable in FBxConnect) switches the flow computer into standard power mode at specific times when serial communications are required, then it reverts to low power mode when the communication period is over. A serial connection to a remote 4088B MVT can occur in low power mode.

The local display (HMI module) with FBxWifi uses additional power. You can configure it in

FBxConnect to shut down after a period of inactivity.

DANGER

EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.

Performing this operation in a hazardous area could result in an explosion.

Point the solar panel surface due south (in the northern hemisphere) or due north (in the southern hemisphere) at an angle determined by the latitude of the site. Table 2-8 shows the angle (from horizontal) at which you should install the solar panel to maximize annual energy output. At most latitudes, you can improve performance by reducing the angle during the summer and increasing the angle during the winter. If no seasonal adjustments in panel direction are needed, then adjust the position for the worst-case December-February angle.

Solar insolation is the amount of solar energy in hours received each day by an optimally tilted panel during the worst month of the year. An insolation rating of one hour means that



Connecting the RTD/PRT

 Wiring a Digital Output to the Optional Relay

 Radio Wiring

I/O in the FB2100 flow computer comes from the integrated multivariable sensor and RTD connector, and the CPU board with one of possible two I/O options. In I/O option 1 the CPU has a single digital output. In I/O option 2 the CPU has two channels individually configurable as either digital inputs (DI), digital outputs (DO) or pulse inputs (PI) and two channels individually configurable as either analog inputs (AI) or analog outputs (AO).

Note

Terminal blocks TB3 and TB4 are unused on the FB2100.

Note

When using a digital output to drive an inductive load (such as a relay coil), place a suppression diode across the load. This protects the DO from the reverse Electro-Motive Force (EMF) spike generated when the inductive load is switched off.

Notes About Power for an External Device Connected to a Flow Computer I/O Point:

If the external device does not include its own integrated power supply, you must provide your own external supply (30Vdc maximum) for that device.

Section 4: Operation

4.1

This section covers the following topics:



Powering Up/Powering Down the Device



Establishing Communications



Communicating using the HMI Module

This section describes day-to-day operation of the flow computer including how to turn it on and off and how to communicate with it.

Powering Up/Powering Down the Device

DANGER

Do not attempt to connect or disconnect power from the unit in a hazardous area. Ensure the area is non-hazardous. Failure to do so could result in an explosion.

4.2

4.2.1

Open the enclosure door.

Terminal block TB2 (pins 1,3,5,7) includes connections for DC power (DCIN+, DCIN-) and battery/ solar power (BATT+, BATT-). The internal battery (which is also used with solar power) has its own internal connectors.

 Plug in TB2 (pins 1,3,5,7) to activate DC or battery/solar power. If your device uses an internal battery and it is not connected, connect it as discussed in 2.8.3 Connecting

Battery Power .

 Unplug TB2 (pins 1,3,5,7) to deactivate DC or battery/solar power.

This turns on (or shuts OFF) power from either an external power supply or the battery pack/solar panel.

Note

When you turn power on, the backlight on the HMI module lights, momentarily turns off and then remains lit while the INPUT LED blinks. After approximately one minute the initialization process finishes and the HMI starts to display live data.

Establishing Communications

The flow computer supports three ways to establish communications: through the host SCADA system, through a local laptop computer running FBxConnect, or through the HMI module.

Communicating with the SCADA Host

Communication to the flow computer through a SCADA host computer requires you to configure the host computer software, which varies depending upon whether you are using OpenEnterprise

Operation 73

Emerson FB2100 Flow Computer Instruction Manual

D301783X012

August 2020 or another host software package. Much of this configuration is beyond the scope of this topic, but no matter which host you are using, there are certain steps you must take:

Decide how the SCADA host should communicate with the flow computer. This could be through connection with one of the communication ports. A serial port connection could be a cable directly connected to the SCADA host or there could be intermediate connections through a radio or modem.

Decide which communication protocol you will use. This could be DNP3, ROC, Modbus, or

BSAP. See these documents for more information:

 Emerson FB Flow Computer DNP3 Protocol Specifications Manual (D301806X012)



ROC Protocol Specifications Manual (for Emerson FBx-series) (D301828X012)

FBxConnect Configuration Software User Manual (D301850X012)

 BSAP Communication Guide for FB1000/FB2000 Series Flow Computers (D301808X012)

Provide the SCADA host with information about the various parameters it needs to extract from the application running in the flow computer. Typically, the SCADA host software includes a utility that allows you to identify this information so it can be incorporated into the database at the SCADA host.

Using whatever human-machine interface (HMI) tools exist for the SCADA host, create graphical displays or reports that include the parameters from the application required for successful operator interaction (setpoints, flow variables and so on).

4.2.2 Communicating with a Laptop Using One of the Serial Ports

To communicate with a laptop using a serial port:

 Your laptop must have Field Tools software with FBxConnect software installed.

 You must know a valid username/password combination for the flow computer.

If the flow computer is not awake, you must wake it up first. (See Section 4.3

)

DANGER

EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.

Performing this operation in a hazardous area could result in an explosion.

Connect a cable between a serial port (or serial/USB adapter) on your laptop and port COM2 on the flow computer.

Launch Field Tools and add a new serial connection for this device; this launches FBxConnect configuration software. (If you already have an existing saved serial connection for this device in Field Tools, just double-click on it in the Connections list.)

Log into the flow computer if prompted.

Use the FBxConnect configuration software to view or change any desired parameters.

When finished, log off the flow computer and disconnect the cable from its serial port.

Communicating with a Laptop Wirelessly with FBxWifi

You must have purchased the flow computer with the optional FBxWifi feature in order to connect to a laptop PC wirelessly. Additionally:

 Wi-Fi ® must be configured and working on your laptop PC.

 Your laptop PC must have Field Tools software with FBxConnect installed.

 You must know a valid username/password combination for the flow computer.

 You must know the name of the wireless network and the security key required to connect to it.

 Your laptop PC must be within line-of-sight with either the front display of the flow computer or of an external antenna for the FBxWifi communications module.

 If the flow computer is not awake, you must wake it up first. (See Section 4.3

)

WARNING

Ensure that you and your laptop PC are in a non-hazardous area.

Launch Field Tools software and add a new wireless connection. (If you already have a saved wireless connection for this device in Field Tools, double-click on the device in the

Connections list and skip to step 4.)

Select the wireless network to which the flow computer belongs and enter the appropriate security key.

Click Connect to start the FBxConnect software.

Log into the flow computer if prompted.

Use the FBxConnect software to view or change any desired parameters.

When finished, log off the flow computer and disconnect from the wireless network.

Communicating Using the HMI Module

You must have purchased the flow computer with the HMI module version that includes the optional display. Not all models include the display. Units without the display still include a button to wake up the device and status LEDs.

Notes

 If the device is configured to require logins to view data, you must know a valid username/password combination for the flow computer.

 To conserve power, the HMI module enters sleep mode after a period of inactivity. Sleep mode disables FBxWifi communication. In FBxConnect, you can configure the number of minutes of inactivity triggering sleep mode through the LCD Sleep Time parameter. Setting this parameter to 0 disables sleep mode which keeps the HMI module on but uses significantly more power.

The operator wakes up the device by holding a finger against the front cover glass over the

Emerson FB2100 Flow Computer Instruction Manual

D301783X012

August 2020

Hold to Wake button (the left-most button) typically for five to ten seconds. You can also predefine a number of automatic wake up times during the day from the Power Control screen in

FBxConnect. Exercise care because the more frequent (or more lengthy) the wakeup time, the greater the power usage and the greater the reduction in battery life.

To temporarily keep the HMI module out of sleep mode, maintain an active FBxConnect connection. As long as communications remain active, the HMI module does not sleep

Go to the front of the flow computer and touch your finger on the glass above the Hold to

Wake button until the display lights up. (This may take several seconds.)

Upgrading System Firmware

To maintain hazardous location certifications, you can only replace components in the field with the exact same part so that the model string on the data plate remains correct. This means you cannot add any hardware not reflected in the model string or upgrade a hardware component to a newer version; any such upgrades are prohibited and void the hazardous location certification.

For a list of user serviceable parts contact your Emerson Remote Automation Solutions sales representative or Emerson Impact Partner.

This chapter describes the service tasks that everyone needs to know such as replacing batteries or installing a firmware upgrade. A separate series of field replacement guides covers major field replaceable components.

Any replacement not covered in this chapter or in the field replacement guides (such as adding or upgrading hardware or replacing sensors) can only be performed at an Emerson-authorized repair facility.

Important

Use only batteries supplied with the flow computer or sold by Emerson as spare parts for this flow computer. If you substitute a battery you obtain elsewhere you will void your certification unless it is the identical part from the same manufacturer as that supplied with the flow computer from

Emerson.

Removing/Replacing the SRAM Battery

A lithium coin cell battery provides backup power for the SRAM and the real time clock. The SRAM backup battery can last for up to 10,000 hours of cumulative operation, and only runs if the main power system fails. You do not need to power down the unit to replace the SRAM backup battery.

Important

If the unit is ever powered down without the SRAM battery installed, SRAM data is lost. Always back up your data before you remove the SRAM battery if you know that main power will also be off.

Important

Replacement SRAM backup batteries must be Rayovac® Model BR2335.
