1.8 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 displays the current values of particular process variables. A configuration parameter in FBxConnect determines whether you must first log in 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.

Figure 1-4. HMI Module with LCD

Figure 1-5. HMI Module without LCD

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).

1.9 FBxWifi™ Communications

The flow computer has an optional Wi-Fi® transceiver (FBxWifi) that enables you to connect via a laptop or tablet from a distance. The distance supported varies depending on the laptop/tablet

type and environmental conditions but is typically 70 to 100 feet from the front of the flow computer and 40 to 60 feet from the side and rear of the flow computer.

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.

1.10 Software Tools

The FBxConnect configuration software provides a series of wizards that allow you to perform configuration activities for the flow computer. You connect a PC running the FBxConnect configuration software to the flow computer using one of the communication ports or through a wireless connection. You can then:

Holes in the door latches of the fiberglass enclosure allow you to attach a wire seal.

Alternatively, you can use a pan head screw (#10-32 X 0.81 316 SS or Monel alloy 400) with an Oring (0.15 ID, 0.07 W) in place of one or both door latches to screw the door shut. In this case, you pry off the latch with a flat head screwdriver and pop out the mating cap to free up the holes for the screw.

Figure 1-7. Removing Cap and Latch from Fiberglass Enclosure

For ATEX/IEC-compliant installations with the fiberglass enclosure, you must use one of these three choices (padlock, wire seal, or screw).

For either enclosure type, you may apply tamper-evident tape to the four sensor coupling screws and two rotation set screws to provide evidence of unauthorized sensor adjustments. The four coupling screws also include holes through which you could attach a wire seal.

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.

20 Installation

2.6 Grounding

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

Figure 2-7. Ground Stud

 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).

2.9 Power Modes

To keep power consumption to a minimum, especially for remote sites, the FB2200 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 FB2200 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.

Important

You must disable the Ethernet port (using a jumper) to run in low power mode. See Section 2.13.3.



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 the site, on average, would receive one hour of solar energy at the panel's rated power level (1000W/m than six hours in the Sahara Desert.

I/O in the FB2200 flow computer comes from the integrated multivariable sensor and RTD connector, the CPU board, as well as the optional mixed I/O modules.

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.

If your FB2200 flow computer includes the optional 8-channel Expansion I/O Module, you may be able to use the 24V loop power terminals to power the external device. In this case, the load current

cannot exceed 500 mA.

3.8 Wiring a Digital Output to the Optional Relay

The flow computer supports two optional electro-mechanical relays for switching on/off external circuits or devices. If you order this option, the relays ship from the factory mounted to the top of the battery compartment inside the flow computer enclosure.

You can wire a relay to an isolated DO (Figure 3-18). You must also use the isolated GND and provide 24V to power the relay. To attach a wire, insert it into the connector and tighten the adjacent screw to secure it. The NO and COM wires go to the external circuit or device.

Figure 3-18. Relay Wired to Isolated DO

D301784X012

November 2020

Alternatively, you can wire a relay to a non-isolated DO (Figure 3-19). In that case, you must use the non-isolated GND and provide 24V to power the relay. To attach a wire, insert it into the connector and tighten the adjacent screw to secure it. The NO and COM wires go to your external circuit or device.

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.

4.1 Powering Up/Powering Down the Device

D301784X012

November 2020

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.

1. Open the enclosure door.

2. 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.



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.

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.

4.2 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.

4.2.1 Communicating with the SCADA Host

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

Operation 83

Emerson FB2200 Flow Computer Instruction Manual D301784X012 November 2020

1. 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.

2. Decide which communication protocol you will use. This could be DNP3, ROC, Modbus, or BSAP. See these documents for more information:



DNP3 Protocol Specifications Manual (for FB1000 and FB2000) (D301806X012)



ROC Protocol Specifications Manual (for Emerson FB Series Flow Computers)

(D301828X012)



FBxConnect Configuration Software User Manual (D301850X012)



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

3. 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.

4. 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



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



4.3 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.

To temporarily keep the HMI module out of sleep mode, maintain an active FBxConnect

connection. As long as communications remain active, the HMI module will not sleep



In order 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. This chapter describes the service tasks that everyone needs to know such as replacing batteries or installing a firmware upgrade. For other field replacements, see the appropriate field replacement guides for that component. Any replacement not covered in this chapter or in the field replacement guides can only be performed at an Emerson-authorized repair facility.
