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.

Figure 1-3: HMI Module with LCD

Figure 1-4: HMI Module without LCD

Note

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

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.

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.

8 Introduction

1.9.1 FBxWifi Antennas

FBxWifi supports two antenna options:



Option J1 uses the internal antenna located inside the HMI module. This option has a line-ofsight range of approximated 100 ft (30 m) from the front of the flow computer or 60 ft (18 m) from the back and sides of the flow computer.



Option J2 uses a factory-installed external antenna. This option has a line-of-sight range of approximately 300 ft (90 m) from the flow computer in all directions. This option is available with either Class 1 Div 2

Autonomous Measurement Mode

You can configure the FB1100 Flow Computer to operate as a low power measurement device that operates independently for one year. In this autonomous measurement mode, the flow computer operates similarly to earlier generation chart recorders, collecting data from non-critical, low-flow applications and storing it for later retrieval.

Autonomous measurement mode supports collection of data from the multi-variable sensor and RTD only. This mode requires the lithium battery pack; no external power supply is required.

You can interact with the device through the HMI module's infrared buttons or through a laptop running FBxConnect. To maintain low power consumption for the battery, using this mode limits you to 30 minutes of interaction per month.

See Appendix E for more information.

Retaining Clamp

D301752X012 May 2022

2.5 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.

2.6 Front or Rear End Caps

The flow computer includes two threaded covers (end caps). The front end cap includes a window for viewing the HMI module; the rear end cap provides access to the terminal plate for power and I/O wiring.

2.6.1 Removing/Replacing Retaining Clamp on End Caps

For flameproof ATEX/IEC applications, each end cap includes a retaining clamp which screws down to prevent the end cap from being unscrewed.

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.

3.1 Powering Up/Powering Down the Device

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.

Remove the front end cap.

Terminal block TB1 includes connections for DC power (+DCIN, -DCIN) and solar power

(+SPIN, -SPIN). Battery power (which is also used with solar power) has its own internal connections.



Plug in TB1 to activate DC or solar power. If your device uses an internal battery and it is not connected, connect it as discussed in Section 2.12.2 Connecting Battery Power.

Unplug TB1 to deactivate DC or solar power. If your device uses an internal battery, disconnect the main battery.

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.

3.2 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.

3.2.1 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 41

Emerson FB1100 Flow Computer Instruction Manual

DANGER

D301752X012 May 2022

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, or BSAP. See

these documents for more information:



Emerson FB Flow Computer DNP3 Protocol Specifications Manual (D301806X012)



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



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).

3.2.2 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.

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.

Appendix E: Autonomous Mode Requirements

The FB1100 Flow Computer operating in “autonomous mode” runs off a single battery for up to 12 months without recharging. The 12-month battery life is based on the FB1100 running in low power mode on a typical remote application with a local collection of history and use of the optional display for up to 30 minutes per month. This configuration makes the FB1100 an ideal replacement for chart recorders, significantly reducing measurement uncertainty and providing a complete electronic audit trail. The 12-month battery life is achieved under an ambient

temperature of 25

The solar powered option provides up to 25 days of autonomous operation without charge.

To achieve 12 months of autonomous operation, you must configure the FB1100 Flow Computer to meet the following requirements:

C/77oF; refer to Table E-2.

If you exceed these requirements, the FB1100 Flow Computer autonomous operation.
