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 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 1-4. HMI Module with LCD

Introduction 7

Emerson FB2100 Flow Computer Instruction Manual D301783X012 May 2022

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 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.

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:



Set parameters within your application



Configure I/O channels



Specify the serial communication method for a port (RS-232 to RS-485) as needed



View or collect audit trail information such as alarm, event, or historical logs



Update system firmware

1.13 Secure Gateway

For enhanced data security when using an IP/Ethernet connection or a serial connection into an IP terminal server, Emerson Remote Automation Solutions recommends adding an industrial router with VPN and firewall security. Recommended solutions include the MOXA EDR‐810, the Hirschman Eagle One, or the Phoenix mGuard rs4000 (or equivalents). An example of how to install one of these devices to the RTU can be found in the Emerson Remote Automation Solutions MOXA® Industrial Secure Router Installation Guide (part number D301766X012).

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 Grounding

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

18 Installation

Emerson FB2100 Flow Computer Instruction Manual

D301783X012

May 2022

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).

2.7 Opening/Closing the Enclosure



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.

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

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

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 you to configure 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 71

Emerson FB2100 Flow Computer Instruction Manual D301783X012 May 2022

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:



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)

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

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.

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

2. 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.)

3. Log into the flow computer if prompted.

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

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

4.2.3 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.



72 Operation

Emerson FB2100 Flow Computer Instruction Manual

WARNING

D301783X012 May 2022



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)

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

1. 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.)

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

3. Click Connect to start the FBxConnect software.

4. Log into the flow computer if prompted.

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

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

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 wake the device, hold a finger against the front cover glass over the Hold to Wake button (the left-most button) typically for five to ten seconds. You can also pre-define 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
