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.

Introduction

Emerson FB1200 Flow Computer Instruction Manual D301782X012
November 2020
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 1-5: HMI Module with LCD

Figure 1-6: HMI Module without LCD

1.10

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 1-6).
FBxWifiTM 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.

Introduction

9

Emerson FB1200 Flow Computer Instruction Manual D301782X012 November 2020
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.

1.11 1.12

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

General Wiring Guidelines
The flow computer's pluggable terminal blocks use compression-type terminals.
The 5.08 mm pitch terminal blocks accommodate wire between 28 and 12 AWG; the 3.81 mm pitch terminal blocks accommodate wire between 28 and 14 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.
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.

Power Modes
To keep power consumption to a minimum, especially for remote sites, the flow computer can run in two different power modes: Low Power Mode (4 or 8 MHz CPU clock speed) or Standard Power Mode (60 MHz CPU clock speed).
Low Power Mode
The flow computer 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 specified 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.

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.
The mounting brackets allow you to adjust the solar panel for maximum solar exposure. You can adjust the swivel of the panel by adjusting the U-bolt.
Figure 2-27: Adjusting Solar Panel Tilt Angle

 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 2-6 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/m2 per day). This rating varies from less than one hour in northern Canada to more than six hours in the Sahara Desert.

Section 3: I/O Configuration and Wiring
This section covers the following topics:  Analog Inputs  Analog Outputs  Digital Inputs  Digital Outputs  Pulse Inputs  Connecting the RTD
 Connecting a Rosemount 4088B Transmitter For Use in a Second Meter Run
I/O in the flow computer comes from the integrated multivariable sensor and RTD connector, the CPU board, as well as from the optional 6-channel expansion I/O board.
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.

This section describes day-to-day operation of the Emerson FB1200 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.
1. Remove the front end cap.
2. 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 2.12.3 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.
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 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:
75

Emerson FB1200 Flow Computer Instruction Manual D301782X012 November 2020
1. Decide how the SCADA host should communicates 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. An Ethernet port connection must be through an Ethernet switch with an appropriate Category 5 shielded patch cable.
2. 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 Emerson FBx-series) (D301828X012)
 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)  Your laptop must have Field Tools software with FBxConnect software installed.  You must know a valid username/password combination for the flow computer.
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.

You must have purchased the flow computer with the optional FBxWifi communcations feature 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.
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, just 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.

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 "awakens" the device by holding a finger against the front cover glass over the Hold to Wake button (the left-most button) for typically 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.

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

1. 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.)

Section 5. Service and Troubleshooting
This section covers the following topics:
 Returning the Unit for Repairs  Interpreting the Status LEDs  Switch and Buttons  Removing/Replacing the HMI Module  Replacing the Main Battery Pack  Removing/Replacing the SRAM Battery  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.
