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-of- sight 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

Emerson FB1100 Flow Computer Instruction Manual

February 2021

Software Tools

FBxConnect provides a series of wizards that allow you to perform configuration activities for the flow computer. You connect a PC running FBxConnect 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

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.

2.5General 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.

2.6Front 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.

2.6.1Removing/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.
