Hardware Architecture
Base and Extension Units
The FB3000 features polycarbonate resin base and extension chassis with a removable wire guard for terminal protection. Optional DIN rail mounting is available. Rugged housings are suitable for the extended temperature range. Advanced short-circuit protection safeguards the CPU, I/O, and communications modules, reducing maintenance needs. Internal 3.3-volt electronics optimize power consumption, utilizing power blocks for external input power conversion.
Backplane and Chassis
The FB3000 backplane supports a central processing unit (CPU), two power input blocks with automatic fail-over, up to 31 input/output (I/O) modules, and up to 31 connection (personality) modules. Personality modules provide surge protection and tailor I/O to site needs, interfacing with field wiring. The base backplane can be extended to support up to four chassis in total, with each additional chassis supporting up to eight I/O modules without requiring an additional CPU or power supply (if power requirements are under 5 Amps). Refer to the Emerson FB3000 Remote Terminal Unit (RTU) Instruction Manual (D301851X012) for specific power limitations and hazardous area approvals.
Memory
The FB3000 supports three types of memory:
- Flash: Stores firmware image, history, alarms, events, and file system.
- SRAM (Static Random Access Memory): Used for Data Logs and configuration.
- DDR3 SDRAM (DDR3 Synchronous Dynamic Random Access Memory): Used for firmware and execution memory.
A 32-bit microprocessor and Real-Time Operating System (RTOS) provide hardware and software memory protection.
Firmware
The firmware, residing in flash memory, includes the operating system and application software. It features a database for events, alarms, and history, storing the last 8000 events, 8000 alarms, and six months of hourly records per API Chapter 21.1 (Second Edition, February 2013).

For gas DP and gas linear meters, the firmware provides:
- Indicated volume
- Corrected (standard) volume
- Mass
- Energy
- Integral Value (DP meter) or Pulse Totals (linear meter)
The firmware accepts gas density, base density, and specific gravity from sources including up to 6 gas chromatographs (GC), fixed value, periodic SCADA download, an external analog input signal, or calculated based on gas composition.
For API 12.2 and API 20.1 (low water):
- Indicated Volume / Mass
- Gross Volume
- Gross Standard Volume
- Net Standard Volume
- Water Volume
- Mass
- Flow time
- Pulses
For API 20.1 (high water):
- Indicated volume / mass
- Gross Volume
- Oil (Unshrunk and Theoretical Production)
- Natural Gas Liquid
- Flashed Gas
- Water (Uncorrected and Corrected Volume)
- Flow Time Total
- Pulses
The firmware can accept water cut from on-line or off-line analyzers, corrected to metering conditions. It supports a fallback mode for questionable process variable values, with options to use the last good value or a fixed fallback value.
Meter Runs and Stations
The FB3000 optionally supports up to 36 meter runs with station support. Meter runs can be grouped into stations for simplified configuration, with parameters set once for the entire station. This reduces redundant data. Gas meters can be assigned to gas stations, and liquid meters to liquid stations. Contract hours can be set per station.
Control
The FB3000 supports up to 100 instances of control, including PID, action blocks, effects, and math blocks. PID control loops can have a primary and an override loop, each with user-defined input, output, and override capability. Action blocks allow monitoring conditions and performing actions based on Boolean logic statements. Effects trigger actions when action blocks are true, configurable by defining output parameters and values. Math blocks perform mathematical equations using user-defined variables, supporting standard functions, constants, and operators with double-precision floating-point math.
Communications
The FB3000 provides up to seven communication ports: four serial interfaces (Comm 1-4), two Ethernet ports (Comm 5-6), and one USB port (Comm 7). The USB port serves as a local operator interface (LOI). Supported serial types include EIA-232 (RS-232) and EIA-422/EIA-485 (RS-422/RS-485). The FB3000 supports DNP3 and Modbus (host and slave, ASCII or RTU) protocols on all serial and Ethernet ports; USB supports only DNP3. Ethernet ports also support Modbus encapsulated in TCP/IP.
Power Input Blocks
Power Input blocks provide external power to the RTU, accepting input from 10.5 to 30 Vdc. The FB3000 supports two power supply blocks for automatic fail-over, ensuring continuous operation if one fails. Power blocks also support a lithium coin cell battery for SRAM backup.
Inputs/Outputs
Up to 31 isolated I/O modules can be added to meet diverse field I/O requirements. I/O modules are hot-swappable, allowing removal and replacement under power without interrupting operation. The new module automatically acquires the previous module's configuration. Personality modules are replaced using a quarter-turn screw.
Networking and Remote I/O
FBxNet™
FBxNet is a secure, configurable, peer-to-peer communication network for data exchange between Emerson FB3000 RTUs and FB1200/FB2200 flow computers over Ethernet. FB3000 and FB1200/FB2200 can act as publishers, while only FB3000 can be a subscriber.
FBxRemote I/O™
FBxRemote I/O is a remotely mounted chassis that extends FB3000 I/O capabilities. It supports up to 31 I/O slots across four chassis and uses the same I/O modules, chassis, and power blocks as the FB3000. It requires an I/O CPU (3IOCPU) to act as a bridge, enabling communication with the main FB3000. The I/O CPU does not support meter runs, control, or applications but does support serial communication for remote devices like the 4088B transmitter.
Software
FBxConnect
FBxConnect is an easy-to-use Microsoft® Windows®-based program for configuring, calibrating, monitoring, and retrieving historical data from the FB3000. It features Windows-style navigation, context-based dialogs, and task-driven Guided Setup routines. It supports program customization via Action Blocks, Math Blocks, and Effect logic operations for control, mathematical, and logical operations. Security features include password protection for access control.
FBxDesigner
FBxDesigner is an integrated development environment for building IEC 61131-3 compliant programs that can be downloaded to the FB3000. It allows program development independently of FBxConnect and requires an optional software-based license key.
Additional Features
- I/O and Communications: Supports a wide variety of modules for diverse applications.
- Software-based License Keys: Enable access to applications like well optimization and meter run calculations.
- Gas Calculations: Optional license key enables up to 36 gas meter runs using AGA or ISO calculations for various meter types (orifice, turbine, ultrasonic, Coriolis).
- Liquid Calculations: Optional license key enables up to 36 API Chapter 12.2 / API Chapter 20.1 liquid meters using turbine, ultrasonic, or Coriolis meter types.
Alarms and Events
The FB3000 offers extensive alarming capabilities for operational efficiency and audit trails. Alarms can be pre-allocated to meter runs for standard values (pressure, temperature, differential pressure, frequency) or user-defined parameters. The Alarm log stores the most recent 8000 alarms. The Event log stores significant operational events, configurable to store all 8000 events in a single log or split into 4000 metrology events and 4000 operational events.
History
The history database holds up to 640 points in 39 history groups, providing over 240,000 unique entries. History groups can be configured for different archiving intervals (1 second to 200 hours). The FB3000 includes four standard periodic logs (hourly, daily, weekly, monthly) and two user periodic logs. These logs can store up to 610 variables each. The FB3000 with FBxConnect provides pre-formatted EFM reports (.csv, .pdf, secure pdf) and FLOWCAL-compliant .cfx files.
