Enhanced AFC for ControlLogix

Description

Enhanced Liquid & Gas Flow Computer for ControlLogix®

ProSoft Technology’s in-chassis flow computer solution allows you to monitor gas and liquid meters for flow rates, accumulator values, and other calculation results. All alarm data is displayed on our configuration screens.

This solution eliminates the need for multiple RTUs and standalone flow computers for a multi-well pad application. This solution reduces support and maintenance costs as well as helping to decrease your capital spend. This simplified solution allows you to optimize your resources.

In addition, our flow computer sits in a ControlLogix® system, allowing you to take advantage of Rockwell Automation’s distributed I/O capability and ProSoft’s wireless radios to greatly reduce wiring to your transmitters and I/O devices.

Features and Benefits

• Meter runs: The module can calculate up to 16 meter runs with four streams per run simultaneously, making it cost-effective, since more meters can be connected to a single flow computer.
• Modbus capabilities: Remote configuration and diagnostics via Ethernet (Modbus® TCP/IP). Flexible serial port configurations allow for either two Modbus slave ports or one Modbus slave and one Modbus Master port. All data, including configuration, calculated results, and historical archives, are available using either the Modbus TCP/IP server or Modbus slave serial ports.
• Customized Modbus Data Mapping: Remapping to a virtual slave enables data concentration, reducing bandwidth load on the communication system.
• Auditability: Our configuration software provides the ability to download and view archives and events. Audit Scan captures process inputs and calculated results as “snapshots”, allowing verification of calculations. The Event Log records significant events and alarms. Hourly and daily archives are configurable historical records of user-selected data. The data can be viewed online, printed, or saved to a file in .txt or .csv format. Archive data can be exported to Flow-Cal .cfx format. Meter calibration and verification are stored on the module.
• Meter proving: Allows for meter proving with 3 configurable prover types.
• Security: Password protection schemes are available to control user access and log meter calibration and verification activities.

Configuration

The EAFC Manager is a Windows 7-based configuration, reporting, and monitoring tool provided with all E-AFC modules. Project configurations may be uploaded, downloaded, and saved to the PC under user-selectable file names.

Specifications

• The module is recognized by the processor as an Input/Output module
• The included Add-On Instruction (AOI) files are used for data transfers between the module and processor, reducing configuration time
• Configuration is downloaded over Ethernet by way of the Modbus TCP/IP servers, or delivered by user-defined ladder

Functional Specifications

The MVI56E-AFC module operates as a powerful flow computer module, augmenting the operation of the ControlLogix® processor by providing a dedicated and accurate set of flow calculations.

• Calculates flow rates, accumulated volumes, accumulated mass, and accumulated energy
• Calculation results are transferred to processor memory and may also be transferred to a SCADA host using Modbus serial or Modbus TCP/IP
• User-configurable, allowing each of the meter runs to be individually set up to meet the specific requirements of an application
