EFM ABB Totalflow Module

Retrieves EFM ABB Totalflow data

This module serves as a driver for Ignition, communicating with ABB Totalflow computers, including G2 Late, G3, G4 Early, G4 Late, and G5 models. By utilizing the EFM ABB Totalflow module on the Ignition platform, data from ABB Totalflow EFMs is retrieved and made available as tags in the OPC browser.

Additionally, the module monitors and collects alarm, event, and historical logs or Quantitative Transaction Records (QTR) for transmission to the enterprise or other flow calculation services.

Using MQTT with the EFM ABB Totalflow module

The true power of this solution can be realized by integrating the EFM ABB Totalflow module with Cirrus Link’s MQTT modules. By deploying Ignition or Ignition Edge with the EFM, ABB Totalflow polling is distributed to the network edge, optimizing bandwidth usage over radio or other IP networks, thus enhancing SCADA data response times. Below are typical architectural solutions when utilizing the EFM ABB Totalflow Module.

Using the highly efficient MQTT protocol, only event changes are sent to the host. This means that real-time SCADA data is transmitted only upon change, while alarms, events, and QTR (Quantitative Transaction Records) are sent only when available.

In legacy protocols, complex sequences of registers have been used for years to transmit data, essentially creating a log of information. These methods are prone to issues with data integrity and require frequent polling of a host across the network to check for new events. With the EFM ABB Totalflow module, data such as alarms, events, and QTRs are extracted from the flow computer and placed in an MQTT record as an immutable object with a timestamp and checksum, then sent directly to a database table at the host. The MQTT Recorder module is required for delivering MQTT records.

Benefits of this module when used with MQTT modules:

• Supports G2 Late, G3, G4 Early, G4 Late, and G5 voor real-time SCADA data and all EFM data
• Automatic detection configuration
• Runs on Ignition and Ignition Edge platforms
• Accessible from any AAR, even from user programs
• Supports alarms, events, daily history, and periodic history records
