EFM ABB Totalflow Quickstart

Overview

There are four main types of data that the EFM ABB Totalflow driver is capable of getting from an ABB Totalflow device.  These are:

• Application-Array-Register (AAR) data
• Alarm Data
• Event Data
• History Data

AARs are polled at a specified interval based on a poll rate and then made available via the OPC-UA interface.  Alarms, events, and history are made available to MQTT Transmission to be published as immutable Record objects to an MQTT server.  Typically these would be received by the MQTT Engine and MQTT Recorder modules running on a central Ignition Gateway and inserted into a database for later use or to be made available to other third party systems.

For the purposes of this document there are some definitions that are explained below.

• Array-Register Definitions (Global)
  • The global TLP definitions made available to the EFM Emerson ROC module.  They are uploaded to the Ignition instance in the form of specifically formatted CSV files.  These TLP definitions can be reference by the configurations of the individual ROC devices that they apply to. A single Ignition Gateway may contain multiple global TLP definitions files that are used to configure different device types where the actual point types & parameters of the individual TLPs may differ across the different files and device types.
• EFM Mappings
  • Periodic Mappings
    • The periodic mapping files are used for building up EFM Periodic History Records.  They define which TLPs map to which fields (columns) in an EFM Periodic History Record, the logical type of the point type table (meter, station, or input), and an archive type of the value. They are uploaded to the Ignition instance in the form of specifically formatted CSV files.
