Electronic Flow Measurement Modules for Ignition

Electronic Flow Measurement (EFM) is the cash register for the Oil & Gas industry for measuring hydrocarbons to calculate production and revenue. Major industry flow computer devices gather the EFM data but represent it very differently within their proprietary protocols making the process of extracting this data and sharing its true value throughout the enterprise a challenge. Cirrus Link has developed a range of EFM module products for the Ignition platform to extract this EFM data using the efficient open standard MQTT protocol to solve this problem and provide the following benefits.

EFM Emerson ROC Module:

This module communicates with Emerson ROC and ROC Plus flow computers, formerly Fisher ROC. This includes, but not limited to, FloBoss 100 Series and ROC 800 series. By using the EFM Emerson ROC Module on the Ignition platform the Emerson ROC EFM data is polled and made available as tags within the OPC browser. Support for Opcode Tables simplifying configuration.

EFM ABB Totalflow Module:

The EFM ABB Totalflow module is a protocol driver for the SCADA platform, Ignition, by Inductive Automation. This module communicates with ABB Totalflow computers including G2 Late, G3, G4 Early, G4 Late, and G5. By using the EFM ABB Module on the Ignition platform the ABB Totalflow EFM data is polled and made available as tags within the OPC browser.

MQTT Recorder Module:

The MQTT Recorder Module receives record objects from the MQTT Engine Module that have arrived via MQTT/Sparkplug. Utilizing a database that is configured within Ignition, the MQTT Recorder Module automatically generates database tables and populates the rows within the tables with records as they are received. Records represent a collection of tags, fields, and key-value pairs. They are especially useful for receiving records from a flow computer for its events, alarms, and history data.

Like all Ignition modules, the IIoT modules can be installed, removed, and upgraded without impacting operations or affecting the rest of the system.

EFM Emerson ROC Module

The EFM Emerson ROC module is a protocol driver for the Ignition OPC UA module, by Inductive Automation. It communicates with Emerson ROC and ROC Plus flow computers, formerly Fisher ROC. This includes, but not limited to, FloBoss 100 Series and ROC 800 series. By using the EFM Emerson ROC Module on the Ignition platform the Emerson ROC EFM data is polled and made available as tags within the OPC browser.

EFM Emerson ROC Module uses T,L,P addresses to access data from standard and custom applications running on the flow computer. With the ability to load custom TLP libraries into the protocol module, custom configurations can be created and quickly replicated across entire populations of deployed devices.

The EFM Emerson ROC Module also polls and gathers Alarm, Event and QTR (Quantitative Transaction Records) records for onward transmission to the enterprise or other flow calculation services.

Using MQTT with the EFM Emerson ROC Module

By coupling the EFM Emerson Protocol with the power of the MQTT modules by Cirrus Link the real power of this solution can be realized. By installing Ignition or Ignition Edge with the EFM Emerson ROC polling is distributed to the edge and increase bandwidth utilization over radio or other IP networks providing increased response times of SCADA data. Please find below the typical architecture solutions when using the EFM Emerson ROC Module.

Using the highly efficient MQTT protocol only event changes are transmitted to the host. The benefit this gives is that the real time SCADA data is transmitted on change, while continuously monitoring for Alarms, Events and QTR records to be sent only when available.

For years complex sets of registers have been used in legacy protocols to send data that is essentially a record of information. These methods are prone to problems with keeping the data together and require a lot of polling from a SCADA host over the network to monitor for new events. With the EFM Emerson Protocol module data such as Alarms, Events and QTR’s are extracted from the flow computer and put into an MQTT Record as an immutable object with a time stamp and checksum then sent straight to a database table at the host. For delivering MQTT Records, the MQTT Recorder module is required. Please go here for more information on the MQTT Recorder Module.

EFM ABB Totalflow Module

EFM ABB Totalflow Module

The EFM ABB Totalflow Module is a protocol driver for the SCADA platform, Ignition, by Inductive Automation. This module communicates with ABB Totalflow computers including G2 Late, G3, G4 Early, G4 Late, and G5. By using the EFM ABB Totalflow Module on the Ignition platform the ABB Totalflow EFM data is polled and made available as tags within the OPC browser.

The EFM ABB Totalflow Module includes the DB2 FCU subsets of both Register as well as Data Structure aspects of the protocol (DB2 Trending will not be supported as this function is now achieved at a higher level in the system). The EFM ABB Totalflow Module uses AAR addresses to access data from standard and custom applications running on the flow computer. The module also uses an “Auto-Discovery” mode on startup or reconfiguration to obtain information about applications running on the Totalflow. The driver will then use .ini files supplied from ABB to auto-configure the array-register definitions and create default poll groups for all enabled applications. This significantly reduces the configuration time and amount of errors in setting up the polling. With the ability to load custom AAR libraries into the protocol module, custom configurations can be created and quickly replicated across entire populations of deployed devices.

The EFM ABB Totalflow Module also polls and gathers Alarm, Event, and Historical Logs,or Quantitative Transaction Records (QTR) records for transmission to the enterprise or other flow calculation services.

MQTT Recorder Module

For years data has been created in PLC’s and RTU’s that represent a record of information such as a quantitative transaction record (QTR) from a flow computer. With the limitations of register based communication protocols this information has always been clumsily handled as consecutive blocks of registers. This method runs the risk of not keeping all the data together as a record event, when a partial subset of the registers get overwritten with a newer set of information. Today with the power of MQTT these records of data can be published, on event, as an immutable record which automatically builds and populates a table within a database. In addition this record can be time stamped and carry a SHA-256 Hash key that will guarantee that the entire contents of the record are unedited from source. The MQTT Recorder module receives these records and first automatically builds the database table, and then populates each record into the table as it is received.

Examples of the records are:

Oil & Gas – EFM Quantitative Transaction Records (QTR’s), EFM Alarms, EFM Events, P’cards for Pump of Controllers
Pharmaceutical – Batch records for drug manufacture
Transportation Industry- Locomotive engine events

The diagram below shows an example of the record flow of data for the MQTT Recorder with the EFM Emerson ROC Module. The EFM Emerson ROC module polls locally on Ignition or Ignition Edge Platform for the events, alarms and history records on the flow computer. MQTT transmission publishes the record to the MQTT Server. MQTT Engine on the Primary Ignition Gateway subscribes to the MQTT Server to receive the record. The MQTT Recorder Module works in unison with the MQTT Engine module to receive the record and puts the record data into table within the SQL database.

Benefits

The MQTT Recorder offer the following benefits:

Creates tables for any record formatted data in Ignition supported databases
Guaranteed records with hash-based message authentication code
Supports store and forward at the Edge eliminating lost data on coms outage
