Overview
Overview
Overview

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

...

TLPs 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.

Common File Exchange (CFX) can also be used for these record data.

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

SettingsTLP 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.

Emerson ROC SettingsEFM Configuration Mappings

The configuration mapping files are used for building up EFM Configuration Records. They define which TLPs map to which fields (columns) in an EFM Configuration Record.  Additionally they can provide bit and/or value mappings for the TLP values. They are uploaded to the Ignition instance in the form of specifically formatted CSV files. 

EFM Emerson ROC SettingsEFM Periodic MappingsThe 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.

These are a subset of the global TLP definition files that apply to a specific device.

OPC UA Device ConnectionTLP Templates

TLP templates are logical groupings of TLPs.  Generally TLP templates would be created so that instances of them can be used by specifying a poll group with a logical number (the 'L' parameter in a TLP).

OPC UA Device ConnectionTLP Poll Groups

Poll groups use TLP templates in conjunction with a logical number to create a specific set of TLPs to be polled at a specified poll rate.

There are six basic steps to getting all of the data available from a ROC into Ignition

  1. Define/upload the global TLP definitions available for all ROC devices in this Ignition instance
  2. Define/upload the EFM Mappings for all ROC devices in this Ignition Instance
  3. Create the base device connection to the ROC
  4. Specify the subset of TLP definitions that this specific ROC uses
  5. Create TLP Template(s) which define groups of TLPs should be polled as a logical group
  6. Create TLP Poll Group(s) which specify the logical parameters associated with a given TLP Template
  7. Use Ignition Designer to pull tags into a tag provider

Global TLP Definitions

The EFM Emerson ROC driver module provides a configuration section to the Ignition Gateway.  These can be seen in the Configure section of the Ignition Gateway web UI on the left panel near the bottom.  Note this step is required before any EFM Emerson ROC device connections can be define.  Each Emerson ROC device connection will use a subset of these global TLP definitions to operate.

Once in the configuration screen there will be a link to create new global TLP definitions.  Click the link shown below to create a new one.

When creating a new global TLP definition only a name and a CSV file needs to be specified.  The name can be any unique name that describes the TLPs included in that CSV file.  They can be device specific TLPs or they can be TLPs associated with a specific user program.

EFM Mappings

Configuration Mappings

The configuration mapping files are used for building up EFM Configuration Records.  They define which TLPs map to which fields (columns) in an EFM Configuration Record.  Additionally they can provide bit and/or value mappings for the TLP values. 

These mappings are CSV files with the following values:

  • Column Name
    • The name of the EFM Configuration Record field
  • Column Data Type
    • The datatype of the EFM Configuration Record. Must be one of the following:
      • VARCHAR
      • NUMBER
  • TLP Point Type
    • The 'T' parameter of a TLP - must be an integer
  • TLP Parameter Number
    • The 'P' parameter of a TLP - must be an integer
  • Bits
    • An optional declaration of the bits to use from the value of the TLP
    • An ordered, colon-delimited, list of bit positions
    • Examples:
      • If the TLP value is a byte and only the first (least significant) bit is used, this value would be: 0
      • If the TLP value is a byte and the 2nd and 3rd bits are used, this value would be: 2:3
  • Event Value Mapping
    • An optional, semicolon delimited mapping of the TLP values to the values that will be stored in the EFM Event Record
    • If using only certain bits the values themselves will need to be ordered, colon delimited lists of bit values
  • Config Value Mapping
    • An optional, semicolon delimited mapping of the TLP values to the values that will be stored in the EFM Configuration Record
    • If using only certain bits the values themselves will need to be ordered, colon delimited lists of bit values

Configuration Steps
Configuration Steps
Configuration Steps

There are six basic steps to getting all of the data available from a ROC into Ignition

  1. From EFM Emerson ROC Settings, define/upload the global TLP definitions available for all ROC devices in this Ignition instance

  2. From EFM Emerson ROC Settings, define/upload the EFM Mappings for all ROC devices in this Ignition Instance

  3. From OPC UA Device Connections, create the device connection to the ROC

  4. For this device Connection, specify the subset of TLP definitions that this specific ROC uses

  5. For this device connection, create TLP Template(s) which define groups of TLPs should be polled as a logical group

  6. For this device connection, create TLP Poll Group(s) which specify the logical parameters associated with a given TLP Template

You should see the tags being polled from the ROC device as shown below.  You can use these tags as any standard OPC tags in Ignition.

Viewing Record Data

Record data can be viewed in a couple of ways:

  • Using Common File Exchange (CFX)
  • Publishing as an immutable record object

Using Common File Exchange (CFX)

If using Common File Exchange (CFX), the record data will be stored/maintained in CFX.MD5 files on the local Ignition instance. See the Emerson ROC Device Connection configuration for more details. 

These files can be transferred from the Edge device using any method you choose such as FTP but can also be published using the MQTT Transmission File Publishing option.

To do this, you will need to configure an MQTT Transmission File Record and set the CFX File Transfer parameter to point to that File Record and the CFX files can then be automatically published. See the Creating and Publishing Common Exchange File CFX tutorial for details.

Publish as an immutable record object

To publish To view record data which includes ROC alarms, events, and history data you must have MQTT Transmission installed on the instance with the EFM Emerson ROC driver. 

In addition, the following must be set up.:

At the Central Gateway:

At the Edge Gateway

  • Install and configure Configure MQTT Transmission
    • If you do not have a Transmitter configured, create an MQTT Transmitter and set the Sparkplug Settings to the unique Group and Edge Node ID values generated by the Device Connection configuration.

    • If a Transmitter already exists, for example to publish the polled/live data, you can edit the Group and Edge Node IDs to match the existing Sparkplug Edge Node created by the Transmitter.Add/update the Transmitter configuration and/or the Tag folders so that an Edge Node is reporting with a Group ID, Edge Node ID, and Device ID (for example: G1, E1, D1)
    • Add/update the Server configuration to point to the MQTT server
    • Click the "Transmission Control/Refresh" Tag From Ignition Designer, use the MQTT Transmission 'Refresh' Mechanism to make sure it is connected and reporting.Install and configure
  • Configure EFM Emerson ROC module
    • [IMPORTANT] Must have a Sparkplug Group ID, Edge Node ID, and Device ID specified in the device configuration that matches the Edge Node/Device that MQTT Transmission is reporting on
    • The Alarm, Event, and/or History poll rates in the Emerson ROC driver device configuration must be greater than zero depending on which data you wish to collect.

      Warning

      Must have a Sparkplug Group ID and Edge Node ID specified in the Device Connection configuration that matches a Sparkplug Edge Node that MQTT Transmission is reporting on


When all of these conditions are met, alarm, event, and/or history data will be collected, published, and stored via MQTT Recorder in the configured database.
