Emerson ROC Device Connection

Device connection for Emerson ROC module can be configured via OPC UA configuration.  Begin by selecting OPC UA → Device Connections on the left as shown below:

This opens respective configuration page as shown below:

New Emerson ROC device can be created by following the 'Create new Device...' link and choosing 'EFM Emerson ROC' device as shown below:

This opens the 'New Device' configuration mage for EFM Emerson ROC Device. The configuration sections available are Emerson ROC Device Connection, Emerson ROC Device Connection, Emerson ROC Device Connection, Emerson ROC Device Connection, Emerson ROC Device Connection, Emerson ROC Device Connection, Emerson ROC Device Connection and Emerson ROC Device Connection Settings.

  • Minute History Scan Rate
    • The rate in seconds that minute history records are scanned. Set to -1 to disable minute history scanning. Default is -1
  • Periodic History Scan Rate
    • The rate in seconds that periodic history records are scanned. Set to -1 to disable periodic history scanning. Default is -1
  • Daily History Scan Rate
    • The rate in seconds that daily history records are scanned. Set to -1 to disable daily history scanning. Default is -1

  • History Time Stamp
    • Checkbox to enable history time stamp. Selected by default.
    • If enabled the history time stamp will be at the beginning of the period (leading), otherwise at the end of the period (trailing)
  • Read Delay
    • The Polling Read Delay in milliseconds when polling response may be slow (recommend when using a terminal server). Default is 0 milliseconds
  • Poller Watchdog Rate
    • The rate in seconds that the poller watchdog thread is executed to verify polling threads are running. Set to 0 to disable the poller watchdog. Default is 0 seconds.



With the device now established you must configure the specific global TLP Definitions associated with the device, create TLP Templates and TLP Poll Groups to use.  

Specifying TLP Definitions for a Device

With the device now established the specific global TLP templates that are appropriate for this device must be associated with it.  Do so by clicking the 'More' drop-down button and selecting 'TLP Definitions' as shown below.

You should now see an empty list of TLP definitions (unless you used the "Add All TLP Definitions" setting).

Click the 'Add Row' link that is shown below.  This will show a new TLP definition with a select box to allow you to select which global TLP definition you want to associate with this device.  Add as many as are appropriate for your device as shown below.

When complete, save the list and you will be taken back to the Devices list.

Creating TLP Templates for a Device

With the TLP definitions now defined for this device we can create some TLP templates to allow creation of TLP poll groups.  To create a TLP template, click on the 'More' drop-down menu and select 'TLP Templates' as shown below.

To add a TLP template, click the 'Add Row' link shown below.

Give the new TLP template a name that makes sense and then click the 'Edit TLP Template Contents' link next to the name field shown below.

Add your new TLPs by clicking the 'Add Row' link shown below.

Note there are six fields available for each row of which only three can be modified.  These are:

  • T
    • The 'T' parameter of the TLP
  • P
    • The 'P' parameter of the TLP
  • Access
    • The access for this value - either RO for 'read only' or RW for 'read/write'
    • Cannot be modified here.  It is defined in the global TLP definition CSV file.
  • Data Type
    • The data type for this TLP
    • Cannot be modified here.  It is defined in the global TLP definition CSV file.
  • Parameter Name
    • The descriptive name of this TLP
    • Cannot be modified here.  It is defined in the global TLP definition CSV file.
  • Tag Name
    • The tag name that will show up in Ignition for this TLP.
    • The default value comes from 'Parameter Abbreviation' of the global TLP definition CSV file.  It can be changed here to any value.

The TLPs available to be added are based on the TLP definitions that have been made available to this specific device.  Add as many templates that make sense to be grouped together in a logical group.  When complete you should see something similar to what is shown below.  Click the 'Save' button.

Creating TLP Poll Groups for a Device

With TLP templates already defined you can now create TLP poll groups which will poll a group of TLPs via a TLP template at a specific logical number at a specified rate.

Do so by selecting 'TLP Poll Groups' via the 'More' drop-down as shown below.

To add a TLP poll group, click the 'Add Row' link shown below.

Now you can give the new TLP poll group a name that makes sense. Then click the 'Edit TLP Poll Group Contents' link next to the name field shown below.

At this point you can create a poll group using one or more TLP templates as shown below.  The parameters that must be set here are:

  • TLP Template Name
    • The TLP template to use for this poll group
    • The TLP templates available to choose from are based on the TLP templates defined for this device
  • Logical Number
    • The 'L' parameter of this TLP template.
  • Tag Folder Path
    • The tag folder path to use as the base for all TLP tags in this TLP template.
  • Scan Rate
    • The rate (in seconds) at which to poll all of the TLPs in this TLP template.

When complete, click the 'Save' button to save the TLP poll group.

Create as many TLP poll groups as you'd like.  Once complete, click the 'Save' button at the bottom of the page below.
