The TLPs available to be added are based on the TLP definitions that have been made available to this specific device.  Add TLPs 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.

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

  • Cannot be modified here.  It is defined in the global TLP definition CSV file.

With TLP templates already defined you can now create TLP poll groups which will poll the Emerson ROC device 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.
