A new Emerson ROC device can be created by following the 'Create new Device...' link and choosing 'EFM Emerson ROC' device as shown below and clicking 'Next' at the bottom of the page.

This opens the 'New Device' configuration page for EFM Emerson ROC Device. The configuration sections available are General, Connectivity, Security, Date/Time, Records, Records Signature, Sparkplug and Advanced Settings.

Connectivity

Security

Date/Time

Records Signature

Common Exchange Format (CFX) 

Available in release 4.0.15 or newer


To view all the CFX parameters below, MQTT Transmission must be installed.

MQTT Transmission is not required to create and maintain the CFX files for each meter. It is required to configure the CFX File Transfer and, if not installed, the "CFX Publish Time Expression", "CFX Cutoff Time Expression" and "CFX File Transfer" fields will not be available. 

Sparkplug

Advanced



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.

Opcode Table support is now automatically enabled in release 4.0.15 and all 8 or 16 opcode tables (if using ROC or ROC_PLUS respectively) will show up in the drop down selector of the poll groups section without the need to create TLP Templates.


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:

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:

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.
