Transfer Data Between Connections

In this example we'll configure Clarity Gateway to send values from an EtherNet/IP connection to MQTT. To do so we have to use use System Tags as an intermediary. The EtherNet/IP connection will transfer the values from EtherNet/IP tags to the System Tags, and the MQTT connection will transfer the values from the System Tags to MQTT tags:

EtherNet/IP Tag	→ System Tag	→ MQTT Tag
CURING/HEATED_MIN_TEMP	→ Site 1/Heated Min Temp	→ heatedMinTemp
CURING/HEATED_MAX_TEMP	→ Site 1/Heated Max Temp	→ heatedMaxTemp

We'll assume an EtherNet/IP connection has been created and provides the tags CURING/HEATED_MIN_TEMP and CURING/HEATED_MAX_TEMP:

First we'll set the System Tag Prefix to Site 1/:

Then we'll click the checkboxes at the left to enable and change the System Tags for these channels to Site 1/Heated Max Temp and Site 1/Heated Min Temp:

Finally, click Save:

Once these changes have been saved, if EtherNet/IP is connected you should see the values getting routed to the system tags (you may need to change the search to see the channels again):

Next we'll assume an MQTT connection has been created. Navigate to it by clicking it in the sidebar:

In the Channels To MQTT table, make sure that Show All Tags is turned on:

Then if you search or scroll down you should be able to find the System Tags we're writing from EtherNet/IP (Site 1/Heated Min Temp and Site 1/Heated Max Temp):

Click the checkboxes at the left to enable these, then set the desired MQTT Tags (in this example, Heated Max Temp and Heated Min Temp):

Finally, click Save:

Once the changes have been saved, if MQTT is connected, you should see the values being sent to MQTT:
