Sending data from one connection to another
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:
.png?alt=media&token=0ee66283-b8b2-4582-995c-5e7103ee157b)
Once the changes have been saved, if MQTT is connected, you should see the values being sent to MQTT:
