To connect Ignition to an Allen-Bradley SLC (5/05 and 5/04) device

Go to the Configure section of the Gateway webpage.
Scroll down and select OPC-UA > Devices.
On the Devices page, find the orange arrow and click on Create new Device.
On the Add Device Step 1: Choose Type page, select Allen-Bradley SLC, and click Next.
Note that these PLCs do not have a native Ethernet connection, therefore another device like a Net ENI or an ENBT must be used for the connection.
On the New Device page, leave all the default values and type in the following fields:
Name: SLC
Hostname: type the IP address for the PLC, for example 10.20.4.56
Click Create New Device.
The Devices page is displayed showing the SLC device is added to Ignition. The Status will show as Disconnected and then Connected.
To see all the tags, go to OPC Connections > Quick Client in the Configure section, on the OPC Quick Client page expand the SLCfolder which contains all the folders with the individual tags.
