Typical OPC DA configuration file for EMS
Following is a typical lua script for an OPC DA Edge Thing. Since most functionality is built in, not a lot of configuration is needed.
host="localhost"

port=5222

jid="DAChannel@thingworx.com"

password="admin"
Where:
host="localhost" — Localhost is the Edge MicroServer location.
port=5222 — 5222 is the Edge MicroServer Default port.
jid="DAChannel@thingworx.com" — DAChannel@thingworx.com Matches name of the Channel at the Server.
password="admin" — The password for the user selected in the EdgeDatabaseThing password can be encrypted.
