Steps In the KEPServerEX IoT Gateway plug-in, add a new Agent, set Agent Type to 'REST Server', and assign the tags to read to that agent Configure the agent's Network Adapter and Port Number (the documented example uses port 39320) Leave 'Enable write endpoint' unchecked to keep the agent read-only; HTTPS with a self-signed certificate is enabled by default Browse configured tags with GET http://<host>:<port>/iotgateway/browse, which returns the tag list as a JSON array Read tag values with GET http://<host>:<port>/iotgateway/read?ids=Channel1.Device1.Tag1 (comma-separate multiple ids) Unless 'Allow anonymous login' is enabled, send valid credentials with each request via HTTP auth Known gotchas The read query param is 'ids' (plural) — calling ?id=<tag> silently returns an empty readResults array with HTTP 200 instead of an error CORS is disabled by default so browser-based clients get a 403 on the preflight OPTIONS request until origins are explicitly listed The write endpoint (POST /iotgateway/write) is a standard capability but writes affect live equipment — leave it disabled unless specifically needed
