Aspentech Rate Limits

AspenTech APIs (notably Inmation Web API and Simple Call Interface) run on customer-deployed Inmation servers. There are no platform-imposed per-second rate limits; throughput is bounded by the customer's deployment topology, server sizing, and tag/process volume. AspenTech does not publish a public rate-limit table.

Limits

Inmation Web API (deployment-bound) server
varies
bounded by customer Inmation server sizing and configuration
Throughput limited by server CPU, tag count, and concurrent WebSocket connections rather than a published per-second cap.

Policies

Operator-Configured
Limits are tuned by the deploying operator on the Inmation core server; no AspenTech platform-level public throttle is published.
Backoff Strategy
Clients should implement exponential backoff with jitter on 429 / 503 from the Inmation Web API.
