Logic4Controls operates the API layer for deployed control applications — from operator panels to scheduling services — providing database access, usage metrics, and license validation across Windows and Linux environments.
| Service | Function |
|---|---|
| Service Database Access | Control applications retrieve recipes, device mappings, and tenant configuration from the service database through authenticated, TLS-encrypted endpoints with per-deployment scoping. Responses are versioned; writes are idempotent, so panel software retries safely after power cycles. |
| Usage Metrics Collection | A batched metrics API receives application usage events and aggregates them into operational statistics for the deploying organization. Typical load: a few kilobytes per installation per day — compatible with metered industrial links. |
| License Validation | Signed license verification responses cover entitlements, expirations, seat limits, and offline grace periods for field deployments. Raw keys never traverse the network; every validation is written to an exportable audit log. |
| Step | Phase | Description |
|---|---|---|
| 01 | Commissioning | Installation presents its license credential; platform issues deployment identity and API tokens. |
| 02 | Configuration | Application pulls recipes and device mappings; subscribes to centrally managed updates. |
| 03 | Operation | Steady-state database access plus scheduled batched metrics uploads. |
| 04 | Attestation | Scheduled license re-validation; audit trail available for compliance export. |
Yes. All traffic is outbound HTTPS to a documented, fixed set of hostnames; a static IP option reduces the rule to a single entry.
Applications continue on cached configuration and the license grace window; metrics queue locally and flush when connectivity is restored.
The platform carries configuration records and usage counters for the software itself, keyed by deployment — not plant process data. See the Privacy Policy for the full inventory.
Only your organization. Data is tenant-scoped end to end and processed solely to provide the contracted service.
