Verified PurchaseWe've been using this driver for over 6 months in our oil & gas operations and it has been rock solid. The connectivity is stable, data accuracy is excellent, and the support team has been very responsive when we had questions during setup. Highly recommended for industrial applications.

Verified PurchaseOverall very satisfied with the driver. Had some initial configuration questions but support walked me through it. Once configured, it's been running smoothly for 3 months without issues. Would give 5 stars if the initial setup was more intuitive.
The demo is the full product once licensed. Once a client application connects to TOP Server, the runtime will operate for 2 hours at a time. At the end of the 2 hour demo period, the demo timer must be reset by restarting the TOP Server runtime service.
