What protocols does SCADA Cloud support?

SCADA Cloud connects Modbus TCP/RTU, MQTT, and OPC UA devices. It is browser-based with no app to install, offers remote access from any device, multi-site dashboards and fleet management, a cloud historian with unlimited retention, and team access with role-based permissions. From $29/month with a 30-day free trial.

Is there a free trial of the SCADA software?

Yes — both products start with a 30-day free trial. SCADA Desktop has a free 30-day trial download for Windows 10/11, and SCADA Cloud has a 30-day free trial in the browser.

Q: Should I choose SCADA Desktop or SCADA Cloud?

Choose SCADA Desktop if you want a local Windows application, no recurring fee, local historian storage, and operation inside air-gapped or tightly controlled networks. Choose SCADA Cloud if you need remote access, multi-site dashboards, easier team sharing, and browser-based monitoring without maintaining a local SCADA server.

SCADA Desktop is the local Windows product for plant-floor HMI and historian work. SCADA Cloud is the browser-based product for remote dashboards, multi-site monitoring, and team access. Both connect to industrial devices through Modbus-based workflows.
