I am looking for a low cost HMI with minimal features. Cost expectation: $200 to $500 for a 100-200 tags license.

The features I am looking for:
1. OPC interface for data acquistion is sufficient (no other drivers required)
2. Graphics
3. Trends
4. Alarms
5. OPC Server for exposing data to third party software.

 

Red Lion has a good range of units with all the features you require.

Hello,
You can try Plantvue which is matching your requests. It's a VERY low cost Scada software with a powerful HMI and archiving system.

Hope to talk to you soon.
