Dear AVEVA Support Team,
I hope you are doing well.
We are currently working on a customer project that involves the AVEVA InTouch 2020 HMI platform. The customer has an existing 1,000-tag runtime license without I/O, which they are using for internal scripting and memory tags. Now, they want to bring in data from a weighing scale via OPC (connected over RS232), which would require real-time I/O tags.
To avoid upgrading the full license, we are considering purchasing an additional 500-tag InTouch runtime license with I/O.
We would like to clarify the following:
-
Can both licenses (1,000-tag without I/O and 500-tag with I/O) be installed and used on the same PC?
-
Will InTouch runtime detect and use the smaller I/O license for PLC/OPC tags, while the rest of the application continues to use memory/script tags under the larger no-I/O license?
-
Or, does the system only support a single active license per machine (in which case the license with the higher tag count would override the smaller one, even if it has no I/O capability)?
Understanding this will help us recommend the correct licensing path to our customer—whether to upgrade the existing license or deploy I/O functionality on a separate system.
We would appreciate your official clarification or documentation, if available.
Thank you for your support.
