Hi,
We are working on a project with Hot - Standby Saitel RTUs with isagraf for automation. I understand that
the Hot CPU is actively acquiring data with the field devices, while the Standby CPU gets its database updates from the active CPU via the redundancy link.
Can the internal variables defined in the isagraf program be transferred to the Standby RTU and the values of these variables retained if the Main CPU (i.e. Hot) fails and then switchover to the Standby CPU?

Hello.
The process described by you about how redundancy works is correct.
But initially only the signals added in coreDB are available to be shared between CPU´s.
So try to map it in coreDB if you can.
