After a new Menta application was downloaded through Vista the IO modules indicated offline with a fast flash of the green indication light.
The Xenta controller is using too much workspace memory.
This can be seen from the memory allocation in Menta.
The TAC Menta Technical Manual describes work area as the following:
Work Area - Data created when executing the application program. For example, output status and time schedules.
Removing some of the time schedule holiday chart links will reduce the work area memory usage.
Once this memory is in a positive free figure, the application can be downloaded and the IO will return to normal operation.
