Information on the Selection of the Shared RAM Version
The shared RAM structure is updated and enhanced by Schleicher
from time to time. A version number is used to distinguish between the
individual versions. The version number is increased for large
changes to the shared RAM structure where a change of variable
addresses is required. For this reason, shared RAM versions with
different version numbers are incompatible. Compatibility is only
ensured for matching version numbers.
The latest shared RAM version must always be used. However, if the
controller has old operating software, the older shared RAM version
that is suitable must be used. The "XCx11xx Revision History"
document has information on which shared RAM version can be used
with which operating software version. The document is available on
the Schleicher website at
under "XCx
operating manuals" or can be supplied on request.
The version of the controller operating software can be displayed in
the Info dialog window (3) for the corresponding resource in the PLC
project (via (1)
