RDA Functionality
The straton driver was extended with an RDA function. The RDA archiving requires a linear memory area in the PLC, which is realized with an array of the driver object type "RDA marker" in straton. This array must contain the appropriate RDA header + archive data. In the straton, only the Index [0] of this array may be activated and marked as an RDA variable. If the array Index [0] is set to 1, the corresponding values are read out from straton.
More information about the RDA archiving can be found in the online help of straton in the chapter Archiving.
Limitations
Arrays
Arrays are allowed; you can create them in straton. Please consider the different handling of the indices when the Array Start in the straton variable was set to 1.

If the array start in straton is set to 0, there will be no limitations. This option must be selected in the dialog during the creation of a variable in straton.
Structures
Structures are allowed. We recommend to create structure data types only in straton, even if they are only used locally in the PLC.
Versions
Due to performance issues, the straton Runtime Version 6.22 SP0 Build 2 needs the straton driver for the same or earlier zenon versions. Earlier straton Runtime versions still work with all straton drivers.
This driver supports the following functions:
