Calculation of the storage space
The available 128 KB (131,072 bytes) of memory are subdivided as follows:
- 1280 bytes for the cyclic data
- 2000 bytes for internal administration
- x bytes as defined by the user for the acyclic data in the following
- y bytes: a shadow buffer as large as the largest memory object is kept on standby in the background.
Example: the acyclic memory objects Obj1, Obj2 and Obj3 are defined with 1,000, 3,000 and 7,000 bytes respectively --> x = 11,000 bytes and y = 7,000 bytes. Thus 113,072 bytes of storage space remain.
