8.2 Remanent variables
The controller makes available a maximum of 7120 bytes for storing remanent
variables (retain and persistent-retain variables). They are automatically shared
based on the variable declaration within the application.
The following sample combinations for assigning the memory are possible.
Retain variable Persistent-retain variable
7120 bytes 0 bytes (only if there is no persistent variable list)
0 bytes 7076 bytes (44 bytes for identification)
300 bytes 7076
-
300 bytes = 6776 bytes (44 bytes for identification)
x byte 7076
-
x bytes (44 bytes for identification)

Note
Error due to memory overflow.
Comply with maximum memory capacity for remanent variables: 7120 bytes.
