Compiler Error C0102 - Schneider Electric

Compiler Error C0102

Message

Out of retain memory: Variable ‘<variable name>’, <byte size> bytes.

Message Cause

More retain memory is used than available on the PLC. It is also possible that the retain memory is too fragmented, due to incremental builds.

Solution

Use ‘Clean’ to de-fragment the memory. This will force a reallocation of all the data by the next build.

Error Example

For M241:

PROGRAM POUVAR RETAIN  arr1 : ARRAY[1...21000] OF BYTE;END_VAR

EIO0000003933.00
