the retain memory in AC500 (PM554 & 556)
H i to all
i have been using the AC500 PM554&556 . I know that these PLCs present about 1 KB for retain memory. but when i define a retain memory and after that i define a bool retain memory when i rebuild it,the CoDeSys says that out of retain memory!!!
anyone know what is the problem???

Hi
The description of your problem is not very clear, however I try to give you some indication ...as far as I know, the memory layout of AC500 CPU is in the following image
You need to assign the correct memory size of data of your variables
Hope this help you
