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???
