Program transfer and protection for LOGO! 0BA4+
The Siemens 6ED1056-5CA00-0BA0 is a Flash-EPROM memory card for the LOGO! controller family, designed to duplicate programs and apply know-how protection on LOGO! 0BA4 and later generations. This card stores the switching sequence and logic from the LOGO! CPU, allowing a user to copy the program to another unit or lock it against readback — a practical tool when deploying the same logic across multiple panels or protecting IP in a commissioned installation.
Flash-EPROM storage and lifecycle
The memory type is Flash-EPROM, meaning the stored program is retained without battery backup and can be rewritten as needed for field updates or cloning.
