Product Description:
The 2ME915.90-1 interface module is produced by B & R Automation for the System 2010 Controllers series. As an expansion board that holds non-volatile program memory and power-loss buffering, it links application code to the CPU modules CP10x, CP2x0, or MP100 and keeps the control program available after shutdowns. Within an industrial automation rack, it provides the persistent storage and short-term energy reserve required for coordinated motion, sequencing, and data handling tasks executed by the overall controller.
The module reserves 2 MB FlashPROM for user program storage, and code is written directly into this memory through the internal FlashPROM programming function, so no external memory cards are needed. Volatile data such as variables and diagnostic logs occupy 2 MB SRAM, which is retained only while the controller is powered. The module has a depth of 122 mm, a height of 103 mm, and a width of 32 mm, allowing multiple modules to sit side by side on the System 2010 backplane. An LED on the front face serves as the programming indicator, confirming write cycles and operating status, while a slide switch on the housing activates write protection to block unauthorized changes.
Installed batteries safeguard user data during power loss, and an unused battery maintains its charge for at least 2 years. The manufacturer recommends replacement after a maximum storage period of 3 years at 30 °C to support reliable takeover. For shorter interruptions, onboard capacitors hold the SRAM contents for at least 10 minutes without external power, giving time to restore supply. All runtime services, including memory management and diagnostic logging, run under the PCC-Software operating system, aligning the module’s resources with the deterministic needs of System 2010 applications.
