GE Fanuc IC600LX605

The GE Fanuc IC600LX605 is a Combined Memory module designed for the Series Six Plus CPU, integrating both Internal and Register memory alongside Logic or User memory. Available in six configurations, the module offers memory capacities ranging from 5K to 80K, all of which include parity memory. User programs are stored within the Logic memory, which can operate with mnemonic instructions, ladder diagram logic, or a combination of both. The Logic memory is available in varying sizes, specifically 4K, 8K, 16K, 32K, or 64K of 16-bit words. The IC600LX605 is equipped with a lithium-manganese dioxide battery that ensures memory retention during power failures; its placement allows for easy voltage level checks via a lens on the unit's faceplate. The module features two visible LEDs: the 'Battery' LED indicates battery status, with a steady light signifying sufficient charge, while a flashing light prompts an alarm for low charge; failure to replace the battery is critical as it can lead to data loss within 30 days of the LED flashing. Meanwhile, the 'Parity' LED alerts users to memory access errors that can halt CPU operation, displaying an error message on the Workmaster Computer upon failure. Installation of the Combined Memory module requires placement adjacent to the Arithmetic Control module within the CPU rack. It is essential to use an extraction or insertion tool for this process and securely fasten the faceplate using screws. Safety protocols for the lithium battery dictate not attempting to recharge it or short-circuiting its terminals; proper disposal is crucial to prevent potential hazards.
