Exclusively used for PMC management software data and should not be used for custom machine sequences unless specified by Fanuc.

The primary "exclusive" role of keep relays is to act as software-driven switches that bridge the gap between fixed CNC parameters and the machine tool builder's (MTB) custom ladder logic. Move the cursor to the specific bit and

Fanuc keep relay parameters, denoted by the address, are non-volatile memory bits used within the Programmable Machine Controller (PMC) to manage machine-specific logic and system configurations. Unlike standard internal relays (R) that reset when power is lost, keep relays retain their state (0 or 1) even after a machine shutdown, making them essential for persistent settings like tool change flags, interlocks, and optional hardware toggles.
