Fanuc Keep Relay Parameters Exclusive ((free))

to enable or disable specific machine options, logic flows, or hardware configurations without rewriting the PLC ladder. Key Characteristics of Exclusive Keep Relays Non-volatile Storage:

: Since specific settings are retained, there's less need for reconfiguration after power outages or system resets, thereby reducing downtime and increasing overall productivity. fanuc keep relay parameters exclusive

: Enter 1 to enable or 0 to disable the function. to enable or disable specific machine options, logic

A common factory mistake is using a "spare" Keep Relay for a new option without checking if the ladder logic already uses that bit elsewhere. Because K parameters are physical addresses, two different subroutines in the PMC cannot safely control the same bit unless explicitly designed for XOR logic. fanuc keep relay parameters exclusive
