4.5 Resetting a Multiple CPU System
4.5 Resetting a Multiple CPU System
In a multiple CPU system, resetting the QCPU used as CPU No.1 resets all the modules (CPU modules, I/O modules,
and intelligent function modules) in the system.
(1) If a stop error exists any of the CPU modules in the multiple CPU system
Reset CPU No.1 or power off and on the multiple CPU system. The system cannot be restored by resetting any
CPU module other than CPU No.1.
Do not individually reset the CPU modules other than CPU No.1 in the multiple CPU system.
If reset, "MULTI CPU DOWN" (error code: 7000) will occur and the entire multiple CPU system stops.
Depending on the timing in which any of CPU modules other than CPU No.1 is reset, an error other than "MULTI
CPU DOWN" (error code: 7000) may occur, causing the other CPU modules to stop.
If any of CPU modules other than CPU No.1 is reset, "MULTI CPU DOWN" (error code: 7000) will occur
regardless of the "Operation Mode" setting in PLC parameter ("Multiple CPU Setting").
Slot number
If a CPU module other than CPU No.1
is reset in the multiple CPU system,
"MULTI CPU DOWN" occurs.
CPU No.1 resets the entire multiple CPU system.
