DEVICE EXPLANATION
(4) Redundant CPU
* 1 : The time-out period of the internal timer is a default value. It can be changed in 0.5ms units within
the range 0.5ms to 1000ms in the PLC system setting of the PLC parameter dialog box.
* 2 : When an error interrupt with "I32 (error that stops operation)" occurs, the Redundant CPU stops
after performing the processing of I32 at error occurrence.
* 3 : I32 to 48 are disabled from execution (DI) when the system is powered on/the Redundant CPU is
reset.
When using interrupt pointers I32 to 48, execute the IMASK instruction to enable interrupts.
Refer to the following manual for the IMASK instruction.
QCPU (Q Mode)/QnACPU Programming Manual (Common Instructions)
* 4 : To use the intelligent function module for interrupt, the intelligent function module setting (interrupt
pointer setting) must be made in the PLC system setting of the PLC parameter dialog box. (Refer
to Section 6.23 for the interrupt from the intelligent function module.)
* 5 : Among I50 to 255, I50 has the highest priority (priority 2) and I255 has the lowest priority (priority
207).
