Remark
Set the number of slots in the CPU base
or extension base.
Set the total number of Multiple CPUs
including PLC CPU(s).
Set the automatic refresh between CPUs
using Multiple CPU shared memory.
Set whether or not to stop the entire
system when a CPU stop error occurs in
each CPU.
Install the modules controlled by the self
CPU in the CPU base and/or extension
base(s).
Set detailed items for each module
controlled by the self CPU.
Set the operation cycle of motion control.
Set the condition in which the PLC ready
flag (M2000) turns on.
Set the bit device used for forced stop.
Set the latch range of device memory.
Set the installation position of the self
CPU in the CPU base.
Set the model name, axis No. and other
details for the servo amplifiers and
servomotors.
Set the high-speed read data. Refer to "
8.12 High-Speed Reading of Specified
Data " for the high-speed read function.
Set whether or not to use an external
battery. If the power supply is down for
one month or longer, data must be
backed up with an external battery. Refer
to "Q173CPU(N)/Q172CPU(N) User's
Manual" for external battery.
