Table9.13 PLC system list (Continued)
Description
Set the number of empty slots on
the main base unit/extension
H
base unit.
Set the start No. of the interrupt
*4
counters.
H
Set the execution intervals of the
interrupt pointers (I28 to 31).
H
St the fixed scan interval, high-
H
speed I/O refresh setting and
H
high-speed buffer transfer
setting of the high-speed
H
interrupt pointer I49.
Select the service processing
execution method from the
followings.
• Execute the process as the
scan time proceeds
H
• Specify service process time
• Specify service process
execution counts
• Execute it while waiting for
constant scan setting
Sets the enabled contact device
No. at the time of backup of latch
H
data to the standard ROM.
Set whether an interrupt
program is executed at high
H
speed or not.
Set whether a CPU module
startup is synchronized with an
H
intelligent function module
startup.
Set whether the special relays/
special registers for MELSEC-A
series (SM1000/SD1000 to
H
SM1299/SD1299) will be used or
not.
* 1 : Cannot be set when the Redundant CPU and Universal model QCPU is used.
* 2 : High-speed interrupt setting can be made only when the High Performance model QCPU is used.
* 3 : Can be set only when the Universal model QCPU is used.
* 4 : The Universal model QCPU cannot set the head number of the interrupt counter.
