The sequence programs for safety observation use the devices shown below.
Do not use the devices in the list for user program of PLC CPU.
Used for the safety signal
comparison and the speed
monitoring function
D8000 to D9499
M7000 to M8191
T1850 to T2047
Z15 to Z19
The device range (D/M/T) used by the sequence program for safety observation can
be changed to end device by setting "1" to SD980 of Motion CPU. Change SD980
before turning on the power again after the safety observation function parameter is
written in Motion CPU.
Used for the safety signal
comparison and the speed
monitoring function
1500 points of end of
device area
198 points of end of

Z15 to Z19
POINT
Even after power turns OFF, the setting value of SD980 is not erased because
SD980 is the latch device. However, this device is not included in ROM operating
data. When using SD980 in ROM operation, create the Motion SFC program that
sets the value of SD980.
