Device
(Note-1): Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion controller User's Manual" for the station number setting of safety signal
module.
(4) Parameters for safety observation function
(a) Safety signal comparison parameter
Set the parameter for safety signal.
Set the number of safety signal modules to be installed.
When "0" is set, the safety signal comparison function is not executed.
Set the allowance time for absorbing signal input time difference and signal
reading time difference for each CPU.
When "0" is set, a mismatch allowance time is 0.1[s].
Set the start device number of safety signal module to the both of PLC CPU and
Motion CPU.
• Match the start device number to I/O assignment by PLC parameter in PLC
CPU.
• Set the start device number using different I/O number of the other Motion
control modules and output device of limit output data in Motion CPU.
Match the station number setting
number.
This shared device area is used to exchange information for the safety
observation between the PLC CPU and Motion CPU.
Set this device within the range of a user setting area in each multiple CPU high-
speed transmission area.
