(1) After checking that External power supply status is on, turn on Safety output control initial processing request flag (SA\Y2E) so that Safety output control
initial processing completion flag (SA\X2F) turns on.
(2) After checking that Safety output control initial processing completion flag (SA\X2F) is on, turn off Safety output control initial processing request flag
(SA\Y2E) so that Safety output control initial processing completion flag (SA\X2F) turns off.
(3) After checking that Safety output control initial processing completion flag (SA\X2F) is off, turn on Safety output control start flag (SA\Y2F) so that Safety
output control READY (SA\X2E) turns on.
(4) After checking that Safety output control READY (SA\X2E) is on, turn off Safety output control start flag (SA\Y2F).
(5) Safety output control READY (SA\X2E) turns on, and safety outputs and test pulse outputs start.
Controlled by the safety remote I/O module
Controlled by the program
*1 An external power supply voltage error has not occurred.
*2 An external power supply voltage error has occurred.
Setting method
To select what operation is to be performed at the detection of an external power supply voltage error, set the operation in
"Operation setting of external power supply voltage error detection" on the "Parameter Processing of Device Station" window
of the engineering tool.
For the procedure to display the "Parameter Processing of Device Station" window, refer to the following.
