Start/Stop Operation Using Stop Input and Reset Input
Any input terminal available on the SmartAXIS can be designated as a stop or reset input using the Function Area Settings. The
procedure for selecting stop and reset inputs is described "Stop Input and Reset Input" on page 5-4.
Note: When using a stop and/or reset input to start and stop operation, make sure that start control special internal relay M8000 is on. If M8000 is
off, the SmartAXIS does not start operation when the stop or reset input is turned off. M8000 is not turned on or off when the stop and/or reset
input is turned on or off.
When a stop or reset input is turned on during program operation, the SmartAXIS stops operation, and all outputs are turned off.
The reset input has priority over the stop input.
