CONTROLLER STATE
This item sets the Operation Mode — Default, Run, or Stop — when the power is
ON.
The Controller State setting is valid only when the RUN/STOP switch on the back
of LT is set to Run. When the switch is set to Stop, the Operation Mode will
always be Stop, regardless of this setting’s value.
STOP ON MINOR FAULT
This item either stops the Controller or executes a logic program when a minor
fault occurs. If you wish operation to continue after a fault occurs, set this switch
to Continue; if you wish to stop operation, set it to Stop.
