I believe that indicates that you have an external alarm; look through your schematic for an external alarm input and then check the signal in check data that corresponds to the input in the schematic; I believe it should be high (on) under normal conditions and off (low) when it is in alarm state. No ladder on the 700L control.
Typically it means that a device such as a bar feeder or coolant pump, etc. is in a fault condition. Something other than the machine is wrong, thus, external device.
Experience is what you get just after you needed it.
