Note 1: If a device fails while in the state of READY or DISABLE, the device failure is not recognized until the
control goes into the PRESTART state.
Note 2: There are restrictions when the control goes into the Disable state from the Running State. The device is
immediately turned OFF without a Stop Delay. When the disable turns OFF, the control changes to the Ready
state.
Note 3: ERR Off (device fail) is monitored in Failed state, only if a) failed input caused the failure, and b) Auto Reset
is enabled.
