Fault Variables
In the Tag Explorer select General System Variables, then select
RIO_fault_code in the Tag Window.
When RIO_fault_code
≥
4, RIO_status = 1 (OfFLine), the LED on the
RIO option is
OFF
, and Global_fault = 10 (RIO Fault). The different types
of RIO faults are explained following.
Initialization Failure
An RIO initialization failure fault (RIO_fault_codem = 9) indicates that
the RIO option failed to pass its power-up diagnostics. When
RIO_fault_code = 9, RIO_status = 1 (Offline), the LED on the RIO option
is OFF, and Global_fault = 10 (RIO Fault).
Setup Failure
An RIO setup failure fault (RIO_fault_code = 7 or 8) indicates that the
RIO option could not be set up by the motion controller as configured.
When RIO_fault_code = 7 or 8, RIO_status = 1 (Offline), the LED on the
RIO option is OFF, and Global_fault = 10 (RIO Fault). Check that the
RIO setup data for the adapter or scanner is correct.
