IndicatorConstants (GVL) ¶ This GVL defines the states of the two device LEDs according to CiA 303-3. These states are returned by GetCiAState and set by SetCiAState . The Error LED gc_usiERR_... (red) is represented by the lower 4 bit of CiA State, the RUN LED gc_usiRUN_... (green) by the higher 4 bit. InOut: Scope Name Type Initial Comment Constant gc_usiERR_OFF USINT 16#0 led off = no error gc_usiERR_ON USINT 16#1 led on = Bus off gc_usiERR_FLK USINT 16#2 flickering = LSS/Auto-bitrate detection gc_usiERR_BLK USINT 16#3 blinking = Invalid Configuration gc_usiERR_SFL USINT 16#4 single flash = Warning LIMIT reached gc_usiERR_DFL USINT 16#5 double flash = Error control event gc_usiERR_TFL USINT 16#6 triple flash = Sync error gc_usiERR_QFL USINT 16#7 quadruple flash = Event timer error gc_usiRUN_OFF USINT 16#0 led off = not running gc_usiRUN_ON USINT 16#10 led on = Operational gc_usiRUN_FLK USINT 16#20 flickering = LSS/Auto-bitrate detection gc_usiRUN_BLK USINT 16#30 blinking = Preoperational gc_usiRUN_SFL USINT 16#40 single flash = Stopped gc_usiRUN_DFL USINT 16#50 double flash = PROGRAM/Firmeware download gc_usiRUN_TFL USINT 16#60 triple flash = reserved gc_usiRUN_QFL USINT 16#70 quadruple flash = reserved
