Run
DR = 0
ROR = 1
Default values are set
automatically. Outputs reflect
those of the scanner output image.
ROR = X
DR = 0 Outputs are unchanged.
DR = 1 Outputs are turned OFF.
DR = 0
ROR = 1
Default values are set
automatically.
Outputs reflect those of the
scanner output image.
Example 2 - Once the SLC processor is in Run mode, the bits in the
Remote Output Reset word have no effect on the RIO link device’s
outputs. Setting the appropriate bits in the Device Reset Word to 1
instructs the RIO link device to reset its outputs.
Example 3 - When going from Run to Program mode, if both of the
appropriate bits in the Device Reset and Remote Output Reset words
are reset to 0 before leaving Run mode, the RIO link device is
instructed to decide whether to hold its last output state or to reset its
outputs.

Test
DR = 0 In this instance, the last
ROR = 0 state switch setting is
valid.
DR = X
ROR = 1 These two
combinations reset device outputs.
DR = 1
ROR = X
DR = 0 In this instance, the last
ROR = 0 state switch setting is
valid.
Once these outputs are reset, they
remain reset regardless of the DR
and ROR settings.
DR = X
ROR = 1 These two
combinations reset device
outputs.

These default values are set
automatically. Outputs reflect automatically. Outputs are reset,
those of the scanner output image. unless ROR is changed to 0 on the
first scan.
