Bit 8 Reset Scanner Command
By complementing this bit, you reset the 1747-SCNR scanner (the reset occurs
when the SLC slot is de-activated).
It is important to note that if you do not disable the slot while the scanner is
resetting, the SLC module will fault with the error code nn57h (specifically, I/O
module in slot nn did not respond to a lock shared memory command in the
requested time limit) where nn is the slot number of the scanner. This is why the
reset bit change is not taken into account until the slot is disabled.
Bit 9 Disable ControlNet Scheduled Connections Command
When the bit value is 1, the 1747-SCNR scanner will close all scheduled
connections.
When the bit value is 0, the 1747-SCNR scanner will enable all scheduled
connections.
Bit 10 Scanner Mode Command
When the bit value is 0, the 1747-SCNR scanner is forced to Idle mode.
When the bit value is 1, the scanner’s mode will be determined by the mode of
the processor in slot 0.
Bit 11-15 Reserved
