Logical Device Image Size Status
Word 9 – provides status/feedback of the logical device image size
you configure in word 2 of the G file (primary/normal devices). A
bit set to 1 shows the logical image size of each logical device.
Writing to word M1 file word 9 will not alter the contents of the G
file.

Active Device Status
Word 10 – provides active device status for primary/normal devices.
When a RIO device is communicating with the scanner the bit
corresponding to the device’s logical starting group is set to 1.
Devices that are inhibited in the M0 file (M0:e.8 – M0:e.11) are
represented by a 0. Unless devices are inhibited, not responding to
communications, or configured to an incorrect logical rack size, this
word is identical to the device configuration (M1:e.8).
