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).
Word 5 provides active device status for complementary 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 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.3).

IMPORTANT
When a primary device is inhibited, its
complementary device is also inhibited. A
complementary device cannot be exclusively
inhibited.
