Publication 1747-UM013B-EN-P - January 2005
Scanner Configuration and Programming 4-17
M0 File - RIO Device Inhibit Control
M0 Words 8 through 11 - you use these words to command the
scanner to stop scanning logical racks 0, 1, 2, and 3. Bits 0 to 3 in each
word correspond to I/O group locations within logical racks 0, 1, 2,
and 3.
To stop scanning (inhibit) a device listed in the configuration (G) file,
set the bit corresponding to the starting group address of the device to
1. Setting bits that do not correspond to the device logical starting
group address will not inhibit the device. To resume scanning a
device, reset the bit (which corresponds to the starting group address
of the device) to 0.
Inhibiting a device does not affect the current settings of the Device
Fault Status (words 12 to 15 of the M1 file). Inhibited devices
eventually time out and either return to their last state or reset
(depending on the device’s last state setting).

Control functions (i.e., device inhibit, device reset,
and device output reset) are only selectable for the
primary device, but also apply to the complementary
device. Control functions for complementary devices
cannot be exclusively enabled.
