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 Statu
s (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).
