RIO Status Example
The following example illustrates an M1 status file example. It
shows a typical M1 file and the G file used to configure the scanner.
There are no inhibited devices specified in the M0 file (not shown).
Notice that:
M1:e.8 is an image of word 1 (primary/normal logical device
address) of the G file.
M1:e.3 is an image of word 3 (complementary logical device
address) of the G file.
M1:e.9 is an image/copy of word 2 (primary/normal logical
device size) of the G file.
M1:e.4 is an image/copy of word 4 (complementary logical
device size) of the G file.
The three quarter logical rack device located in logical rack 3
(M1:e.9/13) is not active. The fault is indicated by the Enabled
Device Fault status bit, bit 0, word 0 (M1:e.0/0).
The three quarter logical rack device located in logical rack 11
(M1:e.4/13) is not active. The fault is indicated by the Enabled
Device Fault status bit, bit 0, word 0 (M1:e.0/0).
Because the device at M1:e.8/13 is faulted, bit 13 of word 10
(M1:e.10/13) is 0. M1:e.15/1 through M1:e.15/3, which
correspond to M1:e.9/13 through M1:e.9/15 are also set to 1,
indicating a problem with the device in logical rack 3.
Because the device at M1:e.3/13 is faulted, bit 13 of word 5
(M1:e.5/13) is 0. M1:e.15/5 through M1:e.15/7, which
correspond to M1:e.4/13 through M1:e.4/15 are also set to 1,
indicating a problem with the device in logical rack 11.
