M1 File Status Words 16 through 47 - indicate how many RIO
communication retries the scanner makes to each adapter on the RIO
link if communication problems occur. Each word (16-47) contains a
retry counter for each configured quarter logical rack (words 16-31
are for primary logical racks, 0-3, and 32-47 are for complementary
racks, 8-11). Retry counters are useful for troubleshooting
communication problems (such as electrical noise or poor
communication line connections) between the scanner and any
adapters. The scanner clears the retry counters when going from
Program to Run mode, Test to Run mode, and Program to Test mode.
Note that the display (in words M1:e.16 -31) of retry counters
corresponds to the bits set in the Primary Logical Device Address -
Word 1 of the G file. Likewise, the display (in words M1:e.32-47)
correspond to the bits set in the Complementary Logical Device
Address - Word 3 of the G file.

Important: Individual quarter logical racks within a device cannot
be faulted. Therefore, only the starting logical group of
the device needs to be monitored.
Important: Your SLC control program cannot initialize/clear retry
counters.
