Note: the module health bits do not update if the drop is offline or if the connection to the
AN-X module is lost.
Quantum Module Status Data
Quantum modules each return a byte of module status data. Refer to the documentation
for each module for details on what the module status contains for a specific module.
There are 8 words of module status data for each rack, up to 32 words for each drop. The
status byte for slot 1 is found in the low byte of the first word, the status byte for slot 1 is
found in the high byte of the first word, and so on.
The table shows the locations of the Quantum module status byte for each possible
location. For example, the byte for rack 3 slot 7 is found at offset 19, low byte.

To map the module status data for a given Quantum drop, include a line with the keyword
dnModSts, where n is the drop number, from 1 to 32, and the length of the module status
data, in 16-bit words, in the input section of a connection.
The length must be large enough to include all modules in the configuration. For
example, if the last module is in rack 1 slot 3, the size must be at least 2.
If the length is omitted, AN-X uses a default length of 10. If a length of 10 is not large
enough to include all modules in the drop, AN-X generates an error when you download
the configuratuion to the AN-X.
If you omit the offset, the line must start with a comma.
Examples:
,d4ModSts,17
30, d4ModSts ; offset 30
Connection Statistics
The module maintains statistics for each exclusive owner scheduled connection. In the
following table, O represents the connection originator (ControlLogix) and T represents
the connection target (AN-X).
There are 10 words of connection statistics data for each connection, of which three are
used.
