Connection Statistics
The module maintains statistics for each scheduled connection. In the following table, O
represents the connection originator (ControlLogix) and T represents the connection
target (AN-X).
The statistics for each connection consists of 10 words of data. Only three words in the
ten word block are used.
Offset Description
0 Average time for last 32 updates
2 Minimum time since the connection statistics were reset
4 Maximum time since the connection statistics were last reset
The units for the times are 0.1 milliseconds. A value of 87 means 8.7 ms.
To map the statistics for a given connection, include a line with the keyword ConnStatsn,
where n is the connection number, from 0 to 15, in the input section of a connection.
Example:
,ConnStats2
Averages are calculated for the last 32 updates.
Connection 15 Mappings
When you autoconfigure the AN-X, it maps the following diagnostics to inputs on
connection 15.
Offset Length Description
0 2 Block error table
2 8 Connection diagnostics
10 10 Diagnostic counters
20 10 Connextion statistics for connection 0
We recommend that you use the same mappings and do not change them.
Resetting Connection Statistics
To reset the connection statistics, set bit 0 of output word 0 of connection 15. AN-X
resets the statistics on the transition from 0 to 1.
