If you create the ControlLogix configuration automatically when you autoconfigure the
S908 network, these items are mapped by default to ClxSlot 15 and below.
TIP
If you map the diagnostic data to a separate connection, use a long RPI
to reduce the Ethernet traffic, since the diagnostics do not need to be
updated as frequently as I/O data.
Diagnostic Counters
The AN-X2-MOD-MON maintains the following diagnostic counters.
Offset
Description
0
Received frames with good status
1
Input frame length mismatch
2
Output frame length mismatch
3
Received fram drop number mismatch
4
Received frames with a noise error
5
Timeout errors
6
Received frames with a CRC error
7
Received frames too long
8
Received frames with an abort error
9
Received frames too short
10
Error mask for protocol errors
11
Protocol error mask
To map the diagnostic counters, include a line with the keyword DiagCtrs in the input
section of a connection. This maps all the diagnostic counters; they cannot be mapped
individually.
If you omit the offset, the line must start with a comma.
Examples:
,DiagCtrs
10, DiagCtrs ; offset 10
To clear the diagnostic counters set bit 0 in word 0 of the output data for connection 15.
This clears the diagnostic counters and the connection statistics.
You can also clear the diagnostic counters and connection statistics separately from the
web interface.
