TIP
All items are of the form
offset [optional], ItemKeyword
If you create the ControlLogix configuration automatically when you
autoconfigure the S908 network, these items are mapped by default to
ClxSlot 15.
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-X-MOD (Master) maintains the following diagnostic counters.
Counter Offset Description
TxCount 0 Transmitted network frames
RxGood 1 Received frames with good status
RxPrtcl 2 Received frames with a protocol error
RxNoise 3 Received frames with a noise error
RxTout 4 Receive timeout. Scanner sent a message to a
drop but did not receive a reply within the
timeout period
RxCrc 5 Received frames with a CRC error
RxOvr 6 Received frames too long
RxAbort 7 Received frames with an abort error
RxShort 8 Received frames too short
RxErrMask 9 Error mask for protocol errors
To map the diagnostic counters, include a line with the keyword
DiagCtrs in the input section of a connection. This maps all ten
diagnostic counters; they cannot be mapped individually.
Examples:
, DiagCtrs
10, DiagCtrs ; offset 10
