AN-X2-GENI (AN-X-GENI/B) Page

TIP
Map the block error table to the beginning of input data of each
connection. If the connection to the AN-X module is lost, the
ControlLogix sets the first 2 words of the connection to FFFF
hexadecimal. If your program is monitoring the block error table, it will
see all the error bits as set.
Block Fault Table
A Genius block can generate fault messages for a variety of error conditions. If the
AN-X2-GENI receives a fault message from a Genius block, it sets the corresponding bit
in the block fault table.
The block fault table consists to 2 16-bit words, one bit per serial bus address. Bit 0 of
the first word corresponds to serial bus address 0, bit 1 corresponds to serial bus address
1, and so on.
To map the block fault table, include a line with the keyword BlockFlt in the input
section of a connection.
Example:
,BlockFlt
If the block fault bit is set for a block, use the web interface on the AN-X2-GENI to view
and clear the fault. Refer to page 45 for details.
Connection Diagnostics
The AN-X2-GENI maintains diagnostics related to the UDP traffic to and from the
module. They are mapped using the keyword ConnDiag.
Example:
, ConnDiag
They consist of:
Offset
Counter
0
UDP Tx count
1
UDP Rx count
2
UDP Eth Error, Ctr (lo) Typ (Hi)
3
UDP PrtErr, Ctr (Lo) Typ/Slt (Hi)
4
UDP Tx Busy
5
UDP Rx Busy
