Other Mappable Data
In addition to the I/O data, there are other items that can be mapped to
connection input data.
For all these items, you can assign an offset for the data within the
ControlLogix input data, or your can leave the offset blank and let AN-X
assign the offset automatically.
All items are of the form
offset [optional], ItemKeyword
Base Error Table
The base error table consists of 2 16-bit words.
The first word is the base error table. Bit 1 corresponds to base 1, bit 2
corresponds to base 2, and so on.
If a configured base is in error, the bit is 1. If a configured base is
responding correctly, the bit is 0. The bit is 0 for an unconfigured base.
The second word is the configuration mismatch table. Bit 1 corresponds
to base 1, bit 2 corresponds to base 2, and so on.
If a configured base returns a configuration error, the bit is 1. If there is
no error, the bit is 0. The bit is 0 for an unconfigured base.
To map the base error table, include a line with the keyword BaseErr.
Examples:
, BaseErr
10, BaseErr ; offset 10
TIP
Map the base error table to the first two words 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 monitors the base error table, it will see
the error bit as set.
Diagnostics
The AN-X-TI-MAS maintains a variety of diagnostic information about
the TI remote I/O network and the connections to the ControlLogix
processor.
To map the diagnostic counters, include a line with the keyword
AnxTiDiag in the input section of a connection. There are 240 words of
diagnostic data so the diagnostics are usually mapped to a separate
connection.
