Import Allen-Bradley Database
The Import Allen-Bradley Database utility imports description files created with the
formerly Allen-Bradley APS software.
The APS database allows comments to be assigned either as Address Comments or
Instruction Comments. The utility imports both to the PLC-500 A.I. database. In
situations where an Address and an Instruction comment are assigned to the same data
table address, the Address Comment takes precedence and the Instruction Comment is
lost. The utility imports symbol names normally.
Note The import utility assigns rung comments imported from the APS software to the output
address for that rung. In cases where rungs with branched outputs have rung
comments assigned, the APS software uses the address of the top-most output in that
branch group, but the PLC-500 A.I. database uses the address of the bottom-most
output on a rung. The import routine will adjust rung comment assignments
automatically.
The same applies to instruction comments on multiple address instructions like ADD.
APS software uses the first address in the instruction, while PLC-500 A.I. uses the last
address in the instruction. The import routine will adjust instruction comment
assignments automatically.
To import the APS database correctly, APS’ .ACH file must be in the same directory as
APS’ .OP$ file. If the file exists, a prompt appears, giving you the option to copy the
.ACH file or to use the existing file. If you use the existing file, and rungs with
branched outputs have been modified significantly, the rung description assignments
may not be properly adjusted and will remain assigned to the original output address in
the APS database.
