Pool Address Range

The pool address range locations are used to supply cartridges required for diagnostic

moves to and from the target address range. A pool address is also used in a get

operation if a target address does not contain a cartridge. There is no specified access

order within the pool address range. The pool address ranges does not include drive

locations.

Note –

The address ranges are in the Library, Module, Row, and Column format.

Note –

The pool address ranges cannot contain drive locations.

Move Access Order

Sequential Access Order

In a sequential access order diagnostic move, the HandBot performs a get operation

starting with the first location in the target address ranges and then continues visiting

the locations sequentially through the range until it completes the requested number of

moves.

Note –

If you choose not to move cartridges the get/put operations are not performed.

The HandBot just positions itself at the target and pool addresses.

Random Access Order

In a random access order diagnostic move, the HandBot randomly picks a location in

the target address range to get a cartridge. The HandBot can also visit the same location

in the in the target address range multiple times to get a cartridge. The random access

routine ends after the requested number of moves is complete.

If you choose not to move cartridges the get/put operations are not performed. The

HandBot just positions itself at the target and pool addresses.
