Internal Library Addressing Scheme
C-6 StorageTek SL8500 User's Guide
■
Column : The CAP magazines occupy the last three columns in the library. If the
library has one SEM, there are 19 customer accessible column. Therefore, the CAP
magazines would be in column 20, 21, and 22.
■
Side : Always a value of 1.
Example
For firmware address 1, 3, 22, 2, 10: The library value is 1. The rail is the third from the
top (3). The library contains one SEM (19 customer accessible columns, so column 22 is
the outer-most column). The CAP is on the left side (2). The slot is the 10th in the CAP
magazine.
PTP Internal Addressing
■
Rail : The value (1 to 4) refers to the rail adjacent to the PTP.
■
Column : Right PTP = column value of +6, left PTP = column value of -6.
■
Side : The side value is always 1, because the PTPs are on the outer wall.
■
Row :
– When numbering the device, the row is 0.
– When numbering a specific slot, the row is the slot in the PTP (1 or 2).
Example
For firmware address 1, 2, -6, 1, 0 : The library value is 1. The PTP is the second rail
from the top (2). It is on the left side (column -6), outer wall (side 1), and the address is
referring to the device (0).
Elevator Internal Addressing
■
Rail : The value is always 0, since the elevators do not correspond to a specific rail.
■
Column : The number of customer accessible columns plus 2. In a library with no
SEMs, there are 11 customer accessible columns, therefore the elevator column
value is 13.
■
Side : The value is always 2 because the elevators are on the inner wall.
■
Row :
– When numbering the device, the row is 0.
– When numbering a specific slot, the row is the slot in the elevator (1-4).
Example
For firmware address 1, 0, 21, 2, 4 : The library value is 1. The elevators span all rails
(0). The library contains one SEM (19 customer accessible columns plus 2 = 21). The
elevator is on the inner wall (side 2), and the address is referring to the fourth slot in
the elevator.
Robot Internal Addressing
■
Rail : The value (1 to 4) refers to the rail the robot is on.
■
Column : The value is always 0.
■
Side :
– If there is only one robot per rail, the value is always 1.
