Auto-Addressing
You can have the controller automatically assign address numbers
to drives that are connected and use the Drive Talk feature.
By default, auto-addressing is disabled. When enabled, an ACR
controller assigns addresses only to the Aries drives connected and
powered up.
For all Aries drives, the default address is zero—zero represents a
non-address to the drive. Therefore, the first acceptable address is
one.
The ACR controllers assigns each drive an address relative to the axis
to which the drive is connected. As the numbering for controller
axes begins with zero and the drives cannot accept an address of
zero, the addressing scheme is “off” by one. This is best illustrated
through an example.
For example, you have a eight axis ACR controller, and axes 0, 1, 4,
and 7 are connected to drives with the Drive Talk feature. The auto-
address sequence is as follows: the drive connected to axis 0 is
assigned address “1”; the drive connected to axis 1 is assigned
address “2”; the drive connected to axis 4 is assigned address “5”;
and the drive connected to axis 7 is assigned address “8”.
Enabling Auto-Addressing
► To enable auto-addressing, set the “Auto Address Request” bit
(bit index 0, Drive Talk Drive-Control Flags).
Drive Control Flags
The “Drive Talk Drive Control Flags” let you get and send
configuration data, set up the Aries error log, and retrieve status
data.
NOTE: All Drive Talk control bits are self-clearing. To perform an
action one time, set the control bit. When the bit is cleared,
the action is complete or the action has timed out.
Configuration
You can get and send the configuration data of an Aries drive. On
power up the controller does not contain any drive configuration
data. When you get drive configuration data, the controller stores it
in the “Drive Talk Parameters”.
