Methods and arrangements for providing bi-directional control between data storage drives and automation controllers

摘要

An arrangement includes at least one data storage device (44), an automation controller (46), and an enhanced interface (50). The data storage device (44) is connected to a computer (22) and arranged to perform a plurality of operations in response to one or more commands received from the computer (22). The automation controller (46) is configured to physically provide the data storage device (44) with at least one data storage media (90). The enhanced interface (50) operatively couples the data storage device (44) with the automation controller (46), such that the data storage device (44) can be selectively controlled by the automation controller (46) and the automation controller (46) can be selectively controlled by the data storage device (44) depending on the received commands. The enhanced interface (50) includes a standard serial interface (30) and at least one additional line (92). The additional line (92) is configured to provide a directing signal from the data storage device (44) to the automation controller (46). This added capability allows for bi-directional control between the data storage device (44) and the automation controller (46). <IMAGE>
