Controller type and command type for controller to read data from the drive.
An unused controller data table address containing the message instruction. This
address is the starting word of the destination file.
Number of elements (words) to be transferred. Each element size is a 16-bit integer.
Controller port to which the network is connected.
Specific starting address of the source file in the drive.
Enables communication to allow network messaging to be routed to the drive.
MultiHop Tab Example Value Description
To Address 10.91.100.79 IP address of the adapter connected to the drive.

Because the N-files used for the data transfer occupies two contiguous 16-bit words, the Size in Elements must always be set to 2 regardless of whether the
parameter being read is a 16-bit integer or a 32-bit integer.
