Configure Block-Transfer Requests

To configure block-transfers to adapter-mode controller channel, use the adapter mode configuration screen in your programming software.

1.Define the BTW control and BTR control files you need. These control files must already exist (appear on the memory map) or the edit will result in an error. Each control word must contain a unique block-transfer control address to properly transmit block-transfers.

A.Enter the block-transfer file number.

B.Enter the element number.

C.Record on paper the BT files you define. This will help when configuring the BT files through the data monitor.

2.Since the adapter-mode channel controls the location from which data is transferred as well as the amount of data, load data into the block-transfer files by using data monitor screen in your programming software.

A.Specify a BT control file you defined.

B.Enter the transfer length in .RLEN

C.Enter the file and element numbers from which the data is to be transferred in .FILE and .ELEM respectively.
