Block Transfer Examples for Earlier Processors

D-9

Directional Repeating Block Transfer Example

The following example shows a directional repeating block transfer.
This means that block transfer reads will be sent repeatedly, as fast as
possible. Use the same method for a BTW.

Rung 2:5
BLOCK TRANSFER READS WILL EXECUTE CONTINUOUSLY AS LONG AS THE BTR PRECONDITION
BIT IS TRUE.
