F0003:0000 is the address of the write block transfer data file. You want to
enter/examine word 1.
1. Press [SHIFT][MODE] to display your ladder diagram on the industrial
terminal.
2. Press DD,03:0[ENTER] to display the block transfer write file.
The industrial terminal screen should look like Figure B.2. Notice the
highlighted block of zeroes. This highlighted block is the cursor. It should be in
the same place as it appears in figure B.2. If it is not, you can move it to the
desired position with the cursor control keys. Once you have the highlighted
cursor in the right place, you can go on to step 3.
