Display Your file-to-file move instruction displays your setting as
follows:
File Data
POSITION Hex Binary
003 0008 00000000 000010000
2. Repeat step 2 of section titled “Changing the String Length.”
Results The read block transfer file displays the 15 data characters in
positions 003 thru 010 with the data left justified (Table 3.C).

The module placed the space (20) in position 010 because it left justified
the data.
Displaying Right Justified Data
In this demonstration, assume that your margin justification bit IW3(03)
had been reset for right justification (in data mode, only), and that
initialization words one and two are set as follows: IW1=0002 and
IW2=0015.
1. Use file-to-file move instruction to store data you want write block
transferred to your industrial terminal for display. Load your
file-to-file move instruction (rung 15) exactly as shown (Table 4.D)
starting in position 001. Use the procedure in section titled “Writing
Data to Your ASCII Device”, P. 1-14.
Procedure P3 Set your industrial terminal to PLCĆ2 mode
Procedure P5 Load data into the fileĆtoĆfile move instruction
