This rung adds up to 0.13ms to the processor scan time so use it sparingly.
Locate it at the beginning of your ladder program. This logic is not
required for PLC-2 family remote systems or for any other processor
family.
This example is written for the following conditions (Figure 4.3).
The module resides in rack 1, module group 2, slot 0
8-word block transfer
BTR control address is
FB001:0000
BTR file address is FB002:0001
MVF source file A is FB002:0001
MVF destination file R is FB003:001
MVF counter address is C000l
MVF number of words moved is 8
MVF rate per scan is
all/scan
