The following rung moves the block transfer read data into a “verified”
block transfer read file. The PLC program should only use data from the
“verified” read file.

To block transfer in a single direction, program a rung similar to the
corresponding block transfer rung shown above. Each block transfer read
instructions data should always be “verified” with a “file to file move” as
shown above.
IMPORTANT: If using a 1772-SD2 Remote I/O Scanner with a
PLC-2/30, you must use 1772-SD2 rev. 3 or later.
Use PLC-5 6200 software to configure a PLC-5/15 or 5/25 for
communication with remote I/O devices such as a PanelView terminal.
To use the following procedure your system must have this software:
PLC-5 6200 software release 2.2 or later
As well, you must have one of these PLC controllers:
PLC-5/15 Series B, rev. H or later
