Block transfer operation with the PLC-3 processor uses one binary
file in a data table section for module location and other related data.
This is the block transfer control file. The block transfer data file
stores data that you want transferred to your module (during block
transfer write) or from your module (block transfer read). The
address of the block transfer data file is stored in the block transfer
control file. A sample program segment is shown in Figure 4.4 and
described in the following paragraphs.
The industrial terminal prompts you to create a control file when
either block transfer instruction is entered. The same block transfer
control file is used for both read and write instructions for your
module.
