3–3Module Programming

6$-+%#5+0/ ;  '$36#3: 

Block transfer instructions with the PLC-3 processor use 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 (when

programming a block transfer write) or from your module (when

programming a block transfer read). The address of the block

transfer data files are stored in the block transfer control file.

The industrial terminal prompts you to create a control file when a

block transfer instruction is being programmed. The same block

transfer control file is used for both the read and write

instructions for your module. A different block transfer control file

is required for every module.

A sample program segment with block transfer instructions is

shown below.
