Programming
Chapter 6
6–5
You can use the following ladder logic program with PLC-3 or PLC-3/10
processors. This program assumes that your application requires a single
BTR and BTW to pass data between the processor and the BASIC Module
(i.e. transfer of 64 words or less). If the transferred data exceeds 64 words
you must program multiple file to file moves to move different data sets to
and from the block-transfer files.
Refer to Figure 6.4 for the sample ladder logic and Figure 6.2 for the
corresponding BASIC program. You can use the BASIC program with any
processor. Values shown in the program are for demonstration purposes
only. Figure 6.5 is an actual sample program.
