Appendix C
Data Address: 0050/051
This is the first possible address in the timer/counter area of the data table.
Use the first available timer/counter address for your first block-transfer
module data address.
Module Address: 470
The module is located in rack 4, I/O group 7, slot 0. (Two-slot modules
are addressed as being in slot 0.)
Block Length: 00
Use the default value for the maximum number of words to read (two)
and write (20). Although both files appear to be 64 words long, only two
words are used for read operations and 20 words are used for write
operations. The remaining words are available for storage.
File: 2600/2700
This is the address of the first word of the read/write file.
Use a file-to-file move to buffer your read data. Use addresses 2500 and
2501 when making data comparisons.
Rung 4 is entered for display purposes only. You do not need this rung in
your program; it allows you to look at the read- and write-data files
simultaneously.
Figure C.2
shows example values entered in the read- and write-data files.
These values were chosen for a 0 to 359-count BCD encoder.
