Tag Address Worksheet
This appendix contains a worksheet to help in planning an
application. Variables cannot be assigned to memory addresses that
overlap, and the only way to make sure they do not overlap is to
write them all down.
Make copies as needed and use them to enter addresses for each tag
in the application. Depending on what your application requires, you
may need one or more worksheets for each of the following:
• RSĆ232
•
Discrete I/O
• Block Transfer Read
•
Block Transfer Write
Or you may prefer to have a separate worksheet for each block
transfer (maximum of 10).
Note: If the application requires block transfer, be sure to mark off
the Status and Control bytes on the Discrete I/O worksheet(s). See
Page5–17.
In the Worksheet:
Each row represents one word of memory.
A signed or unsigned integer or a BCD type variable must be
assigned to one word.
Bits may be assigned to any available bit address.
