Rockwell Automation 2705 REDIPANEL KEYPAD MODULE USER MANUAL - Manual (Page 53)

Chapter 7
Programming
7–15
In the programming example shown in Figure 7.7, you’ll notice the length
has been set for (12), 8 words for the block transfer utility functions and 4
words for the Keypad Modules configured for 1/2 rack. The DATA FILE for
the block transfer read instruction begins at N11:0. This means the addresses
in the ladder logic, for the keypad input, will begin with N11:8/00. The
DATA FILE for the block transfer write instruction begins at N12:0. This
means the addresses in the ladder logic, for the keypad output, will begin
with N12:8/00.
Programming Example
Figure 7.8 shows an example of what the instruction addresses for the
RediPANEL Keypad Module would look like in the ladder logic, given the
configuration shown in Figure 7.7. The first 8 words of files N11: and N12:
have been reserved for the sub I/O scanner utility words.
