Program the Transfer of the Configuration Word
Program the transfer of the configuration word (from previous section) to the
module:
1. Using the memory map function, create integer file N10. Integer file N10
should contain one element for each channel used. For this example, we
used N10:0.
2. Enter configuration parameters for channel 0 (from previous section) into
N10:0. In this example, all the bits of N10:0 are zero except for the channel
enable bit (N10:0/11).
3. Program a ladder logic instruction to copy the contents of N10:0 to output
word O:1.0.
TIP
For more detailed information on these procedures, refer to
Chapter 7 (Ladder Programming Examples) and Chapter 9
(Application Programming Examples) of the user manual.
Dest # O:1.0
Length 1
On power up, the first pass bit (S:1/15)
is set for one scan, enabling the COPY
instruction to transfer the configuration
word to the processor's output image
table. From there it is transferred to the
module in the processor's I/O scan.
