The resulting device mapping will appear in the lower panel:
Slot 1
Double word 0
I = Input
In chapter 3 the 1756-DNB module was installed in slot 1 in the
ControlLogix chassis. In this example the inputs from the
RediSTATION are mapped to double word 0 for slot 1 as bits 0-7 of
the low word (L). Recall from chapter 2 that the START button is bit
1 and the STOP button is bit 0. Therefore, the addresses for the
RediSTATION inputs are:
START Local:1:I.Data[0].1
STOP Local:1:I.Data[0].0
The input from the photoeye is mapped to double word 0 for slot 1
as bits 8-15 of the low word. Recall from chapter 3 that the input bit
is bit 0. Therefore, the address of the photoeye input is:
Local:1:I.Data[0].8
3. Note the addresses assigned to the START and STOP buttons
and the photoeye in your system. You will use these addresses
in the example application program.
