4 Module Addressing
In This Chapter
Reading Discrete Inputs ........................................................................ 20
Writing Discrete Outputs........................................................................ 21
Each Flex or Integra module has 60 words of address space. 30 Input or Read
address and 30 Output or Write addresses. Data is mapped in two ways
Horizontal and Vertical.
With Horizontal addressing the adapter address the first input and output word
for each module incrementally. 40001 for module 0, 40002 for module 1 and so
on.
Vertical addressing increments the words for each module. For example, the
vertical read words for slot 0 start with 41001 and increment to 41015.
