Note: I/O Address Designation
•
The CPU assigns addresses in sequential order to the I/O modules on the backplane,
starting at address 0.
•
The CPU automatically determines whether the register data from the modules is of type
input or output.
• The 16-point I/O modules use one word of register memory. The 32-point I/O modules
require 2 words of register memory. Analog and Intelligent function modules can require
from 1 to 4 words of register memory.
•
The combination I/O module consisting of both inputs and outputs is separated into a one
word input and a one word output. On a 16 point mixed I/O module, the eight input or
output points will use up the lower 8 bits (00 to 07) of their respective words.
•
When a slot is empty, a blank (D320BNK300) module can be installed. When addresses
are automatically assigned by the CPU, no address is assigned to a blank module.
