I/O Assignments With A D4-430; I/O Assignments With A D4-440 - DirectLOGIC DL405 Manual

I/O Assignments You can only use one Interrupt module with the D4–430 CPU. Since the module
with a D4–430 must be placed in slot 0, the points used are X0 – X17. The following diagram shows
an example system with I/O assignments.
I/O Assignments Each Interrupt module consumes 16 input points. You can use two Interrupt modules
with a D4–440 with the D4–440 CPU. Since the modules must be placed in slot 0 and slot 1, the
points used are X0 – X17 for the first module, and X20–X37 for the second interrupt
module. If you only use one interrupt module, install it in slot 0. (You can install
another type of module in slot 1.) The following diagram shows an example system
with I/O assignments for a D4–440 with two Interrupt modules.
Interrupt Input modules must be placed
NOTE: The D4–440 supports manual I/O configuration. That is, you can manually
assign the I/O addresses in any order. If you use manual configuration, make sure
you must install the Interrupt modules (and use the addressing) as shown above.
Now that you understand the module placement and the I/O assignments, you're
ready to connect the field wiring.
