Overview
The DL405 offers full-size remote I/O.
The goal of remote I/O is to reduce wiring
costs, by allowing I/O points to be located
near the devices they are controlling. The
chart at the bottom of this page shows the
capacity for each CPU. The D4-450 has
the D4-RM functionality built into the
25-pin port directly on the CPU.
However, you can also choose to use the
D4-RM discussed here. Here’s how it
works: A special module called the Remote
Master is placed in the CPU base. This
Master module controls up to seven
Remote Slaves. The Remote Slaves are
connected to the Master in a daisy-chain
manner over a twisted pair communication cable (maximum length of 3300 feet
or 1000m). Each Remote Slave attaches to
a DL405 base (any size). Standard DL405

*max. of 2 D4-RM, 1 channel is via 25-pin CPU port
modules populate the remote bases.
You can assign normal input and output
addresses to the remote points, or you can
assign special remote I/O addresses. The
Remote Master sends the remote I/O
information to the CPU. The communication between the Remote Master and
the CPU is asynchronous to the CPU
scan. For this reason, remote I/O applications should be limited to those that do
not require the remote I/O points to be
updated with every CPU scan.

I/O Addresses Used
I/O modules in slave bases do not automatically consume any standard input and output
points. They consume remote I/O points at a rate equal to the number of I/O points in
each base. However, you can choose to use standard I/O addresses as an option
