Using the Data Highway Plus Network
This chapter describes the basics of Data Highway Plus (DH+) and the
operation of a DH+ network.
What is Data
Highway
Plus?
On the most basic level, Data Highway Plus is a wire or cable and a
protocol that connects computers and peripheral devices so that they
can communicate. The wire used for a network is called the network
medium.
A DH+ link transfers data between ControlLogix controllers, PLCs,
SLCs, and other devices that use the DH+ network. These devices are
called stations. You can connect a maximum of 32 stations to a single
DH+ link.
