Host Master Example
The Example
A hosted network utilizes an intelligent device, such as a personal computer, to act
as the network master station. Slave stations can be DCMs or DirectLOGIC PLCs
with built-in DirectNet ports. The host device initiates all communication requests
and the slaves respond to the requests for data. This example is not intended to
show you how to build DirectLink programs. You should review your programming
language manuals and Chapter 6 of this manual before you attempt to build your
own DirectLink programs.
This chapter provides an example that allows you to quickly and easily set up a
hosted network.
