C - 6 RSLinx – Training Guide
Using LINX with the Emulator
The Emulator uses RSLinx or Wintelligent LINX as its driver or “link” to other software
packages such as RSView32 or RSTools HMI projects or RSLogix 500 or RSLogix 5
ladder logic software.
The emulator functions much the same as a real PLC. Under Windows, it runs separately,
and does it’s job (pretending to be a PLC) without being “aware” of what other software
programs are “using” it. And from their perspective, other software packages such as
VIEW or RSLogix aren’t really “aware” that they are talking to an emulator rather than a
PLC-5.
Linx is always required.
This situation is brought about by means of LINX being the “middle man” for Rockwell
Software software under Windows, whether they are talking to a real PLC or an emulated
PLC. In other words, from RSLogix 500’s standpoint, it asks LINX to connect to a PLC -
it really doesn’t know or care if it’s a real PLC or an emulated PLC.

program is a
