Configuring RSLinx Classic Software for DF1
Half-Duplex Communications
Chapter Objectives This chapter provides a reference while configuring Rockwell
Software RSLinx Classic communication server software as a DF1
half-duplex polling master station or a DF1 half-duplex slave station.
RSLinx Classic is the communications driver for other Windows-based
Rockwell Software products, such as RSView32, which is an operator
interface package, and RSLogix 500, which is an SLC programming
package. Under Windows 98, Windows 2000, Windows XP, or
Windows NT, these software packages can all be run on the same PC,
which means one PC can function as SCADA master, operator
interface, and programming terminal. The Gateway version of RSLinx
Classic also adds the capability of allowing other PCs, also running
RSLinx Classic and connected to the SCADA master PC via local area
or wide area Ethernet, to have the same access to the telemetry
network as the SCADA master PC.
Configuring RSLinx Classic
Version 2.x as a Master
Station Figure 9.1 through Figure 9.8 show sample screens for configuring the
RSLinx Classic DF1 half-duplex polling master communications driver.
Some things to note in this example configuration are:
•
RTS control (hardware handshaking) is only available under
Windows NT. If the master modem requires RTS/CTS or
hardware handshaking, RSLinx Classic must be run on a
Windows NT personal computer.
•
The Modem Configuration option should be left as ‘No Modems’
unless the telemetry network consists of dial-up telephone
modems.

polling master configuration parameters, see the RSLinx Classic online
help.
