Using Modems that Support
DF1 Communication
Protocols
The types of modems that you can use with Logix controllers include
dial-up phone modems, leased-line modems, radio modems and line
drivers. For point-to-point full-duplex modem connections, use DF1
full-duplex protocol. For point-to-multipoint modem connections, use
DF1 half-duplex master and slave protocols. In this case, one (and
only one) of the other devices must be configured for DF1 half-duplex
master protocol.
