Using duplex Ethernet Units and redundant communications lines increases
the reliability of the network. The communications lines use a primary line and
a secondary line, to which Ethernet Units are connected. Normally the pri-
mary communications line is used, but operation will switch to the secondary
communications line automatically if an error occurs in the primary communi-
cations line or the primary Ethernet Unit, thereby allowing continuous commu-
nications.
CPU Unit Ver. 1.1 or later and CX-Programmer Ver. 4.0 or higher. Duplex
operation of Ethernet Units for a Single CPU System is possible for any CS1D
CPU Unit for Single CPU Systems, but CX-Programmer Ver. 4.0 or higher is
required.
A more reliable system can be configured by expanding the Duplex CPU Sys-
tem.
• Duplex Ethernet Units do not require duplex programming considerations.
• Ethernet Units use 100Base-TX and support high-speed communica-
