For public disclosure
VersaMax CPU model IC200CPUE05 has a built-in Ethernet interface that makes it
possible to communicate on a 10BaseT network in either halfduplex or full-duplex mode.
Using 10/100 hubs allows CPUE05 to communicate on a network containing 100Mb
devices.

Use the Ethernet interface to:
Send and receive Ethernet Global Data.Ethernet Global Data can be used for
•
highly efficient periodic data transfer on the LAN.
Access data from CPUE05 using a Host computer. Computer applications
•
can access data from CPUE05 through its SRTP server capability.
• Communicate simultaneously to multiple devices. The multiplexing
capabilities of Ethernet interface, along with Ethernet network's high capacity, allow
CPUE05 to communicate with several other devices at the same time.
• Indirectly attach to other Local Area Networks and/or wide area
networks via third party IP routers. CPUE05 can communicate with remote
PLCs and other nodes via an IP Router.
• Communicate with remote computers via Serial Line Protocol (SLIP)
using modems and/or serial lines. Using third party SLIP devices, a remote
host computer can be attached to a TCP/IP network. Once attached, the serial
communications can be routed over the Ethernet interface to the CPUE05.
Maintain compatibility with other devices. CPUE05 is compatible with the GE
•
Series 90-30 Ethernet Interface, Series 90-30 CPU364 Embedded Ethernet Interface,
and Series 90-70 Ethernet Interface (Type 2). It is also compatible with GE
programming packages supporting TCP/IP Ethernet communications.

13.1.1 Ethernet Global Data

CPUE05 also supports up to 32 simultaneous Ethernet Global Data exchanges. Ethernet
Global Data exchanges are configured using the PLC programming software, then stored
to the PLC. Both Produced and Consumed exchanges may be configured. CPUE05
supports up to 1200 data ranges across all Ethernet Global Data exchanges, and can be
configured for selective consumption of Ethernet Global Data exchanges.
