3.11 Ethernet Interface Overview

CPU Module Datasheet: CPUE05
For public disclosure
CPUE05 has a built-in Ethernet interface that makes it possible to communicate on a
10BaseT network. Both half-duplex and full-duplex operation are supported. Using
10/100 hubs allows CPUE05 to communicate on a network containing 100Mb devices.

3.11.1 SRTP Server

CPUE05 supports up to eight simultaneous SRTP Server connections for use by other
devices on the Ethernet network, such as the PLC programmer, CIMPLICITY HMI,
SRTP channels for Series 90 PLCs, and Host Communications Toolkit applications. No
PLC programming is required for server operation.

3.11.2 Ethernet Global Data

CPUE05 supports up to 32 simultaneous Ethernet Global Data exchanges. 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 variables across all Ethernet Global Data exchanges, and supports selective
consumption of Ethernet Global Data exchanges. Refer to
about Ethernet Global Data.

3.11.3 Station Manager Functionality

CPUE05 has built-in Station Manager functionality. This permits on-line diagnostic and
supervisory access through either the Station Manager port or via the Ethernet network.
Station Manager services include:
• An interactive set of commands for interrogating and controlling the station.
• Unrestricted access to observe internal statistics, an exception log, and configuration
parameters.
• Password security for commands that change station parameters or operation.
Use of the Station Manager function requires a separate computer terminal or terminal
emulator.
Refer to the VersaMax PLC Ethernet Station Manager Manual (GFK-1876) for
information about Station Manager operation.
