13.1.2 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.
13.1.3 SRTP Channels
SRTP Channels can be used by a Series 90-30 or Series 90-70 PLC to communicate with
CPUE05. The CPUE05 cannot initiate SRTP channels.
13.1.4 Attachment to the Ethernet LAN
The Ethernet port uses a twisted pair cable of up to 100 meters in length between each
node and a hub or repeater. Typical hubs or repeaters support 4 to 12 nodes connected in a
star wiring topology.
13.1.5 The Station Manager Software
CPUE05 provides built-in Station Manager support. It accommodates online diagnostic
and supervisory access through either the Station Manager port or via Ethernet. 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.
• Access to the Station Manager requires a user-provided computer terminal or
terminal emulator.
