PRODUCT OVERVIEW
The N-TRON
to solve the most demanding industrial communications
requirements while providing high throughput and minimum
downtime.
The 308TX provides eight RJ-45 auto sensing 10/100BaseTX
ports. All ports are full/half duplex capable, using "state of
the art" Ethernet switching technology. The 308TX autonegotiates the speed and flow control capabilities of all eight
port connections, and configures itself automatically.
TM
308TX Industrial Network Switch is designed
to a climate controlled environment. The 308TX has extended
operating environmental specifications to meet the harsh needs
of the industrial environment. For cost savings and
convenience the 308TX can be DIN-Rail mounted alongside
Ethernet I/O or other industrial equipment.
The unique compact size provides a smaller footprint,
conserving space in the most critical dimension. In addition,
as with other DIN-Rail devices, the 308TX can be panel
mounted.
Since the 308TX is auto sensing, there will be no need to
make extensive wiring changes if upgrades are made to the
host computers, plant systems, or Ethernet I/O modules. The
switching fabric simply scales up or down automatically to
match your specific network environment.
The 308TX supports up to 4,000 MAC addresses, thus
enabling these products to support extremely sophisticated and
complex network architectures.
The N-TRON 308TX is an ideal candidate for upgrading
existing hubs and repeaters to increase bandwidth and
determinism by virtually eliminating network collisions. The
product also keep the network affordable, while maintaining
the plug & play simplicity of the unmanaged hub.
The 308TX can simplify plant wiring by eliminating the need
to bring data acquisition and control network connections back
T o increase reliability , the 308TX contains redundant power
inputs. LED's are provided to display the link status and
activity of each port, as well as power on/off status.
N-VIEW OPC PORT MONITORING (With -N Option Only)
The N-TRON N-View OLE for Process Control (OPC) Server
Software can be combined with popular HMI software
packages to add network traffic monitoring, trending and
alarming to any application using N-TRON switches
configured with the N-V iew option. N-TRON's N-View OPC
Server collects 41 different traffic variables per port and 5
system level variables per switch. This information can
provide a complete overview of the network load, service
quality, and packet traffic. OPC client software can use
N-View OPC Server data to resolve network problems quickly
and improve system reliability.
