Introduction
The EISC-100T (EISC) configurable switch in the
family
provides capabilities beyond those of standard Plug and Play (PnP)
switches. Besides conventional features — auto-negotiation, 10/100
Mbps data rate, flow control, half- or full-duplex operation — the EISC
has advanced features such as VLAN, trunking, Quality of Service (QoS)
and a programmable fault relay that can be connected to a supervisory
system. Individual port parameters can be configured via a console port
attached to a Windo
based workstation. Port status can also be
monitored through the console port using the Modbus protocol, making it
easy to interface the EISC with supervisory control equipment. These
features make the EISC one of the most versatile of Industrial Ethernet
switches available.
Configuration is accomplished via a console port connected to a
Windows-based configuration program included with the product.
Modbus protocol and register information is also provided so the switch
can be configured or monitored by a Modbus master device. Each port
parameter (data rate, duplex and flow control) can be pre-set via the
console port or set automatically via auto-negotiation. And a unique feature
displays the status (integrity) of the cable attached to any each port.
Each port automatically optimizes its data rate to 10 Mbps or 100 Mbps
— but data rate and duplex settings can be specified, if desired.
Each port negotiates flow control, but control can be disabled for
individual ports. The PAUSE function is supported for full-duplex links.
The backpressure scheme is used for half-duplex segments.
The EISC can be powered from wide-range, low-voltage
AC or DC sources and has provisions for either DIN-rail
or panel mounting.
