Fiber-optic based serial communication card
The Fiber-Optic based serial communication card (Figure31)
offers means of establishing asynchronous (RS-232 like)
digital communications through multi-mode fiber media.
The use of the fiber-optic based serial communication
card accessory can enhance communication reliability,
and provides excellent electrical isolation thus protecting
transmitted data from extraneous electrical interference.
A pair of industry standard ST type fiber-optic connectors
are mounted on the back of the board enabling customer
connection to a digital communication system using fiber-
optic cables (customer-supplied).
The fiber-optic link has separate receive (RX) and transmit
(TX) ports operating at 820nm. Typical transmission distance
is 2000m with 62.5/125µm multi-mode fiber. Consult your
Eaton representative for availability of long haul solutions.
Link communication speed is controlled through software
and can be set at: 1200, 2400, 4800, 9600, 19.2k, and
38.4k. Modbus can also be set at 57.6k.
Digital communications must be programmed to ensure
proper operation of the serial fiber-optic accessory. Refer to
Service Information S280-104-2 Form 4D Microprocessor-
Based Recloser Control Programming Guide and S280-
104-3 Form 4D Control Communications Information for
additional information.
The fiber-optic based serial accessory includes TX and
RX indicating LEDs for verifying communications along
with an echo/non-echo switch for supporting ring/star
fibertopologies.
When operated in a ring configuration, the toggle switch
must be set in the ECHO position. In this mode, the
fiber-optic card will repeat (pass through) all messages
received on the RX fiber, and will respond to the Master
station by first echoing the incoming command and then
sending the response. This arrangement is best suited for
creation of low cost multi device fiber loops. For reliable
communications, the fiber loop system requires that all
devices in the loop remain powered at all times, thus
enabling unobstructed flow of information throughout the
loop. A 3.6 V battery can be connected to the card to keep
the loop active should the control lose power.
A more resilient system can be designed by using the
fiber-optic ports in a point-to-point or multiple point-to-point
(star) configuration. For this mode, the toggle switch must
be set in the NON-ECHO mode. The Form 4D pole-mount
control will respond to the Master station by sending a
response only (total separation of Receive and Transmit
fibers). Additional hardware (fiber-optic star coupler) is
required to support the multiple point-to-point device
configurations.
Ethernet communication cards
The Ethernet communication card accessories bring
Ethernet network connectivity to the Form 4D pole-mount
recloser control platform. Ethernet is highly flexible,
offering simultaneous support for multiple sessions, device
management (ProView NXG over TCP/IP) and SCADA
communications (DNP3 IP).
By natively supporting a set of widely accepted industry
standards (TCP/IP, UDP/IP, OSI) the Ethernet communication
accessory ensures seamless interoperability with other
network devices.
The Ethernet communication card accessory is offered in
5physical layer configurations (twisted pair and optical-fiber
options) as shown in Table 14.
