SCADA System

The 2300R is a state-of-the-art, rack mount, multi-drop data mo-

dem designed to provide the user with trouble-free data transmis-

sion in both self-healing ring and Multidrop string configurations.

This 2-slot card modem has self-diagnostic capabilities that can

be monitored on a computer via the front-panel mounted RS-232

or USB ports. A front panel mounted RS-485 port is provided for

interconnecting the network diagnostics on two or more master

modems. The PC based Network Management system incorpo-

rates real time system diagnostics for monitoring various net-

work and modem parameters including, but not limited to: Optical

connectivity, Optical budgets, Power supply voltages, Individual

modem operating parameters, alarms & alarm history and network

BER. A GUI network representation monitors the fiber connectiv-

ity for other modems that are on the ring / string network. If a fiber

is broken an alarm activates, giving the user a visual representa-

tion of a broken fiber and its location in the network. Both primary

and redundant fiber rings are simultaneously monitored by the

network diagnostics. The 2300R product family combines so-

phisticated self-healing ring topology and computer based diag-

nostics to provide your network with round the clock monitoring.

The self-healing ring automatically detects faults and reroutes

communicationson the ringto keep yournetworkoperational while

the built in diagnostics reduces the time required by technicians to

analyze, locate and repair the fault.

The modems can be installed in a string or counter-rotating,

fault-tolerant ring network. The switch selectable feature allows

each modem to be set as a Master (primary or secondary) or

Slave. The Master modems are connected to the PC via the

RS-232 or USB ports. This modem interfaces with both additional

PX-2300R modems as well as Meridian’s PX-2300M, surface-

mount Multidrop modem. The 2300R can be installed in all of

Meridian’s card chassis, desk chassis and 19” racking frames.

These systems can be made a standalone system by using the

SR-1000/S, 2 slot desk / wall mount chassis (87VAC-264VAC)

1.0 INTRODUCTION

The Meridian Technologies’ series PX-2300 Multidrop Fiber Optic Data Modems are designed to accept

RS-232, RS-422, and 2 & 4-wire RS-485 signals and optically transmit them in simple string and ring

networks as well as in dual, counter-rotating, self-healing rings with dual masters for increased fault

protection and redundancy. Up to 99 modems can be connected in a single network to provide almost

unlimited connectivity. Applications include traffic signal control, industrial process controls, and SCADA

networks.

The PX-2300M is the stand-alone or surface mount model while the PX-2300R is the rack mount unit that

occupies two slots in a standard Meridian chassis.

The Meridian PX-2300 series modems are equipped with built-in self-diagnostics that monitor and report

the status of each of the modems on the network and the fiber itself. This feature is unique to the PX-

2300 modems and provides a significant advantage over competitive products. On the PX-2300M

(surface mount modem) local access to the diagnostic information is via a large, easy to read, LCD

display on the top of each modem.

The PX-2300 is also compatible with Meridian’s SpectraSmart™PC Diagnostic network management

system. SpectraSmart continuously monitors “real-time“ data for Meridian equipment to determine the

integrity and operational status of diagnostic-equipped fiber optic modems, optical interfaces, fiber, etc.

(See section 6.2 for more details on SpectraSmart). Remote access to SpectraSmart diagnostics is

available via an RS-232 interface to a computer. Access to the diagnostic information on the PX-2300R

is available via the USB or RS-232 interface to Meridian’s SpectraSmart software that resides on a

standard computer.

The modems regenerate fiber optic signals and provide greater system loss budgets (and increased

distance). Wide temperature operating range and isolated diagnostic RS-485 driver allow to use

modems in harsh environments where ground loops and EMI/RFI interference may occur

2.0 NETWORK CONFIGURATIONS

The PX-2300 modem is designed to connect central computers and controllers with multiple remote

workstation / terminal units through fiber optic cables. The Master modem receives asynchronous data

from the central computer or controller and transmits it over fiber optic cables to Slave modems at

distances up to 30 miles (50 km) between the modems – using singlemode fiber. The PX-2300 modem

supports RS-232 data with handshake, RS-485 data (2-wire or 4-wire) or RS-422 full duplex data at

communication speeds up to 115 Kbps.

PX –2300 modems can be configured to operate in the following ways:

Multi-drop (Bus or String): Typical configuration for multi-modem applications including traffic

controllers, railways & subways, and oil or gas pipelines where linear arrays of data communication

nodes are required. Data from host (Master) is transmitted to all remote modems or slaves. The remote

equipment addressed at the remote location will accept the data, perform the necessary function and

transmit its data back to the master via the other remote modems between itself and the master.

Figure 2-1 below illustrates a typical string or bus configuration using one master and a number of

remote or slave modems at various add/drop locations. Because of the dual optical paths, it is not

necessary that the master be located at one end of the string or bus. Utilizing both clockwise and

counter-clockwise optical paths allows slave modems to be placed on either side of the master providing

added logistical flexibility.

11/11/2006 4 Rev 2.0

Self-healing ring: This configuration is the most complex one and highlights the various features of

the PX-2300 modems. In such a network configuration, data is transmitted down both rings (one

clockwise and the other counter-clockwise). In addition to the user’s data, PX-2300 network and

diagnostic commands are transmitted on the fibers. These signals are used to monitor the integrity of the

fiber network and perform the necessary diagnostics and fail-safe network reconfiguration to ensure the

fail-safe operation of the PX-2300 network. The PX-2300 also supports dual master modems for even

greater protection and redundancy.

Figure 2-2 below illustrates how the PX-2300 modems can be configured in a SHR network. The head-

end computer or controller is connected to the modem configured as the master modem. Data from this

master is then transmitted in both directions around the ring and dropped off at each of the remote or

slave locations.

Since the customer’s data is asynchronous, and not guaranteed to be present at all times, Meridian uses

its proprietary network control/diagnostic signals to continuously monitor the network’s integrity in both

directions and provide network performance and fault location information back to the system controller.

The default transmit/receive direction for the data network’s data is in the clockwise direction (‘A’ ring). In

the event of a fiber break or modem failure, the modems automatically switch to the back up or counter-

clockwise rotating ‘B’ ring to detect the network’s data. Other SHR networks provide a simple local

contact closure to indicate or alarm that the network has failed or gone into the self-healing mode of

operation. Meridian’s PX2300 modems provide this same local contact closure for compatibility but also,

through the SpectraSmart network management system, provide both local and remote indication and

identification of the fault – a major technology breakthrough and significant cost advantage to network

management.

As shown above, the Meridian PX2300 series digital fiber optic data modems can be easily configured

into string or ring networks. Key factors in their networking and expansion capabilities include the ability

to drop, add or repeat channels at any modem without signal degradation. Commonly referred to as a “

counter – rotating “ ring, the self-healing ring (SHR) architecture allows easy network expansion up to 99

slave modems, add or drop channels at any modem on the network and provide signal path redundancy
