The NTX-200 Substation Controller, smallest of our NTX Series modular substation system designs, incorporates complete substation management functionality. It also adds the ability to interface to a large amount of data from IEDs and to a small to medium amount of locally-wired data acquisition and control devices in the substation. The NTX-200 utilizes a client/server design. Throughout the NTX-200, servers (such as NTX Gateway to IEDs) produce data, and clients (such as the NTX gateway supplying the virtual databases to the master) receive data. It can also transmit many selected subsets of this data to one or more master stations in the master’s native protocol. Local I/O can also be configured in the three motherboard slots available.
In order to take maximum advantage of the client/server model, the NTX-200 uses a distributed processing architecture. Multiple high-performance ARM9E (Advanced RISC Machine) 32–bit microprocessors, each programmed to support specific functions, are linked together using a peer–to–peer type network. The ARM9E microprocessor-controlled high-capacity serial and Ethernet gateways make the NTX-200 an ideal, low–cost substation solution for data concentrator and protocol converter applications in small– to medium–sized substations.
- Distributed processing architecture featuring multiple high-performance, ARM9E 32–bit microprocessors with DSP extension in a client/server, peer–to–peer type LAN
- Embedded Linux operating system (not accessible by the user, for secure operating conditions)
- Legacy protocols from previous Connex NTU models will be supported based on demand
- Extended temperature range of –10° to 70°C (14° to 158°F)
- Multiple Virtual RTUTM database mapping
- Field programmable; remotely programmable via an Ethernet WAN/LAN
- Sequence–of–events reporting with 1ms resolution
- Built-in IRIG-B (unmodulated) Time Code Reader and GPS time reference (NMEA 0183) interface (optional external antenna required) or NTP time synchronization supported via the Ethernet Network
- Optional IEC 611131–compliant NTX Logic PLC that executes user–defined control and/or calculation algorithms
- Two USB channels: one for mini–USB to USB connections to the maintenance channel; one to support a thumb drive to update firmware and archive configuration files
- Multiple 10/100 BaseT Ethernet with DNP or Modbus RTU protocol over TCP/IP or UDP client, server or multiples of both, with a high quantity of IP connections available per port
- EURO Card format (3U x 42hp); mid-plane motherboard where the front module contains the majority of the Logic (Network CPU Node), and the rear module contains the corresponding terminations
- Multiple master/IED isolated communication serial interfaces (configurable per port for RS–232C, with or without flow-control, to external modems or fiber optics, or RS–485 for copper)
Application and expansion:
The NTX-200 can be used in a traditional centralized equipment rack– or wall–mounted cabinet. The three-slot I/O motherboard supports:
- up to three 16-point DC Analog Input Modules
- or up to three 32-point Digital Input Modules
- or up to three Bell 202 FSK Modems
- or any combination of these modules in the three slots.
The NTX-200 I/O is not expandable beyond the base three-slot I/O Motherboard. An NTX System Controller with termination provides a combination of router and dual-serial ports with an Ethernet Port, a 4 x 6 control relay driver matrix and DC Analog Output Channel functionality as the base communications, and an NTX internal network controller. Up to 24 external control relays can be equipped with both momentary (varying contact voltage/current ratings support) and latch relays and two external DC Analog Output channels.
The unit power supply and up to three additional NTX Quad-Serial with Ethernet port gateways can be incorporated in the card file mid-plane system motherboard—for a total of 14 isolated EIA561 RS-232/RS-485 RJ45 serial ports and 4 high-capacity 10/100 Ethernet ports. NTX Explorer software makes it easy to configure or expand the type and number of ports and protocols communicating with the master stations or IEDs, defining local I/O points, and/or other components. The NTX-200 can also serve as a remote Data Acquisition and Control node in a distributed substation system.
