NTX-U57 ( TG5700 RTU and I/O Subsystem Upgrade Solution )

 


NTX-U57 Controller

The Advanced Control Systems (ACS) NTX-U57 is a cost effective and feature-rich upgrade solution for L&G/Siemens TG5700 RTU & I/O subsystems. The NTX-U57 replaces the original TG5700 Controller Card piggy-back mounted on the original Termination Card (for each I/O subsystem type other than SBO Control), eliminating the need to disturb or replace any of the existing fi eld wiring. For the utility, this means up to 60% cost savings over a traditional RTU replacement, since the work required to reproduce drawings, re-cable, and do extensive point checkout is vastly reduced. The original TG5700 Station Manager or Supervisor Module host can be replaced with a NTX series Substation Controller, or any substation system that supports DNP/IP. 

 

Features and benefits:

 

  • Powerful, open-system architecture based on ARM 9E 32–bit RISC processor and Linux OS
  • Can be integrated with the ACS NTX-200 series substation controllers as the Supervisor Module or Station Manager Controller host, or with another substation control platform
  • Plugs directly into existing termination cards - no need to touch the existing wiring
  • No changes to the existing SCADA system database are required when using the same master protocol
  • Replaces proprietary protocol between modules with DNP 3.0 – opening up the system for easy expansion
  • Dual Ethernet ports support DNP3, Modbus TCP/IP or UDP with up to 8 IP clients, servers or multiples of both; also functions as integrated 2-port integrated Ethernet switch • Large 14,000 point database capacity per module
  • Provides time synchronization via IRIG-B (un-modulated), GPS satellite clock, NTP or DNP3 protocol
  • Easily expandable by adding ACS I/O subsystems to an NTX series Supervisor Module or Station Manager Controller host, or by using ACS-produced replacement termination panels paired with additional NTX-U57 units
  • Easily confi gured using our intuitive, Windows-based NTX Explorer application
  • Achieve NERC CIP compliance with the use of built-in solutions

 

NTX-U57/D

NTXU57D
The NTX-U57/D upgrade module replaces the TG5700 Digital Input Logic module, which plugs directly into the original TG5700 termination card. All customer contact input wiring is untouched in the upgrade. Each NTX-U57/D upgrade supports 32 optically isolated Digital Inputs, confi gurable per point as: binary with time (SOE with 1mS resolution); binary without time (Status/Indication); or Form A or two consecutive-point Form C counters (Accumulators).Contact wetting voltage is the voltage supplied by the original TG5700 Termination Panel, or the 18-24 VDC Power Supply provided for the NTX-U57/D module. The NTX-U57/D Binary Input Subsystem scans the 32 inputs every millisecond. Contact bounce is fi ltered by using a configurable sliding software fi lter; a chatter fi lter may also be confi gured. Each binary input point with or without time may also be non-inverted, or inverted where useful for point state definitions.
 

NTX-U57/A

NTXU57D
The NTX-U57/A upgrade module replaces the TG5700 Analog Input Logic module and plugs directly into the original TG5700 Termination Card. All customer analog input Panel wiring is untouched in the upgrade. The NTX-U57/A supports 24 DC diff erential Analog Inputs, with scaling utilized from the existing TG5700 Termination Panel Base. The NTX-U57/A uses a fully bi-polar ± 10 VDC (+ 5 VDC scalable), 16–bit A/D converter, and the analog termination cards carry scaling resistors. With legacy master slave protocols that support only 12–bit numeric values, the NTX-200 series substation controller, or other substation system host, normally strips out the four least signifi - cant bits. All ACS emulations of legacy protocols allow you to determine which four bits of the IED-supplied 15-bits scaled into engineering units are removed, without touching the sign bit. 
 

NTX-U57/C

NTXU57D
The NTX-U57/C upgrade module for retrofit of the TG5700 combination I/O node logic module plugs directly into the original TG5700 Termination Panel. All customer digital and analog input and existing Interposing Control Relay Panel wiring are untouched in the upgrade. Each NTX-U57/C upgrade supports 8 optically isolated Digital Inputs, confi gurable per point as binary with time (SOE with 1mS resolution); binary without time (Status/ Indication); or Form A or two consecutive-point Form C counters (Accumulators). Contact wetting voltage will be the voltage supplied by the original TG5700 Termination Panel, or the 18-24 VDC Power Supply provided for the NTX-U57/C module. Six DC diff erential Analog Inputs are available, with scaling resistors utilized from the existing TG5700 Combo Node Termination Panel Base. Positive 2.5 VDC and zero analog Reference Points are also provided as the 7th and 8th analog points. A fully bi-polar ± 10 VDC (+5 VDC scalable), and a full 16-bit A/D converter is utilized. The NTX-U57/C upgrade module provides 4 on-board Trip/ Close Relay output pairs that are expandable, using up to 28 T/C external interposing control relay pairs. The NTXU57/ C supports assigning T/C contact momentary relay closure times, in 1-millisecond increments, for each relay via the DNP3 TCP/IP or UDP protocol network interface to an NTX-U57/C control interface.
 

NTX-U57/R

NTXU57D
The NTX-U57/R replacement in the ACS upgrade incorporates a Binary Output Controller with an RS485 serial interface to any NTX-U57 upgrade panel’s unused second TG5700 RS485 conductor. ACS or customer-supplied isolated 24 VDC power supply will provide each module with 24 VDC power that will utilize the original TG5700 daisychained power conductors. The existing TG5700 Control Relay Panel is removed and the ribbon cables are simply moved from the TG5700 Relay Output Controller to the 26-pin cable connectors on the NTX-U57/R replacement. The NTX-U57/R provides an optically isolated, high-current 8 x 8 driver matrix for addressing each group of 4 T/C (or Latch/Reset) relays on up to 8 TG5700 Control Relay Modules, for a maximum of 32 relay pairs per NTX-U57/R. The original addressing jumpers are re-used as binary addresses 0 through 15 to select which U57/R Controller is being addressed by the master. Up to 16 NTX-U57/R Relay Controllers can be supported with a maximum of 1024 relays per upgraded TG5700 system.
 

Replacement Boards

NTXU57D
ACS has also developed replacement TG5700 Analog, Digital and Combo Node termination boards. These replacement Termination boards can be purchased with our NTX-U57 upgrade I/O subassembly modules to expand an existing TG5700 I/O confi guration, or separately in case of a TG5700 Termination board failure. These modules are not intended to work with original TG5700 Logic boards, but with ACS Upgrade Logic boards only.
