Willowglen Remote Terminal Units

1. 6000 Series RTU

When you need a robust and compact solution, the 6000 Series RTU is your choice. It is designed for plate-mounting, with I/O cards added on as required. Perfectly scalable for small to medium-sized systems, it can be equipped with multiple video ports for camera inputs. The RTU is able to transmit telemetry, video and audio data over the same communication channel.

2. 7000 Series RTU

The 7000 Series RTU consists of modular, high density I/O cards installed directly into a rack-mounted chassis. This series is excellent for large systems, capable of handling thousands of I/O points while conserving rack space. Multiple video ports for camera inputs are a standard provision. As with the 6000 Series RTU, telemetry, video and audio data are transmitted over the same communication channel. High-speed communications are facilitated by its built-in 10/100 Mbps Ethernet interface.

The 7000 Series RTU allows real-time viewing of multiple video images and remote video camera control. In addition, video images can be continuously stored on a local storage drive for later historical retrieval and viewing. To guarantee optimum RTU performance, various built-in integrated self-diagnostic functions as mentioned in the 6000 Series are also included. If reliability is your concern, we've got the solution. Redundant processor capability and the ability to hot-swap any card guarantees that your system runs without interruption. Maintenance work can be done with absolute convenience.

8000 Series Communication Controller

Imagine having a system with thousands of RTUs. Now imagine that each RTU needs a common transmission medium to communicate with the Master Station. This is where the Willowglen 8000 Series Communication Controller steps in to organize and simplify. Up to 128 communication ports consisting of modems, RS-232 ports and/or RS- 485 ports can be installed in a Communication Controller. For larger systems, multiple units of Communication Controllers can be used.

This series utilizes an industry standard high-speed bus, providing an open-system architecture. Redundant processor and power supply capabilities translate to unprecedented reliability. It can also act as a server with optional modules for Ethernet and SVGA connections, and modules that feature SCSI and serial interfaces. High-speed wide area networking? You've found it here.

RS485-to-RS485 Isolator & Repeater (ISO-485)

Optical isolation protects your equipment from dangerous ground loops, spikes and surges. Any of these misfortunes can scramble data or damage boards. Ground loops, spikes and surges can be stopped by inserting an optical isolation component in the data line. Willowglen ISO-485, which is a RS485 isolator/repeater, can be used for this purpose. ISO-485 optically isolates and protects equipment and also acts as a signal repeater to extend the range of RS-422/485 data lines. With using ISO-485, an existing RS485 system is expanded to greater than 32 unit-nodes limitation in the RS485 Standard.

All data lines, power and ground are isolated from one side of the ISO-485 to the other. It protects RS422 and RS485 equipment against 2500V RMS for one minute. ISO-485 also works on 2-wire or 4-wire systems. It can join 4-wire RS-422 with 2-wire RS-485 systems, simplifying the job and saving the cost of another converter. The ISO-485 uses terminal blocks on each side of the device. It supports Differential Transmit Data, Differential Receive Data, Signal Ground and Protective Ground. A power supply of 9 to 14VDC is needed to power up ISO-485 for normal operation.

SysLink SCADA Software

SysLink software is the answer to contemporary telemetry, video and audio requirements. Whether it's small scale or large, there is a SysLink solution to suit your needs. With SysLink, you obtain a single integrated view of your entire installation and video resources. Users can view and interact with the entire system using a highly configurable 3-D graphical interface and real-time video display of the remote site.

This software package is available in various platforms including Windows, X -Terminal and Sun Solaris. Workstations running SysLink are capable of being configured in a primary/backup mode for redundancy. Workstations of different architecture can also be seamlessly interconnected across the network. Multiple-monitor displays give your operator more room to view and execute

SysLink Benefits

SysLink Alarm Management

Willowglen’s SCADA system allows time stamping of alarms for detailed analysis. This system supports report-by-exception, which kicks into action during critical alarms. With mobile technology in full swing, SysLink incorporates automatic paging and SMS via standard GSM networks for immediate emergency notification.

SysLink Video
SysLink VIDEO is a long-term, low-maintenance digital video monitoring and storage solution. It is a cost-effective replacement for traditional analogue VCR systems. This solution offers sophisticated video storage and retrieval capabilities,

plus the advantage of real-time video streamed over your SCADA network. Advanced search capabilities mean significant reduction in time taken to find stored video compared to traditional searching through hours of VCR tapes. A user-friendly interface for remote camera pan, tilt and zoom control greatly boosts the security levels of your facility.

SysLink Graphical Programming Language (GPL)

An important feature of SysLink is the GPL facility which lets users construct control logic without worrying about the syntax of conventional programming. Development time is greatly reduced and maintenance work simplified. It adheres to the IEC61131-3 standard, supporting both Ladder Diagram and Structured Text languages. With advanced debugging features and a scheduler for event or time-triggered program execution, GPL makes programming a breeze for engineers. If programmes need to be changed or added at a later date, this is conveniently done at the Master Station. Unnecessary site visits become a thing of the past.
