Versatile Data Server (VDS) is Web-based HMI/data server software that adds advanced architecture to the conventional HMI/SCADA functionality.
VDS's graphic windows run on VDS Viewer (Java application), so just a personal computer and no special dedicated software can be used to access VDS running on site and grasp the site statuses and perform operations and monitoring anytime, anywhere.
Each client computer used to access VDS and perform operations is a thin client requiring no special dedicated software. The man-hours and cost needed for updating the operating system and dedicated software are thus greatly reduced, and the cost for purchase of HMIs is also cut because there's no need for special computers for process operations.
VDS can easily link a variety of equipment including FCN and FCJ autonomous controllers, various suppliers' programmable logic controllers, temperature controllers, and power monitors, on an integrated network. Whether for factory or process automation equipment, VDS can handle various applications for production lines and manufacturing processes.
By linking FCN and FCJ autonomous controllers featuring loop control and sequence control, a high-performance process control system can be built at low cost.
In addition to the graphic window presentation on a VDS Viewer, VDS also offers a host of functions to make operations easier.
VDS offers extensive graphic functions for building graphic windows that show the system at a glance, for efficient operation.
VDS's security functions can restrict access to writing data, running a program, and so on, to protect the system against unauthorized users. VDS also records a log of the actions taken at the system as a detailed audit trail. Even when accessing an on-site system via a VDS Viewer, users must enter their user name and password for authentication.
Process alarms and user-defined messages can be viewed on the alarm summary display and announced using sound output in different ways depending on their importance, making them easy for operators to identify. These messages can be analyzed later on the historical message file and on a printout.
A trend graph of acquired and saved data can be pasted to a desired position on a graphic window so that the progression of data over time can be grasped. Trend data saved in VDS can also be exported to a CSV format file for preparing reports and in-depth analyses.
To offer a concise environment for developing applications, maximize throughput and facilitate maintenance, VDS has a simple software structure and functions for managing users' own programs.
From the functions for communicating with I/O devices to those for transferring the data on graphic windows running on VDS Viewer, VDS consists of a simple, hierarchical structure of functions.
Functions for managing alarms and messages, which are crucial in equipment and process operation, and process management functions to run and quit various programs, can be developed effortlessly using standard tools. There is no need to develop management programs using Visual Basic or other programming languages.
Object-oriented engineering tools for all engineering tasks from defining I/O device connections and data acquisition specifications up to creation of graphic windows make application development that much more efficient.
Defining connections to I/O devices:
Simply select a proper driver for each I/O device to be connected and make basic communication settings such as an IP address. There's no need to write a troublesome communication program.
Defining data for operation and monitoring:
Simply define tags called control objects, set the method of acquiring their data (periodically, one-shot, etc.), and make auxiliary settings such as the scaling specifications. Control objects you defined can be grouped for reuse.
Graphic windows running on VDS Viewer can be created by simply pasting supplied graphic parts and specifying their actions.
Optional Test Package features useful functions for efficient debugging during system configuration, including:
VDS basic software is available in two versions. The full-time version has both development and runtime environments; the runtime version offers only the runtime environment. Use of the runtime version allows a cost-efficient system to be built.
|Basic software license||Full-time version||NT610FJ||Available in 8 types depending on the number of definable tags from 50 to 5000. Includes a license for the first HMI client (VDS Viewer) to access VDS.|
|Upgrade kit||Full-time version||NT620FJ||Upgrades the basic software license by 1 rank to increase the number of definable tags.|
|Additional HMI client license||NT625AJ||License for increasing the number of HMI clients (VDS Viewer) that can access VDS concurrently.|
The Report Package, Trend Package, Test Package, and Multi-task Package are individually available in two versions: full-time and runtime versions. Use of the runtime version allows a cost-efficient system to be built. For further details, please send the information requests to us.
|Report Package||Full-time version||NT301AJ||Helps create monthly, daily, lot, and simple batch reports. (Needs Microsoft Excel to run.)|
|Trend Package||Full-time version||NT302AJ||Displays trend graphs of data acquired to VDS and saves them as historical data.|
|Test Package||Full-time version||NT303AJ||Helps debugging by providing I/O simulation functions for debugging without a target machine, device monitor functions to monitor the connected PLCs' statuses, and more.|
|Multi-task Package||Full-time version||NT304AJ||Enables intercommunication of signals with Visual Basic programs and exchange of array data in a PLC with Visual Basic programs.|
|Extended Security Package||NT320AJ||Provides the function of protecting operation file and password management.|
|OPC Data Link Package for .NET||NT336AJ||Enables data exchange between application developed with Visual Studio .NET and OPC server.|

|DARWIN Driver||NT365AJ||Driver for connecting Yokogawa DARWIN Series units and DAQSTATION recorders.|
Taiyo Nippon Sanso Corp. was looking for a system that could be easily adopted to its plant architecture. For the following reasons, Yokogawa's STARDOM system with the FCN autonomous controller and the VDS Web-based SCADA software was selected as their control system for a Water-18O plant and other facilities.
