VDS, which is operation and monitoring software that runs on a personal computer, adds an advanced architecture to the conventional HMI/SCADA functionality such as data acquisition from various I/O devices and graphical presentation of the acquired data VDS thus embodies
a “network-based control system (NCS)” proposed by Yokogawa as a new system architecture for boosting manufacturing efficiency
• Operation and monitoring of the sites can be performed anytime, from anywhere via a general Web browser Only a personal computer with Internet access is needed, without special dedicated software, thus simplifying maintenance of the PC itself
• VDS can handle various applications by linking up diverse devices and controllers including autonomous controllers, programmable logic controllers of a variety of suppliers, power monitors, and temperature controllers The OPC client/server connectivity also enables VDS to interlink with business framework systems
• A wealth of functions simplifies operations such as message management and assures security, and provides an object-oriented engineering environment to minimize
programming effort, thus making engineering more efficient

From a small system such as connecting a single controller or I/O device, up to a large system consisting of multiple controllers and I/O devices, VDS can be optimally configured to suit any scale
Advantages
HMI clients can access VDS through the Internet and a firewall
Each HMI client computer need not run VDS software
- With just a PC running a Web browser with Internet access, operation and monitoring can be performed from anywhere
- Cheaper updating of package software The HMI server can assess VDS’s data server running on a different PC, so operation and monitoring of a different system is also possible
Up to a total of 32* controllers and I/O devices can be connected, and they can all be of different models (* For controllers/devices connected via serial communication, each RS-485/422 train is counted as one.)

VDS can interlink with business framework systems such as the production management system using its OPC server functions as well as act as an OPC client to access data residing in an OPC server
Connection from/to OPC clients
VDS, with no optional package, supports the following interfaces to allow not merely access to OPC clients from applications running in the same PC as the that running VDS but also access from remote OPC clients as shown in the figure:
OPC Custom Interface
An interface adopting the basic functions of the OLE/COM as they are (client applications are written in C or C++)
OPC Automation Interface
An interface stipulated by the OPC DA 2.0; allows for access from Visual Basic and VBA programs
(The access from Visual Basic programs is also available with the feature described in Section 4.4.)
Connection from/to OPC servers
The optional OPC Server Driver enables data access from/to a third-party OPC server based
on the tag names whether that OPC server runs on the same PC as that running VDS or it is a remote OPC server as shown in the figure (For the interfaces and methods supported, see the General Specifications for OPC Server Driver (GS 34P02G08-01E).)

The data server contains and manages data that are to be exchanged with controllers and I/O devices via the I/O object
The HMI server creates graphic windows in Web browser-compatible format
Available helpers for developing application programs include Object Builder, a suite of oriented engineering tools, and Graphic Designer, which provides many graphics parts for drawing graphics easily
object-Standard features include message management that performs integrated management of messages including process alarms, operation logs, and system errors, and process management that performs integrated management of the various programs of the VDS system

The I/O object is a component for linking various controllers and devices such as FCN and FCJ autonomous controllers, programmable logic controllers, and I/O devices Simply by plugging into the I/O object the proper driver for the I/O device or controller you want to connect, communication with that I/O device or controller will be performed
in response to input/output requests from each control object on the data server
Specifications of I/O Object
Number of pluggable I/O drivers: Up to 32 Data refresh interval: 1 to 3600 seconds; can be set for each control object (can optionally be set to 0.1 second at fastest)
Data refresh condition: Can be selected for each control object from the following:
- Periodic: Acquires data and notifies the plugged-in control object of it at a specified refresh interval
- Upon change: Acquires data at a specified refresh interval and notifies the plugged-in
control object of it only when there is a change in data value from the previous time
- One-shot: Acquires data from the specified controller or I/O device only once in
response to a request and notifies the plugged-in control object of it
- Asynchronous: Notifies the plugged-in control object of an asynchronous event upon
receipt of it
Standard I/O Drivers
FCN/FCJ driver (Ethernet) FA-M3 Ethernet driver (supporting the F3LE01-5T Ethernet interface module, Rev 3 or later) FA-M3 RS-232-C driver (supporting the F3LC11-1N PC link module, Rev 5 or later)

The data server exchanges data with controllers and I/O devices via the I/O object, and performs various processing on the field data thus acquired Individual data are managed by control objects allotted on the data server
Since VBA is implemented in the data server, control object actions and linking actions between multiple objects can be controlled using a VBA program
Control Objects
Various control objects are provided to handle diverse types of data (see the next page for details) Up to 5,000 control objects can be defined on the data server
Access to/from External Applications
Various data contained in a control object can be used not only for graphic presentations but also by external application programs via the OPC custom interface and OPC automation interface supported as standard (see Section 2.4, “OPC Client/Server Connections”) The data can also easily be used by VBA programs (see Section 4.4, “Easy Link with VB Applications”)

Device Tag Objects
A device tag object reads and writes device data in conjunction with an I/O driver, and possesses basic data processing functions such as scaling, integration, and alarm detection Exceptions: A DR (digital register) object can input and output the values of 256 contiguous bits, but has neither alarm detection nor integration function An AR (analog register) object can input and output the values of 64 words, but has neither alarm detection nor integration function and scaling cannot be specified for each of those words (Neither does an XAR object.)
Application Support Objects
These are control parts that support the actions of an application, such as generating timing signals Using optional Multi-task Package allows the use of control parts to provide multi-tasking functions such as synchronization and data sharing between the data server and a VB program
