As a Pascal developer, we would like to offer you the opportunity to work with the OPC standard in the familiar Embarcadero (Codegear, Borland) Delphi and Lazarus environment, we have developed a OPC software toolkit (SDK, Framework, Toolbox) supporting the most common OPC interfaces and protocols: OPC UA (Unified Architecture), XML DA & classic OPC (Data Access DA, Alarms & Events AE and Historical Data Access HDA).
Delphi Opc Client Software
Our powerful dOPC Toolkit allows you to build OPC client applications with just a few mouse clicks. E.g. dOPC includes a GUI component that allows you to bind OPC item values directly to properties of visual components, such as labels or edit boxes.
Please note, the trial version works only with Delphi and RAD Studio editions, not with Lazarus (Free Pascal). Furthermore it is not possible to create 64 bit, Android, MAC OS and iOS OPC client programs with the trial version.
We have therefore put together a collection of information on OPC programming with Delphi, including Delphi translations of the published custom OPC interfaces, along with source code for a simple console client and some demonstration servers.
XRTL is an open source collection of Delphi packages which includes code for both a Data Access 2.0 server and client - the demo server has passed the full OPC Foundation Compliance Test for DA 2.05a. Other XRTL packages include functions for math, I/O handling, zlib compression and more.
dOPC DA version 3.0 brought support for DA 3.00 and OPC XML-DA 1.01, making it easy to develop clients with support for both COM DA and XML-DA server access. Also included in version 3.0 is is a simulation OPC server.
Prosys Sentrol is a Delphi/C++Builder component library which provides a "Rapid OPC Application Development Framework". This includes fully compliant OPC DA client and server functionality, as well as database, visualization and other components.

OPCWare Client Developer is the most versatile productivity toolkit for OPC client developers. It is the ultimate collection of OPC interface components for Visual Basic, Delphi, Excel, Labview, Visual C++, C# (C Sharp), VB.NET, ASP, MS Office, and other VBA-enabled and ActiveX containers. 4 royalty-free runtime distribution products are included, each one developed for use in all ActiveX containers which relate to user-interface and process data interface. These components are both innovative and unique, and very popular in the process control, HMI, scientific, engineering, test and measurement, simulation, and data acquisition communities. Using these components you can build first class OPC client applications with your language of choice.
This software developer's productivity toolkit includes an OPC Server Explorer, an OPC Item Explorer, an OPC Group and an OPC Explorer (featuring treeview and listview visualization capabilities similar to Windows Explorer) - that's 4 components, one .ocx file, several demos, comprehensive help files and numerous source code samples (VB6/VBA/ASP/VBScript/C#/VB.NET/Delphi/BCB etc.).
Many of our customers are owners of independent software businesses, others are high-level product managers, and others are senior engineers. Their end-users are important to them, and their applications are usually complex. Their bottom-line directly depends upon the OPC related functionality embedded in their product(s). When compared to all other customers in the market, these customers must spend the most time weighing up their options because their needs are the most challenging and important.
"I spent a week evaluating several Windows controls and found OPCWare to be the easiest to use and the support was almost immediate when I had a question. In total it took me three days from start to finish to integrate the OPCWareX control into our product....OPCWare helped make me look like a genius to our company and will be my first stop for any further OPC development we require. Thanks guys."Chris Bowen, Senior Software Engineer with Syscon International, a leading real time plant information software manufacturer, USA.
That is worth thinking about. When it comes to our customer's productivity, reputation, and product competitiveness - their bottom line in fact - they choose OPCWare Client Developer above the competition. In fact, many of our customers have spent more time making that choice than they've spent actually using our software, such is it's productivity. If your OPC requirements are as serious as this, no other tool or vendor is more focused on your success. Data Layers can even provide custom paid enhancements and source-code escrow services if you need these insurances.
We continuously allocate members of our development team to adding and improving features and code that most developers never see. But some do and each perspective is as important as the next. Then when the end-user of the software bombards it with data from multiple OPC servers from different vendors, some OPC compliant, some not, OPCWare Client Developer is there to keep things intact. Or when your development team has a major new requirement, or needs to develop in a different language, there is a range of supports available such as sample code, direct access to the experts, and knowing that you are not the first to do this, so the risks are minimised.
Here's a quick software quiz that could make a dramatic impact on the amount of time and money you spend on process and device connectivity. Answer these 5 questions:(Simply check YES or NO)
Our OPC Client development product, OPCWare Client Developer is the essential suite of OPC software components used by hundreds of engineers and developers worldwide. You too can easily use it to leverage and connect to the hundreds of OPC drivers that are available off-the-shelf today.A world class product, Version 3.0.x is unique in its range and depth of features and functionality, offering unprecedented development speeds, as well as high performance and unlimited flexibility for your OPC client applications.

For industrial automation users who need to assemble interconnections between industrial devices and applications from different vendors, OPCWare is a suite of software components that enable rapid integration of software and hardware for data acquisition, monitoring and control. Unlike closed, proprietary systems, which require expensive, specialised support and often third party resellers, our products are based on open, industry standards, and are manufactured, marketed, sold and supported by us.
OPCWare is OPC software, which is an implementation of the widely adopted API standards embodied in OPC (OLE for Process Control) technology. OPC is also Openness, Productivity, Connectivity.Our OPC component toolkit OPCWare Client Developer is the leading OPC Client toolkit that can be used with Visual Basic, Visual C++, Delphi, Excel, Access, VB.NET, C# and Labview, plus several other ActiveX containers. It provides easy to use powerful OPC client functionality delivered in the form of reusable ActiveX controls. These OPC ActiveX controls embedded in your applications will connect to Off The Shelf OPC servers which are widely available to add opc communications to a range of devices including PLCs, weighing scales, label printers, dimensional gauges, temperature transmitters.
Using software created with OPCWare Client Developer, OPC connections are easily set up, and the process data can be moved in either direction, so you can read or write OPC data for monitoring and controlling, or you can log process data to a database, insert it into a spreadsheet, or display it in a web browser.New devices, controllers and PLCs can be added easily, and your application code does not need to be changed.All you need to do is decide what to do with the data. We provide source code that shows how you can use our components to display your OPC data graphically in real time, and how to log it to simple databases such as MS Access, or enterprise databases such as Oracle or SQL Server. 2ff7e9595c
