OPC-TCP Toolkit for QNX and Linux

Ver 3.x

OPC-TCP Toolkit is a toolkit for fast development of a communication program providing link between MS Windows-based OPC-Server and a QNX/Linux-based application. This application receives data from controller and communicates with MS Windows-based OPC-Server.

As there are many Windows-based SCADA-systems and OPC Standard has wide recognition from SCADA-developers, all up-to-date controllers need OPC support.

The package was created to make OPC Server development fast and inexpensive. It consists of two main parts:
1) MS Windows-based (9x/NT4.0/2000/XP) OPC Server
2) QNX/Linux-based program connected through TCP/IP. It provide a user API for the OPC Server.

MS Windows-based OPC Server is based on the specifications OPC 2.0. It is delivered as an executable module.
QNX/Linux-based program is delivered as object files and a "changeme.c" file in source codes.

To make a full-featured OPC Server you must change a few functions. Now there is no need to make different OPC Servers for every of several different controllers. Since the version 1.1 OPC-TCP Toolkit may work with several controllers at the same time.

Http-Interface for OPC-TCP Toolkit for QNX and Linux

The http-Interface allows deliver OPC data from QNX or Linux systems to any plattform web browser.

The http-interface for OPC-TCP Toolkit is embedded in the MasterIOS program on the QNX/Linux site. User gains an offing to see the structure and current values of the whole MasterIOS data base through the web browser.
