10SD-OPC		System 10 OPC Server	$ 495.00

Using the industry-standard connectivity and interoperability of OPC*, our new server gives your SCADA/HMI or DCS system flexible and efficient on-line access to data collected and processed by any Daytronic System 10, via RS232 or GPIB. OPC "client" applications are available from FactorySoft, Intellution, and a number of other prominent software developers for

	FACTORY AUTOMATION—including alarm and event handling for complete process control, with extended interfacing via Ethernet, Profibus, Modbus, etc.
	DATA MANAGEMENT—including archiving for SPC/SQC, trend and fault analysis, incident review, and report generation
	PLANT SERVICE AND MAINTENANCE—including energy and environmental management, EPA compliance testing, etc.

OPC ("OLE for Process Control") is a nonproprietary specification that defines a set of standard communications interfaces based on Microsoft's OLE/COM technology, thereby allowing real-time exchange of data among PC-based clients using Microsoft operating systems. As such, it makes possible the effective interoperation of field systems and devices with all kinds of automation/control and database software applications.

The Model 10SD-OPC software allows direct communication between a Daytronic System 10 Data Acquisition System and any application program compatible with the OPC interface standard, via either GPIB or RS232. The server is designed to run on Intel-based PC platforms with Windows NT 4.0 (SP3+) or Windows 98 operating system. It is extremely easy to install and use.

The OPC Server consists of two main parts:

Driver thread—handles all communication with the System 10 (inputs and outputs), as well as serving all device data for OPC client applications. The driver thread is started and stopped as communications with System 10 are started and stopped. Upon being started, it will first read the most recently saved configuration file. This determines the device configuration (serial or GPIB communications parameters, including the desired scan interval, in milliseconds), as well as the list of analog and digital channels to be scanned and served to OPC clients. Scanning of the listed System 10 data channels will continue until the user chooses to stop communications.

User interface—allows the user to configure the device settings, build a list of channels to be scanned and served to OPC clients, and start and stop the driver thread.

Once communications have been started, the OPC Server lets the user set a specific System 10 channel or bit to a new value (changing a bit's logic state can in turn be made to trigger an automatic command "EXECUTE" function within System 10).

For more information, or to order your copy of the OPC Server, contact the Daytronic Sales Staff or your nearest Sales Representative.
