Updated Visual Studio .NET Class Libraries From CimQuest INGEAR Add Advanced Features for Allen-Bradley Logix Family of Controllers

PHOENIXVILLE, PA--(Marketwire - August 19, 2010) -  CimQuest INGEAR, a leading publisher of runtime-free software development solutions for industrial applications, has announced the availability of Visual Studio .NET class libraries for Allen-Bradley ControlLogix and CompactLogix programmable automation controllers (PACs.) Users writing automation and control applications in Visual Basic.NET or Visual Studio C# can use INGEAR NET.LOGIX version 3.0 software to communicate easily with popular Allen-Bradley controllers, design custom communications and data acquisition applications, and deploy them on as many machines as they want, without paying additional license fees.

"The better the information plant personnel have regarding operations, the greater their ability to manage costs, output, quality, and ultimately -- profitability. Some of the most valuable data lies within the programmable logic controllers (PLCs) that automate assembly lines. Manufacturers typically deploy PLCs machine-by-machine, so accessing that data can be a real challenge. This new set of class libraries provides anyone who knows Visual Basic.NET or Visual Studio C# everything they need to communicate with some of the world's most popular Allen-Bradley controllers," said Chuck Karwoski, president of CimQuest INGEAR.

Among the advanced features of NET.LOGIX 3.0 is a new PeerMessage class. The PeerMessage class for Unsolicited Messages waits idle in a passive state for the Allen-Bradley controller to send data via MSG instructions. When the PeerMessage class receives the communication, it fires a notification event with data so the user application can immediately process it. The PeerMessage class can receive MSG instructions from ControlLogix, CompactLogix, MicroLogix, ControlLogix Gateway, as well as SLC 5/05 and PLC-5E family of controllers. ControlLogix and CompactLogix can send unsolicited messages using native tag names with structured and atomic data types, or data table address format. The PeerMessage class automatically distinguishes between the various message formats so implementation is consistent between all data types and all Allen-Bradley PLC's.

Another advanced feature in NET.LOGIX 3.0 is the new DTEncoding class which facilitates reading and writing User Defined Types (UDT's), Pre-Defined Types (PDT's) as objects with without having to read/write each atomic member individually.

INGEAR NET.LOGIX software provides an alternative to OPC-based driver software for Visual Studio .NET developers. Unlike OPC which is a middleware application, NET.LOGIX is an embedded class that provides a direct communication channel to Allen-Bradley controllers. The sensible API of NET.LOGIX 3.0 software provides an easy-to-use interface that result in very fast communications without the overhead and recurring cost of OPC servers. The users of NET.LOGIX have unprecedented flexibility to develop their own Windows programs, system services, class libraries and ASP .NET solutions without being boxed in by OPC constraints.

Like all solutions in the INGEAR.NET software family, NET.LOGIX 3.0 is a runtime free class library that simplifies building, developing, and deploying connected systems for manufacturing applications using Visual Basic .NET or Visual Studio C#. It uses only three primary classes of .NET code: one of which manages the PLC, one which manages the data that are read from or written to that PLC, and one which manages groupings of methods, properties, and events to optimize read/write operations on a collection.
