NET.ABLINK 3.0 Released with Unsolicited Message Support
NEW ! – Unsolicited Message Support
Among the advanced features of NET.ABLINK 3.0 is a new PeerMessage class. The Peer Message class for Unsolicited Messages waits idle in a passive state for the Allen-Bradley controller to send data via a MSG instructions. When the PeerMessage class receives the communication, it fires a notification event with data to so the user application can immediately process it. The PeerMessage class can receive MSG instructions from MicroLogix, SLC, PLC-5, ControlLogix, CompactLogix and ControlLogix Gateway. 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.ABLINK 3.0 is the new DTEncoding class which facilitates receiving User Defined Types (UDT’s), Pre-Defined Types (PDT’s) as objects in unsolicited messages from ControlLogix and CompactLogix controllers.
INGEAR NET.ABLINK software provides an alternative to OPC- based drivers software for Visual Studio .NET developers. Unlike OPC which is a middleware application, NET.ABLINK is an embedded class that provides a direct communication channel to Allen-Bradley controllers. The sensible API of NET.ABLINK 3.0 provides an easy to use interface that results in very fast communications without the overhead and recurring cost of OPC servers. The users of NET.ABLINK 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.ABLINK 3.0 is a runtime free class library that simplify 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 the data that are read from or written to that PLC, and one manages groupings of methods, properties, and events to optimize read/write operations on a collection.
