INGEAR.NET.LOGIX 2.0 (build 2.0.908) update is available for immediately download.  This update corrects the following problems.

• STRING data type writes would fail when used in a TagGroup collection.  (i.e Controller.GroupWrite operation)
• Controller.GroupRead would report all Tag.QualityCode as QUAL_BAD if there were one of more invalid Tag classes in the TagGroup collection.

INGEAR.NET.LOGIX is a Visual Studio .NET class library for developing data acquisition and control applications for Allen-Bradley Control Logix, Compact Logix and Soft Logix programmable automation controllers for Desktop, Web and Windows CE deployment.

We had a question come to us asking if there INGEAR.NET.LOGIX had connection limitations for Allen-Bradley ControlLogix processors.

Basically, the INGEAR.NET.LOGIX  for Allen-Bradley ControlLogix / CompactLogix (or any of the INGEAR.NET class libraries), do not restrict or limit in any way, the number of simultaneous connections to multiple PLC’s.    In addition, there is no limit on the number of tags or data points that can be accessed in the PLC.

Limitations are  related to available system, network  and PLC resources such as:

• Memory
• Disk Space
• Operating System
• CPU Speed and Utilization
• Network Speed and Utilization
• PLC scan times

• INGEAR.NET.ABLINK – For Allen-Bradley MicroLogix,  SLC and PLC-5
• INGEAR.NET.MBLINK – For Modbus TCP/IP, Serial (RTU and ASCII)
• INGEAR.NET.GELINK – For GE-Fanuc SRTP Ethernet PACSystems, Series 90 and VersaMax

As the world anticipates the release of Windows 7 this fall (October 2009), followed by  Visual Studio 2010 (sometime in 2010),  the question begs to be asked is “Will myVisual Basic .NET and C# run? ”.  The answer is a great big YES.

Windows 7 (x86 and 64-bit)

We’ve tested the following INGEAR.NET PLC class libraries on Windows 7 RC.  We do not anticipate any issues when Windows 7 is offically released.

• INGEAR.NET.LOGIX 2.0 for Allen-Bradley ControlLogix and CompactLogix
• INGEAR.NET.ABLINK 2.1 for Allen-Bradley MicroLogix, SLC and PLC-5
• INGEAR.NET.MBLINK 2.1 for MODBUS Devices and Controllers
• INGEAR.NET.GELINK 2.0 for GE-Fanuc SRTP Ethernet

Visual Studio 2010 (x86)

There were no problems migrating existing our Visual Studio 2005 / 2008 existing projects to Visual Studio 2010.  When we created a new Visual Studio 2010 project, the INGEAR class libraries did not appear in the list of available assemblies in the Add Reference… dialog.  We needed to Browse… the \Program Files\INGEAR.NET\ folders to add them to the project.   This is a minor problem related to the install sets and will be corrected by the time Visual Studio 2010 is officially released.  As this time VS2010 64 bit is untested.
