Relay ladder logic program...

Integration of the FX-731 USB digital board with the MODBUS RLL program is complete. The program supports multiple cards. New installers are at the normal links.

We are also now including one full license of the program, FREE, with each FX-731 purchased.

We started production of videos demonstrating the ladder editor, configuration of external connections and generally how to use the program.

IDEC release...

We released support for the IDEC (OpenNet) protocol yesterday. Reading and writing of all allowed memory types and addresses is supported. A demo project was also created.

We clarified the help file regarding characters allowed in tag names. When using a browser or OPC servers/clients the range of characters is reduced.

New USB I/O board and other updates...

Yesterday we released the new USB digital I/O board. Here is a link to the datasheet.

 

Update 07/13/2012

We have several example projects demonstrating how to read and write the I/O pins of the FX-731 USB I/O card.

· Microsoft Visual Basic .NET 2010 Express

· Microsoft Visual C# .NET 2010 Express

· Delphi 2007

Update 07/13/2012

The analog input board is progressing. At present it has 13 analog inputs with 12 bit resolution, 0-20 or 4-20 mA, MODBUS RTU slave, switch selectable RS-232 or RS-485, designed to occupy any point in the circuit after the current source and with a high common mode input range.

The IDEC (OpenNet) protocol support is progressing. The configuration portion is complete and runtime support is being added and verified.

We did some testing on Windows server 2003 R2 and found PeakHMI executed without error.

We also added some protective code for DCOM configuration errors. We found during testing that improperly configured DCOM settings would cause our embedded OPC client to sometimes fail. We also verified the rule that if the OPC client and server work locally and do not work remotely, it is a DCOM setting error.

The embedded web server now supports 'digest' authentication as well as 'basic'.
