New features include TCP/IP Function Blocks, BBH FSoE Master + SafePLC with KAS-IDE and AKD2G w/ SMM, KAS IDE-WorkBench Improvements, new File Management functions, DriveParamStrRead, Multi-select PDO objects, new axis parameter to read PLCopen user units, and more!

The AKD2G can be used in a KAS Motion/Machine control system. This application note outlines new/different features to be cognizant of when developing a KAS application that includes  AKD2G drives. After reviewing this document, contact a KAS application engineer if you want more detail.

WorkBench (version ≥ 2.2.2.4811) has some accessible parameters to tweak the way data are exchanged with the drive. Keywords sent to the drive and answers returned will be grouped together to build bigger packets of data. This is particularly helpful on networks with high latency. It is also useful for slowing down the polling interval to avoid overloading the communication channel on slower networks.

These parameters are accessible in the WorkBench configuration file, which is usually placed in the install directory:

Debugging interaction problem between WorkBench and drives may be facilitated by using the built-in logging mechanism.

Where are the application and the log files in your system:

The easiest way to access the application or the log files is to open the About box in WB, it will give you the full path to the application and log folder:

WB has 2 log files:

The Load On Startup listbox on the Scope Settings screen in Workbench is by default disabled ( greyed out ).

Under the Tools->Options pull-down menu in Workbench there is a box that can be checked to enable this feature.

The checkbox is called "Reload Scope Settings when Scope page is Opened.

The fault history in Workbench shows a number of days, hours, minutes, and seconds for each fault occurrence.  This is the runtime of the drive.  It is the ammount of time that the drive has been in a booted-up state, whether enabled or disabled.

If a fault occurs while Workbench is connected to the drive, then Workbench shows the computer's time and date of when the fault occurred and also shows the elapsed time from when the fault occurred (after pressing the Refresh button). 

From the Fault History page:

In late 2013, Workbench was tested to be compatible with Windows 8.

 

Cloud for Workbench on KDN

I had an idea related to having an online storage location (cloud) that Workbench could connect to and store a customer’s parameter file and/or program file.  I approached the Workbench development team about this, but left it as a “nice to have someday in the future” kind of thing.  But with KDN having a login profile available to every customer, maybe it could be used to developed this.  Part of my idea for a cloud was to have multiple login layers for each login profile.  A customer can create the profile an
