Scheduler released...

The scheduler has been released, November 5, 2012. A short video has been created and posted.

Various updates 11/1/2012...

We released a minor update to the HMI today. We added more visual feedback to user buttons when pressed, added another configuration setting to the alarm panel, corrected an issue with OPC client pulse commands and corrected a broken link in a help file.

A new version of the free MODBUS ASCII slave program was released. It provides better timing on incoming message.

In work in progress; the HMI has included a task scheduler for several years and it is good for scheduling one time or recurring task. The task scheduler does not take the place of a ‘scheduler’. A scheduler, that provides start and end time triggers as well as overrides for dates, like holidays, the ability to delay a series of commands, grouping of outputs and actions, inhibits, etc..

The new scheduler should be released very soon.

Addition to trending...

The trend graphic element now supports "limits" and "banding".

Limits are static lines that can be used to display an alarm level, setpoint value, etc..

Banding can be used to display a range.

Any number of limits or bands can be added to the trend.

HMI update 9/13/2012...

Today we released a new version of the HMI with support for Toshiba computer link protocol for UDP/IP. The previous release was for RS-232/485. The same register types and data types as RS-232/485 are supported.

The HMI now has the ability to change the tagname of a trend pen at runtime. One or all pens can be changed with one command.

Toshiba computer link protocol...

Today we released a new version of the HMI adding the Toshiba computer link protocol.

·        RS-232/485

·        X, Y, R, S, T, C, D, L registers

·        Bit, Word, Longword, Float, String

HMI web server update... (Part 2)

Yesterday we released a new version of the HMI to expand the built in web server features.

The web server can now parse a page request from a web browser for "tags". The tags point to internal HMI data. For example, values collected from a PLC. The tag is replaced with the value and the web page is sent to the web browser. The remaining text in the page is unmodified.

Also, values can be written to the server using a URL with the correct parameters.

This new feature allows for the development of web pages in the programming language required with data collected from the HMI.

MODOPC & LogixOPC...

For each program we released a new demonstration project.

The project demonstrates how to read/write data from/to the OPC server using Excel as the OPC client. Excel 2007 was used.

Each project includes an Excel spreadsheet, with VBA scripting, a program project and a short video covering the parts of the demonstration.
