Can you trust your critical text message notifications to be delivered by your wireless carrier?

August 24, 2015 / 0 comments / in Support  / by Jacob Allred

Here is a scenario that I’ve seen crop up several times in the last few months:

A point enters the alarm state and an SMS notification has been sent, but several hours later no one has acknowledged it yet. Investigation begins into this issue and I notice that the notification service (GNS) has logged a successful send to my field techs’ wireless carrier’s email address, there are no errors reported, but no one has responded to the callout. I call the tech and he says he never received the notification.

Tired of Attending the Same Old Events? Try Throwing Your Own Custom Event

August 18, 2015 / 0 comments / in API Applied_Engineering General Studio_Tips  / by Blake Miller

In my previous post How to change a tab strip selection, I discussed the use of HyperLinkSys as a means of passing data from a nested view screen to its parent screen. In that technique, the data passed from the nested view was used to change the selection of a tab strip on the parent screen. In keeping with the theme of initiating an action from a nested view, I will present a different technique using custom events for more complex interactions.

Using references to display a packed word value

August 03, 2015 / 0 comments / in General  / by Ryan Ackerman

Have you ever run into a situation where a single value on a device could represent multiple values at the same time? How would you display a nice string representation for all the potential values? I recently saw this problem solved on an Emerson device where a TLP contained multiple values packed into a single byte. The solution used a combination of multiple reference DEIDs and a few associated enumerations.

Playing Battleship with the HSS

July 29, 2015 / 0 comments / in General  / by Walter Goodwater

Scripting in CygNet is great…when it works.

Debugging script issues in Studio (especially without a just-in-time debugger like Microsoft’s Visual Studio) is like a game of Battleship: “Is there a bug at B9? No? OK, let’s try a MsgBox at H2…” And don’t get me started once you have to deal with Nested Views.

But even worse is debugging script issues in the HSS. That’s like playing a game of Battleship while blindfolded, ten miles from your opponent, and you can only make your guesses via Morse code. And did I mention your opponent can move the ships around? It’s enough to make HSS and VBScript (and maybe CygNet for that matter) four-letter words in many a SCADA admin’s vocabulary.

Maybe we can help.

CygNet .NET API: Integrators, your life just got (a wee bit) easier

July 27, 2015 / 0 comments / in API General  / by CygNet Blog Admin

I’m not sure how many of you noticed, but with the arrival of CygNet 8.1.3 came a fresh face in town to help with all your API woes (well, some of them anyway).  Our first round of .NET API assemblies were unleashed into the world to bring hope and joy to all who write their own integration applications on top of the CygNet system.

Up until this point, you’ve had a couple of different tools at your disposal.  CygNet ODBC, the COM scripting API, and the Enterprise Integration Suite are some of the different options you have to select from when you want to build an application to interact with CygNet. Each of these tools has its own set of advantages and disadvantages.

Update on CygNet mobile

July 16, 2015 / 0 comments / in General  / by CygNet Blog Admin

Since WESC is now ancient history, I wanted to give you all an update on our new mobile product.  For those who haven’t heard, we started a research project back in April 2014 to understand what our customers wanted from a CygNet mobile solution.  The research told us that lease operators were most in need of an app to view data and acknowledge alarms from the field.  That is what we have been working towards ever since and I’m pleased to announce that we are now feature complete!  That being said, the official release date is still Q4 as we have some minor issues to address and want spend some time focusing on performance.

Why Token Based Polling: Reduced Overhead

July 16, 2015 / 0 comments / in Measurement  / by Jacob Allred

In my last post I talked about why TOKEN-based polling is the new best way to get your EFM data into CygNet Measurement; it’s now time to start backing up that claim. Let’s start with a simple one…

How does CygNet Measurement help me to reduce the polling overhead of my devices?

CygNet ODBC and LEFT OUTER JOIN

June 19, 2015 / 0 comments / in General Patch  / by CygNet Blog Admin

The CygNet ODBC driver has recently been patched such that it returns the correct rows for a query that processes the results of a LEFT OUTER JOIN with a subsequent LEFT OUTER JOIN. Previous to this patch, such a query would not return the correct rows and either generate an unknown exception in the associated log file or cause the application to crash.

How to change a tab strip selection

June 18, 2015 / 0 comments / in Applied_Engineering Studio_Tips  / by Blake Miller

Well as a similar joke goes, first the tab strip has to want to change.

Tabs are commonly used in screen navigation. They do a good job of helping us organize our screens and they don’t require a lot of screen real estate. I used them extensively when building CygNet for Production. So much so that Applied Engineering built an entire management system to control the configuration of the tabs, but that’s a story for another day.

Announcing Sniffer Lite

June 04, 2015 / 0 comments / in General  / by Walter Goodwater

As Rick teased in his on-going series on screen performance enhancements, we are happy to announce the release of CygNet Message Sniffer Lite. This tool is designed to help the CygNet administrator understand exactly what messaging is happening between CygNet clients and services to help diagnose problems and improve performance
