Retarget problem

I am trying to retarget to a remote server and open up a screen.
The following script is on a button and does not work.

system.util.retarget(“Test”, “noaplupcs01:8088/main”,[“Weather”])

It should be the following:system.util.retarget("Test", "noaplupcs01:8088/main", {}, ["Weather"])You are missing a third argument which you can pass in an empty dictionary. Next time, if you get an error, post the details of the error to help us out.

It attempts to work, It opens the Login Screen, (which is set to auto login and does auto login if you just open the project). ???

After loging in the main screen opens not the “Weather”. If you click the goto button for the Weather screen. It just closes the project.

Which version of Ignition are you using?


I have done some local testing. It does not like Active X running IE. It shuts down everytime after it retargets 1 time. (Ignition exists out). Without Active X , it works ok.

Below is the error code when it closes

Register to memory mapping:

So 7.29 is the local version, what version is the remote server running? Just to be clear, the ActiveX IE component is in the targeted project, not the source project, correct?

The previous testing has been done on the local server.

yes IE is in the target project

Which version of Ignition is the remote server running?

Sorry, all versions are 7.2.11 , Java 1.6.33

I hate to be a downer about this, but (exactly as you discovered) the ActiveX components and re-targeting to not play well together.

We currently do not have any workaround for this, except of course not using ActiveX components.


Maybe there is a different solution.

What I have is several large TV’s displaying Production data with scrolling screens and I wanted to add a screen showing the current weather, but the client PC does not have internet access, so I was going to pull it off another server thru Active X.

Any other thoughts or a better method.

Does the Gateway have internet access?

Yes it does

Great! There are a lot of ways to skin this cat but the basics are that you want to query for weather conditions on the Gateway, and store the results as something that the Client can read (most likely as tags).

It just so happens that in our Module SDK there is an example of how to write an OPC driver that fetches the weather from Yahoo weather. This would certainly work, but is overkill (downloading the SDK, compiling the example into a *.modl, getting the module signed, etc is a bit of work.)

I would approach it this way: write a python script that runs as a Gateway timer script that fetches the weather and simply writes it to some Memory tags you’ve set up. Conveniently, there is an example of what this script might look like in the User Manual

Thanks Carl

I will do some Testing with your suggestions.

I got one ready to go somewhere around here. Let me see if I can find it…

Okay, here it is. The script, the images, the tags.

[size=200][color=#FF0000]WARNING! DANGER! DANGER![/color][/size]

[size=150][color=#FF0000]Do not do a straight import of the tags. Doing that will replace whatever Tag scheme you have and replace it with just the weather tags![/color][/size]

Instead, export your current tags-- you probably should it twice, one as an easy backup. Just in case. :wink:

Then copy/paste the weather tags into the csv file and re-import.

The script was shamelessly borrowed from IA from a long time ago, the images from somewhere else that I don’t quite remember. :confused:

The Image tag needs to be changed to point to whatever path you will use.

The script is used as a gateway timer script.

I think that covers everything. (1.92 MB)

Okay, everything except a window to play with… :laughing: This is in v7.2.11, so you should be able to import it with no issues.
