Unfortunately, upgrading is not an option at this time.
I have found a work-around though: I am developing clients for a number of our production cells where the machinary displays are not readily accessable to the workers. The OPC client has a different window for each cell that displays all the data for the machinary in that cell. I have another window, accessible only by engineering, that controls the various parameters for displaying warnings for suspect data.
I am using Client Tags to transfer these parameters between the production windows. In order to distribute any parameter changes to the other clients, I am using FTP (which I learned about here in the forum) as it is about the only mechanism available on our production thin client computers. My original idea was to loop through all the Client Tags when loading and saving the parameter changes. Instead, I have modified my Client Tag names so they are consistently similar to the component names in the parameters window. I then can loop through all the components in the parameters window (using event.source.parent and .getComponents), changing the component names to the Client Tag names. It’s probably not the best solution, but it will do until I become more familliar with Ignition.
Thanks again for all your help.
