Hello,
We have probecard with EEPROM memory that we are reading from and writing value to.
The vendor supplies DLL allowing to read/write value to the memory.
The software engineer is able to write C# application as well as JavaScript and simple webpage to do the reading/writing.
For the webpage(JavaScript), it’s just a simple form with fields. User enters values and click button to write data to the memory.
Our department develops Ignition application for other purposes but there is a new request to integrate read/write functionality to our Ignition application.
I’m seeking an easier route by trying to use web browser module. I was thinking that whatever it’s running in the web page, should be fine with the web browser component; unfortunately, it’s not.
Looking into the Javascript and I found that the ActiveXObject is being used which I believe that it’s not supported anymore.
After extensive searching in forum, I know that ctype is limited in Jython.
Native Java might be another alternative but I’m not certain.
Anyone has any suggestion what should I do?
