In our current project, we are using Windows 7 64 bit machines. This is the first time we are using Ignition on 64 bit machines and running into lot of issues.
Initially, I installed 64 bit java and 64 bit ignition. With this configuration, Ignition could not establish connection with Kepware OPC server (using OPC-DA method). I uninstalled both Ignition and Java. I installed 32 bit version java and 64 bit version ignition. With this configuration, Ignition could establish connection of Kepware OPC server (DA method not UA). However, I could not launch the designer. It used to pop up error message “Unable to lauch applicatoin”.
So, I uninstalled 64 bit Ignition and installed 32 bit version. Now, communication to Kepware OPC from Ignition is working and also the Ignition is working.
Since this project will be moving to commissioning/production phase from next week, I would like to know is the current configuration (32 bit java with 32 bit ignition on 64 bit machine) is a stable configuration or do we need to move back to 32 bit machines? Even if this is stable, what are potential limitations that we will run into in the future?
