I just added a new PC to a system mainly to provide a way to drive a 4K display with PAC Display.
Up till now, I’ve been using an old PC with Win XP on it, and thus limited me as to what version of PAC Project I could run.
This new machine is running Win 10 Pro. It’s a much faster computer than the old XP machine, of course. It’s an Intel Core i5-8500 @ 3.00Ghz
8 GB of RAM
With a 1000GB NVMe PCIe 2280 M.2 SSD as the main “hard drive”.
It seems pretty speedy to me!
To start out, I’ve only got a 1080p monitor connected, but the built-in graphics will run at least one 4K monitor.
To be able to use this new PC with Win 10, I downloaded and installed the latest version of PAC PROJECT Basic. This includes:
PAC Display Configurator Basic
R10.2a Build 0004
PAC Control Basic
Build Date: Nov 27, 2018, Time: 12:23:11
I copied my existing PAC Display and PAC Control programs over from the old PC to the new machine.
I updated the firmware on all of the controllers and brains in the system with the exceptions of:
1 SNAP-B-3000ENET, which has R7.1i
1 SNAP-UP1-M64, which has R7.2i
The other controllers and brains in the system are:
1 SNAP-PAC-R2 which now has R10.0f (this is the main controller for the system)
3 G4EB2s which are also now running R10.0f
I loaded the existing PAC Control program into this new version of PAC Control, and then re-saved it. I didn’t change anything in the program. I compiled it and uploaded it to the main controller (the R2), and all went well. The system seems to run fine, just as it has been.
I loaded the existing PAC Display program into the new version of PAC Display, saved it, and am now executing the “new” runtime.
All of this works, but strangely, the version running on the new PC is very sluggish. Mouse clicks to bring up different windows are slow to respond. Even the highlighting of selections as I move the cursor over them takes several seconds.
Upon initially starting the runtime up, the windows draw slowly, taking perhaps 15 seconds to draw and populate with data.
And while I have a number of trends set to update at 1 second intervals, they respond much more slowly. I also have the real time clock data, read from the controller, displayed on several windows, and it updates at between 6 and 8 second intervals, skipping the times between.
I am also running my old version of the PAC Display runtime on the original old, slow XP machine, and it still updates every second, and responds smoothly and quickly to mouse clicks in the pull-down menus, and on buttons and controls in the MMI itself.
Shutting off the PAC Display on the old XP machine doesn’t improve the response of PAC Display running on the new PC. And other operations and programs running on the new PC run fast and smooth even while the MMI is up and running (sluggishly).
I figure there’s some new feature or setting in this years-newer version of PAC Project that I need to set up correctly, but I’m not sure what it would be.
I always appreciate everyone’s time to answer questions on here. So thanks in advance for any helpful suggestions.
