Do-more CPUs and Do-more Designer Software / Re: HTTPCMD Timeout

In this particular case the server is ours, so we can allow for a greater timeout.  I dug through my code to see if I could possibly suspend some programs but nearly all make sure of rising/falling edge contacts that would be missed while the program is suspended.  So at least for our situation I would really love a way to just extend the timeout so the PLC has more time to compute the response.

That's why going the route of making it a "language" that is both viewable and editable will make it be much more intuitive (vs trying to make it "view only" via "reverse generate" a SFC-like flow from any kind of stage Ladder code).

You are so right.   The Cutler labeled Deltas (and I assume Deltas to this day) had a weird idiosyncrasy where you could display in various forms, I think LD, SFC, and IL? maybe, but one of the views, LD I think, was the primary so all changes had to be made there, and I don't think they even automagically propagated to the other views, you had to manually update.   It was extremely weird and a total pain.   And Cutler US had one guy on tech support, so he wasn't always there, and he never learned to use the SFC, presumably because he didn't think anyone was going to want to use it, but they still made sure to include that the PLC had SFC in their advertisements!

Secure Modbus TCP or Modbus/TCP Security

Adds TLS support and is being supported by many drivers for SCADA & HMI Packages.

What are the chances this timeout could be editable?

I have some busier PLCs that seem to struggle doing some of the TLS stuff within the 30 second timeframe.  Typical scan times aren't crazy but average 11-12ms which based on wireshark data has the TLS response computation right at 30 seconds.  If I manually suspend programs to lower my scantime then the HTTPS completes within the 30 second timeout.

I'm sure it could be, it's hard coded now. At the least we could make it accessible via DEVREAD/DEVWRITE.

A big concern is how tolerant the server is when the TLS handshake goes long. Many servers drop the connection at 15 seconds.

I always use the 2D tokens.

Me too.

Sorry - my bad - you also have to set every instruction class to use the "default" box background color in the toolbox's class background dialog.

You have to use 2D tokens for the general box background color to work right.  Ladder Options Display has that setting.

Otherwise, you have to do what you did for 3D tokens.  Not sure why RGB 000000 doesn't work (080808 worked, like you said)

For anyone playing around with ladder "dark mode," using pure black for Box Instruction background colors doesn't seem to work.  I could set it, but the ladder didn't update when I hit Apply and if I left/returned to the Box Instruction Class Background Color Setting popup, the colors were back to defaults.

I even tried running as an admin and it didn't work.  What DID work was using a color that was ALMOST black.

So, that's weird but can worked around.
