RE: ControlLogix 1756-L905TS Built in Ethernet Ports Unreliable

"The logic also at times fails to perform a message read of the CPU port IP address, this seems most likely to fail on power-up." This also isn't a thing the AOI does. It uses an IPv4 string provided in the passed client parameter UDT. The AOI converts this to a 32-bit IPv4 address, but the original ...

Is your 5590 in Dual-IP or DLR mode? Can you test this on a 5580? I wrote my own MBTCP AOI that handled connection loss and recovery across various paths and configurations (the local port on a 5580, EN2T, EN3T, EN4T, and the ports on a 5380 or 5480 in Dual-IP or DLR mode) . It worked, but I recall ...

I fixed being stupid and drew up the map as a scaled BMP canvas, wrote it to file, then used the web browser ActiveX object to redraw it. It's running wonders around the previous crackpot method which is still used for the map scale, so I think it's fair to say that polygon groups actually work great ...

Very true. In this clip, draw times per update simply remain... expensive (the snipping tool resolution also doesn't do it justice). It's just the sum time to set the color of 64x polygons and shift a pair of polygon groups. I created a second tag group for the redraw trigger so it stopped blocking ...

Found that previous integrator code related to overall display navigation has been hammering the backend/VBA subsystem across the project all along. I removed this code, fixed navigation, and the color map update/draw no longer grows sluggish over time. Map updates are now reliably sub-second (no sliding ...

That's correct. I'd like to try it when we upgrade, but it's months away. For now, I'm troubleshooting some timing issues with the display. VBA pushbuttons are basically very slow to respond. How are events triggered? The screen used to grind to a crawl but I fixed it by increasing the tag update rate ...

Johann, that is an interesting point about DINT packing down to 16 elements. My only concern is about whether the tag group can provide all element values atomically. -------------------------------------------

Our site is uses v12, we've planned to upgrade, so I don't know if this has been addressed in newer releases. Background: I had to resort to VBA to get creative drawing a scrolling color map. Multi-state indicators had ruled themselves out for load times and overhead when I had less than half of ...

RE: Logix Designer Alarm Manager: Monitor Alarms by Class/Group/Severity/etc.

Found In Egroup: Automation Control \ view thread
You can do this without the HMI. It essentially involves a need for two code blocks/AOIs that work together in what's structurally a "bus-style" relationship. (1) is the Alarm block itself. It can just sit on a rung and accept whatever condition you throw at it to trigger. Or suppress, shelve, and so ...

I caution against steering away from a standalone alarm model. "There are multiple ways to specify how these alarms are to be separated, whether by severity, class, or group, but none of these can be used as a form of filter criteria within the logic itself." Why not? What are you trying to do, specifically? ...

APEX is backplane-related and the error possibly indicates a fault. Is the EN2T module in the IO tree keyed (compatible/exact) and expecting v11? The processor won't establish connections to child modules if it can't connect to the parent EN2T. You can either change the tree module to expect v12 or ...
