Anyone noticing C More EA5 screens are painfully slow to react to touch?
I have EA5 screens in three locations now. Compared to my EA9's and 7, the reaction to screen presses is very slow. 1-2 seconds delays for screen changes or pushbutton operations. No warnings or errors, just slow. Are the processors in the 5's worse than the predecessors?
Do you have a project, having this issue, you could share so we could look into it here? You could private message it to me, if you prefer.
Are you referring to the CM5? IME they were equally as slow as the EA9. I experienced considerable lag for anything tied to a PLC tag, screen changes and internal tags would be quick however. The issue in my case was a preference for screen design around hierarchical pop-ups. C-More continuously updates the pop-ups even when they are not called. Bitmaps and visibility tags also cripple it. In the end, reverting to unique screens in lieu of pop-ups, compromising on reducing vis tags, removing bitmaps where possible (only way to get an invisible pushbutton) and reducing to bare minimum of data on each screen restored performance to an acceptable speed. Still not great IMO and the platforms I have switched to since are much more responsive to these type of designs. Still have some CM5s for simple programs though.
I had a similar issue with my first use of the CM5. I had a project that was converted from EA9 and there were a few tags that were used as visibility bits or something that wasn't really evident as I was commissioning. In my case either the tag names were correct, but were pointing to a PLC that didn't exist or wrong IP, etc., or the tag name was correct and the PLC was correct, but the actual address was wrong, e.g. C0035 vs C0157. The broken tags or PLC targets caused an issue with excessive delays. I forget right now what the method was, but basically I was able view the tags for each screen and was able to hunt down the disconnected tags and correct them. Lagging issue solved. I hope this is helpful to you.
Interesting, I found that intentionally creating a PLC-499 error for a non-existent tag actually improved the response of pushbuttons oddly enough.
I have a couple of popups and some visibility animation turned on that all seem to work fine after fixing my issues. The delays were ridiculous at first. It would take sometimes as much as 5 or 6 seconds after pressing a button to get the response.
INTERESTING. I will look into these ideas. It was converted EA9 projects....
Did you ever find a solution to this? I'm having the same problem. 1-3 second delays with every button press.
I have 2 CM5 HMIs talking to the same 2 PLCs (micrologix 1400 {downstairs} & Click {upstairs}) located about 50 feet apart (ground level and roof level). Screens are 100% duplicates of each other other than IP addresses (which are verified 100% correct). I'm using the Stride 8 port ethernet unmanaged switch downstairs, and a stride 4 port unmanaged switch upstairs.
I have 2 of these setups running. Both setups have the same problem where as the roof is very slow to respond to any/all button presses / screen changes. This is not weather dependent or anything like that. Screens are kept at optimal temperatures year round. We have a panel heater and cooler installed in the roof panels to maintain temperatures as needed.
