The panel had firmware 1.6.2 and I updated it to 1.8.0.
For the same simple visualization in MappView, the panel sometimes disconnects with the message “Lost Connection” and the visualization starts up again, which takes quite a long time. It didn’t do this with firmware 1.6.2. Is there any way to increase the performance of panel so that the panel doesn’t disconnect? Would it help reduce the speed of OPC UA, or something else?
The only thing I had to change was to add the line (Configuration key=“zoom” value=true) to the VIS configuration file, because after the firmware update, sliders started appearing at the bottom and side of the screen.
Thanks for the answer. I’ll try it.
I also don’t understand why firmware version 1.6.2 displayed the visualization normally (without sliders) and version 1.8.0 with sliders on the bottom and right side, when the visualization has the resolution of the display.
First, I slowed down the displayed graph in to 5 seconds in the MappView visualization. This helped when leaving the graph page. It still sometimes disconnected when logging in a user or viewing alarm history.
Then I added line
to the configuration file.
I had to restart the T30 display because it couldn’t connect to the PLC.
It hasn’t disconnected yet, but it’s terribly slow. Sometimes I wait for a response from the display for 2 seconds.
I’m only testing the changes today. So I’ll keep an eye on it.
Note: I still haven’t received a response to the sliders on screen after the firmware update.
T30 is low-performance hardware, so there will always be some compromise between visualization complexity and its responsiveness. However, behavior, from my point of view, should not change after a PPT image update. So please keep us informed regarding the investigation from support. Thanks.
