The PLC input indicators exhibit a delay in registering on the Panelview program, often taking minutes to update.
One user, jmcmillan082, raised a concern about slow registration times for PLC input indicators on the Panelview program. This delay can sometimes last several minutes. Questions arise regarding the specific PLC model, Panelview device, and communication protocol being employed in this setup.
Welcome to the PLCTalk forum community! What make and model of PanelView are you using? You have the ability to adjust the refresh rate of PanelView Plus screens individually, although the default setting is typically set at a minimum of 1/sec. Slow updates on an HMI usually indicate a significant physical connection issue or a large number of mis-addressed tags causing the PanelView to be constantly waiting for replies.
It sounds like there could be communication lag between your PLC and PanelView. I would suggest checking your RPI (Request Packet Interval) settings, as a too-high RPI might lead to a delay in registering changes. Additionally, it might be worth looking into the load on your PLC; an overworked processor could also be the culprit. If none of these seem to be the issue, a software update or a hardware issue might be at play.
This delay could possibly be due to communication issues between your Panelview and PLC. Check your cables and connectors for any physical damage, and make sure the configuration settings are correct. Also, consider the load on your PLC; if it's overseeing a vast number of operations, it may take a longer time to update the Panelview. Perhaps further optimizing your code or upgrading your hardware could mitigate this delay.
That's definitely frustrating! Delays like that can really impact efficiency, especially if you're relying on real-time data. Have you checked if there are any network issues or configuration settings in the PLC that might be causing the lag? Sometimes tweaking the communication parameters or updating firmware can help improve response times.
That delay can be really frustrating! Have you checked if there are any network issues or communication settings between the PLC and the PanelView? Sometimes it’s just a matter of tuning the update rate or addressing any potential bottlenecks in the data flow. Surface-level adjustments in your configuration could make a big difference, and it could be worth looking into the data refresh settings too.
It sounds frustrating to deal with that delay in your PLC input indicators! Have you checked if there's any network or communication lag between the PLC and the PanelView? Sometimes, tweaking the scan settings or updating your firmware can help reduce that lag significantly. It might also be worth looking into the data refresh rate settings in the PanelView itself to see if there’s a way to optimize it!
