Posted 10 May 2017 Hello, We recently got a machine with two NS10's. They both connect to the same CJ2H PLC and most of the elements are set using tags. Everything works but the refresh rate when changing screens is really slow. The changed screen displays but it take around 5 - 10 seconds (something like that) before the bit lamps light up and the alarm messages are displayed. Does anyone know what may be causing this? Is it because we have a large number of tags? The NS10's communicate over Ethernet and we have 60 EIP nodes in the machine taking to the PLC at the same time. Perhaps this is the reason? Thanks.

Posted 10 May 2017 I would bet its the network loading but also consider the number of variables used in the HMI. I do not know if the HMI only asks for updates for the variables on the displayed screen, or if it asks for all of the defined variables in the project.
