Hey experts,

I am working with 1510sp-1 PN  cpu and KTP 700 basic HMI , in the middle there is a ethernet switch . so I can able to download the program to cpu and the design to HMI as an individual. but the problem is that the HMI doesn't fetch data from plc. plc is ok it send the data in vfd as well. after downloading whenever I start the HMI a "connection disconnected" alarm pop up will appear. when i troubleshoot about it I found that the HMI connection done in the network is fine ,and also there is no issue in the port. but still I am facing that issue.

can you guys please help me to come out from this issue

 Hello,

Can you give more information about the HMI connection?

Hello,

First of all disconnect switch and connect PLC>>HMI straight and see or connection goes from PLC to HMI. If yes then problem will be with switch and you need configure it or in PLC properties check USE Router and enter router address
