Support Questions / How to Avoid PLC and PC timeouts
« on: February 28, 2024, 03:28:51 PM »
Hello,
I am using advancedhmi v35 and visual studio 2022, I wrote a VB.net script to continuously monitor data on the PLC (a GuardLogix 5380 Safety Controller). It works very well, but we run into an issue where the line will go on break for lunch etc and during that time the HMI says it has lost connection to the PLC. I am connected through an EhternetIPforCLXCom connection, I even setup a counter function that continuously runs to keep the EthernetIPforCLXCom1_DataReceived sub active; however, it still times out and when the line is started back the HMI never reconnects. Is there a better way to perform a handshake to allow the PC and PLC to not lose the connection between the two?
I though about creating a section on the PC that will reset the counter when it reaches a certain level. Any advice would be greatly appreciated.
