In my Node-red flow, i am taking data from Siemens PLC through OPC-UA node in node-red. I'm getting data perfectly for some-time(meaning whatever changes i make in Tia portal program is also shows in node-red debug window.[Refer to screenshot -1]). But after certain time(2-3 minutes), whatever changes i made at Tia portal program does not reflected back in node-red debug window[Refer to screenshot -2]. I don't know why? Also, OPCUA node status is also changing from "'Active subscribing' to 'keep-alive' to 'active subscribing'..........[Refer to screenshot -3]" I am using * Tia portal[Siemens V16] * PLC sim advanced V2.0 * Node-red(windows 11) * OPCUA contrib node(but not IIOT OPCUA node) Those who need my-node-red flow, i have pasted it here.
