Bad too many connection error #672

frankTopspin commented 4 months ago

Hi, I'm a newbie in using this plugin. I've made some nodered flows to read/write some data from an OPC UA server (panasonic PLC). Everything goes well, but something some crash occurs. When i try to relaunch nodered I give the message (from nodered debug) too many bad connections. I've to relaunch nodered or restart machine more times to get it working again. What can I do to fix this delay? Sorry for my english. Thanks

Use less client nodes, you cn use just one and inject action it will overwrite select action.

Hi mikakaraila, there are any news about that? There is a way to send multiple requests with the same connection without use multiple read? What do you mean about "you cn use just one and inject action it will overwrite select action?" What is the best practice to do that activity? Can you give us some hints or some short example code? Thank you very much! Frank
