I'm really new into node-red.
I installed the program and the add-ons for modbus tcp.
I config my server master (Tbox/servelec) with its IP address: OK
I defined some readings: int16 block of 10 consecutive addresses, some single float registers with their conversion function, etc : OK
OK in fact when I poll every 15 seconds, my polls are working and the results are displayed as expected. But this it too fast, I don't need those fast readings (temperature mostly).
When I lower the polls to 1 per 15 minutes, I obtain a socket error / econnrefused. If I change the poll for 1 per 15 seconds and restart the flows, all is OK again.
Question 2: When my polls are OK (1 per 15 sec), when I try to add a node with another modbus unit (also TCP, different IP address), same problem.
Maybe a network problem or some unknown (to me) collisions ?
Thank you for your help
