hi tested - 4 packets transmitted, 0 packets received, 100% packet loss. Both, LM and other device i can access via http. Do you have a clue?

what IP settings are on LM and on your Modbus tcp device (IP, Netmask, Gateway)

LM:                   192.168.1.3, 255.255.255.0, 192.168.1.1
Modbus device : 192.168.1.4, 255.255.255.0, 192.168.1.1


Same subnet. Both devices are reachable from my PC, and ping works 100%.
