Running Modbus TCP/IP Server on FIO I am unable to connect to FIO over the network from another computer.
If I use another vendor’s Modbus TCP/IP Server I am able to connect over the network from another computer.
Any ideas?
Hi
I have exactly the same problem …
Please make sure that inbound TCP connections at port 502 (the default Modbus server port) are allowed for Factory IO by any firewall running on the computer.
For Windows Firewall, here is a similar guide on how to do it.
