I can transfer files in and out of our IRC5 controller via service port (using Robot Studio), but have been unable to connect via plant internal network (although I can ping the address(es). Robot Studio docs state that additional software (PC Interface option) was required (which amounted to a custom OS that must be installed).
Filezilla complains: Connection attempt failed with "ECONNREFUSED - Connection refused by server". Perhaps our communication is mis-configured. I found the address set up in Ethernet/IP Anybus network. Could someone provide an example of a working system?
