Hello,
I am building a PC based HMI system that utilizes a DL06 PLC and it has the H0-ECOM ethernet card installed. I have the PLC setup and I can send UDP packets to it, but I can't connect to it via TCP through the Java application. I am trying to connect via a socket and was kind of expecting that there is listening TCP port (28784) on the ECOM card but for some reason its not working. I have checked my firewall and allow both tcp and udp 28784.
What else am I missing? I appreciate your responses.
