Hello all and a merry Christmas.
I have a question for the forum. I have 10 Siemens PLC's talking in a ring main fibre optics rugged com and with two of the PLC,s are in turn connected to their own comfort 900 HMi. If I plug into lets say the PLC connected to the HMI I can go online to all including the HMi's.
The tia portal laptop has to go through a firewall that I have to configure for security reasons from my client. I have programmed all the IP addresses into the Firewall (Checkpoint security) and I am able to go online to any PLC but not the HMI. Remember the HMI is not connected to the ring main but straight to the PLC. The protocol I have allowed is ICCP is there any suggestions as to why I can't reach the HMI's through the firewall, What other protocol should I allow?:scratch I have allowed the rugged com, PLC's and HMI's IP addresses. Its got to be firewall setting that I am missing but what?
