I have configured a Cisco switch, and it communicates well. I can go online with the PLC and see all public and private IP address devices showing as communicated. I checked the private BK input block IOs that turn on/off physically as well as logically, and it is working, which means everything is communicating properly.
I also tried to ping the public devices connected to the switch through the Cisco switch, and it works. However, when I tried to ping the private devices, there was an issue. I even tried setting the laptop IP address in series with that, i.e., 192.168.1.253, and added the RSLinks configured driver IP address, but I am still not able to ping.
