I have an Allen-Bradley CompactLogix PLC, on the LAN side of a Flexy 205.
The Flexy 205 is connected to the internet. I can connect to the PLC using Talk2M
I have an HMI at another location also connected to the internet
I have made the Flexy’s Cellular IP address visible, and I can ping the unit from the HMI PC.
The HMI needs to be able to read data from the PLC, send commands to the PLC, without using Talk2M.
I was told this is possible, but thus far, setting up a proxy and redirecting traffic on Port 44818 has not worked. Looking for suggestions.
If Necessary, I can connect the HMI to the internet using another Flexy w/ Verizon cellular.
