I have a 4g Flexy 205 using a verizon sim, which is supposed to talk to a 1769-L33ERMS safety controller. When the PLC is connected to any LAN port on the flexy, the entire LAN network craps out. When we unplug the PLC, comms to other devices on the network are restored. Initially the connection was just so slow it literally took an hour for a 20 rung routine to open while online, however comms with the rest of the devices on the network were great and we could even ping the PLC with a very fast 150 ms response. After exhausting all other options we tried setting the gateway address on the PLC to the address of the Flexy. This caused the Flexy to just stop talking. Even the VPN connection was broken. Not even comms to the other devices which we had a connection to. Now with the PLC unplugged we can talk to the other devices, but once the PLC is plugged back in, the whole network crashes. Total Memory in the processor is 2,097,152 bytes Used: 644,048 Available: 1,453,104. Could the memory which RSLinx uses be an issue? Any ideas? Anyone?????
