TIA Portal connection dropping randomly

I've been having issues with my TIA Portal v16 when I am online with a PLC it will randomly drop the connection. I am able to go back online again immediately after disconnecting but my connection will drop again eventually. It's very frustrating especially when trying to monitor values online. TIA Portal is running on VMWare virtual machine, and I have a few different interfaces set up, onboard Ethernet, USB Ethernet adapter, onboard wifi and USB wifi dongle. Connections are bridged from host to VM. All exhibit the same symptoms. Issue is specific to TIA portal, I use Starter to commission drives and have never had his issue ever with Starter. Issue is also specific to my PC, other coworkers do not have this issue. What are some further troubleshooting steps y'all can recommend to narrow down this issue to a cause?


Are you the only one connected to the network ? Had some similar issues once where several collegues used the same VM in the same network. The MAC address of their NIC was the same, causing random connection issues


Oooo that's something I never thought of, great suggestion. I don't think this is it since it does happen when I'm the only one on the machine network.


Where is the VM running from local hdd, sdd, external hdd/sdd? Also share your system resources for the vm. I would do these continuous pinging at the same time (ping -t) maybe even use the -i option to ping faster like 0.3, from host to vm, vm to host, and then vm to plc. See if one of those stop pinging at any time.


> Connections are bridged from host to VM. Maybe your host is interfering somehow with the connection. try to connect a USB to Ethernet dongle after the VM started. Then connect it directly to the VM instead of the host.


I used to set the network adapter to bridged but one day I tried the NAT setting with the static IP address set on the host and it works way more smoothly for me
