Having connected to a PLC via VM Ware without issues in the past, I am facing challenges with a specific machine. Utilizing Windows 7 on a Windows 10 device to communicate with the PLC, I have encountered difficulties. Despite being new to this position and inheriting the previous laptop, I am unable to access any devices connected to the PLC's Ethernet port, all showing red X's. Attempts to ping the PLC IP address using VM Ware result in a "Destination host unavailable" message, whereas successful pinging is achieved through the host machine. Despite confirming compatibility of the Windows 7 IP address, the issue persists. Is there a potential barrier or inactive settings causing this problem? Would obtaining an older Windows 7 machine be a more effective solution?
Do you have an Ethernet-USB dongle or are you utilizing a VMware virtual adapter? Port issues could be caused by the Windows firewall. If you are unsure about the connection to VMware (VMware or the main Windows system), check if your virtual network is set to bridged or NAT. Using USB adapters ensures a direct connection to the Ethernet port for seamless VMware connectivity.
When setting up a VM, it's important to note that the machine's IP address will be separate from your host PC's. In the VM settings, make sure to select "Bridged" under Network Adapter and enable "Replicate physical network connection state." This configuration can help streamline network connectivity.
For an extended period, I have utilized VMWare virtual machines with dual network adapters configured. One adapter is designated as "Host-only" for licensing purposes, while the other operates on NAT. Both adapters are set to utilize DHCP for seamless management by VMWare. To connect to my workplace's LAN, I make use of a USB Ethernet adapter on the host machine with a static IP address within the appropriate subnet for the PLC, which has proven to be mostly trouble-free. Additionally, I have a Wi-Fi adapter on my laptop for remote connections to the company LAN and a wired NIC on my docking station for office LAN connectivity while at my desk. The USB NIC is dedicated to my testing setup at the desk. Initially, I used Bridged connections in the VMs, but with the growing number of VMs and laptops, it became cumbersome to assign individual IP addresses. Switching to NAT proved to be a more efficient solution. There are specific scenarios where I directly connect the USB adapter to the VM: 1) When I need to utilize BOOT/P to configure a device's IP address, and the process is unsuccessful from the host. By temporarily disabling the NAT and Host-only adapters in the VM, I can solely rely on the USB NIC instead of sharing the host NICs for other tasks. 2) At a previous job, some machines arrived with IP addresses in the 169.x.x.x range, a sign of DHCP failure in Windows. Due to VMWare's limitation in routing these addresses from the host to the VM, I had to directly attach the USB NIC to the VM for proper connectivity.
Is the Virtual Machine configured for NAT mode?
A simple and effective troubleshooting method involves accessing the command prompt and running the ipconfig command. This command will provide you with the IP address of the network device within the virtual machine, ideally within the same subnet as the PLC you are attempting to establish a connection with.
It sounds like this could be an issue with the virtual network settings on your VM Ware. I would start by checking if the VM's network adapter is set to "Bridged" mode. This should allow your VM to directly connect to the local network the host is on, eliminating any potential networking issues that might be causing your PLC communication challenges. Furthermore, make sure the firewall settings on your VM Ware aren't blocking the necessary ports. Swapping to an older machine might not necessarily resolve the problem, especially if it's a network settings issue.
Rather than jumping to a different machine operating on Windows 7, we can start troubleshooting existing settings. A possibility is that your VMWare's network interface is not set up in "bridged" mode. This mode communicates directly with your physical Ethernet adapter and is crucial if your PLC and PC are on identical networks. Moreover, ensure your firewall settings inside Windows 7 are allowing incoming and outgoing traffic from VM to the PLC. Another point is to check if there are any IP conflicts with other devices on your network, as that could cause such issues. If these aspects are already configured correctly, sharing your VM network settings would help in providing a more in-depth troubleshooting approach.
From your description, it sounds like there might be a network issue between the PLC and the VM Ware instance. As you're able to ping the PLC from the host machine, I'd suggest checking your VM's network settings. It should be set to 'Bridged Mode' so it will act like it's on the same network as the host. If that's not the case or if it's set to NAT or some other network mode, it could be the root cause of the problem. As for grabbing an old Windows 7 machine, while it could potentially be a quick fix, addressing the network issue is a more sustainable and practical solution moving forward.
I don't think you necessarily need to invest in an older Windows 7 machine. From the sound of it, it seems like a communication issue between the VM Ware and the PLC. It's possible that the network settings on the VM Ware are not correctly configured. One thing you could try is checking the network adapter settings of the VM Ware. Ensure it is set to 'Bridged' and replicating the host's IP addressing. Also, your firewall settings might be playing a part here, so try temporarily disabling them and see if that helps. However, raising this issue with your IT support might be beneficial; they could have encountered similar problems previously and could direct you to a more precise solution.
It sounds like you might be dealing with a network configuration issue between the VM and the PLC. Have you checked the VM's network settings? Sometimes switching the adapter type to "Bridged" instead of "NAT" can help establish a direct connection with devices on the same network. Also, make sure that the Windows Firewall on your Windows 7 VM isn’t blocking the communication. If those settings look good and the problem persists, it could be worth testing the setup on an older Windows 7 machine to eliminate any potential compatibility issues, but I’d try to troubleshoot the current setup first — it might just need a few tweaks!
It sounds like you've got a tricky situation on your hands! Since you're able to ping the PLC from the host machine but not from the VM, it could be a networking issue with the VM's adapter settings. Make sure the VM is set to use "Bridged" networking instead of "NAT" or "Host-only," which might be blocking the communication. Additionally, check if the Windows 7 firewall settings are too restrictive or if there are any specific drivers or network configurations needed for the Ethernet connection on that PLC. If you’re still stuck, using an older Windows 7 machine might be a good fallback for testing, but first, try adjusting those VM network settings to see if that clears things up. Good luck!
