In this video we show the process needed to connect a Do-more based CPU for remote PLC programming over the Stride SiteLink VPN Cloud. This connection will allow you to remote access the PLC and also program the Do-more PLC remotely.
This setup will work for the BRX PLCs, H2 Based Domore PLCs, and the Terminator based Do-more PLCs.
You will need a Do-more based PLC with ethernet connection, the Do-more Designer software, and a Stride SiteLink VPN router that has been configured. If you have not configured your router, please view the video below that corresponds with your version of router.
Initial setup videos:
In this video we will show the process of getting connected to a Do-more CPU through the Stride Sitelink VPN router. If you have not already setup your router please see the videos for the initial setup, from the links in the description below. Then once you have setup your router continue on to this video. First, we must discuss the Do-more CPUs IP address. This is IP address of the VPN router on the control side. Now, to remotely program your Do-more CPU it must be on the same subnet as the VPN router and have the IP address of the router as it’s Default Gateway. This way the Do-more CPU will be communicating through the router. Now, it is very important that everything is a static IP address, as one limitation of VPN networks is that Broadcast comms will not work and broadcast comms is what is used for auto discovery of devices. So now, let’s set up the Do-More CPU’s IP address for the first time locally. From the Application Launchpad select Net Edit 3. Now select Network and then adapter and verify that you are using the correct Network adapter. Now, click on scan network and you should see your Do-more CPU. Double click on the CPU and enter in the information as we discussed earlier. That will change the IP address of your CPU. Now that the PLC has been setup and shipped to the remote site, let’s make our first connection through the Stride Sitelink. Select your device and then select connect. Once the IX client is connected. Open up the Do-more software and then we will need to make a new Link. So, in the Link section here select New Link…. Select Ethernet and then UDP/IP and then select Next. Now, from the adapter section here, make sure to select the Windows TAPP Adapter. Now Select Link Editor. Select your Do-more CPU type and then select the Port Tab. In the IP address portion place the IP address of your CPU and then select the advanced settings tab. Here you probably need to increase your Timeout time. This is the time that the Link will use to gauge if it has lost communication to the CPU. Increasing this time will overcome long communication time or spotty networks. I typically place this at 15 seconds and then increase if I am having issues connecting. Select Ok. Now I will give the Link a name and then select Accept. Now, I will Read in my project from the Remote Do-more CPU. Now you will be able to program and control you PLC from around the world. A little safety disclaimer though. Before you make any changes to your PLC remotely take into account what you are activating or deactivating remotely as it may cause an unsafe conditions. It is always best to have local eyes on the equipment while making these changes. This is where the digital input on the VPN router can be useful. It will allow you to lock out remote changes until someone is there to monitor to safety purposes If you have any questions about the Stride VPN router please contact AutomationDirect’s support team during regular business hours.
