Application Example: Traditional VPN

Consider two types of OEM machine builders. The first OEM sells very large and complex printing presses with thousands of automation system I/O points, and its customers require the OEM to support the machine, including uptime and throughput guarantees. The OEM needs to remotely monitor and support its presses worldwide to make sure it meets its guarantees to customers. The OEM has considerable IT expertise and is capable of implementing a traditional VPN, and each of the customers is willing to allow the required firewall modifications.

Each press also has multiple video cameras installed for remote viewing, a necessity for solving some of the more complex troubleshooting issues. Each printing press has a full-featured PC-based HMI installed for local viewing and data storage, with high-speed remote access to the HMI and its stored data required at all times. Therefore, large amounts of operating data must be continuously transmitted to the remote corporate control center.

A traditional VPN is the right solution in this application, because of the significant amount of data exchange required, which could be cost prohibitive for a hosted VPN, and because the right IT resources are available to support the solution at the control center and at each site.

Hosted VPN Design Considerations

Those considering this solution must have a high level of trust in the hosted VPN vendor, as it will be responsible for securely storing data and making it available to only those who need it. Monthly costs incurred for high data bandwidth usage must also be considered, particularly as those costs are zero for a traditional VPN solution.

The hosted VPN solution does not require an IT team for support, because it is simple to implement and maintain, and most companies accept it as secure. Those companies that do not accept a hosted VPN solution for security reasons would likely not accept a traditional VPN either because of its required firewall changes.

The simplicity of this solution comes at the cost of limiting some of the advanced routing features that may be required for sophisticated networks, such as machine-to-machine networking, advanced network address translation configuration, and access control lists. However, for most users these advanced features are not required.

Some cloud-based data storage and monitoring solutions allow users to configure dashboards using widgets for remote access viewing on their PC or mobile device. Alerts and notifications can be configured to inform users when parameters fall outside a predefined range. If this feature is not provided, designing remote access viewing screens can be cumbersome.

Traditional VPN Design Considerations

Industrial VPN Router – PLC Remote Access and Data Logging

The main design consideration for this option is the capability and willingness of an IT team to support this solution at both the local and remote sites for each installation. For example, an original equipment manufacturer machine builder must consider every customer site, and make sure all of its customers are willing to provide IT support. If not, the OEM will have to customize its remote access solution for each customer.

This solution is often more expensive up front than a hosted VPN because of increased hardware costs and the IT resources required to configure the connection. Some companies have a dedicated IT staff to provide this support, but many smaller companies do not. Ongoing external costs are lower, because there are no monthly cloud service fees, but internal costs are higher due to the need for IT support.

IT must open an inbound VPN port on the firewall. This provides full remote control and monitoring, as it effectively creates one network joining local and remote users, but also presents a security concern. This port must be protected from unwanted access at all times. Ongoing security vigilance is required to ensure the router and VPN protocols remain up to date, and other technical considerations must also be addressed, including:

Option : Traditional VPN

This option requires a local VPN router to connect through the Internet with a secure VPN tunnel to a second remote VPN router or software client . Once connected, remote users can access automation components connected to the local router through the VPN tunnel.

Unlike option 1, there is no cloud server between the two devices with either method of connection: VPN router to VPN router, or VPN router to VPN software client. This option is preferred when large amounts of data need to be continuously exchanged between the local and remote sites, as to view local video remotely.

This solution is widely used, and it was the only method of secure two-way access before the introduction of cloud-based remote access solutions. It can be complex and costly in terms of internal resources required for support, both at the local and the remote sites.

Funktionality Of Welotec VPN Security Suite

The Welotec VPN Security Suite offers automated processes to roll out and manage VPN infrastructures. It consists of three components. This includes a central VPN Concentrator with integrated Firewall and access rules. An integrated Public Key Infrastructure manages and renews digital certificates. The third component is a Device Management for rollouts and distributing configurations.

Fig. Structure of Welotec VPN Security Suite

The VPN Concentrator bundles the incoming VPN connections, assigns fixed IP adresses and handles routing and NAT.

An integrated PKI automatically creates device-specific certificates. All client VPN certificates are signed by a central authority. In this way, trust is maintained from the end device to the central and parent Certificate Authority or CA for short. Instead of the integrated CA, a users own CA can also be used. It is also possible to connect a users own PKI.

The device management automatically distributes the certificates and VPN configurations. This works with Welotec devices or Docker Container enabled devices, which are connected via VPN Container Client . Welotec devices additionally support template-based management of firmware and device configurations.

How To Implement Secure Remote Access To An Industrial Automation System

Remote access to local programmable logic controllers , human machine interfaces , and other automation system components is becoming a requirement for many machine builders, plants, and facilities. Although many industrial networks were previously configured with a router without a virtual private network , new installations should not do this because of the security risks.

Although a VPN is a key element in a defense-in-depth strategy, implementing remote and secure connectivity to local components presents technical, cost, and resource allocation challenges. The two options presented in this article address these issues in different ways. Each approach has advantages and design considerations . Option 1 is a hosted VPN, and option 2 is a traditional VPN.

The decision to use a hosted VPN versus a traditional VPN hinges on four primary factors:

  • Will all of my remote access needs fall under similar information technology conditions, with each site able to use the same router configurations?
  • Is IT expertise available to support a traditional VPN?
  • Is the IT team willing to support the traditional VPN?
  • Will high bandwidth be required?

As shown in the decision tree , if the answer to any of these questions is “no,” then the hosted VPN solution is likely the best option. When the answers to these four questions are “yes,” then a traditional VPN may be preferred.

many thanks for your response.

I agree with you on the IP address when there is a need to access plc webserver page locally, in other words, CPU and a laptop with a browser are connected to the same network.

I am in a location A and PLC is installed on a remote location B

my question is, regarding the scenario mentioned above, Can I still be able connect to the webserver without using VPN using a unique HTML address associated with the CPU.

I wish I explained better than before



To access S7-1200 web pages, all you need is a web browser, and valid IP address accessible to the browser.

A VPN router could certainly do that if properly configured and networked .


Hi all,

Is it possible to access CPU webserver page remotely without VPN connection ?

Many Thanks

Benefits Of Plc Remote Access For Manufacturing Companies

COVID-19 affected many different businesses in different ways. The manufacturing industry experienced first-hand how the pandemic interrupted their production abilities and business all together. Some have experienced a labor shortage due to illnesses in their staff, others experienced limited operations due to a shortage in resources. Many feared a complete halt on operations which could be detrimental and stressful to any business owner in any industry.

Manufacturing companies are having to use forward thinking in order to put the best practices in place to keep their operations running uninterrupted. This has caused some factories to begin the process of having remote access to their equipment to monitor, troubleshoot and perform maintenance tasks. This ensures that even without having employees on hand, downtime will be minimized or nonexistent.

Having PLC remote access offers secure, fast, and simple remote monitoring capabilities. Its a short-term investment with a quick return rate for most businesses, and many are starting to see the benefits of this transformation. Read more about the benefits below.
