This is Part 8 of our “25 Things to Consider when Choosing an OPC Tunnel” series.  What flexibility is there in how ports are configured?

Depending on your level of knowledge regarding OPC tunneling solutions, you may or may not be aware of how a tunneler uses TCP ports for transferring data between machines.  Your IT department likely gives you plenty of trouble whenever you mention needing to open a TCP port.  And with good reason - cyber attacks frequently exploit commonly used TCP ports.

This blog post will outline three top reasons why it's important for an OPC tunneling solution to support fully configurable TCP ports for transferring your data.

This is Part 7 of our “25 Things to Consider when Choosing an OPC Tunnel” series.  How does the OPC tunneling solution work in a mixed Windows OS environment.

If you have ever used DCOM between two different varieties of Windows operating system (Windows 7 and Windows XP, for instance) you already know how painful it can be to configure DCOM.  DCOM configuration is never a walk in the park but the frustration multiplies when the operating system isn't the same on both machines.

This blog post will outline one of the easiest methods to avoid the problems of configuring DCOM when the operating systems do not match.

This is Part 6 of our “25 Things to Consider when Choosing an OPC Tunnel” series - Configuring a tunneler should be quick and easy.

How easy does the tunneler vendor make it to get started with their solution?  It's important to consider what resources the vendor has made available to you to assist with setup and configuration.  Resources such as videos, FAQs and technical support could mean the difference between your setup taking only minutes to that same setup taking hours or even days.

This blog post will outline some of the expectations you should have from a good tunnel vendor with respect to the resources they can provide to make your experience as user-friendly as possible, both now and in the future.

This is Part 5 of our “25 Things to Consider when Choosing an OPC Tunnel” series. Can your tunneler do more than just tunnel?

Many OPC tunnels out there are just that—an OPC tunnel and nothing more. What if you need to perform another operation with the data besides tunneling it?  In most cases, you'd be stuck introducing an additional piece of software to handle any other operations.

This blog post will outline some of the additional functions you might need from a tunneler and why having a single application is the best architecture.

This is Part 4 of our “25 Things to Consider when Choosing an OPC Tunnel” series. Performance matters when choosing a tunneler.

Performance is always an important consideration when choosing the best tunneler.  It is even more important if one or more of the following is true:

• You need to transfer a lot of data very fast.
• You are using networks with limited bandwidth.
• You are using cellular or satellite networks that charge based on the amount of data used.

This blog post will cover some important aspects to consider when evaluating different tunneling solutions, their methods and the resulting performance relative to such variables.

This is Part 3 of our “25 Things to Consider when Choosing an OPC Tunnel” series. What is the customer experience when contacting the supplier’s technical support?

Technical support is an area where users shouldn’t underestimate the importance.  This blog will cover some important aspects of technical support to consider when evaluating different tunneling suppliers.

This is Part 1 of our “25 Things to Consider when Choosing an OPC Tunnel” series. When choosing software applications to handle the tunneling of your data, there is more to making the right choice than simply a checkbox on a product datasheet that says “tunneling”. This series will introduce you to the considerations that will help you make an informed choice and choose the most effective tunneler for your specific application requirements.
