PROTOCOL GATEWAYS
Real Time Automation (RTA) industrial protocol gateways are hardware modules that translate data from one protocol to another. Sitting between industrial networks, they bridge communication from otherwise incompatible devices while offloading protocol management from PLCs, lowering CPU overhead and ensuring logic stays focused on process control. With over 4,000 protocol conversion solutions, RTA moves your automation data where you want it, when you want it and how you want it. The hardest part of using RTA protocol gateways is opening the box.

Protocol Gateway FAQs
Protocol gateways translate data from one protocol to another. Sitting between industrial networks, they bridge communication from otherwise incompatible devices and networks.
Why use a Swiss Army knife when all you need is a butter knife? One-to-one protocol gateways, like RTA gateways, provide simple, one-to-one protocol conversion that eliminates the configuration complexity and premium pricing of competing multi-protocol gateways. Our belief is that you should only pay for the protocols you need instead of overpaying for the dozens of protocols you never will.
Protocol gateways allow controllers and devices leveraging different industrial protocols to communicate with one another, enabling factories to seamlessly integrate legacy and modern control networks. Protocol gateways are preferred over custom logic and other proprietary modules because they offload protocol management from PLCs, lowering CPU overhead and ensuring logic stays focused on process control.
Hardware-based protocol gateways do not require manufacturers to write complex ladder logic or custom drivers, download proprietary software or pay ongoing licensing or subscription fees. The gateway handles all protocol conversion, data transformations and transaction triggering, delivering clean, usable data directly to PLC data tables.

What Our Customers Are Saying
I tried for several months to find someone who knew the older Allen-Bradley RB modules…. After almost a year of searching for help, RTA fixed our problem in a few short weeks.
You guys have developed a great line of products. Easy to configure, easy to use. And if I’m in doubt, you are always there to answer quickly.
All of us here are very big fans of RTA. It’s fantastic that we can count on a great product that works and comes with the best support.
I have been using RTA modules for the last four years and I have been extremely happy with their products and support. I really feel that this is one of the best industrial gateway devices in the industrial realm.
