Connect Modbus RTU Servers to an EtherNet/IP PLC

Connect Legacy Modbus RTU devices to EtherNet/IP Controls





The Smart Way To Move Modbus RTU Registers and Coils To an EtherNet/IP Client

The 460ESMM connects up to 32 Modbus RTU servers to an EtherNet/IP controller. It’s the perfect tool to save legacy Modbus RTU devices from the scrap pile and give you the ability to utilize the huge variety of Modbus RTU devices available in your EtherNet/IP architectures.

How Do I Use the 460ESMM in My Application?

For Most applications, you can map the data very straightforwardly. You map Modbus Register and Coil data to EtherNet/IP IO data blocks. You map EtherNet/IP data directly to your Modbus RTU Servers. Move up to 480 bytes of data in each direction between Modbus RTU and EtherNet/IP. It really is that simple.

Why Use Real Time Automation as a Gateway Supplier?

The 460ESMM provides an option to connect Modbus RTU Servers to an EtherNet/IP Scanner device. While certainly other companies offer stand-alone gateways, no one provides the level of support and service that you receive from RTA.

When you call, a live person answers the phone. If you speak with sales, you receive honest answers and recommendations, even if that means recommending someone else’s solution. When you get support, it comes from an engineer who had a hand in the product’s development, and support doesn’t require a ticket or 24-hour wait. We are unashamed of the fact that we are a smaller company because that means you mean a lot more to us.

What our Customers are Saying

“I challenged a customer to get it working by the time I got back from his break room with a Coke and he indeed had it working when I got back. He then said, "It’s worth twice the price!"”

Eric P. / Kendall Electric

“Everything seems to be working as we imagined. Thanks for the great response time. I did not see any way to save the configuration other than screen shots, but the configuration did not get lost in the update. Thanks again, and you were a pleasure to work with.”
