Connect Your DH+ PLC5 or SLC PLC to a Modbus RTU Client Device
Your legacy Allen-Bradley serial PLC can now communicate with a Modbus RTU Client. It’s the perfect tool to save legacy PLCs from the scrap pile and extend their useful life.
How Do I Use the 460MRSDHM-D2E in My Application?
Modbus register and coil data is mapped to files in the PLCs data tables. For example, you can map N7:200 to Modbus register 40200 to be read by your Modbus master. Bi-directional data transfer is supported. It really is that simple.
Why Use Real Time Automation as a Gateway Supplier?
While there are certainly other companies offering protocol gateways, there is no one who provides the level of support and service that you receive from RTA. When you call, a live person answers the phone. When you talk with sales, you will get honest answers and recommendations. When you get support, it is from an engineer who had a hand in the product’s development, and support doesn’t require a ticket or 24-hour wait.

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.”
Kevin L. / Extol, Inc.
