Connect Your DF1 PLC5, SLC, or MicroLogix 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 460MRSDFM 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 client. Bi-directional data transfer is supported.
It really is that simple.
Why Use Real Time Automation as a Gateway Supplier?
While there are certainly a number of other companies offering 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.
