Connect Your DH+ PLC5 or SLC PLC to a Modbus RTU Client Device
Now, your legacy Allen-Bradley serial PLC can communicate with a Modbus RTU Client. Connecting a Modbus RTU Client to Serial DH+ PLC makes it the perfect tool for saving legacy PLCs from the scrap pile and extending their useful life.
How Do I Use the 460MRSDHM-D2E in My Application?
Map Modbus register and coil data to files in the PLCs data tables. For example, you can map Modbus register 40200 to N7:200 for reading by your Modbus master. It supports bi-directional data transfer. It really is that simple.
What Is Modbus RTU and What It Can Do for You?
Discover whether a Modbus RTU aligns with your specific needs by visiting our Modbus RTU tech page – Modbus RTU, derived from the client/server architecture, stands as an open serial protocol. Its widespread acceptance in the realm of serial level protocols owes to its ease of use and reliability.

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.
