Product Description
Connect Up To 32 Modbus RTU Slave Devices to a Serial PLC5, SLC or MicroLogix PLC
You can now connect a network of up to 32 Modbus RTU slaves to a legacy Allen-Bradley PLC over DF1.
It’s the perfect tool to save legacy PLCs from the scrap pile and extend their useful life.
How Do I Use the 460MMDFM in My Application?
The mapping is very straight forward. Modbus register and coil data is mapped to files in the PLC’s data tables. For example, you can map N7:200 to Modbus register 40200 in Modbus Slave 10. Data transfer is bidirectional.
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.
