Product Description
Make Your Serial PLC5, SLC or MicroLogix PLC Act Like a Modbus TCP Device
Your legacy Allen-Bradley serial PLC can now be a connected to a Modbus TCP Client Device.
It’s the perfect tool to keep those old legacy PLCs from the scrap pile and extend their useful.
How Do I Use the 460MSDFM in My Application?
For most applications 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 Server 10.
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.
