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.
