TOP Server Modbus Plus PCIe-85 Adapater (416NHM30042A) Support
Looking for an IO Server that supports the Modbus Plus PCIe-85 (416NHM30042A) Adapter. Does TOP Server support this adapter? Do I have to make changes to the addressing of the existing Modbus registers?
The Modbus Plus PCIe-85 Adapter (416NHM30042A) is not on the list of officially support adapters, but we have seen successful use by our users with the TOP Server Modbus Plus driver.
Register addressing changes should not be required, thanks to the ability to customize the Data Access and Data Encoding properties for Modbus addressing in the TOP Server Modbus Plus device properties.

We recommend you evaluate the TOP Server Modbus Plus driver with the PCIe-85 adapter before purchasing a license, and reach out to our technical support team if you see any errors or run into any issues. You may do so by emailing support@softwaretoolbox.com or submitting a support ticket.
