CodeSys access to Epic USB Serial Ports

Has anyone tried access to the USB Serial ports on the Epic from CodeSys? What port numbers would they be?

I have a 4 channel Serial IO Module plugged into the 1st slot and working fine, but have no other available slots for a 5th and 6th serial port, which I need.

Here is a screen shot from Epic groovManage with 1 serial USB adapter plugged in. All 5 ports are listed as Devices, but only 4 as CodeSys ports.

Unfortunately, at this time the groov EPIC does not have support in Codesys for the USB to serial adapters.

One idea may be to use Node Red, and get the serial data in, then you could use the OPC-UA Nodes, and push the data into Codesys.
