Albert, Looking at the PLY reader in VTK, it looks like it doesn't support custom point fields. I've reported an issue here: https://gitlab.kitware.com/paraview/paraview/issues/18136
If your data is just a collection of points with fields, a simple CSV maybe be easier than PLY. After opening a CSV, you can use the "Table To Points" to interpret the rows as points with fields associated with them. Also, what does a PLC format look like? It may be possible to use a Python programmable filter to directly reader in the PLC without any conversion if the format is simple.
