I think you can read the Modbus mappings from REF542plus with the Modbus Suite tool. This tool should come with the REF542plus Configuration Tool.
You can find information about the Modbus Suite in the later part of the Modbus Technical Reference manual: https://search-ext.abb.com/library/Download.aspx?DocumentID=1MRS755868&Lang
