Uploading the program from a Compact A984-131 PLC using Concept returns 'Illegal address or address range for Modbus program command (Error Id: OL9-1592)'.

The reason this occurs is because only Modsoft, ProWORX 32 or ProWORX NxT can be used to transfer an application to or from the Compact A984-131 PLC.
