GE Fanuc %R00001 corresponds to Modbus 40000.
GE Fanuc %AI0001 corresponds to Modbus 30000.
GE Fanuc %I00001 corresponds to Modbus 10000.
GE Fanuc %Q00001 corresponds to Modbus 00000.
Any other GE Fanuc memory types have to be moved into one of the above four to be accessible via Modbus RTU. Remember that the RTU protocol won't let you write to 1xxxx or 3xxxx memory.
