I knew ModSim32 as a client, not as a server. But it seems, that is a server... Address 40001 is absolute modbus address 0, 40002 is absolute modbus address 1 and so on. 4000x are the address area in the application layer, but the modbus block don't use the application layer, but the absolute addresses.
