Modbus address detecting problem
Am planning to use AC500 PM573-ETH with ESA HMI VT-555. Communication through Modbus. But problem is word address. AC500 is not accepting %MW1.0. It will accept %MW0.16. While in ESA HMI word address range is %MW0.0 to 0.15, Again we can select %1.0 to 1.15. So pl guide me how to solve this

In AC500 Modbus addresses are:
%MW0.0 to %MW0.32767 which is equal to Modbus addresses 0 to 32767 DEC.
%MW1.0 to %MW1.32767 which is equal to Modbuss addresses 32768 to 65535 DEC.
I don't see why you can't use them

Communication error while downloading programming to PM573ETH using TK503 cable. I have selected PM581 for PM573. Its as per ABB manual.
