URSim MODBUS values default to 65535?

I’m working on a URCap that will write values to MODBUS registers, but it’s very difficult to test because the value of every modbus register in the URSim gets locked to 65535. If I enter another value on the installation page, it appears in the box momentarily, but then changes back to 65535. I don’t know if this is an expected behavior or a bug, but how can I make the URSim stop overwriting these modbus values?


Changing the modbus register was not available on URSIM when I tried…
But I hope that 502 port of URSim is available for debugging the program.
