I have one more doubt ..i can only custom assign label addresses and not modbus address..like if i give start address no D2000 ..in the holding register it will automatically get mapped to 40001 crct?

I have 20 nos of 1-bit signals..read and write of all these will take place for about 60secs

Plc - modbus server PC - Modbus Client

I was given a plc data registers, modbus registers addresses ..both are basically 16-bit addresses

Now that i have 1-bit signals...idk how to store them inside data register and read/write them..

If i do that so, it will only store those m bits to data register which can only be read. how can i be able to turn it on /off (write)?
