AC500 modbus FCT23
I cant figure out how to use the funcion 23 in the COM_MOD_MAST block.
I have a PM573-ETH CPU and want to use a READ/Write sequence in modbus to comunicate with DCS800 drives.
I have no problems using Function 3 and 16 for read and write, but i will be much useful if i can use a read/write fuction.
Anybody knows how to use funcion 23 and has an example project?
