Full Version: Modbus TCPIP communication with UMAC

I build up Modbus TCPIP communication with UMAC successfully, for the coil and discrete read/write , it is worked normally. and for the registers read/write, it seems that only 16-bit registers can worked normally. because of bit 16 to 23 for X:memory and Y:memory are not used, if I define a register which bits is larger than 23 bits, the data received is wrong. and if I define a register which is a float type value, It can't receive data.
M2040->L:$107A4 //pointer to 48 bits value.
M2041->F:$107A5 //pointer to float type value.

so is there any solutions to avoid this issue? read/write values which bits is larger than 23 bits, and read/write float values correctly.
