I am trying to send the floating point values from a specific device to ABB DCS AC460 controller using RS485 link with Modbus Protocol. The device will send the data in 32 bit IEEE 754 format. It has various options of register format selections like 16 bit Modicon or 32 bit or 16 bit swapped. the device will support Modbus function code 03 and also function code 04. When I send a value say 45.67 to DCS, it reads the value in two 16 bit registers. First register shows 45 and second register shows 0. I tried various register formats mentioned above but still the value shown in DCS is same. Can any one help me in this regard to read the data of the device onto DCS?
