polling modbus registers as signed or unsigned doubles or reals

[xrayguts]

Hey quick question. I am currently polling data from a ScadaPack 100 plc. I am using the Modbus serial driver. I am polling unsigned values and it works great. Boolean and unsigned no problem.. my question is how can I poll a real number. ive looked through the threads it may be something im over looking. I apologize if this has already bean covered

A floating point number can be read by preceding the address with an F, for example F40001 will read 4 bytes and return it as a floating point value.
