Modbus TCP Reading Float Values

[brandon21]

Hi, I'm new to the software and just getting used to working with modbus as well.  I'm trying to read multiple floats into my program on a Yaskawa Servo Drive.  When I use INT I have no problem but when I change to floats it acts up. Does it make sense that under the PLCAddress for the BasicLabel the order I'm going in is: F40001, F40002, F40003. If I enter a number in at the F40001 register it changes the F40002 register as well and then vice versa.  Wondering if this is something in this software I can fix or something in my programming software.  Thanks in advance.

F values are 32-bit and stored in two 16-bit registers.

Also, try using these apps for the sake of practicing as well as confirming what values you should see in the registers:
