On the modbus map of the HC900 plc I am putting the analog variable and it goes to the address for example 45063. On the Intouch software I put the 45063 F (f stands for float), and it communicates but only read 0. I am putting the value 1234 on that Analog variable but I only read 0. And it is strange because I do the same thing in a software called Modbus Poll and it works, I can even write on the variable using that software.
