Hi,
We are trying to read a float 4 byte temperature point from a modbus tcp device. We can read via other modbus plc's like 32, 11 degree.
But when we use LM we are getting high byte and low byte from different registers. Our temperature registers are 0 , 2, 4. But we are getting values from both 0 and 1.
Example :
Register 0 : 16896
Register 1 : 30915
We realized that those are high and low byte of our 4 byte point. If we combine them as a float manually in excel, it's : 3,2117931E+01 and that is our temperature.
In our profile , point type float32 and point type register.
What we can do ? How we can read as a single point ?
Regards,
