CompactHMI real data type decimals of PLC variable
I have a problem with PLC real data type variable decimals in CompactHMI. Real variable value with more than 2 decimals doesn’t have same value in PLC and in HMI, e.g. PLC_value=8.5051 and same variable HMI_value=8.5078. In HMI I am using data type PLC_Real4.
I would appreciate if someone could tell me is this problem about wrong HMI data type selection or some configuration error in signal / HMI object?
