CompactHMI real data type decimals of PLC variable

Hello,

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?

Thank you.

This is a known issue with PLC Connect and SoftPoint Server. Please refer below screenshot from System Version 6.0.3.2 Release Notes; Known Issues section.

You will notice the same behavior with Signal_Real8.

So, you will have to live with this behavior. :(
