Display Resolution of REAL and LREAL Number in PLCnext Engineering

All:

 

If I divide 2xREAL or 2xLREAL numbers and Put the Value into another REAL, the Output of that Calculation only displays 2 Decimal Places of Resolution:

        e.g. In PLCnext...REAL#1000.0 / REAL#23.45 = 42.64             using A Calculator, Yields 42.6439232.....

        If, in the PLC Program, I take that Output and Multiply * REAL#1000.0 = 42643.92

I can see that the PLCnext DOES use more than two decimal places (the above shows that it holds at least 5 decimal places)

 

I am Hoping that you possibly add a feature that will allow me to 'SEE' or 'DISPLAY' more than the Default of '2' Decimal Places ?

It would be nice to add a feature that will allow me to select Number of Displayed Decimal Places for REAL/LREAL 

(I would like 5 or 6 Decimal Places, but at least 4 Decimal Places are needed)

On very small measurements or scaling... Troubleshooting and precision is important, as we need to detect small measurements and our resolution is not quite big enough to tell if it is working or not.

Thank you

 

Regards,

Peter

    Hi Peter,

    If you are referring to the number of decimal places displayed in PLCnext Engineer in Debug mode, then this can be changed from the Extras -> Options menu item, and selecting "Online Values".

    Hope this helps.
