M580 Max Input Real/Float Value

[gokul1990]

Does anyone know what is the Floating/Real Value range for M580 Modi con Input.

As far as i know 3.402E+38 is max

1. I am trying to use a totalizer block and when i pass Max real to Input it goes to Infinity 1#INF

2. Could you suggest some Min Positive real value for Modi con M580 Input

Yes, IEEE max float is 3.4028235e38.

But what are you trying to do?  Why would you pass 3.402E+38 to the input of totaliser?  Or am I mis-understanding?  If the totaliser itself is accumulating up to 3.402E+38, then you should consider using more appropriate engineering units on the input.  And don't forget to set a suitable Threshold parameter (I usually just use 10000).

If you do need to have very large numbers, you would be better doing a smaller accumulation and then incrementing a UDINT (using appropriate engineering units).
