7. In the
Size
attribute box, select either
16 bits
or
32 bits
.
8. The
Int. Number
and
Dec. Number
attribute boxes are used to specify the number of digits you want
displayed before/after a decimal point. For example, if you are writing to a 16-bit PLC register using
unsigned format and have Int.Number =3 and Dec.Number =2, then the BLU300 will allow you to
write a five digit number with the three leftmost digits placed to the left of a decimal point and the two
rightmost digits placed to the right of the decimal point.
*
If the value read in the PLC register requires more digits than you have allocated with the Int.
Number and Dec. Number, the HMI will display only the specified digits. For example, if the
value in the PLC register is +17,220 and Int.Number = 2 and Dec. Number = 1, then the HMI
will d22.0 giving no indication that the actual value in the PLC register is larger.
Therefore, it is the responsibility of the HMI programmer to ensure the HMI settings are correct
for the PLC range to be used.
