Range of Values per Output Format

This section shows the range of values that can be output for each output format.
Integer type
The ranges of the values that can be represented in each integer type are as follows.
Output format
Word [Signed]
Double Word [Signed]
Word [Unsigned]/Bit String [16-bit]
Double Word [Unsigned]/Bit String [32-bit]
16bit BCD
32bit BCD
If device values or values after scaling exceed the range, they are rounded within the range.
• If the value exceeds the upper limit value, the upper limit value is output.
• If the value is lower than the lower limit value, the lower limit value is output.
Float type
The ranges of the values that can be represented in each float type are as follows.
Output Negative values

*1 -1.79769313486231570E-308 with the report function.
*2 1.79769313486231570E-308 with the report function.
If device values or values after scaling exceed the range, the data is output as follows:
• If the value exceeds the upper limit value of positive value, '+Inf' is output.
• If the value is lower than the lower limit value of negative value, '-Inf' is output.
• For values in a range between the upper limit value of negative value and the lower limit value of positive
value, '0' is output.
Output format
FLOAT [Single Precision]
FLOAT [Double Precision]

The value ranges that can be represented when the output value other than "value" is specified with trigger logging of data
logging are as follows.
