2.4
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.
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.
*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.
Count/Time
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.
*1 A unit specified in the configuration tool is applied (in seconds or milliseconds).
