Numerical Calculation
Data Bit
Sets the data length for when you will output numerical calculation results using
parallel output. Select 8, 16 or 32 bits in accordance with the range of numerical
values that you will output. However, it is only possible to set one data length for
the four registers that are displayed at one time (e.g. if CA01 to CA04 are displayed,
it is not possible to set CA01 to 8 bits and CA02 to 16 bits).
The ranges that can be handled by the different data−bit sizes are as follows:
8−bit: 0 to 255
16−bit: 0 to 65535
32−bit: –2147483648 to 2147483647.
External output registers that are not set are skipped during output.
