(2) Outputting numeric values externally from the CPU module
When externally displaying numeric values operated in the CPU module, a digital indicator can be used.
(a) Outputting numeric values
The CPU module performs program operations in binary.
If the binary values used in the CPU module are output to a digital indicator, the indicator does not show the
values correctly.
To convert the data set in binary into binary-coded decimal, which can be used in the external indicator, use the
BCD instruction.
The BCD instruction allows the external indicator to display values in decimal.
