Data ranges which can be handled in the PLC
Binary data which can be handled by programmable controllers are:
16-bit binary data: K-32768 to K32767
32-bit binary data: K-2147483648 to K2147483647
BCD code which can be handled by programmable controllers are:
16-bit (4-digit BCD H code): H0 to H9999
32-bit (8-digit BCD H code): H0 to H99999999
If any of the above ranges are exceeded when processing the corresponding data,
overflow or underflow will result.
BCD is an acronym for binary coded decimal and refers to expressing each digit of a
decimal number by four binary digits.
Example: When the decimal number is expressed in BCD
