Inputting Numeric Values
Reference: When the Storage Type is BCD, the numeral memory table’s signed binary data
is converted to data for storage in the host word (BCD data) and written to the
host. If the value is negative the most significant digit in the word is set as F. This
means that the maximum number of digits for a negative number (integer part +
decimal fraction part) is seven.
When the Storage Type is Binary, the contents of the numeral memory table are
written without alteration to the host word.
However, when a negative number is written to a numeral memory table whose
number of allocated words at the host is one, it is stored immediately after input
as a 16-bit negative number.
The data is stored in the numeral memory table as a 32-bit negative number in
this case as well.
Upper/Lower (Max./Min.) Limit Check
The PT has a function to check the correctness of an input numeric value to pre-
vent a numeric value outside the allowable range from being input so that the
input of an illegal value will not adversely affect the system.
