When CIO 000000 turns ON in the following example, one of the following will
occur:
• If the binary content of CIO 0001 is within the range specified by the content of
D00100 and D00101, 0000 will be output to D00110.
• If the binary content of CIO 0001 is greater than the content of D00101, the
result of (CIO 0001 minus D00101) will be output to D00110.
• If the binary content of CIO 0001 is less than the content of D00100, the result
of (CIO 0001 minus D00100) will be output to D00110.

Operand Data Areas
S: Input word
S C D
C: First bias word
D: Output word
When the execution condition is OFF, ZONE(273) is not executed. When the ex-
ecution condition is ON, ZONE(273) adds the specified bias to the specified in-
put data (signed 16-bit binary) and places the result in a specified word. The con-
tents of words C and C+1 are as follows:
C
C+1
If the input data (S) is less than zero, the input data plus the negative bias will be
output to D and the Less Than Flag (A50007) will turn ON.
The upper limit setting is less than the lower limit.
The content of a*DM word is not BCD when set for BCD.
The input data (S) is greater than the upper limit (C+1).
The output data is all zeros.
The input data (S) is less than the lower limit (C).
The output data is a negative number.
