Description
338
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, the content of CIO 0001 will be output to D00110.
If the binary content of CIO 0001 is greater than the content of D00101, the
content of D00101 will be output to D00110.
If the binary content of CIO 0001 is less than the content of D00100, the con-
tent of D00100 will be output to D00110.

Operand Data Areas
S: Input word
S C D
C: First limit word
D: Output word
When the execution condition is OFF, BAND(272) is not executed. When the ex-
ecution condition is ON, BAND(272) controls output data according to whether
or not the specified input data (signed 16-bit binary) is within the upper and lower
limits (dead band). The contents of words C and C+1 are as follows:
C
C+1
If the input data (S) is less than the lower limit (C), the difference between the
input data minus the lower limit data will be output to D and the Less Than Flag
(A50007) will turn ON.
If the input data (S) is greater than the upper limit (C+1), the difference between
the input data minus the upper limit data will be output to D and the Greater Than
Flag (A50005) will turn ON.
