If the minimum value of the deadband in S
instruction is not executed.
2. Only the 32-bit instructions can use the 32-bit counter, but not the device E.
3. The following graphs show how this instruction uses the deadband.
BAND is not exec uted.
Output value
4. The minimum value of the deadband in S
the output value in D must be within the range described below.
5. For the BAND instruction, the minimum value of the deadband in S
the input value in S , and the output value in D must be between -32768 to 32767. Suppose the minimum value of
3
the deadband in S is 10 and the maximum value of the deadband in S
1
output value in D as follows.
Output value in D = -32768-10=16#8000-16#000A=16#7FF6=32758
6. For the DBAND instruction, the minimum value of the deadband in S
the input value in S , and the output value in D must be between -2147483648 to 2147483647. Suppose the
3
minimum value of the deadband in (S
2147483648. The instruction calculates the output value in (D+1, D) as follows.
Output value in (D+1, D)
=-2147483648-1000=16#80000000-16#000003E8=16#7FFFFC18
