3. Only the 32-bit instructions can use the 32-bit counter but not the device E.
4. The negative deviation in S
within the range described below.

For the ZONE instruction, the negative deviation in S
the output value in D must be between -32768 to 32767. Suppose the negative deviation in S
the input value in S
Output value in D=(-32768)+(-100)=16#8000+16#FF9C=16#7F9C=32668

For the DZONE instruction, the negative deviation in S
and the output value in D must be between -2147483648 to 2147483647. Suppose the negative deviation in
(S +1, S ) is -1000 and the input value in (S
1 1
value in (D+1, D) as follows.
Output value in (D+1, D)
=-2147483648+(-1000)=16#80000000+16#FFFFFC18=16#7FFFFC18=2147482648
Example 1
When X0.0 is ON, the instruction adds -100 or 100 to the binary-coded decimal value in X1, and stores the sum in D10.
