Example 5.5
Inversion
Script
if (([D0000.01] & ~[D0001.01]) | [D0002.01])
{
SET([D0003.01]);
}
else
{
RST([D0003.01]);
}
Operation Description
If the bitwise logical OR operation on the value of D0002.01 and the result of the bitwise logical AND operation on the value of
D0000.01 and the inverted result of the value of D0001.01 is 1, then D0003.01 is changed to 1.
If the bitwise logical OR operation on the value of D0002.01 and the result of the bitwise logical AND operation on the value of
D0000.01 and the inverted result of the value of D0001.01 is 0, D0003.01 is changed to 0.
The operation is the same as the following ladder diagram.
D0000.01 D0001.01
D0002.01
Example 5.6 Left shift
Script
[D0300] = [D0100] << [D0200];
Operation Description
The value of D0100 is shifted to the left by the value of D0200 and the result is stored in D0300.
For example, if the value of D0100 is 1 and the value of D0200 is 3, 1 is shifted 3 bits to the left, and the result of 8 is stored in
D0300.
Example 5.7 Right shift
Script
[D0300] = [D0100] >> [D0200];
Operation Description
The value of D0100 is shifted to the right by the value of D0200 and the result is stored in D0300.
For example, if the value of D0100 is 8 and the value of D0200 is 3, 8 is shifted 3 bits to the right, and the result of 1 is stored in
D0300.
