5.5 Bitwise Operators
Script
Operation description
If the bitwise logical AND operation on the values of LM100 and LM101 is 1, LM200 changes to 1.
If the bitwise logical AND operation on the values of LM100 and LM101 is 0, LM200 changes to 0.
The operation is the same as the following ladder diagram.
Script
Operation description
If the bitwise logical OR operation on the values of LM100 and LM101 is 1, LM200 changes to 1.
If the bitwise logical OR operation on the values of LM100 and LM101 is 0, LM200 changes to 0.
The operation is the same as the following ladder diagram.
Script
Operation description
The logical XOR operation on the value of LDR100 and each bit in 0xFF is stored in LDR200.
For example, if the value of LDR100 is 15 (0x0F), then LDR200 is 240 (0xF0).
■ Example 5.5.1 Logical AND
if ([LM 100] & [LM 101])
{
SET([LM 200)]);
}
else
{
RST([LM 200]);
}
LM100 LM101 LM200
■ Example 5.5.2 Logical OR
if ([LM 100] | [LM 101])
{
SET([LM 200]);
}
else
{
RST([LM 200]);
}
LM100
LM101
LM200
■ Example 5.5.3 Logical XOR (exclusive OR)
[LDR 200] = [LDR 100] ^ 0xFF;
