Operands:

: Data source value 1 S
2
: Data source value 2
Description:
1. Compare the contents of S
1
and of S
2
. For example, “AND&” compares S
1
and of S
2
, and if the
comparison result is NOT 0, the instruction is true, and if it is 0, the instruction is false.
2. The AND# instruction is an input instruction.

3. Operators:
& : Logical “AND” operation, | : Logical “OR” operation, ^ : Logical “XOR” operation
4. If a 32-bit counter is used with this instruction, be sure to use the 32-bit instruction (DAND#). If
the 16-bit instruction (AND#) is used for a 32-bit counter, a “Program Error”, will occur and the
red “ERROR” indicator on the ELC panel will blink.
Program Example:
1. When X0=ON, using the AND& (Logical “AND” operation) instruction to compare the contents
of C0 and C10. If the result is not equal to 0, Y20=ON.
2. When X1=OFF, using the AND| (Logical “OR” operation) instruction to compare the contents
of D10 and D0. If the result is not equal to 0, set Y21=ON.
