Description
• The contents of DM0000 is transferred to the internal register when input relay
0000 is ON.
• The contents of the internal register (DM0000) and the value specified by the
operand ($00FF) are EORed (exclusive OR) for each bit and the result is input
back to the same register.
• When the operation result is "0", special utility relay 2010 turns ON.
• The contents of the internal register is transferred to DM0001.
• The following shows the case when DM0000 is "$F0F0".

Contents of DM0000 are
transferred to the internal
register.
Only when the bits of the
internal register and the
operand have different values,
will the exclusive logical sum
be "1". These values are EORed for each
bit to obtain exclusive OR value.
The result is trans-
ferred to DM0001.
