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

Contents of DM0000 are
transferred to the internal
register.
Only when both bits of the
internal register and the
operand are "0", will the logical
sum be "0". These values are ORed for
each bit to obtain logical sum.
The result is transferred
to DM0001.
