Arithmetic flag
2009 No change
2010 Turns ON when the internal register is "0" after an EORA operation. Turns
OFF at other times.
2011 No change
2012 The DM or relay indirectly addressed with #TM is out of range.

Tips
Turning output 0500 ON when inputs 0000 through 0015 have the same value as a
constant ($0F0F)
When the values match, special internal relay 2010 turns ON and output relay 0500
turns ON.
In this example, the constant is "$0F0F", or "0000 1111 0000 1111". Therefore,
output relay 0500 turns ON when input relays 0000 through 0003 and 0008 through
0011 are ON.
Application of EORA instruction
■ Judgment of matching data
Turns ON 0500 when the ON/OFF statuses of input relays 0100 to 0107 match the
DM0000 setting value.
Coding
When 2010 is ON, the two values match.
When 2010 is OFF, the two values do not match.

Operand
Internal register
Internal register 2010 is OFF. When the
value of internal register is 0000, 2010 turns ON.
Judges match between the operand and the
data of 0100 to 0107.
