Operand
Internal register
DM0000
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 7000 to 7015.

DM0000
Sets C001.
Sends the data of 7012 to 7015 to internal
register.
Shifts the value of internal register to right by
12 bits and writes it into DM0000.
Sends the data of 8000 to 8003 to internal
register.
Shifts the data of internal register to left by 4
bits, ORs the internal register data and the
data of DM0000, and sends the ORed data to
internal register.
Converts the data of internal register to BIN
data and writes it into C001.

Application of EORA instruction
■ Judgement of matching data
Turns ON 0500 (“OK” output) when the ON/OFF statuses of input relays 7000 to
7007 match the DM0000 setting value.

Coding
For easy comprehension, the following data is set temporarily.
When 2010 is ON, the two values match.
When 2010 is OFF, the two values do not match.
➮ Refer to p. 3-164.
Application of SRA/SLA instructions
■ Separate input of BCD
Fetches only 2 digits of the BCD digital switch (7012 to 7015 for the 1st digit, 8000 to
8003 for the 2nd digit) and sets it as the counter value.
