3. Operands for Basic Instructions
1) Description of Operands
■
External input relay (X), external output
relay (Y), internal relay (R)
• The lowest digit for these relay’s X, Y, and R numbers
is expressed in hexadecimal and the second and higher
digits are expressed in decimal to enable both bit and
word processing.
Notes:
• Refer to page 65, “3. I/O Allocation in the FP1”, for details about relay numbers.
• Any external output relay (Y) which is not used as an external output can be assigned as an internal relay
(R).

This relay does not provide an external output
and can be used only within the Programmable
Controller.
This relay outputs the program execution result
of the Programmable Controller and activates an
external device such as a solenoid or motor.
This relay feeds signals to the Programmable
Controller from an external device such as a
limit switch or photoelectric sensor.
This relay is a special internal relay which has
specific applications. This relay cannot be used
for output. Use it only as contact. Refer to page
223, “8-3. Table of Special Internal Relays”.
This contact is the output of a timer instruction
(TM). If a timer instruction is timed out, the
contact with same number turns ON.
This contact is the output of a counter instruction
(CT). If a counter instruction is counted up, the
contact with same number turns ON.
