8-4. Table of Memory Areas

Item
External External input relay
I/O relays
This relay feeds signals to the programmable controllers
from an external device such as a limit switch or
photoelectric sensor.
External output relay
This relay outputs the program execution result of the
programmable controllers and activates an external
device such as a solenoid or motor.
Internal
Internal relay
relays
This relay does not provide an external output and can
be used only within the programmable controllers.
Special internal relay
This relay is a special internal relay which has specific
applications. This relay cannot be used for output. Use it
only as a contact. Refer to page 198, "8-6. Special Internal
Relays".
Timer/ Timer contact
counter
This contact is the output of a
TM
If a instruction has timed out, the contact with the
same number turns ON.
Counter contact
This contact is the output of a
CT
If a instruction has counted up, the contact with
the same number turns ON.
/
Timer counter set value
The timer/counter set value area is a memory area
where the set value of the
instructions is stored. Each timer/counter set value area
consists of 1 word (1 word = 16 bits). The address of this
memory area corresponds to the
number.
/
Timer counter elapsed value
The timer/counter elapsed value area is a memory area
where the elapsed value of the
instruction is stored. Each timer/counter elapsed value
area consists of 1 word (1 word = 16 bits). The address
of this memory area corresponds to the
instruction number.
Notes:
• Timer/counter contacts are represented in decimal.
• Word addresses are represented in decimal.
• The addresses for relay bits (X, Y, and R) are represented by a combination of word addresses (decimal)
and hexadecimals. The least significant digit is hexadecimal and the rest of the digits are decimal.
