Turns on or off based on external
input.
Externally outputs on or off state
Relay which turns on or off only within
program.
This relay is a shared relay used for
PLC link.
This goes on when the timer reaches
the specified time. It corresponds to
the timer number.
This goes on when the counter
increments. It corresponds to the
counter number.
Relay which turns on or off based on
specific conditions and is used as a
flag.
Code for speciyfying 16 external input
points as one word (16 bits) of data.
Code for specifying 16 external output
points as one word (16 bits) of data.
Code for specifying 16 internal relay
points as one word (16 bits) of data.
Code for specifying 16 link relay
points as one word (16 bits) of data.
Data memory used in program. Data
is handled in 16-bit units (one word).
This is a shared data memory which is
used within the PLC link. Data is
handled in 16-bit units (one word).
Data memory for storing a target
value of a timer and setting value of a
counter. Stores by timer/counter
number
Data memory for storing the elapsed
value during operation of a
timer/counter. Stores by timer/counter
number.
Data memory for storing specific data.
Various settings and error codes are
stored.
Register can be used as an address
of memory area and constants
modifier.
