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

Data memory used ind 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.
