Functions
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.
This goes on when the timer increments.
Relay which turns on or off based on
specific conditions and is used as a flag.
This relay only turns on during one scan at
the start of the execution condition.
This relay ensures that error conditions
that are freely allocated by the user are
memorized in the memory.
This relay is for input/output processing
during operation, without depending on
usual I/O refresh.
Code for specifying 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).
This device is for accessing the unit
memory of intelligent units. Its size varies
by unit, and is allocated by default.
Data memory for storing specific data.
Various settings and error codes are
stored.
