Item
This parameter specifies the maximum value for the number of steps to which a sequence program
can be input.
Memory 1) The upper limit is determined by the capacity of the built-in memory or attached optional
Capacity memory.
2) The memory capacity includes the program memory, file registers, comment area and other
special setting capacity.
This parameter incorporates comments into the program memory.
1) Because comments remain in the PLC, the contents can be easily understood at the time of
Comments
maintenance.
Capacity
2) Up to 50 comments can be input when one block is specified, and one block requires 500 steps
in the memory capacity.
This parameter incorporates data registers into the program memory.
1) A sequence program and control data such as machining set values can be handled together,
File Register
which is convenient.
Capacity
2) Up to 500 file registers can be created when one block is specified, and one block requires 500
steps in the memory capacity.
1) This parameter sets whether or not the special block/unit initial value setting function is used
When this function is used, this function requires 4000 steps (8 blocks) in the memory capacity.
Special
2) This parameter sets whether or not the positioning setting (constants and setting table) in the
Function
TBL instruction is used.
Memory
When this setting is used, this setting requires 9000 steps (18 blocks).
Capacity
3) This parameter sets whether or not the built-in CC-Link/LT function is used
When this function is used, this function requires 500 steps (1 block) in the memory capacity.
Latch range This parameter enables to change the latched (backed-up) device range and non-latched (non-
setting backed-up) device range inside the PLC.
Special This parameter sets the initial values of the buffer memory (BFM) for each special block/unit
Function Block number.
Settings It is necessary to set the memory capacity.
Built-in CC-Link/ This parameter sets the transmission speed, point mode and station information.
LT Setting It is necessary to set the memory capacity when setting the station information.
This parameter sets the PLC operation mode without a battery.
Battery Less
When the batteryless mode is selected, the PLC automatically stops detection of low battery voltage
Mode
error, and initializes the contents of latched (backed-up) devices.
This parameter sets the PLC operation mode with a battery.
When the battery mode is selected, general-purpose devices can be changed to the latched
Battery mode
(backed-up) type.
MODEM This parameter automatically sends a specified AT command as the initialization command to a
Initialized modem connected to the serial port.
This parameter specifies the input number of the RUN input described above in the range from X000
to X017.
RUN Terminal

(X000 to X007 in the FX
(X000 to X015 in 24-point type FX
This parameter corresponds to the following settings by specifying each contents on the personal
Serial port computer screen:
operation Setting of the communication format (D8120, D8400 and D8420)
setting Setting of the station number (D8121 and D8421)
Setting of the timeout check (D8129, D8409 and D8429)
This parameter sets interrupt inputs for the maximum speed, bias speed, creep speed, zero return
Constant setting speed, acceleration time, deceleration time and DVIT instruction.
It is necessary to set the memory capacity.
Individual dual
This parameter sets the operation table. It is necessary to set the memory capacity.
