Introduction
Remote I/O communications regularly exchange data between the master and slave.
Communications are carried out at the timing of occurrence of events by message
functions.

About copyrights and trademarks
The DeviceNet I/F option is an interface for controlling the F381A/F388A with PLC.
By using DeviceNet, the F381A/F388A can be controlled directly from the PLC, resulting in substantial
reductions in wiring.
The supported functions include reading of the present indicated value and status, commands such as D/Z,
waveform functions, reading and writing of set values, etc.
(* Since set values and waveforms are read and written by message functions, use a master that supports
them.)
Parameters such as a slave are to be set at the front of the F381A/F388A. Also, there is no need to set the
baud rate of the F381A/F388A since it automatically follows the master.
In this document, outputs refer to signals from the master to the slave (F381A/F388A), and inputs refer to
signals from the slave (F381A/F388A) to the master.

5. About remote I/O
The F381A/F388A can send status and indicated values through DeviceNet with a delay of approx.
100msec compared with external I/O signals of the main body (in simple remote I/O
communications).
Furthermore, the delay time is affected by the cycle time of the communications, scan time of the
PLC, etc.
Therefore, for cases where the speed is severe, use the control connector of the main body, and not
via communications.
In a line manner, since input signals such as the D/Z command also cause a delayed time when used
via communications, use the control connector for cases requiring speed.
Input signals (F381A/F388A → Master) are output to communications and the control connector in
parallel irrespective of settings of the main body.
For output signals. (Master → F381A/F388A), communications or the control connector can be
selected on a block-by-block basis.

Use it for acquiring judgment results by using the hold function. If displacement needs to be
judged, also use DPM. It is not used if the hold function is not used. Hold results are output.
LO： Turns ON when the hold result falls below the LO limit, and the output is held.
HI： Turns ON when the hold result exceeds the HI limit, and the output is held.
OK： Turns ON when judgment is made during measurement and the LO and HI outputs are
not ON after completion of the measurement. OK will not turn ON if no hold is made
for the specified Number of Use Sections.
* Please fetch the inputs in synchronization with the Complete of n+2.
Use Overload to stop the equipment in case of emergency due to the excess load applied to the
sensor. Irrespective of the measurement status, it turns ON at the Overload. It turns OFF, when
the Overload is released.
Use it for recognizing the completion of measurement. It turns ON when the measurement is
completed.
Use it for acquiring judgment results by using the waveform comparison function. It is not used
if the waveform comparison function is not used. Waveform comparison results are output.
LO： Turns ON when the waveform comparison result falls below the LO limit, and the
output is held.
HI： Turns ON when the waveform comparison result exceeds the HI limit, and the output is
held.
OK： Turns ON when the Compare Area is passed through during measurement and the LO
and HI outputs are not ON after completion of the measurement. OK will not turn ON if
the measurement does not reach the Compare Area or the Reference Point of Relative
Comparison when Relative Comparison is made.
* Please fetch the inputs in synchronization with the Complete of n+2.
・Load OK
Use it for recognizing the abnormality of the load sensor. It is normally ON. It turns OFF with a
sensor error (sensor ±error), or display error (±OVER), or when load exceeds the Overload or
when the Load-Digital-Zeroed value exceeds the Digital Zero Limit. It also turns OFF when the
Start, Reset, or Load Digital Zero signal is ON.
・DPM OK
Use it if the X-axis of the waveform represents displacement. It is not used when the X-axis of
the waveform represents time. It turns OFF when measuring points of 10 data or more are
skipped because the pacing of displacement is too fast. It also turns OFF when the Start, Reset,
or DPM Positioning signal is ON.

・Run
Use it for confirming that the CPU is running normally.
When the CPU is running normally, switching between ON and OFF is done about every 0.5
sec. If it is ON or OFF for a few seconds, there may be something wrong.
・SD OK
Normally use it if the SD card slot option is used. It turns OFF with a memory card error*

6-3.About output data
Load Digital Zero
Perform Digital Zero by unloading the load sensor before measurement to simply adjust the
deviation of the zero point of the load by temperature drift, etc. The load is zeroed by turning the
signal from OFF to ON. As long as the signal is ON, the Load OK output is kept OFF.
* Digital zero value is cleared when the power supply is turned on.If you want to
maintain digital zero value, please do zero calibration instead.
DPM Positioning
Use it for adjusting the zero point of displacement just before measurement start.
It is not used if the X-axis of the waveform represents time or the zero point of displacement does
not need to be adjusted. By turning the signal from OFF to ON, displacement is brought to the DPM
Positioning set value, and the internal counter of the pulse input is cleared. As long as the signal is
ON, the DPM OK output is kept OFF.

7.About message communications
Start
Use it for starting measurement. By turning the signal from OFF to ON when the Start signal input
is waited for, a “Wait Off” state is brought about, and the Hold Result, Wave Result, Complete,
Load OK, and DPM OK outputs are turned OFF. By turning the signal from ON to OFF, a “Wait
Lv.” State is brought about, or the measurement is started according to the Measurement Start
Condition.
Stop
Use it for stopping measurement. By turning the signal from OFF to ON during measurement, the
measurement is stopped.
Hold
Use only for using the section control function by External Input. It is not used if the hold function
is not used or Change of Section is made by Setting. By turning the signal from OFF to ON, the
hold section is changed.
Reset
Use it for releasing some errors, etc., in emergencies. Irrespective of the measurement status, by
turning the signal from OFF to ON, the Hold Result, Wave Result, Load OK, and DPM OK outputs
are turned OFF, and a “Wait St.” state is brought about. If the Reset signal is turned from OFF to
ON during measurement, the measurement is forcedly stopped and the measurement data is
annulled. For keeping the data, check the data after completion of the measurement, and then turn
the Reset signal from OFF to ON.
Prohibit Touch Panel
Use it for controlling so as to prevent touch panel operations. As long as the signal is ON, no operation
can be performed with the touch panel.
Backlight On
Use it for controlling the backlight externally. By turning the signal from OFF to ON, the backlight
lights up. As long as the signal is ON, the backlight stays ON.
Work
Use it for using two or more work Nos. It is not used if only work No. 0 is used. Specify work
No(s). to be used before measurement.
7. About message communications
By using message communications, the following can be read and written.
Be aware that the setting range varies depending on the settings of the main unit.
* For message communications, a master that can carry out message communications and CPU unit
need to be combined.
・Set value： Read / Write / Read (all) / Write (all)
・Measurement range： Read
・Waveform： Read / Write
・Hold result： Read
・Wave No.： Read / Write

■Reading waveform
A waveform is an array of up to 2048 (data No. 0 - 2047) load data. The data of the waveform can
be read by specifying the data No. range to read.
However, the amount of load data that can be handled in one message communication is up to 32.
The waveform is divided into 64 (32×64 = 2048), and the waveform is read 64 times.
* The range to read can be specified as narrowed by reading the measurement range.
(Depending on usage, all of 2048 may not be used for measurement.)
* The time required to read one waveform (load) (2048 data) is approximately 4 seconds.

■Writing waveform
A comparison waveform upper limit (lower limit) is an array of 2048 (data No: 0 - 2047) load data.
The comparison waveform is written by specifying data Nos. and load, and one piece of load data is
rewritten in one message communication. Therefore, for rewriting all of one waveform, writing
operation is to be performed 2048 times.
Example) Rewriting the comparison waveform upper limit (work 0)
① Writing to data No. 0 of the comparison waveform upper limit (work 0)
