Overview of Functions

Remote Control Function (/R1 Option)
When a contact or open collector signal is applied to the remote control terminal, a
predetermined operation is carried out.
Arbitrary controls can be assigned to the eight remote control terminals. The available
controls are listed below.
For the setting procedure, see section 10.7.
Function Remote Signal Operation
None - No operation.
Start/Stop Edge Start/stop acquiring data to the internal memory.
⇒
“Sections 8.4 and 8.5”
Trigger Trigger Trigger to start acquiring event data to the internal
memory (valid only when event data are specified to
be acquired to the internal memory and the trigger
used to start the acquisition is set to key trigger
⇒
“Section 8.11”)
Alarm ACK Trigger Release alarm display/relay output (valid only when
the operation of the alarm display or output relay is
set to “hold”
⇒
“Section 6.4”).
Time adj Trigger Adjust the internal clock to the nearest hour.
Computation Edge Start/stop computation (only for models with the
computation option (/M1).
Computation reset Trigger Reset the computed value of the computation
channel (reset to 0, only on models with the
computation option (/M1) while the computation is
stopped).
Manual sample Trigger Write the instantaneous values of all channels to the
internal memory once.
Load setup data 1 to 3 Trigger Load and activate the setup data file that had been
created and stored in the external storage medium.
Messages 1 to 8 Trigger Display messages 1 to 8 on the trend display and
write them to the internal memory.
Remote signal (edge and trigger)
The above operations are carried out on the rising or falling edge of the remote signal
(edge) or the ON signal lasting at least 250 ms (trigger).
Rising/Falling Trigger
Rising Falling
250 ms or more
For contact inputs, the remote signal rises when the contact switches from open to close
and falls when the contact switches from close to open. For open collector signals, the
remote signal rises when the collector signal (voltage level of the remote terminal) goes
from high to low and falls when the collector signal goes low to high.
