• PVSwitching1 to 4 ← Selectable only during loop control with PV switching
Select to register a contact input for switching the input for each internal loop during
loop control with PV switching. This is not selectable for internal loops 5 and 6.
The rising edge signifies “PV2”; the falling edge signifies “PV1.”
Note
[PVSwitching1] or [PVSwitching2] does not appear as a selection, if the [Control mode] box
under [Control] > [#1 Control action, Input setting] is not set to [PVSwitching].
• MemoryStart/Stop
Starts/stops the acquisition of the display data/event data to the internal memory
and the report function (computation option function). The rising edge of the signal
indicates start; the falling edge indicates stop.
If data acquisition is started, applying a rising signal produces no effect. Likewise,
if data acquisition is stopped, applying a falling signal produces no effect.
• Trigger
Acts as an external trigger used to start the acquisition of event data to the internal
memory when in trigger mode or rotate mode. Input a signal for at least 250 ms.
• AlarmACK
Clears the alarm indication and relay output. This is the same function as when the
[AlarmACK] soft key is pressed. Input a signal for at least 250 ms.
• TimeAdjust
Adjusts the internal clock of the CX2000 to the nearest hour depending on the time
when the remote signal is applied. Input a signal for at least 250 ms.
Time the signal is input
Time modification
00 min 00 s to 01 min to 59 s Truncates the minutes and seconds.
Example: 10 hours 01 min 50 s becomes 10 hours 00 min 00 s.
02 min 00 s to 57 min to 59 s The time is not changed.
58 min 00 s to 59 min to 59 s Rounds up the minutes and seconds.
Example: 10 hours 59 min 50 s becomes 11 hours 00 min 00 s.
• MathStart/Stop
Starts/stops the computation. The rising edge of the signal indicates start; the
falling edge indicates stop. This is valid only on models with the computation
function option (/M1).
• MathReset
Resets the data on all computation channels. Input a signal for at least 250 ms.
This is valid only on models with the computation function option (/M1) and while
the computation is stopped.
• ManualSample
Write the instantaneous values of all channels to the internal memory once. Input
a signal for at least 250 ms. This excludes measurement channels set to skip and
computation channels set to Off.
• Panel1Load to Panel3Load
Loads the setup data file named [LOAD1.PCL], [LOAD2.PCL], or [LOAD3.PCL]
stored on the external storage medium and activates the settings. Input a signal
for at least 250 ms. Setup data files named [LOAD1.PCL], [LOAD2.PCL], or
[LOAD3.PCL] must be created and saved to the external storage medium
beforehand.
• Message1 to 8
Displays a message at the position corresponding to the time when the signal was
applied on the trend display. The displayed message is also written to the internal
memory. Input a signal for at least 250 ms.
