Configuring the DAQLOGGER
15. If necessary, set the “Action on Undesired Disconnection.”
After you select the check box, enter the time interval (in seconds) for checking the
recovery of the disconnected recorder.
This auto-reconnecting function checks, at the specified number of seconds, whether
a recorder that experienced a communication error during the initial communication
or a recorder that went out of communication due to some sort of trouble has
recovered or not. If the recorder has recovered, it is rescanned.
Note
• When becoming a communication fault, the data of the recorder is displayed to OFF.
• The following occur in the Monitor and Viewer screens during communication retries.
Monitor screen
If the communication retry is successful, the channel settings of the connected instrument
with which communication was recovered are reloaded, and waveforms are redisplayed. If a
connection with the instrument still cannot be made after a communication retry, the decimal
place, scale, and trip point settings are initialized. If any subsequent communication retry is
successful and the connection is reopened, the correct decimal place is loaded and all monitor
screens are redisplayed. The loading of the channel settings upon a successful retry after the first
communication error is the same as that if no error had occurred during the first communication.
Viewer screen
If the file being logged is to be displayed (if the current data button is pressed) after the
communication retry succeeds, the file is reloaded. If a connection with the instrument cannot
be made during communication, values such as the decimal place and span are initialized.
Therefore if the communication retry is successful, the correct decimal place must be reloaded.
16. If necessary, set “Math.” From the “Action” list box, select the recorder computation
operation to be executed at the start of the scanning operation. This setting is
common to all recorders that have the computation function.
None: Does nothing.
Start: Starts the computation.
Stop: Stops the computation.
Clear: Clears the computed data.
Clear&Start: Clears the computation and then starts the computation.
However, the following restrictions exist depending on the recorder.
• µR recorders do not accept “Clear” action.
• As for VR, DX, MV, and CX “Clear” action operates when the computation is
stopped.
• When the DX/MV/CX is connected to the Ethernet network, administrator-level
login name must be specified (see section 2.6).
17. Click the “OK” button.
