9. Clicking the [Stop] button will stop the data sampling to save the sampled
data in the file.
Note When the sampling count from the sampling start exceeds 65,535, the file is
automatically divided. In this case, the name of second sampling data save
file is the specified file name with "2" appended at the end of it. (e.g. "sam-
ple2.csv" for "sample") Further, when the sampling count for the second save
file exceeds 65,535, "3" is appended similarly. (e.g. "sample3.csv" for "sam-
ple")
10. The registered address can be saved by [File] | [Save Address List] to be
reused after the Multipoint Data Collection Tool is started next time.
Note In order to keep time accuracy to some extent in replaying with the Data
Replay Tool, follow the next steps.
Step 1: Check [Acquire data as every-cycle data] to sample at the sampling
intervals of N (ms).
Step 2: When replaying the data, set the above sampling interval of N (ms) to
Minimum Cycle Time, and then run the CX-Simulator with the mini-
mum cycle time.
Note Be sure to set a sampling interval greater than the PLC's cycle time. In addi-
tion, when setting a sampling interval shorter than 200 ms, or registering
addresses of more than 100 words, be sure to connect with the Peripheral bus
and to set a fastest possible baud rate. Further, exit all other applications.
Otherwise, data may not be acquired normally. In this case, the Multipoint
Data Collection Tool displays an error message to stop sampling.

"Received an error response."
"Timing Error. Check the log
file (Errorlog.txt) after exiting."
"Data sampling stopped."
I/O Condition Expressions describe the operation that sets values to the I/O
memory area (output expression) after the specified time (delay time) when
the conditions of the specified I/O memory (conditional expression) hold. The
combination of the conditions generates virtual external outputs.
An error occurred in the received data. Non-existent
EM bank may have been tried to read or communica-
tions condition may be unstable.
Data can not be acquired at the specified sampling
intervals. To avoid this situation, either extend the
sampling interval or reduce the sampling address
count.
If the CX-Programmer is activated at the same time
and connected online, once place it offline.
Alternatively, setting the maximum value (25.5 ms) to
[Fixed Peripheral Servicing Time] in the PLC Setup
may be effective. (although the cycle time extends)
For details, check the Errorlog.txt that is created in the
same folder as for the saved CSV file.
The above situation repeated 10 times continuously or
communications with the PLC is broken. Check the
communications path with the PLC.
