Generating Virtual External Inputs Section 8-3
165
If a file output by the Data Replay Tool exists, specifying the I/O memory as
an output file can be omitted by specifying the file as an output template when
starting the Data Replay Tool. Specifying a template file by the Data Replay
Tool will copy the I/O memory specification (parameter line) of the template
file to the output file as is.
8-3-4 Multipoint Data Collection Tool
Time-series I/O memory data (Data Replay File) acquired from an actual PLC
can be replayed on the Ladder Engine using the Data Replay Tool. Unlike
Data Trace, data can not be acquired every cycle. However, time-series data
of more than 50 words can be acquired. This function enables to take in data
from an actually running PLC and to replay the data along with the program
using the CX-Simulator, allowing confirming the operations.
Note Refer to 8-4 Running by Virtual External Inputs for replay with Data Replay
Tool.
Note The CX-Server is required to use the Multipoint Data Collection Tool.
Therefore, be sure to install the CX-Programmer Ver.1.20 or after on the
same computer.
Note The Multipoint Data Collection Tool fails to acquire data of operations shorter
than a few tens of milliseconds. Also, replaying actually acquired data on the
PLC may cause time lags because the tool does not acquire data in synchro-
nization with the PLC’s cycle time.
Setting for Multipoint Data Collection
In order to acquire and save multipoint data from an actual PLC, after clicking
the [Start] button on the task bar, select [Program] | [Omron] | [CX-Simulator] |
[Multipoint Data Collection Tool].
