2. Select [File] | [Set Communications] to set [Device Type] to be connected
and [Network Type]. Always select the CS/CJ Series for [Device Type].
3. Click the [New] button to display the [Set Address] dialog box. Input ar-
bitrary word data in the form of [Start Address]-[End Address], followed
by the OK button. Multiple data can be registered. Further, the maxi-
mum number of addresses that can be registered with the currently set
communications method and the present registered number are dis-
played on the status bar. Also, the saved address can be read by [File] |
[Open Address List].
Note The number of sampling is limited as follows depending on the communica-
tions method because this tool acquires data from an actual PLC using FINS
commands.
Via Peripheral bus
·
Via SYSMAC WAY
·
Even for other networks, the number of sampling is limited depending on
·
the frame size of the FINS command at that time.
4. Input [Sampling interval]. A value of 10 or more (to be multiplied by
10 ms) can be set with the default value of 20 (200 ms).
Note The [Sampling Interval] set here is, from the internal viewpoint, the one in
which the Multipoint Data Collection Tool issues a FINS command in order to
read the registered addresses from an actual PLC. The actual intervals at
which a response is returned from the PLC may differ from the specified
interval depending on the cycle process timing on the actual PLC.
5. Check [Acquire data as every-cycle data] as required. In this case, the
data acquired is saved in a file as every-cycle data, independently of the
specified sampling interval and the PLC's cycle time. When not timing
but confirming operation with ON/OFF of the bits is important, the saved
file with a check mark can be replayed fast on the CX-Simulator.
Note If this option is not checked, the data will be saved to the file with the esti-
mated cycle count calculated from the actual PLC's average cycle time when
starting sampling and the sampling interval set in the Multipoint Data Collec-
tion Tool. When this data is replayed on the CX-Simulator, the data replay
speed may become very slow if the cycle count of the CX-Simulator pro-
ceeds slowly.
6. Input to [Sampling data file] a name of file where sampled data will be
saved. Also, clicking the [Browse] button allows to specify a destination
file name directly.
Note If an existing file is specified, the file will automatically be overwritten when
sampling starts. Make sure in advance the file may be overwritten.
7. Clicking the [Start] button will start sampling data according to the set
contents.
8. Once the sampling is started, the elapse time after starting sampling is
displayed in [Time:].
