IMPORTANT
• While DDE is running, do not change the project
name (topic name).
• To save files using Excel as a DDE client, set Files
of type to Excel 97-2003 book (*.xls).
Note
• If data collected by the DDE server is in error, it is
output using indications other than values.
For the different types of error data, see section
4.9.2 .
• The time information that is used for DDE queries is
the PC time in which the server is installed. The time
when the collected data is set to the DDE server is the
time that is output.
Therefore, if Data time is set to Device time, the time
and value of the data on the Monitor Page or data
recorded to the data file will not be synchronized to
the time and value output by the DDE server.
• The data number is output only when Data time is
set to PC time. It is not output when Data time set to
Device time.
• If communication between the data collection device
and the server is disconnected and Data time is
set to PC time, OFF is output for the data value. If
set to Device time, data updating stops regardless
of whether FIFO is being used. This is the same
behavior as when the data collection from the device
is delayed.
