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.
