Reading Values from the I/O Server into Excel
Values may be read directly into Excel spreadsheets from the server by entering a DDE
formula into a cell using the following format:
=applicationname|topicname!itemname
Example formula:
=S3964R|S115U!DB10DW20KF
where:
S3964R
Is the name of the server
application name.
S115U
Is the exact topic name defined in the server for the
PLC.
DB10DW20KF
Is the actual location in the PLC that contains the data
value. This is the item name.
In this example, each time the value of
DB10DW20KF
changes in the
PLC,
the server
will automatically send the new value to the cell containing the formula in Excel.
Note
Refer to the Microsoft Excel manual for complete details on entering Remote
Reference formulas for cells.
