DDE Client Example

DDE Client Example

Hello
I am use DDE Client Driver in the zenon Supervisor 7.10. As DDE Server used Microsoft Excel (English) files Test.xlsx, SHEET1.
My settings for DDE Client Driver:
Name: DDEVARIABLEINPUT
Server: EXCEL
Topic: [TEST.XLSX]SHEET1
Item: R1C1
Variable properties:
Name: DDEVariableInput
Driver: DDE_CLIENT32 - DDE Client Driver
Driver object type: PLC maker
Data type: INT
Net address: 0
Offset: 0
Excel is running and it is open file: Test.xlsx
The Numeric associated with DDEVariableInput displays empty rectangle.
Please tell me where is my mistake?
Thanks.
P.S. Matlab - Microsoft Excel, with the same configuration is working properly.
Using a variable zenon (with flag "Permanently read variable - DDE active") of Microsoft Excel just happens normally.
