Summary:
If I call a cicode function from Excel all the PLC data is set to 0. What is causing this problem.? 

Solution:
CIT has confirmed this to be a problem in Citect for Windows versions to 4.20. This problem has been fixed in version 5.00. You may also work around this problem by calling the ReRead(1) function as this first line of the function you want to call from DDE.
