Summary:
Question: Does the ReRead() function have any effect on global cicode variables? 

Solution:
The function ReRead() has no effect on global cicode variables. This function will force any PLC variables to be re-read from the PLCs.

Common causes of problems with ReRead() are using the TaskNew() function to start a function. When this function is used the function can be called without first requesting data from the PLC. In this case a ReRead() would read the PLC variables.
