F i r s t - R u n
Description
It calculates the value of logical variable, that assumes value 1 at the first run of the control. At the
second run it becomes equal to and remains at this value.
This compound block is obsolete and its function is now perfomed within Win+Drive. In the previous version,
the user had to ensure that this compound block was performed
any other compound in his scheme. To
accomplish this, he should have used a control connection line.
