Dear Roby, the variable 'init' is placed in the TEMP-section, so it is stored in the local-data-stack. After your FB is finished, this memory-cell will be released and used by the following blocks. So the content of the variable may be overwritten. To initialise a variable in the TEMP-area, you have to write some code - it does NOT have an initial-value. Please have also a look at the excelent posting of fritz in this thread. Best regards, yy1 |
