Hello, with SFC 22 (CREAT_DB) you create a DB during runtime in the CPU, but its contents are not preset. (The values in the said DB can be completely random.) For this reason it is necessary to preset the contents of the DB created during runtime. Using SFC 21 (FILL) you can define the contents of the DB previously created during runtime. The appendix shows an example in ASCII mode. Example: FUNCTION FC 1 : INT
VAR_OUTPUT VAR_TEMP BEGIN I'm sorry, but this example is in AWL. In SCL you have to use the AT-function for making a pointer. See in this case the informations of the FAQ: http://support.automation.siemens.com/WW/view/de/21946854 |
