good greeting I hope you are in good health I have a problem creating an FB when I choose state from the table, define the variable, choose the data type, struct, and give the storage command, the log appears (A STRUCT without components is illegal) What letter is similar to U in English? Thank you very much for helping me ------------------------------------------------------------------------------------------ |

hello anial; This thread was originally for S7-300 CPUs, is it still the case for your problem? The error message states that you have not created internal variables inside yout STRUCT variable declaration. The examples attached below show how a STRUCT variable is expecting sub-variables to define the working structure of the variable. The first example uses STL, but the principle applies in whatever programming language you are using. The screenshots were taken for the Programming with Step 7 v5.5 manual. https://support.industry.siemens.com/cs/ww/en/view/45531107 Hope this helps, Daniel Chartier |
