Hello JL; Sorry, I do not remember seeing such an error code in my S7-300 projects. And code 30:558 is not described in the Error Codes document I generally relied on: What is the meaning of the error codes (xxxx:yyyy) in STEP 7? https://support.industry.siemens.com/cs/ww/en/view/770453 Does the Help button give any useful indication? If not, I would suggest a Support Request, to ask a Siemens tech directly; the link is at the top of this page. As far as your DB is concerned, it simply means that inside your FC block you are opening a specific DB and read or write from it. Hope this helps, Daniel Chartier |
