Morning
Im going to work on this project this afternoon, but just a quick question regarding the DB interface while it has been brought up. This is hypothecial btw but;
1- say that I was to modify and exsiting FB within a program that is already in operation. I take it you should tread with caution as the IDB may contain information that is required within the program, or will it be just regenared again whent the FB is regenerated and called??
2- When you download a project onto a PLC and it asks you to download system data, is that system data to information within the DB's, or is that something else??
