Hi saeedplc, Interface area stores various signals over which panel communicates with PLC, like life bit, job mail box, date and time, ... It was needed to communicate with S5 PLC, but if you dont need specific info contained in it, S7 doesnt need it, although it might cause message on panel indicating that configured DB is not found in PLC. If you want more details about interface area check out communication manual. You can find it here http://support.automation.siemens.com/WW/view/en/1137086 Kind regards, BV |
