[leonlai 0]

Hi everyone, I have a dumb question here: 1) I have 2 CPU S7-1200 & 1 TP1200 & Switch: (connect via EN/IE) I'm going to program these 2 CPUs, For example if 1st CPU return an A results, is that possible 2nd CPU use A resuls as its own condition ??? So if YES, just leave results A as an GLOBAL DATA of 1st CPU then 2nd CPU can access it anytime in anycondition ??? or I have to do something ?? 2) Anybody know where I can set the Autosave time for auto backup ??? I've lost my work when I cannot save my work on Network drive and TIA just close the programm without saving anyof my work ! And I found a backup in my file but it was yesterday >_< Thanks

Look at the "GET" and "PUT" blocks under the S7 Communications tabs in the Instruction View. GET = Gets information from a remote CPU PUT = Write Data to a remote CPU
