Grazzer Posts: 76 Rating: (1)	Hi everyone! I have one simple question: what are the differences between restarts of PLC from SIMATIC Manager: 1. From CFC Editor [URL=http://img180.imageshack.us/i/49915302.jpg/][IMG]http://img180.imageshack.us/img180/9448/49915302.jpg[/IMG][/URL] 2. From Simatic Manager Explorer (hot key ctrl+L) [URL=http://img707.imageshack.us/i/59375204.jpg/][IMG]http://img707.imageshack.us/img707/9459/59375204.jpg[/IMG][/URL] 3. Via PLC-Compile and Download objects [URL=http://img510.imageshack.us/i/47968117.jpg/][IMG]http://img510.imageshack.us/img510/1213/47968117.jpg[/IMG][/URL] Is it best way to use the first method for saving values in PLC? Thanks a lot

IfI am right so there is always a pop-up window that asks if you would like cold or warm restart. You can find difference in the attached file Attachment Startup Modes.pdf (279 Downloads)
	Best Regards

You can then download using the CFC download option. You should never use the station download option as it doesn't compile the project and hence doesn't check for timestamp error and block consistency. For entire project download or any changes in harware/connection your third option is good. Cheers Poker
