ramaslabas Posted July 30, 2007 Report Posted July 30, 2007 There are different memory areas and you can use all of them. Even SM. They can be retentative V and M areas. In user manual is everything... Quote
Crossbow Posted July 31, 2007 Report Posted July 31, 2007 V is typically used as bytes or words for numeric storage with M typically used bit by bit for single bit signals. It's detailed out quite well in the S7-200 Programming Manual, which is in the Downloads section here. Quote
