The 90/180 rule applies to any combination of short-stay visa. (There are special cases which give more days, but that's not the problem here.) Simply count the days of presence in Schengen and if you are below 90 days within the last 180 days you are fine as far as 90/180 is concerned.
The previous visit might make it easier to get the new visa, or to get a multiple-entry visa, since you have a travel history now.
