System version
The system version of the measuring, control, and automation system is determined by the
compatibility index of the base unit.
Example composition of a version number for the central processing unit: 248.xx.yy
248 = basic version, xx = compatibility index (system version), yy = current version
In this document, functions which depend on the system version are marked accordingly (e.g.
"as of system version 02").
