So I only can gess: The S7 knows Floating point numbers (REAL in S7) and (nonfloating) Integer numbers (INT in S7) Look here for details: https://www.automation.siemens.com/mdm/default.aspx?DocVersionId=42082458891&Language=en-US&TopicId=36998105611 mfG / Best Regards Dirk

(0)  A floating signal is a signal that has no grounded reference where a non-floating signal either gas the + or the - connected to the ground. A floating signal has the advantage that an eart fault does not cause any interruption but the signal simply becomes non-floating. In order to prevent short circuits, the earth faults are detected by special equipment and alarmed so that the problem can be fixed before a second earth fault occurs. Hope this helps, David
