System description
Explanation of summary output 0-sheet, 1-sheet and 2-sheet:
If the unit is used in simultaneous mode (more than 1 sensor in a program e.g. 1+3+4), the
measurement result is formed as summary output (via I/O and via the Fieldbus Byte 8-11). The
priorities are:
2-sheet is issued if at least one sensor detects 2-sheet.
1-sheet is issued if all sensors detect 1-sheet.
0-sheet is issued if no 2-sheet is detected but at least one sensor detects 0-sheet.
