Bit Name Signal status, description
Valid for find reference marker and measurement on-the-fly.
Bit Meaning
0 Function 1 Reference marker 1
Probe 1 rising edge
1 Function 2 Reference marker 2
Probe 1 falling edge
2 Function 3 Reference marker 3
Probe 2 rising edge

Note:
• Bit x = 1 function active
Bit x = 0 function inactive
Valid for find reference marker and measurement on-the-fly.
Bit Meaning
4 Value 1 Reference marker 1
Probe 1 rising edge
5 Value 2 Probe 1 falling edge
6 Value 3 Probe 2 rising edge
7 Value 4 Probe 2 falling edge

Status:
Value 1 - 4
available
Note:
• Bit x = 1 value available
Bit x = 0 value not available
• Only one value can be fetched at a time.
Reason: There is only one common status word Gn_XIST2 to read the values.
• The probe must be configured to a "high-speed input" DI/DO on the Control
Unit.
