Meaning
Synchronization parameters for the outputs
Current synchronization mode:
• 0: Free Run
• 1: Synchron with SM 2 Event
• 2: DC-Mode - Synchron with SYNC0 Event
• 3: DC-Mode - Synchron with SYNC1 Event
Cycle time (in ns):
• Free Run: cycle time of the local timer
• Synchron with SM 2 Event: cycle time of the
master
• DC-Mode: SYNC0/SYNC1 Cycle Time
Time between SYNC0 event and output of the
outputs (in ns, DC mode only)
Supported synchronization modes:
• Bit 0 = 1: Free Run is supported
• Bit 1 = 1: Synchron with SM 2 Event is
supported
• Bit 2-3 = 01: DC-Mode is supported
• Bit 4-5 = 10: Output Shift with SYNC1 Event
(only DC mode)
• Bit 14 = 1: dynamic times (measurement
through writing of 1C32:08)
Minimum cycle time (in ns)
Minimum time between SYNC0 and SYNC1 event (in
ns, DC mode only)
• 0: Measurement of the local cycle time is
stopped
• 1: Measurement of the local cycle time is started
Entries 1C32:03, 1C32:05, 1C32:06, 1C32:09,
1C33:03, 1C33:06, 1C33:09 are updated with the
maximum measured values.
For a subsequent measurement the measured
values are reset
Time between SYNC1 event and output of the
outputs (in ns, DC mode only)
Number of missed SM events in OPERATIONAL (DC
mode only)
Number of occasions the cycle time was exceeded in
OPERATIONAL (cycle was not completed in time or
the next cycle began too early)
Number of occasions that the interval between
SYNC0 and SYNC1 event was too short (DC mode
only)
The synchronization was not correct in the last cycle
(outputs were output too late; DC mode only)
