1C33:0 SM input parameter Synchronization parameters for the inputs UINT8 RO 0x20 (32

1C33:01 Sync mode Current synchronization mode:
• 0: Free Run
• 1: Synchron with SM 3 Event (no outputs
available)
• 2: DC - Synchron with SYNC0 Event
• 3: DC - Synchron with SYNC1 Event
• 34: Synchron with SM 2 Event (outputs available)
UINT16 RW 0x0001 (1

1C33:02 Cycle time Cycle time (in ns):
• Free Run: Cycle time of the local timer
• Synchron with SM 2 Event: Master cycle time
• DC mode: SYNC0/SYNC1 Cycle Time
UINT32 RW 0x00030D40
(200000

)
1C33:03 Shift time Time between SYNC0 event and reading of the inputs (in
ns, DC mode only) UINT32 RW 0x0002E630
(19000

1C33:04 Sync modes supported Supported synchronization modes:
• Bit 0: free run is supported
• Bit 1: Synchron with SM 2 Event is supported
(outputs available)
• Bit 1: Synchron with SM 3 Event is supported (no
outputs available)
• Bit 2-3 = 01: DC mode is supported
• Bit 4-5 = 01: Input Shift through local event
(outputs available)
• Bit 4-5 = 10: Input Shift with SYNC1 Event (no
outputs available)
• Bit 14 = 1: dynamic times (measurement through
writing of 0x1C33:08)

1C33:05 Minimum cycle time Minimum cycle time (in ns) UINT32 RO 0x00030D40
(200000

1C33:06 Calc and copy time Time between reading of the inputs and availability of the
inputs for the master (in ns, DC mode only) UINT32 RO 0x00002710
(10000
dec
)
1C33:07 Minimum delay time Minimum time between Sync-1 Event and reading of the
inputs (in ns, DC mode only) UINT32 RO 0x00000000 (0

)
1C33:08 Command • 0: Measurement of the local cycle time is stopped
• 1: Measurement of the local cycle time is started
The entries 0x1C33:03, 0x1C33:06, 0x1C33:09 are up-
dated with the maximum measured values.
For a subsequent measurement the measured values
are reset

1C33:0C Cycle exceeded counter Number of occasions the cycle time was exceeded in
OPERATIONAL (cycle was not completed in time or the
next cycle began too early)

1C33:0D Shift too short counter Number of occasions that the interval between SYNC0
and SYNC1 event was too short (DC mode only) UINT16 RO 0x0000 (0

1C33:20 Sync error The synchronization was not correct in the last cycle
(outputs were output too late; DC mode only) BOOLEAN RO 0x00 (0
