6.4.18 Distributed Clocks SYNC Out Unit
6.4.18.1 SYNC Out Activation (0x0981)
Bit Description ECAT PDI Reset Value
0 Sync Out Unit activation:
0: Deactivated
1: Activated
r/(w) r/(w) 0
1 SYNC0 generation:
0: Deactivated
1: SYNC0 pulse is generated
r/(w) r/(w) 0
2 SYNC1 generation:
0: Deactivated
1: SYNC1 pulse is generated
r/(w) r/(w) 0
3 Auto-activation by writing Start Time Cyclic Op-
eration (0x0990:0x0997):
0: Disabled
1: Auto-activation enabled. 0x0981.0 is set au-
tomatically after Start Time is written.
r/(w) r/(w) 0
4 Extension of Start Time Cyclic Operation
(0x0990:0x0993):
0: No extension
1: Extend 32 bit written Start Time to 64 bit
r/(w) r/(w) 0
5 Start Time plausibility check:
0: Disabled. SyncSignal generation if Start Time
is reached.
1: Immediate SyncSignal generation if Start
Time is outside near future (see 0x0981.6)
r/(w) r/(w) 0
6 Near future configuration (approx.):
0: 1/2 DC width future (2
31
ns or 2
63
ns)
1: 2.1 sec. future (2
31
ns)
r/(w) r/(w) 0
7 SyncSignal debug pulse (Vasily bit):
0: Deactivated
1: Immediately generate one ping only on
SYNC0-1 according to 0x0981.(2:1) for debug-
ging
This bit is self-clearing, always read 0.
r/(w) r/(w) 0
Table 100: Register 0x0981 (SYNC Out Activation)
Note
Write to this register depends upon setting of 0x0980.0.
