19.6.2 Signals from the mode group (DB11)
DB11
DBX1.7 Single block type A
Edge evaluation: No Signal(s) updated:
Signal state 1 or
edge change
0 → 1
DB11 DBX1.7 set and DB11 DBX1.6 not set: Response across modes
• All channels are stopped.
• All channels receive a start (start key).
• Channel KS stops at the end of the block (due to single-block)
• Channels KA receive a STOP command. (comparable to the STOP KEY).
• All channels are stopped. (deceleration phase of all KAs)
(If DB11 DBX1.6 and DB11 DBX1.7 are set simultaneously, it is impossible to determine which
single block type is required. The control then assumes: No single block across mode groups).
Signal state 0 or
edge change
1 → 0
If DB11 DBX1.7 is not set and DB11 DBX1.6 is set, then it is single block type B.
(If DB11 DBX1.6 and DB11 DBX1.7 are not set, it is impossible to determine which single block type
is required. The control then assumes: No single block across mode groups).
