2.8 Single block
Mode Group, Channel, Program Operation, Reset Response (K1)
2-120 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Boundary conditions
The following restriction applies to decoding single block SBL2:
• Block search approach blocks
• Block not in ASUB; DISPLOF, SBLOF
• Non-reorganizable and non-repositionable blocks
• Blocks that are not generated in the interpreter, e.g., intermediate blocks
2.8.4 Single-block behavior in mode group with type A/B
Classifying channels
One mode group channel must be classified as a single-block control channel (KS), while the
other mode group channels must be classified as dependent channels (KA) via interface
signal. Type A or type B single-block behavior can be selected for KA channels.
Type A determines Stop (analogous to STOP key).
Type B determines Stop (analogous to stop at block limit).
Channel classification
The user should select single-block (DB21.DBB0.BIT4) in one channel (KS) in a mode
group. Single-block type A or B refers to other channels (KA) of a mode group.
Channel n KA
Channel 2 KA
Channel 3 KAChannel 1 KS
...
Mode group
Behavior can be selected via type A or type B
Fig. 2-15 Channel classification for single block in the mode group
Type A, DB11 DBX1.7=1
- 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 (analogous to STOP key).
- All channels are stopped (deceleration phase of all KAs).
