Single-Block Behavior In Mode Group With Type A/B - Siemens SINUMERIK 828D Function Manual

K1: Mode group, channel, program operation, reset response
9.12 Single block
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

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
In one channel (KS) in a mode group, the user should select single-block (NST DB21 ... DBX0.4 (activate single
block)). Single-block type A or B refers to other channels (KA) of a mode group.
