Data word Name Direction Type of signal
013.00 − 07 Individual/following block PLC
→
NC static
Switching between following and individual block operation. (This signal is
ORed with the "Individual/following block" signal from the DB15.)
Effect in the NC: A program is processed continuously (following block) or
block by block (individual block):
0 = following block
1 = individual block
Data word Name Direction Type of signal
013.08 − 15 Hide block PLC
→
NC static
With this signal, the "Hide block" function can be switched on or off. (This
signal is ORed with the "Hide block" signal from the DB15).
Effect in the NC: Blocks with a preceding "/" are hidden, i.e. they are not ex-
ecuted:
0 = Hide block inactive
1 = Hide block active
Data word Name Direction Type of signal
014.00 − 07 Return PLC
→
NC static
The signal (a bit per NC channel) makes it possible to return ("Return") to the
programmed path. During this process, the return movement is not limited
by blocks without geometry, i.e. individual S/T/M/Q functions, coordinate
shifts and G21 blocks are permitted and do not result in the limitation of the
return memory.
All other G functions, which are not pure interpreter functions, (
¶ 91)result
in the limitation of the return memory as usual. During the return, M func-
tions are output as they have been programmed if no other customer−speci-
fic solution has been planned. G21 and Q functions are ignored during the
return.
Effect in the NC: When the signal is set, the NC processes the blocks in the
prebuffer in reverse order. During this process, traversing blocks are output
with negative speed.
