9.8 Block search Type 5 (SERUPRO)
Activation
SERUPRO is activated via the HMI. SERUPRO is operated using the "Prog.Test Contour"
softkey.
SERUPRO uses REPOS to approach the target block.
Chronological sequence of SERUPRO
1. Via HMI, softkey "Pog. test contour" and the search target are operated.
2. The NC now automatically starts the selected program in "Program test" mode.
– In this mode, axes are not traversed.
– Auxiliary functions $A_OUT and the direct PLC IO are output.
– The auxiliary functions of the target block are not output.
3. The NC stops at the beginning of the target block, deselects the program test internally,
and displays the Stop condition "Wait: Search target found".
4. If the user-specific ASUB "PROG_EVENT.SPF" is available, it is started automatically.
5. Repositioning is performed with the next NC start (REPOS).
The REPOS operation is performed via a system ASUB and can be extended using the
"Editable ASUB" function.
Boundary conditions for block search SERUPRO
The SERUPRO function may only be activated in "AUTOMATIC" mode and may only be
aborted in program state (channel state RESET).
If in normal mode only the PLC starts commonly several channels, then this can be simulated
by SERUPRO in each channel.
With machine data setting:
MD10708 $MN_SERUPRO_MASK, bit 1 = 0,
alarm 16942: "Channel %1 Start program command action %2<ALNX> not possible"
aborts the simulation if part program command START is used.
Machine data:
MD10707 $MN_PROG_TEST_MASK
allows shutdown in the stopped state and has no effect on the SERUPRO operation. The
default setting allows program testing to be deactivated only in the RESET state.
Note
After program testing has been deactivated, a REPOS operation is initiated that is subject to
the same restrictions as a SERUPRO approach operation. Any adverse effects can be inhibited
using an ASUB.
