Boundary conditions for block search SERUPRO
The SERUPRO function may only be activated in "AUTOMATIC" mode and may only be aborted in program
status (channel status RESET).
If in normal mode only the PLC starts commonly several channels, then this can be simulated by SERUPRO in
each channel.
If 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_SERUPRO_TEST_MASK
allows program testing to be deactivated in the stopped state without the SERUPRO operation being affected.
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.
Controlling SERUPRO behavior
Machine data:
MD10708 $MN_SERUPRO_MASK
can be used to control the SERUPRO behavior as follows:
Bit Valu Meaning
e
0 0 The search stops at M0.
1 The search is not stopped for M0.
1 0 The search is interrupted for command START with alarm 16942.
1 Command START starts the specified channel.
Caution!
Without any special measures, the axes physically traverse (move) in the started
channel. The user is solely responsible in preventing the axes from undesirably
traversing, e.g. by activating "Program test".
2 0 The SERUPRO function group is disabled.
1 The SERUPRO function group is enabled. The START command starts the specified
channel in the "Program test" mode.
3 0 All channels that find the search target (also for self-acting SERUPRO) end SERUPRO
at the same time.
1 SERUPRO ends as soon as the search target has been found. No further
synchronization operations take place in the channels started by SERUPRO.
