SERUPRO approach
Approach to the starting point of the target block during a block search in SERUPRO test
mode.
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.
For 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.
Basic logic functions: Mode group, channel, program operation, reset response (K1)
