Monitoring Processing-On-The-Fly Corrections - Scanlab RTC6 PCIe Board Installation And Operation Manual

8.6.9 Monitoring
Processing-on-the-fly
Corrections
The Image Field boundaries might be reached, if:
• A Processing-on-the-fly user program is not
optimized for the motion of the workpiece or
scan system
• Considerable unintended change of workpiece or
scan system speed occurs during a
Processing-on-the-fly operation
Because the RTC6 PCIe Board clips coordinate values
at the boundaries to prevent unallowed values, this
could cause some parts of the to-be-marked pattern
to not be scanned.
To allow user programs to monitor
Processing-on-the-fly applications, the
RTC6 PCIe Board sets internal error bits
(Bit #0...Bit #3) if the Image Field
exceeded (and coordinate values get clipped). These
can be read out by get_marking_info.
To avoid boundary exceedance, you should
repeatedly call get_marking_info
normal operation of your Processing-on-the-fly
application and modify your user program
accordingly.
