Control Commands And List Commands - Scanlab RTC6 PCIe Board Installation And Operation Manual

6.1.2 Control Commands and
List Commands
The RTC6 command set consists of:
• Control commands
• List commands
Control commands are executed immediately.
They are used, for instance, for initializing,
controlling execution of lists, setting some general
parameters, or for directly controlling the laser and
scan head.
Before list commands can be sent to the
RTC6 PCIe Board, a control command must define
the input pointer to which subsequent
list commands are transferred. This corresponds to
opening a list, see Chapter 6.4.1 "Loading Lists",
page 105.
List commands sent to the RTC6 PCIe Board
afterwards are not executed immediately. They are
stored in the RTC6 List Memory
processed in real time only after the list has been
started.
List commands include Jump
[*]mark[*] Commands and
as commands for setting various scanning
parameters such as laser power, jump speed and
mark speed.
Some of the list commands are so called short
list commands. These do not require the full
10 µs clock cycle for command execution. They are
executed along with the next list command, one
directly after the other within a single
10 µs clock cycle. A control command cannot be
executed in between. The total list execution time is
thereby reduced.
Short list commands include list_jump_pos,
etc. With a Polyline, for example, the laser power can
be set individually for each vector by the short
write_da_x_list
list command
(the laser remains on).

Some commands exist in two versions: as a
list command and as a control command. Among
these dual-version commands are the I/O commands.
All RTC6 commands are described in detail in
Chapter 10 "RTC6 Commands".
