6.4.3 List Execution Status
In addition to the list status values, see Chapter 6.4.2
”List Status”, page 107, list execution status values
are provided.
These can be queried by the control command
get_status.
• BUSY list execution status
The BUSY list execution status is set when:
– the RTC6 PCIe Board currently processes one of
the two lists
– a list has been paused by the control
commands pause_list or stop_list
The BUSY list execution status is not set when a
list has been paused by the list command
set_wait (is set again by a subsequent
release_wait).
• PAUSED list execution status
The PAUSED list execution status is set when
processing of the list has been paused by
pause_list, stop_list or set_wait. It is reset by a
subsequent restart_list or release_wait, see also
Chapter 6.4.5 ”Interrupting Lists for
Synchronization of Processing”, page 110.
• INTERNAL-BUSY list execution status
The INTERNAL-BUSY list execution status is set
when the RTC6 PCIe Board is busy with executing
a control command, which needs more than
10 µs for executing a scan movement (for
example, goto_xy or possibly set_offset) or
while a home jump or home return is executed
(with set_wait, set_end_of_list or release_wait,
if the home jump mode has been previously
activated by home_position or
home_position_xyz).
• HEAD BUSY status
Operating status for SCANahead systems.
Refer to “excelliSCAN Scan Heads – Functional
Principle of SCANahead Servo Control and
Operation by RTC6 Boards” Manual,
Chapter 3.1.4 ”Differences with Transmitted
Signals: New Status Value HEAD_BUSY”, page 15.
Notes
• The INTERNAL-BUSY list execution status and the
BUSY list execution status cannot be set at the
same time.
• With the RTC6 PCIe Board, the
BUSY list execution status is also available as
BUSY OUT signal at:
– LASER Connector,
see Figure 17
– EXTENSION 1 socket connector,
see Figure 22
– MARKING ON THE FLY
socket connector,
se
e Figure 25
• Some control commands are ignored (not
executed), when the BUSY list execution status
and/or INTERNAL-BUSY list execution status are
set (for example, auto_cal, goto_xy,
load_correction_file) or – with set
INTERNAL-BUSY list execution status – are only
executed with delay after the
INTERNAL-BUSY list execution status has been
reset again (for example, execute_list_pos,
set_offset).
