RTC4RTC6 Unchanged functionality. In addition: increased value range.
In RTC4 Compatibility Mode, the RTC6 multiplies the specified value for Delay by 16.
The allowed value range decreases accordingly.
RTC5RTC6 Unchanged functionality.
Version info Available as of DLL 600, OUT 600, RBF 600.

Command
simulate_ext_start
Ctrl Command simulate_ext_start_ctrl
Function Causes a simulated External Start.
Call simulate_ext_start_ctrl()
Comments • For External Starts, see Section ”External Start”, page 290.
• The start trigger for the start occurs only after a track delay previously set by
set_ext_start_delay, set_ext_start_delay_list or simulate_ext_start.
Track delays are deactivated by initialization (with load_program_file), by external
stops and by stop_execution. They can also be deactivated with set_control_mode
(Bit #2). External Starts initiated by simulate_ext_start_ctrl or by an external start
signal, but whose execution has been postponed according to the specified track delay,
are placed in a queue that accommodates up to 8 starts. In contrast to
simulate_ext_start, simulate_ext_start_ctrl does not cancel the previous queue.
• A start trigger initiated by simulate_ext_start_ctrl or by an external start signal does
only trigger a start if it does not coincide with the output of a list (otherwise, Bit #11
of the get_startstop_info return value gets set).
• The simulate_ext_start_ctrl command alone does not cause an encoder reset. But if
accordingly set with set_control_mode( Bit #9 ), a start trigger initiated by
simulate_ext_start_ctrl, simulate_ext_star
t or by an external start signal causes an
enc
oder reset if the start trigger is preceded by one of the Processing-on-the-fly
commands set_fly_x, set_fly_y, set_fly_2d or set_fly_rot.
• simulate_ext_start_ctrl can be disabled by set_control_mode( Bit #4 = 1 ) or
set_control_mode_list( Bit #4 = 1 ).
• As of version DLL 609, OUT 609, RBF 614, the following applies: provided that a start
is allowed, simulate_ext_start_ctrl waits 30 µs before it returns. This closes a potential
timing gap (with get_status) between command call and actual start.
RTC4RTC6 New command.
