Ctrl Command stop_trigger
Function Resets (to Busy = 0) the measurement session status that can be queried by
measurement_status.
Call stop_trigger()
Comments • stop_trigger is only needed if a measurement session has been started by
set_trigger/set_trigger4/set_trigger8, but not subsequently terminated by:
– set_trigger( Period = 0)
– set_trigger4( Period = 0)
– set_trigger8( Period = 0)
Here, you can reset the measurement session status even when no list is active (see
comments at set_trigger).
• stop_trigger is not executed (get_last_error return code RTC6_BUSY ), if:
– the BUSY list execution status is set
– the INTERNAL-BUSY list execution status is set
• stop_trigger is even executed, if:
– a list has been paused by set_wait (PAUSED list execution status set)
RTC4RTC6 New command.

Short List
Command
store_encoder
Function Stores the current counts of the two RTC6 encoder counters in a cache on the RTC6.
Call store_encoder( Pos )
Parameters Pos Storage position.
As an unsigned 32-bit value.
• Bit #0 = 0: The counter values are saved to storage position 0.
• Bit #0 = 1: The counter values are saved to storage position 1.
Comments • store_encoder can be used, for instance, to determine the exact number of encoder
increments occurring within a specific list-processing period. Here, you could begin the
command list by saving the counts in storage position 0 by store_encoder(0) . At the
end of the command list, you could save the counts to storage position 1 by
store_encoder(1) and subsequently retrieve by read_encoder.

”Synchronization by Encoder Signals”, page 298.
