Application Note DK9222-0213-0063
The following table gives an overview about the settings of the Video Binloop, which are not configured in TwinCAT but in the
external device.
SMPTE
Setting Description Value
Mode Determines whether the SMPTE Interface will
generate timecode, or read external timecode.
Gen
Frame rate
The frame rate in which SMPTE is generated. 23,976
Preroll Time Initial time of SMPTE generator when it is first
enabled.
Start Time Time that SMPTE generator returns to after it reaches
the end time (when looping)
00:00:00.00
End Time Time when SMPTE generator either stops or loops
back to start time.
Loop Mode Determines whether SMPTE generator loops
continuously from start to end time.
enabled
Powerup Mode Determines whether SMPTE is enabled or disabled
when Binloop powers up.
Start
Restart Mode Determines how SMPTE generator responds when it
is told to start again. It can either restart or ignore
the start command.
enabled
Idle Mode Determines if SMPTE output is muted or active when
the SMPTE Interface is idle.
SMTPE Active
Determines how long SMPTE reader will free-wheel
when external SMPTE is lost.
disabled
Output Level Configures the voltage level (in dB) of the SMPTE
output.
4 dBV
00:00:00.00
00:00:00.00
Self Gen Mode
Table 3 Binloop parameters (from manual at Alcorn McBride Inc. website) are not configured in TwinCAT
Note:
Theoretically the information is readable at all frame rates, but the sample program is designed for 24 fps and has not
been tested for other frame rates. Furthermore only the time information is read out, not the user bits, the flags and other
information transmitted with the frame.
