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.

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.
