Frame ID (min/max)
The frame ID contains the number of the slot in which the frame is transmitted. Each
frame ID occurs only once during a FlexRay cycle.

To trigger on a frame ID, you have to define a condition and one or two identifier pat-
terns. The second identifier pattern is required to specify a range with conditions "In
range" and "Out of range". In binary format, use the following characters: 1; 0; or X
(any bit). The use of X is restricted to the conditions "Equal" and "Not equal". If the
identifier is not relevant for the trigger setup, set it to "Off".
The maximum length of the pattern is 11 bit.
The bit pattern editor helps you to enter the pattern in any format, see Chapter 13.1.7,
"Bit pattern editor" , on page 493.

Payload length (min/max)
The payload length contains the number of words transmitted in the payload segment.
Information is transmitted in 2-byte words, so the number of data bytes in the payload
segment is twice the payload length.

To trigger on the payload length, you have to define a condition and one or two num-

Cycle count (min, max), Step
The cycle count contains the number of the current FlexRay cycle.
