1 vSS!ValidFrame = 1
Sync Frame Indicator Channel B — protocol related variable: vRF!Header!SyFIndicator channel B
0 vRF!Header!SyFIndicator = 0
1 vRF!Header!SyFIndicator = 1
Null Frame Indicator Channel B — protocol related variable: vRF!Header!NFIndicator channel B
0 vRF!Header!NFIndicator = 0
1 vRF!Header!NFIndicator = 1
Startup Frame Indicator Channel B — protocol related variable: vRF!Header!SuFIndicator channel B
0 vRF!Header!SuFIndicator = 0
1 vRF!Header!SuFIndicator = 1
Syntax Error on Channel B — protocol related variable: vSS!SyntaxError channel B
0 vSS!SyntaxError = 0
1 vSS!SyntaxError = 1
Content Error on Channel B — protocol related variable: vSS!ContentError channel B
0 vSS!ContentError = 0
1 vSS!ContentError = 1
Boundary Violation on Channel B — protocol related variable: vSS!BViolation channel B
0 vSS!BViolation = 0
1 vSS!BViolation = 1
Channel first valid received — This status bit applies only to receive message buffers assigned to the
static segment and to both channels. It indicates the channel that has received the first valid frame in
the slot. This flag is set to 0 if no valid frame was received at all in the subscribed slot.
0 first valid frame received on channel A, or no valid frame received at all
0 first valid frame received on channel B
