Transmit Message Buffer Slot Status Description
This section describes the slot status structure for transmit message buffers. Only the TCA and TCB status
bits are directly related to the transmission process. All other status bits in this structure are related to a
receive process that may have occurred. The content of the slot status structure for transmit message
buffers depends on the channel assignment as given by Table 3-84.
11
SEB
Syntax Error on Channel B — protocol related variable: vSS!SyntaxError channel B
0 vSS!SyntaxError = 0
1 vSS!SyntaxError = 1
10
CEB
Content Error on Channel B — protocol related variable: vSS!ContentError channel B
0 vSS!ContentError = 0
1 vSS!ContentError = 1
9
BVB
Boundary Violation on Channel B — protocol related variable: vSS!BViolation channel B
0 vSS!BViolation = 0
1 vSS!BViolation = 1
8
CH
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
7
VFA
Valid Frame on Channel A — protocol related variable: vSS!ValidFrame channel A
0 vSS!ValidFrame = 0
1 vSS!ValidFrame = 1
6
SYA
Sync Frame Indicator Channel A — protocol related variable: vRF!Header!SyFIndicator channel A
0 vRF!Header!SyFIndicator = 0
1 vRF!Header!SyFIndicator = 1
5
NFA
Null Frame Indicator Channel A — protocol related variable: vRF!Header!NFIndicator channel A
0 vRF!Header!NFIndicator = 0
1 vRF!Header!NFIndicator = 1
4
SUA
Startup Frame Indicator Channel A — protocol related variable: vRF!Header!SuFIndicator channel A
0 vRF!Header!SuFIndicator = 0
1 vRF!Header!SuFIndicator = 1
3
SEA
Syntax Error on Channel A — protocol related variable: vSS!SyntaxError channel A
0 vSS!SyntaxError = 0
1 vSS!SyntaxError = 1
2
CEA
Content Error on Channel A — protocol related variable: vSS!ContentError channel A
0 vSS!ContentError = 0
1 vSS!ContentError = 1
1
BVA
Boundary Violation on Channel A — protocol related variable: vSS!BViolation channel A
0 vSS!BViolation = 0
1 vSS!BViolation = 1
