Toggle bit data transfer
The signal shows that the device has accepted the data
or the data fragment (see also Toggle bit data rejection).
0→1 Data have been accepted
1→0 Data have been accepted
0x02
Toggle bit data rejection
The device has rejected the acceptance of the data or the
data fragment (see also Toggle bit data acceptance).
0→1 Data have been rejected
1→0 Data have been rejected
0x03
New input toggle
Toggle bit signals whether new input data is present.
0→1 New result
1→0 New result
0x04
5-bit alignment
5 fill bits
0x05
Error code
Cause of error if a message is rejected.
0
No error
1
Receive Buffer Overflow
2
Sequence error, i.e. an error was detected with
the fragment number transferred from the control,
the number of remaining fragments or the frag-
ment size.
3
No available command-interpreter buffer
4
Invalid maximum fragment length
5
Invalid fragment size
6
No provision made for further fragments although
additional fragments were sent.
0x06
Input data length
Data length of the actual entry information.
Comments:
Data reset does
not
affect the output data toggle bits.
If fragmentation is used, it must always be ensured on the application side for each fragment that is to be
transferred that the output data of input fragmentation object 0x2400 is set before toggle bit is toggled in an
input data object.
