*) The Activate input fragmentation attribute is a parameter. The value of the parameter can be set via the
configuration assembly.
Data acceptance (toggle bit)
The signal shows that the sensor has accepted the data or the data fragment (see also Toggle bit data re-
jection):
0 > 1: Data has been accepted
1 > 0: Data has been accepted
Data rejection (toggle bit)
The sensor has rejected the acceptance of the data or the data fragment (see also Toggle bit data accep-
tance).
0 > 1: Data has been rejected
1 > 0: Data has been rejected
Error code
Cause of error if a message is rejected:
0: No error
1: Receive buffer overflow, e.g., if the data length to be transferred is greater than the data buffer of the
command interpreter.
2: Sequence error, i.e. an error was detected with the fragment number transferred from the control, the
number of remaining fragments or the fragment size.
3: No receive buffer, i.e., there is no free receive buffer of the command interpreter present.
4: Invalid maximum fragment length, i.e., if the fragmentation is activated, the maximum fragment length is
less than the data length.
5: Invalid fragment length, i.e., if fragmentation is activated, the current fragment length is less than the cur-
rent data length.
6: Invalid number of remaining fragments, i.e., with activated fragmentation, the remaining fragments are
not consistent.
NOTICE
The following sequence diagram shows with examples how the Data acceptance ‚ Data rejection
and Error code attributes are connected.
