Error in the SFB parameter configuration"
W#16#0703
Only for 3964(R):
Confirmation time (QVZ) exceeded:
After the transmission of STX the
partner did not respond within the
confirmation delay time.
The partner device is too slow or not ready to
receive, or the data link is interrupted. Prove
the faulty behavior of the partner if required by
hooking up an interface tester to the data link.
W#16#0704
Only for 3964(R):
Abortion by the partner:
One or several characters were
received from the partner while the
send operation was in progress.
Check whether the partner also indicates an
error because possibly it has not received all
of the transmitted data (for example, due to an
interrupted data link), or because fatal errors
are pending, or the behavior of the partner
device is faulty. Prove the faulty behavior of
the partner if required by hooking up an
interface tester to the data link.
W#16#0705
Only for 3964(R):
Negative confirmation while
transmission was in progress
Check whether the partner also indicates an
error because possibly it has not received all
of the transmitted data (for example, due to an
interrupted data link), or because fatal errors
are pending, or the behavior of the partner
device is faulty. Prove the faulty behavior of
the partner if required by hooking up an
interface tester to the data link.
W#16#0706
Only for 3964(R):
End-of-transmission error:
• The partner has rejected the
message frame at the end with
NCC or any character (except
DLE)
• The confirmation character (DLE)
was received too early.
Check whether the partner also indicates an
error because possibly it has not received all
of the transmitted data (for example, due to an
interrupted data link), or because fatal errors
are pending, or the behavior of the partner
device is faulty. Prove the faulty behavior of
the partner if required by hooking up an
interface tester to the data link.
W#16#0707
Only for 3964(R):
End-of-transmission confirmation delay
time / response watchdog time was
exceeded:
The partner did not respond within the
QVZ after the connection went down
via DLE ETX.
The partner device is too slow or disrupted.
Prove the faulty behavior of the partner if
required by hooking up an interface tester to
the data link.
W#16#0708
Only for ASCII drivers:
The waiting time on XON has expired.
The communication partner is disrupted, too
slow or switched offline. Check the
communication partner or change the
parameters if required.
W#16#0709
Only for 3964(R):
Could not establish a connection, the
permitted number of startup attempts
was exceeded.
Check the interface cord or the transmission
parameters.
Also check in the partner whether the
parameters for the receive function between
CPU and CP have been correctly assigned.
W#16#070A
Only for 3964(R):
Could not transmit data, the permitted
number of attempts to transmit was
exceeded.
Check the interface cord or the transmission
parameters.
W#16#070B
Only for 3964(R):
Initialization conflict cannot be solved
because both partners are set to high
priority.
Change the parameters.
