Event Class 5 (05H):
“Error while processing CPU job”
Event No. Event Remedy
(05)01H Current job aborted as a result of CP
restart. No remedy is possible at POWER ON. When
reparameterizing the CP from the
programming device, before describing an
interface you should ensure there are no
more jobs running from the CPU.
(05)02H Job not permitted in this operating mode of
the CP (e.g. device interface not
parameterized). Parameterize the device interface.
(05)0EH
•
Invalid message frame length
or
•
The parameterized end-of-text
characters did not occur within the
maximum permissible length.
•
The message frame is > 200 bytes in
length. Select a shorter message frame
length.
or
•
Add the end-of-text characters at the
place you want in the send buffer.
(05)17H Transmission length > 200 bytes is too
large for the CP Split the job up into several shorter jobs.
(05)1DH Send/receive job interrupted by:
•
Communication block reset
•
Reparameterization
Repeat the call for the communication block.
(05)22H A new SEND job has been started,
although the old job has not yet been
completed. Only start the new SEND job when the old
job has been completed with DONE or
ERROR.
Event Class 7 (07H):
“Send error”
Event No. Event Remedy
(07)01H With 3964(R) only:
Transmission of the first repetition:
•
An error was detected during
transmission of the message frame, or
•
The partner requested a repetition by
means of a negative acknowledgment
code (NAK).
A repetition is not an error, but it can be an
indication that there are disturbances on the
transmission line or that the partner device is
behaving incorrectly. If the message frame
still has not been transmitted after the
maximum number of repetitions, an error
number describing the first error that
occurred is output.
(07)02H With 3964(R) only:
Error during connection setup:
After STX was sent, NAK or any other code
(except for DLE or STX) was received.
Check for malfunctioning of the partner
device, possibly using an interface test
device switched into the transmission line.
(07)03H With 3964(R) only:
Acknowledgment delay time exceeded:
After STX was sent, no response came
from the partner within acknowledgment
delay time.
The partner device is too slow or not ready
to receive, or there is a break on the send
line, for example. Identify the malfunctioning
of the partner device, possibly by using an
interface test device switched into the
transmission line.
