Event class 6 (06H):
"Error when processing a partner job" only for RK 512
Event no. Event text Remedy
(06)0EH Synchronous fault of partner
• New (continuation) command message
frame received before response message
frame was sent.
• 1. command message frame expected and
continuation message frame came.
• Continuation command message frame
expected and 1st message frame came.
This error may be reported after your own automation
system is restarted in the case of long message frames
or when the partner is restarted. These cases
represent normal system start-up behavior.
The error can also occur during operation as a
consequence of error statuses only recognized by the
partner.
Otherwise, you have to assume an error on the part of
the partner device. The error may not occur in the case
of requests < 128 bytes.
(06)0FH DB locked by coordination function In local program: Reset the interprocessor
communication flag after the last transmission data
was processed.
In the partner program: Repeat the request
(06)10H Message frame received too short (length < 4
bytes in the case of continuation or response
message frames or <10 bytes in the case of
command message frames)
Check for malfunction on partner device, possibly by
using an interface test device interconnected in the
data link.
(06)11H Message frame length and length specified in
message frame header are not the same.
Check for malfunction on partner device, possibly by
using an interface test device interconnected in the
data link.
(06)12H Error while sending the (continuation) response
message frame. An associated procedure error
number has been entered in STATUS
immediately beforehand.
See remedies for the error number entered
immediately beforehand in STATUS.
Event class 7 (07H):
"Send error"
Event no. Event Remedy
(07)01H Sending of the first repetition:
• An error was detected when transmitting the
message frame, or
• The partner requested a repetition by means of
a negative acknowledgment character (NAK).
A repetition is not an error, but it can indicate that
there is interference on the data link or the partner
device has malfunctioned. 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 3964(R) only:
Error establishing connection:
After STX was sent, NAK or any other character
(except for DLE or STX) was received.
Check for malfunction of the partner device, possibly
by using interface test device interconnected in the
data link.
(07)03H 3964(R) only:
Acknowledgment delay time (QVZ) exceeded:
After STX was sent, partner did not respond within
the acknowledgment delay time.
The partner device is too slow or not ready to
receive, or there is a break in the transmission line,
for example. Check for malfunction on partner
device, possibly by using an interface test device
interconnected in the data link.
