Edition 12.2003
Hex.
Value
Significance Counter-measure
0
No fault/error, data transfer was successful.
1
Block was permanently disabled after initialization due to a
configuring error or after an internal error (refer to the
communications error field or YTS output for detailed
information).
Correct configuring.
2
Communications partner not ready or the communications link
was physically interrupted (refer to YTS for more detailed
information).
Check coupling partner, cables
and connector.
3
Communications partner is not transmitting/receiving (depending
on the enable input of the communications partner). The
function block is not transmitting/receiving because the
communications partner has signaled that it is not transmitting
data.
Activate the communications
partner
4
Only for transmitters: Data cannot be transmitted. Normally, in
the handshake/select mode: The communications partner has
still not read-out the last data; seldom in the refresh mode:
Communications partner is presently reading).
Configure the transmitter to be
slower or the receiver to be
faster.
5
Only for receivers: No new data could be received (the
communications partner hasn't transmitted any new data since
the last data was received).
Configure the receiver to be
slower or the transmitter faster.
6
Inconsistent data (subrack coupling: when shutting down the
master subrack)
None (proceed with new
initialization)
7
Only select transmitters: channel occupied. Another function
block is presently transmitting.
All select transmitters can
coordinate via the enable input.
8
Only multiple receivers: Reception erroneous. Data read-out
took too long; in the meantime, the transmitter has already
written new data into the channel.
Configure receivers in a faster
(higher-priority) sampling time.
9
Still being initiated. Transmit/receive operation was therefore not
able to be started.
Table 3-92
Fault/error cause
In the handshake mode, these numbers can sporadically occur which is
quite acceptable. This is because full synchronization between the
communications partner is not always possible. Receivers and
transmitters should operate approximately in the same cycle.
In the refresh mode, these numbers should not occur if the transmitter is
always faster than the receiver.
3.24.3.2 Channel
assignment
The area is only used by the CCC4 and CDC4 function blocks. In this
case, a number indicates which channel is involved with the error
(bits 0-7). As the channel marshalling block can process up to five
channels, the numbering is as follows:
