Channel Assignment - Siemens SIMADYN D Manual

Hex.
Value
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).
2 Communications partner not ready or the communications link
was physically interrupted (refer to YTS for more detailed
information).
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.
Only for transmitters: Data cannot be transmitted. Normally, in
4
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).
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).
6 Inconsistent data (subrack coupling: when shutting down the
master subrack)
7 Only select transmitters: channel occupied. Another function
block is presently transmitting.
Only multiple receivers: Reception erroneous. Data read-out
8
took too long; in the meantime, the transmitter has already
written new data into the channel.
Still being initiated. Transmit/receive operation was therefore not
9
able to be started.

General
information
System- and communication configuring D7-SYS - SIMADYN D
Edition 12.2003
Significance
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.
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:
Communications configuring
Counter-measure
Correct configuring.
Check coupling partner, cables
and connector.
Activate the communications
partner
Configure the transmitter to be
slower or the receiver to be
faster.
Configure the receiver to be
slower or the transmitter faster.
None (proceed with new
initialization)
All select transmitters can
coordinate via the enable input.
Configure receivers in a faster
(higher-priority) sampling time.
