Additional Text
With this feature it is possible to read additional text if
bit 10, Additional text available, is true in Basic charac-
teristics.
To read out additional text, the parameter command
(PKE) must be set to F hex, see Databytes.
The index-field is used for pointing out which element
to be read. Valid indexes are in the range of 1 through
254. The index must be calculated after the following
equation:
Index = Parameter value + 1 (see table below).
Value Index Text
0 1 English
1 2 Deutsch
2 3 Français
3 4 Dansk
4 5 Espanol
5 6 Italiano
Example:
In this example, the Master reads additional text in pa-
rameter 001, Language. The telegram is set up to read
datavalue [0] which corresponds to English. The fol-
lowing telegram must be sent to the VLT frequency
converter:
STX LGE ADR PKE IND PWE
HIGH
PWE
LOW
PCD1 PCD2 BCC
02 0E 01 F0 01 00 01 00 00 00 00 XX XX XX XX XX
STX = 02 Start byte
LGE = 0E Length of the remaining telegram
ADR = Send the VLT frequency converter on Ad-
dress 1, Danfoss format
PKE =
F001; F in the PKE field indicates a Read
text and 01 indicates parameter number
001, Language.
IND = 0001; 1 indicates that text to parameter val-
ue [0] is required
The response from the VLT frequency converter will
be:
STX LGE ADR PKE IND PVA PCD1 PCD2 BCC
02 11 01 F0 01 00 01 454E 474C 4953 48 XX XX XX XX XX
PKE =
F001; F is the response for Text transfer and
01 indicates parameter number 001, Lan-
guage.
IND = 0001; 1 indicates that index [1] is sent
PVA = 45 4E 47 4C 49 53 48
E N G L I S H
The parameter value channel is now set up to a visible
string, which returns an ASCII character for each letter
in the index name.
