5.4. Read tacho identifier
Identification data are read only.The identifier is followed by two parameters: Command parameter „I“
(identification) and either parameter „T“ (type and software version), or “D“ (date and hardware version).
Read device type and software version:
Identifier=35, Typ=TA134, software version=01
Command: <STX>35IT<ETX>
Response: <STX>35TA134 01<ETX><CR>
Read data and version number:
Identifier=35, data=02.10.97, version number=1
Command: <STX>35ID<ETX>
Response: <STX>35021097 1<ETX><CR>
6. Error signals in data transfer
In case the tachometer receives a void data protocol by PC (for example not existing line or letters instead of
numbers) the tachometer gives a corresponding error signal, provided it is still in operating status. To get an
error signal in case of error, at least control token <STX> and identifier have to be correct. If not, TA134 is not in
operating status anymore and therefore not in a position to return an error signal to the PC.
If no reply neither an error signal is received upon PC request it is a fatal error. As previously mentioned, either
control sign <STX> or identifier are missing or there is no data congruence of PC and TA 134 interface
parameters. Should these however be correct it is a hardware or data line error.
Standard error signal structure:
<STX> identifier line mode <CAN> error number <ETX> <CR>
Example: Identifier=35, line=09 (void line), error signal=2
<STX>3509R<CAN>2<ETX><CR>
Detailed error explanations:
Error 1: Format error (incorrect <ETX> position. This signal is given in case the
data format was not kept during programming (for example during parame
terization of a limit only 5 digits instead of 6 were transferred).
Error 2:
Line (position) not existing or separating line
Error 3:
Parameter error (void data in protocol). Example: Limit value not only
consisting of numbers but also of void tokens, or a parameter is beyond
the permitted range.
