QUERIES REGARDING SCHLAFHORST’S AUTOCONER 238


WINDING UNIT COMPUTER & CLEARER CARD exchange information in terms of
software codes.

Starting from the first event to last event i.e. from fresh cone to the finished cone

Software codes & their sequence of different events such as,

· Initial parameter settings of Informator as well as Loepef’s control box & their software codes
· Input signal’s codes from sensor & it’s sequence
· Codes during splicing cycle & it’s sequence
· Codes during all types of fault cut & it’s sequence
· Codes during Doff over & it’s sequence



2 What is the Clearer center (in machine frame)?

3 From where Evaluation circuit (CLEARER) receives supply? How many different

Power supplies are used in CLEARER? Details about type of connectors used, potentials on

each pin? Power supplies current & voltage rating?

4. Details such as cable wiring between schlafhorst’s informator & its WINDING UNIT

COMPUTER

5 Since all the winding parameters are transmitted by INFORMATOR to the WINDING UNIT

COMPUTER.

Means of communication between these two. i.e. through RS-232, RS-485 or some other way?

Software codes corresponding to different winding parameters & at which baud rate codes

are transmit/receive? Connector (terminal) pins used for this communication.










6 Following output signals are transmitted by WINDING UNIT COMPUTER to CLEARER

circuit

RNABG-clearer ‘ZERO’ tuning

IMPSP- Pulse interlock-clearer

STR-R- transfer signal – clearer

Significance of above signals. What purpose they serve?


7 CLEARER receives additional information (winding parameters) in from of software codes

serially from WINDING UNIT COMPUTER


In which sequence above information (software codes) are received from WINDING UNIT

COMPUTER to CLEARER. Whether Software codes are in BYTE (8 bit) or WORD (16 bit)

Format?


Details about those winding parameters & their corresponding software codes


8. EYC curve setting sent by whom?


9 CLEARER send this 5 signal’s software codes serially to WINDING UNIT COMPUTER

DIS- Thick place cut signal

DUS- Thin place cut signal

DOS-Double end cut signal

SFS- static yarn signal

DFS- dynamic yarn signal

So the software codes for above signals & their sequence & their format BYTE(8 bit) or
WORD (16 bit)?





10. Frequency (clock) of MICROPROCESSOR for code execution in WINDING UNIT

COMPUTER?

11. How many spindles one INFORMATOR can handle?


12. Is there any signal to identify SPLICE check?


13. Data transmission & receiving between CLEARER & WINDING UNIT COMPUTER is

On polling or on interrupt?
