For what are "System flags" used ?

In case of an UWR error message it is a possibility to identify what

causes the error.

How is it possible ?

"System flags" is a submenu in RODIMO: Offline Monitor - Stored data .

For certain conditions the UWR stores in every line of "System flags"

a sample of variables which control the UWR program sequences.

Note: The UWR can store only conditions which are recognized by the

CPU.

How does it work ?

If at least one of the conditions below is true the UWR starts to storesystem flags in every program cycle.

The conditions are:- mechanical brake releases (limit switch signal)- machine speed > "Nullintervall"

(For "Nullintervall" see RODIMO menu:Offline Monitor - Record of variables - Record of variables 1)

- Any UWR error message- Change of main drive contactor condition

Note: After a power reset the "System flag" data are totally erased.

The lines are organized like a shift register, this means a newline erases the oldest line.To check the complete set of system flags it is useful to activatePROTOCOL in menu RODIMO: FILE

Example for the last lines:

Explanation of the variables

1. column: Time after power reset in seconds

2. column: Time after power reset in milli-seconds(decimal 0...65535)

3. column: Machine speed in Sh/h (tacho generator input)

4. column: Machine speed in Sh/h (angle encoder input via RTR)5. column: average machine speed (angle encoder input), decimal6. column: Machine angle (angle encoder input via RTR)7. column: Machine speed acceleration (Sh/h per second)

positive signal = forwardnegative signal = reverse

8. column: F* = machine speed < Nullintervall*F = mechanical break has been locked

9. column: 8* = UWR has switched off the output for terminal 17(normal condition)

7* = UWR has switched off the output for terminal 17(error condition)

*8 = UWR has switched off the output for terminal 19

(normal condition)*7 = UWR has switched off the output for terminal 19

(error condition)

10. column: F* = brake acceleration flag has been switched (terminal 17)

*F = brake acceleration flag has been switched (terminal 19)11. column: F* = RTR has sent softstop signal to main drive by interface

*F = RTR has sent hardstop signal to main drive by interface

12. column: 8* = UWR has switched on the output for main drive contactor (normal condition)7* = UWR has switched off the output for main drive contactor

(error condition)*8 = UWR has switched off the mechanical brake output (normal condition)

*7 = UWR has switched off the output for mechanical brake(error condition)

13. column: 1* = crawl speed admissable2* = reverse crawl speed admissable4* = positioning admissable8* = positioning with reduced speed admissable*F = no UWR 24V power failure

14. column: 1* = limited inch forward admissable2* = limited inch forward with reduced speed admissable4* = inch forward admissable*1 = limited inch reverse admissable*2 = limited inch reverse with reduced speed admissable*4 = inch reverse admissable

15. column: F* = inch forward button has been pressed




20/26

*F = inch reverse button has been pressed16. column: 8* = run button has been pressed

7* = run admissable*8 = automatic start button at LEITSTAND

has been pressed*7 = automatic start function admissable

17. column: 8* = crawl speed button has been pressed7* = crawl speed admissable

F* = positioning admissable (by crawl speed orautomatic start function)

18. column: 8* = security stop button has been pressed7* = emergency stop button has been pressed*8 = No guard is open*7 = machine stop because of an open guard

19. column: 1* = SPS selection: roller wash-up procedure2* = SPS selection: blanket wash-up procedure4* = SPS selection: positioning function8* = SPS selection: change-over procedure for

perfector*1 = roller wash-up procedure admissable*2 = blanket wash-up procedure admissable

*8 = change-over procedure for perfectoradmissable

20. column: 8* = start signal for machine movement activ7* = machine start enabled after start signal*8 = machine start enabled after machine has moved*7 = machine moves

21. column: UWR error number (check error message at LSR screen)22. column: 10 = invalid machine speed

21 = invalid machine speed (overswing during positioning)22 = invalid machine speed (overswing during jogging, inching)30 = invalid machine speed (differenz between command and machine speed)

In the last line of the UWR-testbook the columns of the book are named, this is for making it easier toread the book.

At the end of the so called test book the correction-functions of the input data are shown. Belonging tothe 20 possible SPS-stations, it is shown which of the bits of the digital input boards with safety-relevantinputs are corrected by the UWR.

Note: the UWR compares its input data with the input data of the SPS. If there are differences, the UWRcorrects the input data.This correction is done for five cycles. If there are still differences, than the UWR sends out an errormessage. (e.g.: UWR:SPS Station xy : wrong input data).

example: 0A : 00 10 F0 03

All numbers in hexadecimal code

0AHEX: = station 10 (decimal)00HEX= first byte no correction (0000 0000BIN)10HEX= second byte bit 4 corrected (0001 0000BIN)F0HEX= third byte bit 4, bit 5, bit 6 and bit 7 corrected (1111 0000BIN)03HEX= fourth byte bit 0 and bit 1 corrected (0000 0011BIN)
