    Examples 6.17. Module programming Task (example): Sets of 12 pieces each are to be transported on a conveyor belt. The drive of the belt is operated by start and stop keys. The belt is stopped after every twelfth piece. Before leaving the belt, each piece triggers an impulse via an initiator which is used for counting.

  • Page 165: Reactions To Failures

    Reactions to failures D. Reactions to failures The KUAX 680C monitors itself. Any occurring errors or fail- ures are reported and lead to reactions in the control according to their dangerousness. The errors and failures are numbered from 1 through max. 255.
  • Page 166 Appendix Legend for the failures overview LED "failure" The red light emitting diode is located on the left side of the de- vice. It flashes in a rhythm that indicates the failure number: Flash rhythm etc. The counting impulses follow each other in a short sequence (250/250 ms).

  • Page 171: Checksum In The User Program (Failure #8

    Reactions to failures D.4. Checksum in the user program (failure #8) During program generation, a checksum (CS) is generated over the entire user program memory according to a certain algo- rithm. Cause When starting the controller, the monitor re-calculates the checksum and compares it to the stored value.

  • Page 172: Hierarchy Error (Failure #9

    Appendix D.5. Hierarchy error (failure #9) Program calls and other module calls must not exceed certain hierarchy limits (see chapter "4.7. Module programming"). During programming, the controller reports a hierarchy error when it receives a program. At this stage, this is only a warning that there could be an error.

  • Page 174: Software (Monitor Program

    Appendix E.2. Software (monitor program) The monitor program of the KUAX 680C is stored in the Flash- EPROM. This has the great advantage that new versions can be transferred into the controller easily by using a PC and the re- quired program.
