    Use the Fail−safe parametrisation very carefully, in order to avoid damage. CPX parametrisation With CPX terminals, fail−safe parametrisation can be used for: Digital outputs Analogue outputs Valves By means of the system parameter fail−safe, you can globally determine the signal status which the outputs/valves are to assume in the event of fieldbus communication faults, e.g.

    With these filters the registering of certain system states can be suppressed, and both starting and stopping can be con trolled. The method of operation of the diagnostic memory filters is shown in Fig. C/10. C−20 Festo P.BE−CPX−SYS−EN en 0902e...

  • Page 220 C. General information on parametrisation Mode of operation With the CPX terminals the start and end of a fault can be protocolled in the internal diagnostic memory. The diagnostic memory contains up to 40 entries. In addition to information on localising the fault, the relevant time point is saved, measured from the moment the power supply is switched on.

    (e.g. short circuit, wire fracture, undervoltage, etc.). The different monitoring functions can be activated or deactivated globally by system parameters for the complete CPX terminal and by module parameters for a single CPX module or an individual channel. Activation of a monitoring function causes the following: C−23...
