4. Commissioning 4.2 Preparing the CPX terminal for commissioning CPX terminals can be connected to various fieldbuses. Connection is made via the CPX bus node that is adapted to suit the relevant fieldbus. The reaction of the CPX terminal can be adapted to various requirements. You can carry out important settings as follows: With the DIL switch directly on the CPX bus node (see section 3.1.2). By parametrisation (see section 4.2.1). The DIL switch and the parameters are preset at the factory.
4. Commissioning Note Do not connect the cables for the fieldbus when preparing for commissioning. In this way, you can avoid: Addressing errors that may occur due to the modification of the address range during operation with various fieldbus systems. Proceed with preparation as follows: 1. Check the pneumatic tubing of the valve terminals with the aid of the manual override (see manual for specific pneumatics). 2. Check the entire electric wiring of the CPX terminal. 3.
4. Commissioning 4.2.1 Parameter types The parameters are preset at the factory. These pre−settings can be used for a large number of applications. With the aid of parametrising, the characteristics of the CPX terminal or the characteristics of the individual modules and I/O chan nels can be adapted to each particular application. The possibilities available depend on the fieldbus protocol used. Information about this can be found in the manual for your CPX bus node.
4. Commissioning System parameters Brief description Diagnostic monitoring with: Short circuit/overload Undervoltage of outputs Undervoltage of valve supply The monitoring of short circuit and overload for the complete CPX terminal can be switched on or off with this parameter.

C. General information on parametrisation C.1 Input debounce time Fundamentals Input debounce times are specified in order to eliminate in terfering changes of signal edge during switching procedures (bouncing of the input signal). For example, mechanical switches generate brief undesired signal edges during switch ing procedures. The signal states which are thereby produced can cause interference in the control sequence and should therefore frequently be suppressed.

C. General information on parametrisation C.2 Signal extension Fundamentals Signal extension times are specified when very short signals are to be taken into account in the control process. Short signals can occur, e.g. when an intermediate position is ex ceeded and evaluation is necessary in order to produce a time−optimised consequent process before an end position is reached.
C. General information on parametrisation Mode of operation Signal states accepted as logical input signals usually remain valid at least until the specified minimum signal duration has expired. Change of edge within the minimum signal duration are ignored (see Fig. C/2). Fixed debounce times remain ef fective. Case 1: Change of edge within the signal extension time The logical CPX signal is supplied when the signal extension time and, if applicable, the debounce time has expired.
C. General information on parametrisation Case 2: Change of edge after expiration of the signal extension time The logical CPX signal follows the input signal and is supplied after it. If a debounce time has been defined, the logical CPX signal is supplied when the debounce time has expired.
C. General information on parametrisation C.3 Influence of signal states You can influence the signal states of the CPX terminal through the following functions: Function Priority Brief description Signals able to be influenced Forcing 2) 1 Influences signal states independently of actual signal states (see also section C.3.1) I/O signals Fail safe 2 Determines signal states that become effective with fieldbus communication faults (see also section C.3.

The logical status of the input only changes internally and may be effec tive programme technically.
C. General information on parametrisation C.3.1 Force Fundamentals The function Force permits the manipulation of signal states independent of actual operating conditions. Force enables input and output signals to be overwritten, Input signals actually present or changes of status by program will be ig nored. The input signals actually present and the output sig nals generated by the user program only become valid again when the function Force is deactivated.
C. General information on parametrisation By means of a system parameter, Force is enabled globally for the CPX terminal or blocked. System parameters Settings Description Force mode Disabled (presetting) Force is blocked for the complete CPX terminal Enabled Force is enabled for the complete CPX terminal Tab. C/2: System parameter Force mode The signal status can be determined channel−orientated (out put/valve/input) for each module (see Tab. C/3).
C. General information on parametrisation Mode of operation Input information actually present will be replaced by the values entered in the Force table in the process image inputs. Information actually present in the process image outputs will be replaced by the values entered in the Force table and transmitted to the physical outputs.

C. General information on parametrisation C.3.2 Signal status in the event of a fault (Fail safe) Fundamentals With the aid of the so−called fail−safe parametrisation, the signal status which the outputs are to assume in the event of fieldbus communication faults, can be determined (fail−safe status). In this way, a defined machine/system status should be created in the event of fieldbus communication faults (e.g. failure of the higher−order PLC/IPC).

General information on parametrisation System parameters Settings Description Fail safe Reset outputs (presetting) Reset all outputs/valves Hold last state Retain current signal status for all outputs/ valves Assume Fault mode value Accept the signal status defined for the relevant channel Tab. C/4: System parameter Fail safe" If Accept fault mode value" is activated, the signal states defined by module parameter for the relevant channel will become effective (see Fig. C/8).

Fundamentals Idle mode parametrisation helps determine which signal status outputs/valves should take when changing into the Idle status. In this way a defined machine/system status should be created.

C. General information on parametrisation C.4 Diagnostic memory Fundamentals A diagnostic memory serves for protocolling fault states. If the time when faults occur and if fault sequences are regis tered, this will facilitate the search for the cause of the faults which are otherwise difficult to locate. If the causes are elim inated, faults can be avoided over long periods.
C.
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. A diagnostic entry consists of 10 bytes. The first five bytes contain information on the time point.
C. General information on parametrisation C.5 Monitoring errors Fundamentals Monitoring functions that run automatically can be activated and deactivated by parametrisation. The activation of monitoring functions helps to guarantee the functionality of the machine/system and to avoid unnecess ary idle periods. The deactivation of monitoring functions helps to avoid disturbing error messages, e.g.
