  • Page 12: Mounting Of The Modules

    1.5. Mounting of the modules In order to expose the controller modules to the minimum mechanical stress they should preferably mounted horizontally or vertically on the mounting panel. The module must be fixed with four screws to DIN 7500 or DIN 7984 (M5 x If possible, the modules should be mounted in such a way that the cable entry of the plug points downwards.
  • Page 13 If an output terminal receives current externally, e.g. for bidirectional inputs and outputs, the output rail must not be floating (i.e. open-circuit) Reason The supply voltage is fed back to the output rail via the integrated protective diode in the output. If a second output connected to the same potential is switched, the load of this output is fed through the transistor of the first output thus causing the first output to overload and fail.

  • Page 15: The Monitoring Function

    The monitoring function The safe operation of the controller outputs is ensured by the monitoring function. 2.1. Hardware setup The relay is triggered on two channels via the µcontroller. For this purpose the negative channel is triggered by means of an AND link of the watchdog signal (internal µcontroller monitoring) and the RELAY bit with a semiconductor switch.
  • Page 16: Function Of The Monitoring Concept

    2.2. Function of the monitoring concept While the program is running the monitoring relay is under the complete control of the software user. A parallel contact from the safety circuit for example can be evaluated as an input and the monitoring relay can be switched off. For further safety the appropriate national regulations must be applied.

    Unit I/O configuration The unit I/O configurations described in the annex are available as standard units (ex stock). They cover the required specifications for most of the applications. Depending customer’s requirements series applications it is possible to realise other configurations, e.g. regarding the arrangement of inputs and outputs and the design of the analog channels.
  • Page 18: Outputs With Diagnostic Functions

    This function is based on the condition that in the controllers high-side outputs are combined with low-side inputs or low-side outputs are combined with high-side inputs so that no conflicts can occur, i.e. short circuit via the switched output transistor and closed switch at the input.
  • Page 19: Fast Inputs

    The block circuit diagram shows: • Short-circuit detection (overload) is possible via the input channel. When the output is switched the LOW (logic 0) can be read in. The output transistor automatically switches off in the case of a short circuit/overload. For safety reasons it does not switch on again automatically.

  • Page 32 If a participant immediately detects an error it made (it is responsible for the error), this participant is more severely "punished" for the error than the other bus participants. To do so, the counter is incremented by a higher amount. If the count exceeds a certain value, it can be assumed that this participant is faulty.
  • Page 33: The Physical Can Link

    The standard ISO 11898 assumes a line-structured set-up of the CAN network. In addition, the line must be fitted with a terminating resistor of 120 Ω Ω Ω Ω at its two ends. In principle, ifm electronic's devices fitted with a CAN interface have no terminating resistors.
  • Page 34 Bus level The CAN bus is in the inactive (recessive) state if the output transistor pairs are switched off in all bus participants. If at least one transistor pair is switched on, a bit is sent to the bus which then becomes active (dominant).
