    Product overview Product overview Intended use The CX20x0 device series is a modular control system designed for DIN rail installation. The system is scalable, so that the required modules can be assembled and installed in the control cabinet or terminal box as required.

  • Page 9: Fieldbus Module Cx2500-M310/B310

    The fieldbus module CX2500-M310 is a PROFIBUS master and enables a segment-like construction of control structures in large plants and machines. Further Beckhoff fieldbus components such as Bus Couplers, Bus Terminal Controllers, drive components, etc. can be used with an Embedded PC for configuring control structures.
  • Page 10 PROFIBUS DP offers short system response times: at a transmission rate of 12 Mbaud, less than 2 ms are required to transmit 512 bits each of input and output data to 32 devices. All Beckhoff PROFIBUS devices feature a high-performance protocol implementation and are certified by the PROFIBUS user organization (PNO).

    A maximum of 126 devices (master or slaves) can be connected to one bus. A station address between 0 and 99 can be chosen for the Beckhoff PROFIBUS slaves from the IPxxxx-B310, IL230x- B310 and IL230x-C310 series. The specifications for the system configuration contain the number of stations, the assignment of the station addresses to the I/O addresses, data consistency of the I/O data, the format of the diagnostics messages and the bus parameters being used. Every PROFIBUS...

If the parameter is False then the DPM1 remains in the operating state even after a fault, and the user can himself specify the system's reaction.

  • Page 14: Communication Protocols And Services

    Product overview Communication protocols and services In PROFIBUS DP systems a master (PLC, PC, etc.) usually communicates with many slaves (I/Os, drives, etc.); only the master actively accesses the bus (by sending unsolicited telegrams), while a DP slave only sends telegrams when requested by the master. PROFIBUS DP •...
  • Page 15 Product overview • Class 1 and Class 2 DP Masters The Class 1 master refers to the controller that carries out cyclic I/O data exchange with the slaves, while a Class 2 master is a B&B device that generally only has read access to the slaves' I/O data. PROFIBUS DPV1 PROFIBUS DPV1 refers primarily to the acyclic read and write telegrams, with which data sets in the slave are acyclically accessed.

    Mounting and wiring Installing the bar clips Installing the bar clips Usually, the connection between the modules is strong enough. However, the basic CPU module and the fieldbus modules may be subjected to shocks, vibrations or other impacts. The modules can be securely connected to one another with the aid of bar clips.

    Mounting and wiring Installation on the mounting rail Installation position and minimum distances The modules or devices may overheat, if the installation position is incorrect or the minimum distances are not adhered to. The devices may only be operated at ambient temperatures up to 60 °C. Ensure adequate ventilation.
  • Page 23 Mounting and wiring Installation on the mounting rail Avoid damage Do not use force or excessive pressure when installing the devices on the mounting rail. The CX20x0 can easily be installed on the mounting rail. The housing is designed such that it can be pushed against the mounting rail and engaged on it.

    Mounting and wiring Profibus Connection Nine-pin D sub Pin 6 transfers 5 V pin 5 transfers GND for the active termination resistor. These must never be used for other functions, as this can lead to destruction of the device. Pins 3 and 8 transfer the PROFIBUS signals. These must never be swapped over, as this will prevent communication.

  • Page 26: Cabling

    Pre-assembled cable from BECKHOFF Installation is made a great deal more straightforward if pre-assembled cables from BECKHOFF are used! Wiring errors are avoided, and commissioning is more rapidly completed. The BECKHOFF range includes fieldbus cables, power supply cables, sensor cables and accessories such as terminating resistors and T-pieces.
  • Page 27 Mounting and wiring The following diagram shows the cabling between two stations, as well as the D sub connection assignment: Termination resistors In systems with more than two stations all devices are wired in parallel. It is essential that the bus cables are terminated with resistors at the conductor ends in order to avoid reflections and associated transmission problems.
  • Page 28 Mounting and wiring If these measurements are successful, the cable is okay. If, in spite of this, bus malfunctions still occur, this is usually a result of EMC interference.

  • Page 43: Synchronizing Profibus

    Parameterization and commissioning Synchronizing Profibus In TwinCAT Run mode the Profibus master is always synchronized with the highest priority task, with which variables are linked. Once the mapping was created, the cycle time of the corresponding task is displayed under Cycle Time on the CCAT PBM tab of the master. It is possible to set for the task whether the "I/O at task begin"...
  • Page 44 Parameterization and commissioning This case would still not be a problem, because the DP cycle was completed within the available time. If the setting I/O at task begin is not activated, the sequence is somewhat more critical. The next example shows the effects.
  • Page 45 Parameterization and commissioning Comparison of I/O at task start and I/O not at task start The advantage of the I/O at task begin setting is that the task and the DP cycle do not have to share the available bandwidth. The DP cycle starts very constant (the jitter corresponds to the TwinCAT jitter). If the setting I/O at task begin is not activated, it can easily happen that a DP cycle is omitted, and the temporal constancy of the DP cycle additionally depends on the jitter of the task processing.

    Error handling and diagnostics Error Reactions Failure of a slave If a slave does not respond or the response is faulty, the master repeats the telegram several times, up to the Max Retry limit (see: Bus Parameters (DP) [} 34]). If a faulty telegram is received, the master repeats the telegram immediately.
