This will cause faulty operation. 1-1-2 PROFIBUS Communication Protocol  OSI Reference Model ISO-7498 In general, the PROFIBUS communication protocol is based on the Open System Interconnection (OSI) reference model in accordance with the international standard ISO-7498 (see the following illustration).

  • Page 42: Gsd File Technology

    1 Features and System Configuration  RS-485 Transmission Speed Transmission speeds between 9.6 kbps and 12 Mbps can be selected. One unique transmission speed must selected for all devices on the bus when the system is commissioned.  Cable Length The maximum cable length depends on the transmission speed.

  • Page 43: Device Types

    1 Features and System Configuration 1-1-4 Device Types PROFIBUS distinguishes between master devices and slave devices. The CJ1W-PRT21 is a PROFI- BUS slave device. Master Devices Master devices determine the data communication on the bus. A Master can send messages without an external request, as long as it holds the bus access right (the token).
  • Page 44 1 Features and System Configuration Token Passing DPM1 DPM2 DPM1 Active stations Master devices Polling PROFIBUS Passive stations Slave devices The three masters form a logical token ring. When an active device receives the token message, it can perform its master role for a certain period of time. During this time it can communicate with all assigned slave devices in a master- slave communication relationship, and a DPM2 master can take the initiative to communicate with DPM1 master devices in a master-master communication relation- ship.

  • Page 45: Data Throughput

    1 Features and System Configuration 1-1-6 Data Throughput  Transmission Time At 12 Mbps, PROFIBUS-DP requires only about 1 ms for the transmission of 512 bits of input data and 512 bits of output data distributed over 32 stations. The figure below shows the typical PROFI- BUS-DP transmission time depending on the number of stations and the transmission speed.

  • Page 46: Protection Mechanisms

    If the master’s Auto_Clear mode is enabled, the DPM1 exits the Operate state, switches the outputs of all assigned slaves to fail-safe status and changes to its Clear state (see 1-2 Configuring the CJ1W-PRT21 Slave Unit).  Monitoring at the Slave The slave uses the watchdog control to detect failures of the master or the transmission line.
  • Page 47 1 Features and System Configuration Auto_Clear When an error occurs during the data transfer phase of the DPM1, the ‘Auto_Clear’ configuration setting determines the subsequent actions. If this parameter is set to false, the DPM1 remains in the 'Operate' state. If set to true, the DPM1 switches the outputs of all assigned DP slaves to the fail- safe state and the network state changes to the 'Clear' state (see 3-6-2 Status Flags (*_SlvSta)).

  • Page 53: Performance

    1-3-2 Performance The task of the CJ1W-PRT21 is to exchange predetermined amounts of data between the host CPU system and a PROFIBUS-DP master unit. Its performance in terms of data transfer rate is therefore mainly governed by two factors external to the Unit: the PROFIBUS-DP cycle time and the host CPU’s cycle time.
  • Page 54 The time required to exchange I/O data between the CJ1W-PRT21 and its master will depend on the number of input and output words defined in the master’s configuration, the selected baud rate and on the performance of the master unit itself.
