Vendor independence and openness are guaranteed by the PROFIBUS standard EN 50170. With PROFIBUS, devices of different manufacturers can commu- nicate without special interface adjustments.The PROFIBUS family consists Standard EN50170 of three compatible versions:...

    They do not have bus access rights and they can only acknowledge received messages or send messages to the master when requested to do so. Slaves are also called pas- sive stations. The CJ1W-PRT21 is a PROFIBUS-DP slave device.

  • Page 24: Profibus-Dp Characteristics

    PROFIBUS-DP characteristics Section 1-4 PROFIBUS-DP characteristics 1-4-1 Bus Access Protocol Layer 2 The bus access protocol is implemented by layer 2. This protocol also includes data security and the handling of the transmission protocols and messages. Medium Access Control The Medium Access Control (MAC) specifies the procedures which determine when a station is permitted to transmit data.

  • Page 25: Data Throughput

    PROFIBUS-DP characteristics Section 1-4 Multi-peer communication In addition to logical peer-to-peer data transmission, PROFIBUS-DP provides multi-peer communication (broadcast and multicast). Broadcast communication: an active station sends an unacknowledged message to all other stations (masters and slaves). Multicast communication: an active station sends an unacknowledged message to a predetermined group of stations (masters and slaves).

    PROFIBUS-DP characteristics Section 1-4 1-4-4 Protection mechanisms Time monitoring PROFIBUS-DP provides effective protection functions against parameterisa- tion errors or failure of the transmission equipment. Time monitoring is pro- vided at the DP master and at the DP slaves. The monitoring interval is spec- ified during the configuration.

    Section 4-1 Input and Output Data The CJ1W-PRT21 forms a link between two bus systems: the host PLC’s I/O bus on one side, and PROFIBUS-DP on the other. The Unit can be consid- ered as a slave to both systems: the I/O bus communication is controlled by the CPU Unit of the host PLC, the PROFIBUS-DP communication is control- led by a PROFIBUS-DP master.

    Input + outputs must be 180 words or less. I/O Data Format The CJ1W-PRT21 allows the user to select between two methods to map the word-oriented PLC data to the essentially byte-oriented PROFIBUS-DP mes- sages. The default method is Motorola format (Big-Endian), which allows easy data exchange with other OMRON PROFIBUS-DP devices.

  • Page 52: Data Mapping

    Data Mapping Section 4-4 Data Mapping The mapping of PROFIBUS I/O data to the host PLC is controlled by the Set_Prm (set parameter) and Chk_Cfg (Check configuration) telegrams sent by the PROFIBUS Master. At startup of the PROFIBUS communication the following commands are sent.

  • Page 53: Control And Status Area

    CIO 2940-CIO 2949 4-5-2 Control bits The PROFIBUS-DP communication status of CJ1W-PRT21 can be controlled through the first CIO word (CIO n) allocated via the Machine No. setting (n = 2000 + 10*Mach.No.). The communication status set by these bits is retained until the Unit is restarted (Power-on or reset).

  • Page 54: Status Flags

    Section 4-5 4-5-3 Status Flags The CJ1W-PRT21 indicates its status in the second CIO word (CIO n+1) allo- cated via the Machine No. setting.
