  • Page 17: Exchanging Data Using The Simatic Fb's

    In the case of the data transfer protocol “unstructured ASCII driver” in combina- tion with the RS485 serial interface, the SPI 3 sends the telegram which is re- ceived from the DP master for the serial partner back to the DP master again.

    The control data or user data to be exchanged is copied to a special PLC memory area – the data block (DB) – from where the PLC writes the data to the SPI 3 through the DP master. The data block consists of several data words, whereby data words 0 to 5 (DW0 to DW5) are reserved for internal use.

Abbreviation for binary digit, the smallest unit in the binary sys- tem; it can have the value 0 or 1. Cable with two defined ends which is used for exchanging data between the connected bus stations.
  • Page 33 Data channel A logical channel for exchanging data with the SPI 3. The size of the data channel (i.e. I/O area) is dependent on the SPI 3 configuration. If a telegram is larger than the data channel, it needs to be fragmented.
  • Page 34 Mirror The input byte 0 of a data channel is called the mirror. The SPI 3 mirrors (returns a copy of) the stamp (q.v.) to confirm the oper- ation or when user data is being processed. Mirror = 0 indicates that the DP slave is ready for data exchange.
