  • Page 17: Hart Function

    HART function Definition "HART" stands for "Highway Addressable Remote Transducer". The HART protocol is a standardized communication protocol for communication with the suitable field devices over a bus system. HART is a registered trademark of the HART Communication Foundation (HCF), which owns all the rights to the HART protocol.

  • Page 18: How Hart Works

    HART function 4.1 How HART works How HART works Introduction The HART protocol describes the physical form of the transfer: transfer procedures, message structure, data formats and commands. HART signal The figure below shows the analog signal with the modulated HART signal (FSK method), which consists of sine waves of 1200 Hz and 2200 Hz and has a mean value of 0.
  • Page 19 HART function 4.1 How HART works If a HART field device with a different short frame address is connected or a connected field device is reconfigured to a short frame address other than 0 during operation, the module starts a scan of all possible short frame addresses at the next re-establishment of HART communication (command 0 with short frame addresses 1...63).

  • Page 23 HART function 4.2 Use of HART Error management The two HART status bytes (HART device status) that are transferred with each field device response contain error statements about HART communication, HART command and device status. These statements are evaluated by the analog module and provided in the system via S7 diagnostics messages.

  • Page 24: Hart Communication Interface

    HART function 4.3 HART communication interface HART communication interface Data records The HART commands are sent over data records to the connected field device as "external HART jobs" from the client (e.g. PDM or the STEP 7 user program). The response of the field device is made available again in the system via data records.
  • Page 25 HART function 4.3 HART communication interface Each request is stored on a channel-specific basis, and the corresponding request data record is disabled. Another writing of the same request data record is thus not possible and is acknowledged with BUSY. The disable of the request data record is reset after the termination or completion of the requested HART command.
