    PR electronics fieldbus transmitters are delivered with a CD that contains the files needed to configure the transmitters from a fieldbus host. These files can also be downloaded from our homepage www.prelectronics.com.

  • Page 5: The Resource Block, Fieldbus Foundation

    The resource block is used to define a hardware specific characteristics of the function block applications. It provides PR’s manufacturer’s name, device name, DD and block status and hard- ware details. It also indicates how much resource (memory and CPU) is available and controls the overall device.

  • Page 6: Features / Feature_Sel Parameters

    1.7 FEATURES / FEATURE_SEL parameters The bit strings FEATURES and FEATURE_SEL determine optional behaviour of the resource. The first defines the available features, and is read only. The second is used to turn on an available feature by configuration. If a bit is set in FEATURE_SEL that is not set in FEATURES, the result will be a block alarm for a configuration error.

    3.0 Analogue Input Blocks PR5350 has 2 Analogue Input Blocks to be configured individually. The constrcution of the Blocks is in line with the standards from FOUNDATION Fieldbus and Profibus Nutzerorgan- isation respectively, and producer specific parameters have not been added. However, the Analogue Input Blocks for Fieldbus Foundation and Profibus are dissimilar due to the para-me- ter differences.

    4.0 PID Control Block, Fieldbus Foundation 4.1 Introduction: PR5350 is fitted with a PID Control Block which can only be used in Fieldbus Foundation in- stallations. The PID Block is constructed according to standard specifications outlined in Fieldbus Foundation and producer specific parameters have not been added. Please notice that the PID function is not specified in the Profibus Nutzerorganisation and thus cannot be used in Profibus installations.

    This status is a copy of IN’s status unless IN is good and there is a PV or block alarm. The full cascade SP sub-function is used, with rate and absolute limits. There are additional control options which will cause the SP value to track the PV value when the block is in an ac- tual mode of IMan, LO, Man or ROut.
