PROFIBUS PA Field Device Protocol Software

Portable PROFIBUS PA Protocol Software for Field Devices

Softing’s PROFIBUS PA field device protocol software is optimized with respect to size, performance, and portability to support customer-specific hardware platforms. It is especially targeted to 16 Bit low-power microcontrollers and includes the complete range of protocol features for implementing conformant PROFIBUS PA field devices.

Overview

Fast adaptation to customer-specific hardware platforms

  • Complete solution, software-based
  • Especially designed for use in typical process automation field devices
  • Implementation optimized for usage in low-power microcontrollers typically found in hazardous areas
  • Suitable for many field device environments with a wide range in terms of microcontrollers, memory expansion and operating systems
  • Adaptable to device-specific requirements
  • Designed for use in customer-specific target platforms

Full range of functionality

  • Implementation according to the PROFIBUS specification
  • Including Function Blocks of the PROFIBUS PA profile from the PROFIBUS specification
  • Modular design for individual selection of the functionality supported in the respective field device

Support for general fieldbus ASICs

  • Implementation support not only for the PROFIBUS ASICs SPC4-2, but also for other fieldbus ASICs such as the UFC100-L1 from Softing
  • Possible parallel implementation of PROFIBUS PA and Foundation Fieldbus H1 field devices on identical hardware platform
  • Reduced implementation effort for second field device protocol when using the PROFIBUS PA and Foundation Fieldbus H1 field device protocol software from Softing in parallel
