IEC PAS 61158-5-22:2009
Industrial communication networks - Fieldbus specifications - Part 5-22: Application layer service definition - Type SNpTYPE elements
IEC/PAS 61158-5-22:2009(E) provides user programs with a means to access the fieldbus communication environment. In this respect, the FAL can be viewed as a "window between corresponding application programs." It provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type SNpTYPE fieldbus. It contains an additional profile - SNpTYPE - which may be integrated into a future new edition of the IEC 61158-5 series.

IEC 61158-5-22:2010 specifies the structure and services of the type 22 IEC fieldbus Application Layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498) and the OSI Application Layer Structure (ISO/IEC 9545). This standard cancels and replaces IEC/PAS 61158-5-22 published in 2009. This bilingual version published in 2012-01 corresponds to the English version published in 2010-08.
