IEC 61158-5-19:2010(E) specifies the structure and services of the type 19 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 second edition cancels and replaces the first edition published in 2007 and constitutes a technical revision. The main change with respect to the previous edition are: - increasing the number of supported devices (511 instead of 254); - introducing a communication version identification; - adding a mechanism for remote address allocation; - introducing enhanced parameter addressing (32 bit instead of 16 bit); - restructuring control and status word; - improving the redundancy and hotplug features; - improving the error handling; - adding a multiplexing protocol (SMP: Type 19 Messaging Protocol).
