DESCRIPTION

BS EN 61158-2:2014


This standard BS EN 61158-2:2014 Industrial communication networks. Fieldbus specifications is classified in these ICS categories:
  • 35.100.20 Data link layer
  • 25.040.40 Industrial process measurement and control
  • 35.100.10 Physical layer
  • 35.240.50 IT applications in industry
IEC 61158-2:2014 specifies the requirements for fieldbus component parts. It also specifies the media and network configuration requirements necessary to ensure agreed levels of data integrity before data-link layer error checking and interoperability between devices at the physical layer. The fieldbus physical layer conforms to layer 1 of the OSI 7-layer model as defined by ISO 7498 with the exception that, for some types, frame delimiters are in the physical layer while for other types they are in the data-link layer. This sixth edition cancels and replaces the fifth edition published in 2010. It constitutes a technical revision. This edition includes the following changes:
- new Type 20 specification;
- new Type 24 specification;
- RS232 media specification for Type 4 removed.
