Amendment 1 - Industrial communication networks - Profiles - Part 3-18: Functional safety fieldbuses - Additional specifications for CPF 18

Applies to radiotherapy simulators:[
]- that use diagnostic X-ray equipment to simulate physically a therapeutic radiation beam, so that the treatment volume to be subjected to irradiation during radiotherapy can be localized, and the position and size of the radiotherapy radiation field can be confirmed;[
]- intended exclusively for radiotherapy simulation as a prelude to intended radiotherapy, and not for any other purpose such as general diagnostic examinations.[
]Establishes requirements to ensure the ionizing radiation safety and enhanced mechanical and electrical safety of radiotherapy simulators; it identifies geometrical parameters that are critical for the accurate simulation of a radiotherapy treatment.[
]Cancels and replaces the first edition published in 1993 and its amendment 1 (1996).

Amendement 1 - Réseaux de communication industriels - Profils - Partie 3-18: Bus de terrain de sécurité fonctionnelle - Spécifications supplémentaires pour le CPF 18

S'applique aux simulateurs de radioth�rapie:[
]- qui utilisent un �quipement � rayonnement X de diagnostic pour simuler la g�om�trie d'un faisceau de rayonnement afin que le volume trait� soumis � l'irradiation pendant la radioth�rapie puisse �tre localis� et que la position et les dimensions du champ de rayonnement de radioth�rapie puissent �tre confirm�es;[
]- utilis�s exclusivement pour une simulation de radioth�rapie pr�liminaire � un traitement de radioth�rapie d�termin�, et non pour d'autres utilisations telles que les examens de diagnostic g�n�ral.[
]Etablit des prescriptions qui ont pour but d'assurer la protection contre le rayonnement ionisant et de renforcer les niveaux de s�curit� m�canique et �lectrique des simulateurs de radioth�rapie. Identifie les param�tres g�om�triques qui sont essentiels pour la simulation pr�cise d'un traitement par radioth�rapie.[
]Annule et remplace la premi�re �dition parue en 1993 et son amendement 1 (1996).

Add, in this subclause, at the end of the list, the following new items:

• For devices using protocol version 2 (see 7.1.3.4) it is required to add 10 to the PFH

of the device hardware to account for the communication channel.

NOTE In this way, the user of the device will not have to account for the number of logical connections

within a safety function.
• The use of error correction mechanisms in the black channel is permitted.
