However it is an inescapable fact that as automation systems become more intelligent then so must the safety system.
What is required for safer functionality increasingly depends on what the machine is doing or what mode it is in. This means that "safety" has, in some way, to communicate with the "normal" control system. That means that we need to reconsider how we achieve the independence and integrity of the safety system. One of the most significant manifestations of this is a new generation of standards commonly referred to as Functional Safety Standards.
In addition to this, there is a new Machinery Directive in the EU that looks to keep the legislative landscape relevant to the contemporary industrial environment. For anyone supplying machines or using them it is important to keep informed of the relevant standards and regulatory requirements.
This publication is intended to assist in that task especially with regard to control system aspects.
Safety of machinery. Safety-related parts of control systems. General principles for design
It is not a substitute for a detailed study of the specific provisions detailed in the standards and legislation. It is intended to give an overview and hopefully it will help to give some clarity on what is required. At the end of December EN will be withdrawn [its counterpart ISO has already been withdrawn] The main implication of this is the fact that after that date this standard can no longer be used to show conformity with the Machinery Directive.
A new standard to replace EN has already been published.
Either of these standards can be used to show conformity with the Machinery Directive. In this publication we will consider the relationship between the two standards where relevant. It has been specifically drafted to provide a transition path for system designers who have been using Categories and therefore it is likely to become the most commonly used standard for machine safety systems. It can be used either for a complete system or for a subsystem.
The outputs of the old standard were Categories [B, 1, 2, 3 or 4].
The outputs of the new standard are Performance Levels [PL a, b, c, d or e]. The Category concept is retained but there are additional requirements to be satisfied before a PL can be claimed for a system.
Essentially this captures what we have become used to as the Categories. This effectively represents the amount of fault monitoring in the system.
It is clear at this stage that there are new things to learn but the detail will make more sense once we have understood what it is trying to achieve and why. First of all why do we need the new standard?
