Requirements for use

This article lists the requirements for Neuron Power Engineer when developing safety-relevant applications:

Requirements for the development process

Warning 1

A defined development process is required for the development and the commissioning of safety-relevant applications.
The development process must deal with the requirements of the appropriate underlying standard, in particular with the required validation and verification measures.

Properly trained personnel

Warning 2

Neuron Power Engineer must be used by properly trained personnel only.

Properly trained personnel are qualified persons with all the following characteristics and skills:

  • persons planning, developing, assembling and/or commissioning safety-relevant applications

  • persons that given their knowledge, experience, qualifications and/or training are authorized to use Neuron Power Engineer (as described in the documentation "Safety instructions on working with the IDE" and are able to detect and prevent possible risks

  • persons familiar with the relevant safety concepts for automation engineering

  • persons familiar with the underlying standards and regulations

  • persons familiar with the instructions of the manufacturer manual for the safety system

  • persons familiar with the instructions of this document – Hence, sufficient language skills are required to understand all instructions given in this document.

Warning 3

Organisational measures must be taken to ensure that only a qualified person can access the safety-relevant applications and the safety →PLC.

Those measures can include:

  • keeping authentication information secure
    That means: Do not write them down or share them with unauthorized persons.

  • when leaving the working place

    • exiting Neuron Power Engineer

    • locking the computer screen

Warning 4

Persons using Neuron Power Engineer must have appropriate knowledge, experience and qualifications relevant for the tasks they are performing. These tasks are in particular: creating/editing the safety-relevant application, verifying and validating the safety-relevant application, releasing the safety-relevant application for operation.

The person performing the task(s) must be a qualified person that has appropriate knowledge, experience and qualifications with the following aspects:

  • safety engineering

  • safety concepts in automation engineering

  • accident detection and prevention

  • extent of the consequences in the event of a failure

  • possibly existing company guidelines

  • the references and standards

  • the manual of the safety system

  • the safety manuals or the appropriate documentation on performing the safety-relevant tasks
    This is: this documentation "Safety instructions on working with the IDE" (in particular, its specific instructions) as well as the documentation "logi.µSRTS safety manual" (and its specific instructions)

When one person is performing different tasks in accordance to the references/standards or company guidelines, the degree of independence must be observed.

Warning 5

Neuron Power Engineer does only provide basic authentication/authorization support. The operator of the safety PLC must ensure, that the safety system as well as the working places where the safety-relevant applications are created and/or modified, are protected against unauthorized access.
Those measures can include restricting the access to the PLC (for example private network, VPN).
