BOX ICT. B BOX X1149: Boundary Scan Solution. VIPER: How to take advantage of modular test systems.
Like its predecessor PROFIBUS, PROFINET is a diagnostic-rich protocol allowing your support team to quickly identify the source of device-related problems. This however is of limited use if the underlying performance of your network is poor. PROFINET networks are often seen as the plug and play solution for industrial networks, giving you the impression that successful completion of your application-specific testing is a guarantee that your network is working efficiently and without errors. This is fundamentally wrong and needs to be considered at the design stage as well as the acceptance stage of a project. This presentation will discuss the issues, how to address them and give typical examples of the equipment required.
PROFINET is a member of a family providing industrial communications over Ethernet.
PROFINET is:
completely standard Ethernet (IEEE802.3).
High speed, operating at 100Mbit/s or faster over copper or fibre-optic cables,
makes use of existing IT standards. But, is “real-time” and deterministic,
PROFINET is very well thought out to incorporate all the requirements of automation and control systems.
PROFINET is totally compatible with PROFIBUS but is NOT PROFIBUS over Ethernet.
PROFINET wiring is quite different to PROFIBUS
PROFIBUS:
Uses multi-drop segments with many devices on one cable. Segments are separated by repeaters.
Two-core screened twisted pair cable.
Termination is in the hands of the user – many problems arise because of this.
PROFINET :
Multi-drop connection is not used; all cables connect just two devices together. Switches are used for branching to devices.
Four-core screened twisted pair cable.
Termination is provided within every Ethernet device; no longer in the hands of the user – should eliminate termination problems.
PROFINET – Commissioning Guideline
This is one of several free-to-download guidelines documents from PNO (PROFIBUS and PROFINET User Organisation).
It provides guidance on how to verify the installation aspects of the network as well as how to commission the live system.
These tests are additional to the application-specific, System Acceptance Testing that would usually be performed.
Failure to follow these guidelines puts you at risk of having your application tests pass without a detailed knowledge of the underlying performance of your network

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Assigning the I/O
Foundation fieldbus devices are recognized by three
mechanisms: a traditional node address for communication, a
human readable device tag corresponding to the project P&I
diagram, and a unique identifier allowing the system to
automatically resolve any tag or address conflicts.
The system automatically assigns the address to all devices,
avoiding human errors such as address duplication associated
with manually managed protocols, and saving time.
Therefore technicians work based on tag and need not be
concerned with address.
Thanks to the unique identifier, multiple devices can be
connected and commissioned at the same time.
It is plug-'n'-play.
