Overview
Machinery cybersecurity under Regulation (EU) 2023/1230 is a safety topic. The core legal issue is protection against corruption: connected devices, software, data, configuration, and intervention evidence must be handled so that corruption does not lead to a hazardous situation.
Topic architecture
The topic starts with the product placed on the EU market or put into service, then moves to the Annex III requirement, the safety risk assessment, the draft machinery cybersecurity standard, and the supporting industrial-control evidence. Each page in this cluster answers a different reader task.
Products in scope
Regulation (EU) 2023/1230 applies to machinery, listed related products, and partly completed machinery. Software can also be a safety component when the legal definition is met.
Protection against corruption
Annex III section 1.1.9 is the cybersecurity anchor. It is tied to hazardous situations, critical software and data, and evidence of intervention.
Risk assessment
Cybersecurity belongs in the machinery risk assessment when a corruption path can compromise a protective measure or create a hazardous situation.
Software and change
Software versions, configuration, updates, intervention evidence, and substantial modification need their own lifecycle analysis.
prEN 50742
prEN 50742 is a draft source for machinery-specific protection against corruption. Its status must stay separate from a final harmonised standard.
Robotics
ISO 10218-1:2025 adds cybersecurity only to the extent that it applies to industrial robot safety.
IEC 62443
IEC 62443 can support secure development, system, and component evidence, but it does not replace the Machinery Regulation.
Evidence chain
The useful record links the product boundary, safety functions, interfaces, software/configuration, protection measures, and user information.
Reading path
Read the pages in this order when the product is a connected machine, robot, machine control system, safety component, or partly completed machinery with safety-relevant software or data.
Source status
The cluster keeps binding law, draft standards, final standards, and industrial-control guidance separate. This matters because only the legal text creates the essential health and safety requirement, and only an OJ-cited harmonised standard can create presumption of conformity for the requirements and scope it covers.
Regulation (EU) 2023/1230 was published in the Official Journal and contains Annex III section 1.1.9 on protection against corruption.
The Regulation applies from this date, subject to earlier dates for specified administrative and transitional provisions.
CEN-CENELEC says CLC/TC 44X will continue work on EN 50742 for machinery protection against corruption. The local prEN 50742 source is still a draft.
ISO 10218-1:2025 is a final robot safety standard for industrial robots. It is not a general cybersecurity standard.
Safety boundary
A cybersecurity weakness is a Machinery Regulation issue when it can affect the machinery or related product as a safe product. A service port that can change a safety limit, a robot configuration that can alter a safeguarded space, or a firmware update that can change safe stopping behaviour belongs in the safety analysis. A business-system compromise on the same factory network does not become Annex III section 1.1.9 evidence unless the path can affect machinery safety.
