Unsafe operating states resulting from software manipulation
Software manipulations, e.g. viruses, Trojans, or worms, can cause unsafe operating states in
your system that may lead to death, serious injury, and property damage.
• Keep the software up to date.
• Incorporate the automation and drive components into a holistic, state-of-the-art industrial
• Make sure that you include all installed products into the holistic industrial security concept.
• Protect files stored on exchangeable storage media from malicious software by with suitable
• On completion of commissioning, check all security-related settings.

Residual risks of power drive systems
When assessing the machine- or system-related risk in accordance with the respective local
regulations (e.g., EC Machinery Directive), the machine manufacturer or system installer must
take into account the following residual risks emanating from the control and drive components
of a drive system:
1. Unintentional movements of driven machine or system components during commissioning,
operation, maintenance, and repairs caused by, for example,
– Hardware and/or software errors in the sensors, control system, actuators, and cables and
– Response times of the control system and of the drive
– Operation and/or environmental conditions outside the specification
– Condensation/conductive contamination
– Parameterization, programming, cabling, and installation errors
– Use of wireless devices/mobile phones in the immediate vicinity of electronic components
– External influences/damage
– X-ray, ionizing radiation and cosmic radiation
2. Unusually high temperatures, including open flames, as well as emissions of light, noise,
particles, gases, etc., can occur inside and outside the components under fault conditions
caused by, for example:
– Component failure
– Software errors
– Operation and/or environmental conditions outside the specification
– External influences/damage
