Safety code is not the place to cut corners. The S7-1500 F-CPU lets you run standard control and safety logic in one controller, which simplifies wiring and diagnostics. But it needs programming with care.

Bubble Automation programs S7-1500 failsafe systems using Siemens Safety Integrated. We implement safety functions such as emergency stops, guard interlocks and safe drive functions in line with your risk assessment and safety design. Safety logic is kept clearly separated, well documented and verifiable.

Using the F-CPU alongside safe I/O and SINAMICS drives over PROFINET can reduce hardwired safety relays and make fault finding much easier. Operators get clear messages about what has tripped and why, rather than a dead machine and a mystery.

We test safety functions thoroughly during commissioning and provide the documentation you need for your records. If you are upgrading an older machine, we can help you take the opportunity to modernise the safety system at

Bubble Automation is based in Droxford, Hampshire and works across the UK. Get in touch to talk through your system with an engineer who knows Siemens inside out.
