2 The Safety Simplifier System overview and features
The Safety Simplifier system is a PLC-system, designed to be a part of an Equipment Under Control
(EUC) requiring a Safety Integrated Level (SIL) up to SIL 3 according to IEC 61508 and Ple, cat 4
according to 13849-1. The Safety Simplifier is a Safety PLC intended to solve logic for one or several
safety functions in an EUC.
The safety connections to safety devices and machines are intended to be done via the I/O: s of
Safety Simplifier. The Safety Simplifier/s can also communicate with each other via radio and /or CAN-
bus cable for the safety logic.
The configuration software Simplifier Manager is used for:
- Programming and compiling logic that can be run on Safety Simplifier
systems
- Configuring Safety Simplifier devices as systems
- Monitoring and debugging Safety Simplifier systems
- Generating documentation about Safety Simplifier system
Configuration of Safety Simplifier devices is performed either via USB using the micro USB connector
inside the Safety Simplifier, or wirelessly using Simplifier Monitor.

combination of CAN and radio to communicate.
