ISO 13849-1 PL eIEC 61508 SIL 3
- R08SFCPU-SET80K*1
- R16SFCPU-SET160K*1
- R32SFCPU-SET320K*1
- R120SFCPU-SET1200K*1
*1.The program capacity of the safety control is 40K steps.
Interface
Safety and general control in one CPU module
- One system
- Space-saving
- Cost reduction
- Using the safety CPU module on CC-Link IE TSN or CC-Link IE Field Network can execute both general and safety programs, enabling easy integration into one control system
- Installation of separate programmable controllers and networks is unnecessary, saving on space and costs
General and safety programs in the common engineering platform
- Integrated program
- In engineering software GX Works3, general programs and safety programs are included in the same project folder
- The need to manage multiple project folders is eliminated
