Safety PLC
Cat. 4/PL, e/SIL 3, EN 954-1 JOKAB SAFETY



Pluto is an "All-Master" safety PLC concept, that simplifies the design of safety systems and achieves the highest safety level (category 4) according to EN 954-1/EN ISO 13849-1 and SIL 3 according to IEC/EN 61508. The key difference between Pluto and conventional safety PLC´s is that there is no "Master-Slave" relationship between the control units connected to the safety bus. Each Pluto is a 'Master' unit and can see the other Plutos' inputs and outputs, and can thereby make decisions about its own safety environment. This concept enables simple communication, programming and changes to the safety system. With the use of a 'Gateway' device, a Pluto can communicate with other bus systems and thereby form part of a larger network.
