Pluto All-Master
Pluto is an ”All-Master” safety PLC concept, that simplifies the
design of safety systems and achieves the highest safety level PL e
according to EN ISO 13849-1 and SIL 3 according to EN 62061
andEN 61508. The key difference betweenPluto 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 'Mas-
ter' 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 communicatewith other bus systems and thereby form
part of a larger network. Gateway units are available for several
different bus systems, such as Profibus, CanOpen, DeviceNet,
Profinet, Ethernet/IP and Modbus TCP. With a Pluto AS-i, both
safety slaves and standard slaves can be handled.
Pluto offers an economic solution for both single machines and
for major machine systems.
