Omron: Safety controller
Designed for applications such as automotive robotic work cells, larger flexible packaging machines, and material handling work cells with multiple access points, the NX series of safety controllers from Omron utilizes one network, one connection, and one software to provide integrated automation and safety from a single platform.
The NX series uses the same EtherCAT network in a mixed I/O backplane to promote design flexibility and minimize wiring costs. A single intuitive software programming environment reduces machine and safety design time, while an auto configuration restart function eliminates the need for tools or software to exchange I/O hardware.
In combination with the company’s new NX I/O system and Sysmac NJ Controllers, the safety controller series represents a step towards the complete integration of safety, logic, motion, and vision disciplines.
The open protocol Safety over EtherCAT (FSoE) defines a safety related communication layer for EtherCAT. The NX Safety Controller and the distributed Safety I/O can be freely placed in the EtherCAT network, and their integration in the Sysmac Studio software environment simplifies initial system design, setup, and maintenance of the application.
NX series safety controllers add ease and flexibility in programming the safety system with direct access, by the PLC, to all status and information about each safety inputs and outputs by simply assigning a variable, resulting in faster design and commissioning.
Sysmac integrated safety is suitable for satisfying demanding applications meeting Performance level (PLe) according to the ISO-13849-1 and SIL3 according to IEC61508. Sysmac integrated safety conforms to programming standard IEC-61131-3, and includes certified PLCopen Safety Function Blocks.
