Using a unified cybersecure platform to support comprehensive industry 4.0 connectivity
■ FSoE safe torque off that meets PLd according to EN ISO 13849-1 and SIL2 according to IEC 61508
EtherCAT control network support and EtherNet/IP connectivity for linking to factory automation controllers. They have slots for two option boards providing expanded connectivity, including serial communications and analog I/Os. These controllers fully conform with IEC 61131-3 programming standards to simplify and speed commissioning. Omron’s NX1P is an essential all-in-one controller that can manage advanced motion, vision, safety I/O, networking, and IoT connectivity. For more complex machine control applications that can benefit from up to 254 CIP safety connections, up to 62 axes of motion, 256 EtherCAT nodes, 1 Gbps EtherNet/IP ports, and OPC UA, network designers can turn to the Sysmac NX502 controllers. Advanced machine control The NX502 controllers are suited for use at the EtherCAT and EtherNet/ IP network levels, and they include MQTT, OPC UA, and structured query language (SQL) capability for connecting to the company’s IT and OT systems and the cloud. NX502 controllers have slots for up to four EtherNet/IP (EIP) expansion cards with data Transfer rates up to 1 Gigabit per second (Gbps). Each EIP card creates a
Machine controllers Machine controllers like the NX1P2 series from Omron can fulfill two functions. They can be used to directly control various servos and other machines on the EtherCAT level of real-time machine control, and they can provide a link up to the EtherNet/ IP factory automation level. These controllers support integrated sequence and motion control and connect to up to eight controlled axes using EtherCAT (Figure 2). They also feature
Both the hardwired and FSoE safe torque off meet EN61800- 5-2(STO). A hardwired solution can bring the line to a standstill by cutting main power. FSoE supports more nuanced responses and can send a Safe Operating Stop command, only slowing the motors in the affected area. FSoE can also send a Safe Stop command, stopping the motors when needed.
