June 17, 2015 - Yaskawa announces EtherNet/IP safety software for DX200 robot controller offers the significant benefits of workcell installation simplicity and ease of integration by reducing the amount of robot control wiring required. The EtherNet/IP safety interface can be used with or without Yaskawa Motoman’s Functional Safety Unit (FSU) capability, allowing a wide range of safety control options.
The EtherNet/IP safety software requires no additional hardware in the robot controller, and operates by allowing the exchange of safety input/output data between the DX200 robot controller and a safety PLC – typically a Rockwell Automation GuardLogix PLC. When multiple robot controllers are managed by one master PLC, the GuardLogix PLC can manage the safety system (E-stops, safety gates, etc.). On multiple controller integrations, this replaces the unique dual channel wiring between the PLC and every controller, reducing redundant wiring and I/O modules, and allowing for easier troubleshooting.
All machine safety signals, Functional Safety Unit (when included) signals and logic can be mapped to EtherNet/IP safety inputs and outputs. The safety communication interface is rated at Category 4 safety by TÜV Rheinland. It is also ODVA compliant. When EtherNet/IP safety is enabled, the standard (non-safe) EtherNet/IP communication interface is also provided with both scanner and adapter capabilities available for a non-safe EtherNet/IP network.
