ABB DynLink dynamic-pulse, single-channel Jokab Safety Pluto safety architecture, if wired correctly, maintains a Performance Level e, Category 4 (PLe, Cat. 4), pursuant to International Organization for Standardization (ISO) Standard EN ISO 13849-1, for up to 10 devices on the same input circuit for the Pluto Safety PLC. The Pluto Safety PLC can also work with traditional dual-channel safety devices.
Additional features of the Jokab Safety Pluto dynamic-pulse, safety PLC include advanced diagnostics that allow quick identification of the error’s location with a solid red LED, while all downstream devices will flash red and green. Upstream devices will remain solid green.
With the introduction of StatusBus functionality, the Pluto safety PLC can now take the advanced diagnostics from a StatusBus-enabled device and transmit the status information to a process control system, such as human/machine interface (HMI). Information that is critical to many maintenance operations can help keep machine downtime to a minimum. A total of 120 StatusBus devices can be connected to a single Pluto safety PLC.
Pluto Manager software is used to program the Jokab Safety Pluto safety PLC in Ladder Logic with function blocks. Easily programmed, Pluto Manager software nevertheless will program up to 32 Pluto safety PLCs in a single network. Available at ABB’s website for download, Pluto Manager software is free of charge. Telephone support for Pluto Manager is also free of charge.
All safety functions, diagnostics, conditions and memory bits can be communicated to the machine control PLC through gateways. Common communication protocols include EtherNET/IP, EtherCAT, DeviceNET, Modbus TCP, PROFIBUS DP, PROFINET, CANopen and SERCOS III.
