The SK3 is also available with redundancy. Equipped with the Advanced Diagnostic Module, the SK3 enables users to perform full diagnostics on the entire physical layer. The SK3 has exceptionally low power dissipation and requires little space per channel. This means a high segment count per cabinet saving space and reducing energy costs. 13

Intelligent Fieldbus How Does a Technology Achieve 14

New Levels of Availability? By Thinking Ahead. 100% availability this is the objective of each and every development of FieldConnex fieldbus technology. The new generation of diagnostics-enabled FieldConnex components guaran tees a seamless, transparent fieldbus infrastructure that is capable of detecting and remedying a wide range of additional and rare faults. These components make it possible for the first time ever to install a fieldbus infrastructure with monitoring and protection at each output in the field. This technology brings your process plant closer to the ideal of 100% availability than any other. Zero Tolerance: Seamless Fault Monitoring Detect faults. Avoid faults. Isolate faults. This is the only reliable way to keep processes running continuously. The new, diagnostic-enabled FieldConnex components monitor the entire fieldbus physical layer and are directly installed in the field. Faults are immediately reported to the control room or plant asset management, allowing you to clear them efficiently and reliably before they can impede process communication. Intelligent Installation without Configuration The diagnostic software helps to integrate all functions into the control system. The field components do not need a control address or configuration, and the modules and infrastructure also configure themselves. This makes the planning process much simpler, and the new components start protecting the system as soon as they are configured making it easy and cost-effective to monitor the entire fieldbus infrastructure. This innovative technology provides, for the first time, maximum protection at all critical points in the infrastructure enabling plant operators to achieve unprecedented levels of availability. 15

Installation Monitoring in the Field Distribution and Field How Do We Tackle the Challenges of With Intellige The interface between the control system and the field devices is the key to reliable operation and high productivity. FieldConnex device couplers, FieldBarriers, and Segment Protectors offer a range of innovative features and the best possible protection for each individual fieldbus segment. The functionalities of both device couplers are identical, but each component is tailored to the requirements of Zone 0 or 1/Div. 1 or Zone 2/Div. 2 respectively. Automatic Early Detection for Higher Availability Faults in process communication can lead to prolonged downtime, and the resulting shutdown of production usually comes at a high cost. These issues can be caused by faults in the fieldbus installation, such as insufficient insulation between conductors, loose contacts, changes to the load characteristics due to water ingress, or maintenance work during operation. FieldConnex device couplers use intelligent diagnostics to quickly detect faulty de vices and protect segment communication by switching off the affected devices. A Pioneer in Explosion Protection FieldConnex FieldBarriers were the first device couplers on the market with galvanic isolation, which allowed explosion protection to be easily implemented in the field. The intrinsically safe outputs of the FieldBarrier are designed for Zone 0/Div. 1 devices and are equipped with short-circuit protection, which allows the segment to continue running in the event of a fault. Segment Protectors and FieldBarriers can provide any type of explosion protection that may be necessary in hazardous areas primarily intrinsically safe connections for field devices in accordance with FISCO or Entity. 16

Installation Monitoring in the Field? nt Components and Intrinsic Safety. Efficient design: The FieldBarrier in its housing ready for connection without any additional accessories. Intelligence Inside: The New 12-Channel FieldBarrier The new 12-channel FieldBarrier represents an advanced level of technology that sets new standards in reliability: The development of this new technology focused on achieving the greatest level of availability for each individual segment. As a result, the FieldBarrier boasts innovative, state-of-theart features that provide maximum protection against segment failure. Intelligent load management: Sequential activation of the outputs on start-up and load shedding in the event of overload helps to prevent excessive load current. Unique: Physical layer diagnostics on the spur provides maximum protection for each individual fieldbus segment. High packing density and 50% less space needed for installation. 17

Installation Monitoring in the Field Distribution and Field Improved Safety: Surge Protection with Diagnostics FieldConnex surge protectors reliably protect the fieldbus infrastructure from lightning and voltage spikes. As an option, they can also be equipped with an automatic self-monitoring function that records the strength of the current surge and reports the end of the useful life. Regular manual checks are no longer required. The easily interchangeable plug-in modules require no additional wiring and planning, saving time and reducing costs. These modules are also suitable for retrofitting. 18

The Segment Protector: Safe and Practical The Segment Protector shown in GRP enclosure, provides intelligent fault detection. But that s not all its mechanical design is well-thought-out and designed for simplicity. Via T-connectors on the trunk, users can interconnect as many Segment Protectors with preinstalled terminators as they wish. If necessary, the terminator is simply removed for another device coupler to be connected. This ensures proper termination in the field and makes the process very easy to control without any additional electronics. Used in conjunction with specific Power Hubs, the Segment Protector limits energy at its outputs for intrinsic safety (Ex ic) protection in Zone 2/Div. 2. In Any Size: Field Installation Made Easy The most compact version of the Segment Protector. The status LEDs are visible from the outside. For installation sites where space is particularly limited, Pepperl+Fuchs has developed the smallest junction box on the market. But in spite of these reduced dimensions, the Segment Protector still benefits from a full range of func tions. The new design means that the LEDs are visible externally, so all functions and faults can be easily and immediately recognized. Device connections from four to ten outputs can be freely selected so you get better performance in less space. An Effective Early Warning System: The Leakage Sensor For process plants, high humidity levels can be a major risk. Humidity can attenuate communication signals or cause a temporary short circuit. In the long term, moisture can cause corrosion on terminals or electronic components. The new FieldConnex leakage sensor offers reliable protection against moisture by registering moisture ingress and immediately reporting it to plant asset management via fieldbus, quickly detecting and eliminating threats to the process flow. This technology reduces the risk of failure due to moisture to almost zero another boost to availability. 19
