are needed, is reduced because preliminary testing can be done remotely before the site visit. Consequently, overall maintenance costs and any disruptions caused by inspec tions can be minimised. The solution Omniflex provided for Sunrise Energy in cludes regular automatic testing, long-term cloud-based data logging and alarm condition alerts via SMS and email. It was installed in field marshalling panels, with the HMI panel located in the control room allowing full system visi bility, monitoring and testing. □

Functional safety over EtherCAT HMS Networks has introduced a new version of the Ixxat ® SafeT 100 module providing for users to implement safe I/Os for FSoE – Functional Safety over EtherCAT. Previously available for PROFIsafe and CIP Safety, the new version supports Functional Safety over EtherCAT according to ETG 5100 V1.2.0. The Safe T100 is designed to work together with Anybus ® CompactCom, also from HMS Networks. Anybus CompactCom handles the standard non-safe communication with the EtherCAT network and the Safe T100 handles the safe communication, in this case using FSoE. With the full implementation of the safe protocol and application layer in Ixxat Safe T100, device manufac turers and machine builders can add functional safety capabilities to their equipment. The solution is typically used in the safe emergency stop function for automation equipment such as drives, robots or process controllers. The Ixxat Safe T100 is pre-certified by TÜV Rheinland, and its conformance to the FSoE standard ETG 5100 V1.2.0 has been confirmed in the ETG test lab. This en ables users to benefit from significantly reduced devel opment time, cost, and risk when designing safe devices and systems. When coupled with Anybus CompactCom, the solu tion ensures a device or machine that provides safe and non-safe functions via one communication interface. This simplifies configuration and project planning of the over all industrial automation system. The Ixxat Safe T100 module features three two channel inputs which can detect external wiring errors, and one two-channel output. The inputs and outputs all operate with 24 V signals. All service and process data interfaces required for FSoE in the EtherCAT layer are available in the Anybus CompactCom module, such as control of the network and status LED, or transmission of the safe configuration data. As an additional safety feature, the interface between data relating to asset performance and system status, any abnormal events, like power outages or system failures, can be reported directly to all relevant personnel without delay. This enables site managers and engineers to act im mediately – and, as well as preventing unnecessary down time, leads to significant reductions in maintenance costs. Thirdly, ongoing maintenance costs are lower for enter prises that use remote monitoring technologies to monitor their CP systems. This is because difficult-to-access sys tems, such as on underground LPG containers, don’t need to be inspected physically and engineers do not have to be paid to conduct routine on-site inspections. Further more, the duration of any on-site inspections, where they

the Anybus CompactCom module and the Ixxat Safe T100/FSoE is galvani cally isolated. Other internal safety features include integrat ed temperature monitoring and shutdown to a safe state as well as channel-granular error signal ling and error handling.

Ixxat ® Safe T100 allows device manufacturers and machine builders to implement configurable, safe inputs and outputs in applications up to SIL 3 and PLe Cat.4.

Scalable for FSoE, PROFIsafe and CIP Safety The internal communication between the non-safe Anybus CompactCom and the Ixxat Safe T100 module is done according to the ‘black-channel’ principle. This clean separation between the safe and non-safe communication layers allows for customers to support all the three major safety protocols – FSoE, PROFIsafe and CIP Safety – with just one hardware design, a feature that adds to the scalability and efficiency of the solution. Customisation for OEM solutions Supplied with comprehensive implementation guidelines and user documentation, the Safe T100 module can be implemented by device manufacturers and machine builders themselves. However, HMS also supports cus tomers with implementation services, as well as porting and certification services. For specific requirements regarding, for example, form factor, plugs or number of I/Os, HMS can develop customer-specific versions of the module. For applications where it is not possible to integrate the Safe T100 – due to limited space within safety encod ers, for example, or when already existing safety hard ware limits design flexibility – HMS also offers protocol stacks for Functional Safety over EtherCAT (FSoE), CIP Safety over EtherNet/IP and CIP Safety over Sercos, all pre-certified by TÜV.
