Connecting to CIP safety with new safety module

IXXAT Safe T100 is an all-in-one safety solution allowing users to implement configurable, safe inputs and outputs in applications up to SIL 3 and PLe Cat.4. The Safe T100 module is integrated into an industrial device used together with the Anybus CompactCom multi-network communication products. CompactCom handles communication between the host device and an industrial network (such as PROFINET or EtherNet/IP), while the Safe T100 handles the safe signals.

By using the new IXXAT SafeT100/CS, users can implement safety standards faster and easier compared to in-house development. 

The new IXXAT Safe T100/CS
The module has three inputs (dual-channel) - with a detection functionality for external cabling errors - as well as one output (also dual-channel). All inputs and outputs operate with 24V signals.

The IXXAT Safe T100 can be used to, for example, implement a safe emergency stop function for drives or process controls (within applications for welding, gluing, riveting, etc.). Hereby, the end user gets a device which handles secure and non-secure communication via one single communication interface. This simplifies both the configuration and the development of the entire system. 

Pre-certified and conformance tested
The combination of IXXAT Safe T100 safety hardware and software as well as the pre-certification by TÜV Rheinland makes the development of secure devices and systems faster and easier resulting in reduced development time, costs and risks. The CIP Volume 5 compliance of the IXXAT Safe T100 has been tested and confirmed in the ODVA test laboratory.

Modular concept for CIP Safety and PROFIsafe
The CIP Safety version of the module (IXXAT Safe T100/CS) is used together with the well-known Anybus CompactCom products from HMS. CompactCom handles the communication with the non-secure EtherNet/IP network and the secure communication is handled by Safe T100 according to the 'black-channel' principle. Switching between the two supported protocols (CIP Safety and PROFIsafe) can be done on the same IXXAT Safe T100 hardware using the firmware upload option.

All modifications of the EtherNet/IP layer - necessary for CIP Safety operation - are already implemented within the Anybus CompactCom module, like e.g. control of the network and status LEDs, transmission of the secure configuration data, and more.

As an additional safety feature, the interface between the Anybus CompactCom module and the IXXAT Safe T100/CS is galvanically isolated.

Other internal safety features include integrated temperature monitoring and switch-off to a safe state, channel-based error signalling and error handling as well as optional automatic or manual reset of channel errors.

The IXXAT Safe T100 stores the configuration data within a non-volatile memory, which results in very short start-up times. The module also supports a manual and DHCP-based IP address setting.

Customised implementation or OEM solutions 
Thanks to the comprehensive implementation guidelines and user, the module can be implemented by the device manufacturers themselves. However, HMS also supports customers with implementation, porting and certification services. As an alternative, parts of the development or the entire project can be performed by the HMS Safety Development Team on behalf of the customer.

For specific requirements regarding form factor, plugs or number of IOs, customer-specific versions of the IXXAT Safe T100 can also be customised by HMS.

IXXAT Safe is more...
For applications where the integration of the IXXAT Safe T100 is not possible (e.g. due to limited space within safety decoders or a limited flexibility due to already existing safety hardware) HMS also offers pre-certified protocol stacks for Functional Safety over EtherCAT (FSoE), CIP Safety over EtherNet/IP and CIP Safety over Sercos.
