Connecting the safe stop of an existing robot controller to an upper-layer factory safety network can be as simple as integrating a Ixxat Safe T100 into the internal robot network. The Ixxat Safe T100 transfers the safe stop signal from the factory safety network to the safe stop digital input of the robot.
The HMS safety stacks can be used to implement more complex safety functions inside the robot network up to safety master control PLCs.

The Ixxat Safe protocol stacks enable the central safety PLC to communicate safely with the distributed safety slaves. Using the pre-certified Ixxat Safe stacks, the PLC manufacturer can concentrate on his safe control tasks and rely on the proper HMS safety protocol integration.  

The simplest way to make a system safe is to prevent a dangerous situation. The safe I/Os of the Ixxat Safe T100 are ideally suited for implementing a safe access control. With its safe inputs the state of a door lock, rolling door, light curtain or laser scanner can be acquired and forwarded to the central safety PLC. On the other hand automatic doors can also be safely stopped by using the safe outputs of the Ixxat Safe T100.

AGVs (Automated Guided Vehicle) need on the one hand an autonomous safety function to quickly react on dangerous events locally, on the other hand the AGV is part of a global safety network which controls the entire AGV fleet. The Ixxat Safe T100 can be used here to connect the local AGV safe stop to the upper layer safety network. Thus the AGV can be designed, setup and approved independently from the final factory network. In addition, simple safety sensors like proximity switches or laser scanners can be connected to a local AGV network by using the Ixxat Safe T100.

Machine tools often use complex PLCs to control the tools and the material processing. The Ixxat Safe software stacks can for example be used to implement the safe communication network within these machines. The Ixxat Safe T100 can acquire or control simple external safety signals to connect the machine tool module to various cell or plant safety controller networks.

Module or Stack – What fits best?

Module based

The module-based approach is particularly suitable for applications which only need simple safe I/O functionality. The module transfers physical safety I/Os into safety fieldbus signals and vice versa. The Ixxat Safe T100 module completely takes care of the safety-related protocol and I/O handling. The integrator does not need to touch any safe software or hardware part on the Ixxat Safe T100 for the final device certification. Moreover, the Ixxat Safe T100 module enables the connection to various safety fieldbus protocols with the same hardware concept.

Protocol stack based

Safety protocol stacks are used whenever the safe application is more complex than just exchanging a limited number of safe I/O bits. Complex safety sensor or drive applications as well as safety PLC programs must operate closely together with the safe communication entity to be able to exchange larger amount of safety data or safety-related configuration data.
