Relationship between protection zone and RFID tag

The protection zone limit is defined by a clear spatial demarcation.

If the HMI device is logged onto a machine in the protected area with a RFID tag, it is

possible to operate the machine in fail-safe mode with an enabling button within the

protected area.

Requirements for the protection zone

The protection zone must meet the following requirements:

● The protection zone must be completely demarcated and protected.

● Protection zones may not overlap.

● The protection zone must be fully visible to the operating personnel.

● A hazardous location must be visible from every point of the protection zone.

You can find a configuration example in the Appendix.

● The protection zone must be protected by a security system that prevents unauthorized

or erroneous use of the HMI device. The security system must have a safety category

that is sufficient to meet the plant requirements.

The following security systems are suitable:

● Mesh fence with access

If you use a mesh fence for the protection zone, you can protect access through an

additional security system, for example, a light barrier or a contact pressure mat. This

allows open access for an escape route during operation of the plant.

● Light barrier

● Contact pressure mat

The security system can be controlled by a safety program, such as a program for robot

control conforming to a robotics directive.
