Optical Interface
As an accessory Rockwell Automation offers an
Optical Interface including a software package for
extended diagnostic purposes.
Figure 17: Optical Interface
The adapter may be snapped on the controller during
normal operation and may be connected via the
interface to a MS-Windows personal computer for
diagnoses purposes. A detailed description about
extended diagnostic features is shipped with the
diagnostic package.
The Optical Interface offers apart from the diagnosis
of operating conditions, the possibility to select and
analyse the length of the interrupted protective field.

6. Interfacing to safety devices
The interfacing of the light curtain with the machine
control has to be control reliability, i.e. a correct
interface with a safety PLC or safety relays with
positive guided relay contacts.
Figure 18 - Diagram for automatic reset mode shows a diagram of a typical emergency stop relay
component.
Other applications are mentioned in the application
note “Safety Interfaces with GuardShield Safe 2”, on
the ROCKWELL AUTOMATION homepage.
Danger
The safety devices and the interconnection to
the machinery have to comply with the basic
safety requirements as mentioned in the current
regulations and standards.
Direct interfacing of a safety light curtain to machine
control that does not meet the necessary safety
integrity level, i.e. use of general purpose PLCs or
general purpose relays can cause serious injury or
death of persons.
Consult a professional safety engineer!
