Safety I/O
This section describes the dedicated safety inputs (Yellow terminal with red text) and the
configurable I/O (Yellow terminals with black text) when configured as safety I/O. The common
specifications in sectionCommon specifications for all digital I/Oon page31 must be observed.
Safety devices and equipment must be installed according to the safety instructions and the risk
assessment (see chapter1.5. Safety on page5).
All safety I/O are pairwise (redundant) and must be kept as two separate branches. A single fault
shall not cause loss of the safety function.
The two permanent safety inputs are the Robot Emergency Stop and the Safeguard
Stop . The Robot Emergency Stop input is for emergency stop equipment only. The Safeguard
Stop input is for all kinds of safety-related protective equipment. The functional difference is
shown below.

It is possible to use the configurable I/O to set up additional safety I/O functionality, e.g.
emergency stop output. Configuring a set of configurable I/O for safety functions are done
through the GUI, see partPart II PolyScope Manualon page85.
Some examples of how to use safety I/O are shown in the following subsections.
