This documentation contains safety instructions which refer specifically to the
software described here.
The fundamental safety information for the industrial robot can be found in the
“Safety” chapter of the Operating and Programming Instructions for System In-
tegrators or the Operating and Programming Instructions for End Users.
3.1 Safety instructions
3.2 Safety measures for “single point of control”
Overview If certain components in the industrial robot are operated, safety measures
must be taken to ensure complete implementation of the principle of “single
point of control” (SPOC).
The “Safety” chapter in the operating and programming instructions
of the KUKA System Software (KSS) must be observed. Death to per-
sons, severe injuries or considerable damage to property may other-
wise result.
KUKA.HMI Zenon can be used to read and write robot
controller variables. This allows indirect influence on the
motions and periphery of a robot. In order to avoid resulting personal injury
or material damage, the following safety instructions must be observed:
Input of values must be limited in the software by means of permissible
ranges of values.
In KUKA.HMI Zenon, the writing of values that could result in material
damage or personal injury is only permissible on the following conditions:
For connection with KUKA.PLC ProConOS, the variable
bSPOC_UserSafetyActive must be reset.
For connection with KUKA.OPC Server, the variables $USER_SAF
and $SPOC_MOTION_ENABLE must be set.
A corresponding check must be made in KUKA.HMI Zenon by the start-
up technician.
Values whose modification could cause material damage or personal in-
jury must be visually highlighted in the HMI, e.g. by marking them with a
colored background or frame.
Access to values whose modification could cause personal injury and
material damage must be restricted by defining authorized user groups
in KUKA.HMI Zenon.
A risk assessment must be drawn up for outputs that can cause hazards.
It must be possible to deactivate these outputs by means of an external
safeguard or enabling switch. The deactivation function must be tested
during start-up.
The operator control elements used for modifying values
must meet the following conditions:
Modification of values is highlighted visually.
Modification of a value must be confirmed by the operator.
This can be done, for example, using a Windows text box. This indicates, by
means of a cursor, that inputs have been made. Values are accepted by
moving the focus to a different element. The input is canceled by pressing the
ESC key.
