Diagnostics via AS-i
With no address of the Safety-Monitor
„0000“ means Safety device OFF
„Code“ means Safety device ON
Disadvantages:- no Monitor failures are detected
- not all Device failures are detected
- no defined reason given for activation
The status of the monitor and all relevant devices can be transfered into
the PLC. A function block for the S7 is available.
Advantages: - detailed diagnostics including monitor failure, timing error
waiting for start, test neccessary, and slave address

What happens if ...
• ... the safety monitor is defective:
• The configuration data of the system is stored in the monitor and
if necessary can be directly transmitted to the new monitor. In
addition a safety check must be carried out, i.e. all safe
components must be actuated and their functioning checked by a
competent person.

Excellence in

Folienthema/Folie 12/Jahreszahl
• ... a slave is defective:
• You can take an identical substitute slave. The safety monitor
accepts this as a substitute and internally adjusts to the new code
table. The safety protocol must be updated.
Can you ...
•... add a safe slave to an existing network?
•Yes! The monitor accepts additional safe slaves. The safety protocol
must then be updated.
•... run AS-Interface Safe under Version 2.1?
•All components of Safety at Work can be run under the extended AS-Interface
specification Version 2.1. Safe slaves are, however, always single slaves, as they
need a complete AS-Interface address. A mixed configuration is possible but you
must take into acccount that A and B addresses eliminate the full address from
your configuration table.

•... remove safe slaves from an existing network?
•No! To prevent manipulation this is not possible. If a safe slave is removed, the
safety monitor switches off and will not switch on again until a new configuration
is down loaded into the monitor via a PC.
AS-Interface Safe can be configured
quickly and easily via Drag & Drop
