Masterclass 2001: Safety Integrated Excellencein Automation&Drives: Siemens Folienthema/Folie 2/Jahreszahl Name & Department AS-Interface Safe - Headlines Integration of all binary safety-related components in AS-Interface, such as: Emergency stop Protective door switch Safety light barriers/grids Contactor controls, etc. Combined operation of standard and safety-related components via the yellow AS-i cable Fail-safe PLC or special master not necessary due to safety monitor It is possible to form groups of safe signals within a network Diagnostics via standard master/standard PLC

Masterclass 2001: Safety Integrated Excellencein Automation&Drives: Siemens Folienthema/Folie 9/Jahreszahl Name & Department 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 With an ASI address of the Safety-Monitor 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

12
Masterclass 2001: Safety Integrated Excellencein Automation&Drives: Siemens Folienthema/Folie 12/Jahreszahl Name & Department What happens if...... 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....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.
13
Masterclass 2001: Safety Integrated Excellencein Automation&Drives: Siemens Folienthema/Folie 13/Jahreszahl Name & Department Can you...... add a safe slave to an existing network? Yes! The monitor accepts additional safe slaves. The safety protocol must then be updated.... 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.... 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.
14
Masterclass 2001: Safety Integrated Excellencein Automation&Drives: Siemens Folienthema/Folie 14/Jahreszahl Name & Department AS-Interface Safe can be configured quickly and easily via Drag & Drop Assignment of the slaves to the output switching elements Operating modes can be set: Mode 1: Stop - Category 0 + 0 Mode 2: Stop - Category 0 + 1 Mode 3: Stop - Category 0 + two-hand operation Mode 4: Stop - Category 0 + door latching Downloading of the processed data with password protection Protection against manipulation of the configuration data Protocol of the configuration In the case of error, monitoring of the system status
