AS-i Safety at Work 5
Safety at work - 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. Mixed operation of standard and safety-related components via the yellow AS-Interface cable 6
Features of the system Can be used up to control category 4 / PLe / SIL 3 Response time max. 40 ms Safe data transmission approved by BIA 1 and TÜV 2 Full compatibility with all other AS-Interface components according to EN 50 295 and IEC 62026-2 Use of the standard AS-Interface protocol Maximum extension of the system with 31 safety slaves Stop category 0 or 1 can be selected BIA¹: Berufsgenossenschaftliches Institut für Arbeitssicherheit TÜV²: Technischer Überwachungsverein 7

Function of the safety slaves Each slave has a specific 8 * 4 bit code table Through a teach-in function the safety monitor reads in the code tables of all safety slaves During operation permanent comparison of the expected and the transmitted code tables takes place The system is switched off by the safety monitor when the expected code the transmitted code, i.e. when: A stop is called (0000) Communication is interrupted The transmitted sequences are wrong The safety slave is disrupted Slave responses are missing or disrupted 11

Function of the safe output 1 safety relay output Diagnosis + 1 input (EDM) AS-i relay output module with standard 4 inputs Safety address AB-Slave Safety address + AB slave 17
Function of the safe output A safe output needs a safe address and a A/B-address The voltage supply is made completely out of AS-i The safety unit sends a 7 x 4 code sequence as answer to the master request the safe output hears this code sequence and compares it with the intern code sequence and switches correspondingly Several outputs can have the same safe address but never the same unsafe address The unsafe address is used for the transmission of diagnosis data is transmitted or for switching the safe output (after validation by the safety logic) 18
Function of the safe output Safety unit Safe output slave Master sends request Safety unit answers with safe code sequence The safe output slave compares the code sequence (that depends from the slave address) and switches correspondingly that means it is possible to have several safe output slaves on the same safe address 19

Device diagnosis Diagnosis in plain text at the display It is possible to obtain an improved diagnosis directly via the display even without programming it Specialties as e.g. duplicate AS-i address detector, AS-i earth fault detector and AS-i noise detector are already integrated The current status of the safety components can be displayed as well as the switch off history A complete diagnosis is available without further programming 33

Device chip card Chip card for storage integrated in the device Storage of up to 4 different programs Very simple change in the functionality possible by only changing the chip card (PC is not required) If you replace the device you will only have to insert the chip card into the new device Operation is also possible without chip card In case of failure the downtime is reduced drastically 35
