4. Electrical connection
4.1 General information for electrical connection
The electrical connection may only be carried out by
authorised personnel in a de-energised condition
The connection to the AS-Interface system is realised through an M12
connector or an AS-i flat cable clamp The wiring configuration of the
M12 connector is defined as follows (to EN 50295):
Pin assignment M12 connector
4-pole

PIN 1: AS-i +
PIN 2: spare
PIN 3:AS-i -
PIN 4: spare
5. Functions and configuration
5.1 Programming the slave address
The slave address is programmed through the AS-i connector Any
address from 1 to 31 can be set by means of the AS-i bus master or a
hand-held programming device
5.2 Configuration of the safety monitor
The safety switch can be configured in the ASIMON
configuration software with the following monitoring devices
(refer to ASIMON manual):
Double channel dependent
• Optionally with startup test
• Synchronisation time typically 0.1 - 0.5 s
The configuration of the safety monitor must be tested and
confirmed by a qualified and authorised safety expert/safety
engineer
5.3 Status signal "safety release"
The "safety release" status signal from a Safety at Work slave can be
cyclically queried by the control system through the AS-i master To
thiseffect, the 4 input bits with the varying SaW code of a Safety at
Work slave are evaluated through an OR operation with 4 inputs in the
control system
6. Diagnostic
6.1 Internal LED indications
The LED's have the following meaning (to EN 50295):
LED yellow
Channel 1 / AS-i SaW-Bit 0,1
LED green/red
(AS-i duo LED):
AS-Interface supply voltage/
AS-Interface communication error or
slave address = 0 or periphery error
LED yellow
Channel 2 / AS-i SaW-Bit 2,3
6.2 Read-out of the parameter ports
The parameter port P0 to P3 of an AS-i slave can be read out through
the control interface of the AS-i master (see component description) by
using the "Write parameter" instruction (with hexadecimal value F) This
(non-safe) diagnostic information from the reflected parameters or the
answer to a "Write parameter instruction" can be used by the user for
diagnostic purposes or for the control programme
