Important Notice
The products described herein are designed to be components of a customized machinery safety-
oriented control system. A complete safety-oriented system may include safety sensors, evalua-
tors, actuators and signaling components. It is the responsibility of each company to conduct its
own evalution of the effectiveness of the safety system by trained individuals. Siemens AG, its
subsidiaries and affiliates (collectively "Siemens") are not in a position to evaluate all of the cha-
racteristics of a given machine or product.
Siemens accepts no liability for any recommendation that may be implied or stated herein. The
warranty contained in the contract of sale by Siemens is the sole warranty of Siemens. Any state-
ments contained herein do not create new warranties or modify existing ones.
Applications
The AS-i F adapter is used to detect safety-relevant control states of mechanical contacts, e.g. 1
or 2-channel emergency stop pushbuttons, position switches or door contacts.
For this purpose, a code table with 8x4 bits, evaluated by the safety monitor, is transferred over
the AS-i bus.
When operated properly, the system attains Category 4 as per EN 954-1.
Setting address
To be able to set the address, you require the following:
• the addressing devices (Order No. 3RK1904-1AC00 or 3RK1904-2AB00) or the programming and
servicing unit (PSG of type METRAtest 36A, Gossen Metrawatt).
Valid addresses are 1 to 31. Use each address once only.
The module can be re-addressed up to 15 times. After this, the last valid address is preserved.
Important:
If the module must be addressed by means of the address jack in the installed condi-
tion, the AS-i voltage has to be switched off beforehand for plant safety reasons.
Unscrew the screw plug again after you have set the address, in order to comply with the specified
degree of protection.
