Function
Addressing
All modules of the Slimline S22.5, S45 and F90 series as well as
the flat module can be addressed via an integrated addressing
socket also in the mounted state. An addressing unit is therefore
necessary (AS-Interface addressing and diagnostics unit 3RK1
904-2AB01).
LED diagnostics indication
SlimLine Series
AS-Interface modules of the SlimLine Series have, in addition to
status indicators for inputs and outputs, two LEDs for indicating
the status of the module.
1) No LED for 3RK1 400-0BE00-0AA2, 3RK1 402-0BE00-0AA2 and 3RK1 100-0CE00-0AA2.
F90 module (16I)
All modules of this series have, in addition to status indicators for
inputs and outputs, one LED to indicate the status of the AS-In-
terface voltage.
Flat module and F90 module (4I/4O)
The flat module and F90 module with four inputs and four out-
puts have a dual LED for diagnostics functions.
