CM AS Interface, communication states

The CM AS Interface has three communication states: The LED is lit green, red or flashes red/yellow.

LED AS-I is lit

CM AS Interface, behavior on communication failure

If the AS Interface voltage fails, communication between the LOGO! system and the expansion modules, which are arranged to the right of the LOGO! CM AS Interface expansion module, is interrupted.

Recommendation: Position LOGO! CM AS Interface on the far right side.

If communication is interrupted, the switching outputs are reset after about 40 to 100 ms.

CM EIB/KNX, communication states

The CM EIB/KNX has three communication states: The LED is lit green, red or orange.

CM EIB/KNX, behavior on communication failure

LOGO! voltage failure

If there is a power failure of LOGO! or a disruption in the communication to the LOGO! master or to the communication partner on the left side, the outputs are set to 0. The RUN/STOP LED lights up red after a second.

LOGO! voltage recovery

LOGO! starts up again, CM EIB/KNX sends the parameterized states.

CM EIB/KNX voltage failure

All the inputs of the LOGO! master on the EIB are set to 0 by the LOGO! master.

CM EIB/KNX voltage recovery

All the outputs of the LOGO! master on the EIB are updated. The inputs are read by the EIB depending on the parameterization.

Short circuit on the bus or bus interruption

The behavior can be parameterized in the LOGO! configuration window of the application program in ETS (EIB Tool Software). The red light is set after 5 seconds.

Bus recovery

The behavior can be parameterized in the LOGO! configuration window.
