ET 200L, ET 200L-SC and ET 200L-SC IM-SC Distributed I/O Device
EWA 4NEB 780 6009-02c
The ET 200L distributed I/O device and Smart Connect starts up automati-
cally when the power supply is turned on. A separate switch is not available.
During start-up, both LEDs (ON and BF =Bus Fault) are on.
The ET 200L distributed I/O device ...
Sets the outputs to ”0”.
Applies the PROFIBUS address from the two rotary switches.
Receives the configuration data from the DP master and evaluates the
details contained in the configuration data. If the configuration agrees
with the installation, the ET 200L distributed I/O device and Smart Con-
nect initiates data exchange, and the BF LED goes off.
The ET 200L-SC or ET 200L-SC IM-SC behaves as follows when analog SC
modules are connected:
SC modules can only be detected at ET 200L-SC or ET 200L-SC IM-SC
start-up after power on. If the 24V supply on the SC terminal block is not
yet connected at start-up, SC modules are not detected.
The ET 200L-SC or ET 200L-SC IM-SC starts up when the power supply
is switched on.
This behavior can result in the following errors:
A configured SC module is not detected at start-up. As a result, a diagnos-
tic interrupt occurs with a parameterization error for the SC add-on, and
the SF LED on the ET 200L-SC or ET 200L-SC IM-SC comes on.
ET 200L-SC (as of version 3), ET 200L-SC IM-SC. An SC module or
counter module fails during operation. As a result, a diagnostic interrupt
occurs with a module error for the SC add-on, and the SF LED on the
ET 200L-SC or ET 200L-SC IM-SC comes on.
After start-up, data exchange is initiated between the DP master and the
ET 200L distributed I/O device and Smart Connect.
The data exchange is displayed by the ET 200L distributed I/O device as fol-
lows:
The green operating LED (ON) is on.
The bus fault LED (BF) is off.
The inputs and outputs are enabled.
Conductive inputs and outputs are indicated on the status LEDs by the
corresponding LED flashing.
