Configuration
There are three types of configurations that are relevant for commissioning
and operating the EU5C-SWD-POWERLINK gateway.
The
actual configuration
is the current actual constellation of the devices
at the SmartWire-DT bus connected to the SmartWire-DT interface of the
gateway. It is always scanned after each restart of the gateway. This
procedure can not be influenced.
In case the actual configuration complies with the configuration envisaged
for operation, the actual configuration can be captured as
target
configuration
and stored zero-voltage safe in the device. This capturing
and storing of the actual configuration as target configuration can be
achieved either by pressing the configuration button located at the front
panel of the gateway or by using the SWD-Assist software (for the position
of the configuration button, see
Device Picture
section on page 27).
This target configuration is then available within the gateway even after
power-off or restart of the device. If a target configuration has been stored,
the gateway checks on each restart whether the actual configuration
complies with the target configuration. In case the gateway detects
inadmissible deviations, it will not go into operation. If the actual
configuration deviates from the target configuration because of a device
failure or removal on the SWD bus, the
SWD LED
on the gateway starts to
blink red (for the position of the SWD LED, see
Positions of the LEDs
section on page 28).
If no errors are detected, the gateway is in principle ready for operation, but
remains in waiting until the so-called planned configuration is downloaded
to the gateway via the SWD-Assist software.
Without a target configuration, the gateway will not go into operation. The
target configuration therefore has to be generated
when you commission the gateway for the first time,
after replacing a SmartWire-DT slave or
after deliberately changing the setup of the SmartWire-DT network in
any other way.
The third configuration is the
planned configuration
(in this document also
called
project configuration
). It is created by using the
SWD-Assist
software and contains the desired configuration and the parameters of the
SmartWire-DT network. It can be manually created in SWD-Assist by
adding the individual device symbols in the “workbench” window, or it can
be automatically created by taking over (i. e. reading-in) the target
configuration from the gateway. The latter method is less prone to errors
and therefore recommended.
The project configuration has to be complemented in SWD-Assist with the
device-specific parameters of the SWD slaves and the POWERLINK-
specific parameters (i. e. the node ID of the gateway). It then has to be
downloaded from the configuration PC to the gateway via USB, where it is
stored (like the target configuration) zero voltage-safe in the flash memory
of the device.
