7.5.3 Application cases for the effective use of the device parameters
Compatible devices allowed enabled
The system is already running and both the target configuration and the
planned SWD configuration are stored on the SWD coordinator. The SWD
coordinator is switched off in order to replace a defective module. As you
don't have a replacement of the same type, you use a compatible type
according to the table.
When you switch the SWD coordinator back on, the actual configuration will
be determined.The automatic configuration comparison will detect the new
module and signal this discrepancy by showing a solid red light on the Config
LED. You will then have to press the "Config" configuration button. After this,
the SWD coordinator will import the new target configuration. The Smart-
Wire-DT coordinator will compare the target configuration with the planned
SmartWire-DT configuration and detect a difference between both. The sys-
tem will then check whether the "Compatible devices permissible" option has
been enabled.If it has, the SWD coordinator will check whether the module
in the target configuration is really compatible with the module in the planned
SWD configuration. If it is, there is no SmartWire-DT error and the SWD line
will start running.
Can be replaced with universal module enabled
You've designed a system and you want to first use a universal module for a
specific module, as the actual specific module will be installed as part of a
later upgrade. To do this, you enable the „Replacement by universal
modul“=„allowed“ device parameter.
This makes it possible for the module in the planned SmartWire-DT configu-
ration to be replaced by a universal module in the target configuration.Once
you install the universal module on the de-energized SWD line, you switch on
the SWD coordinator and press the "Config" configuration button to import
the target configuration. The check against the planned SWD configuration
then shows that the configurations do not match. After this, the SWD coordi-
nator checks whether the „Replacement by universal modul“= „allowed“
device parameter is enabled for this module. If it is, the SWD line will start
running.
