8.1 Configurations
The following different SWD configurations are possible:
1 Planned SWD configuration
Before the SWD coordinator can start running, the device must know
which SWD modules are present and how their parameters have been
configured. This collected information is found in the planned SWD con-
figuration.
Depending on the field bus protocol that you will be using, you will be
creating the planned SWD configuration in the PLC programming envi-
ronment or in SWD assist.
2 Target configuration
Pressing the "Config" configuration button on the device will make the
system determine the actual configuration and store it as a target config-
uration in the SWD coordinator.
3 Actual configuration
By this is meant the actual physical configuration present on the SWD
line. Every Every time SWD coordinator is started, the actual configura-
tion is determined and compared with the stored target configura-
tion.time SWD coordinator is started, the actual configuration is deter-
mined and compared with the stored target configuration.
8.2 Changing the planned SWD configuration in SWD assist
To change the configuration of the SWD line, e.g., to add a new module or
replace an existing one, you will have to change the planned SmartWire-DT
configuration and import the target configuration again. Proceed as described
in
￫ Section “3.1.1 Reading of target con fi guration”, page 30.
Example: Changing or replacing a module on the SWD line
Module M22-SWD-K11LED-W has one changeover contact and one white
LED. This module is to be replaced with an M22-SWD-K22LED-W module,
which features two changeover contacts and one white LED. In order to
change the module, you would proceed as follows:
▶ Switch the power supply off at the device.
▶ Pull the M22-SWD-K11LED-W out of the external device plug.
▶ Plug the M22-SWD-K22LED-W into the external device plug.
▶ Switch on the power supply.
The SWD LED will show a red light, indicating that, as expected, the mod-
ules on the SWD line do not match the target configuration stored on the
device.
￫
Please note that the planned SWD configuration and the project
configuration are not the same thing.
While the planned SWD configuration describes the parameters
and the layout of the modules on the SWD line, the project con-
figuration is the description for the controller as such.
