8.5 SWD device parameters
For EU5C-SWD-EIP-MODTCP all device parameters are adjustable via SWD
assist.
A "required module" is a module for which the "Required module" device
parameter = "1" so that it is enabled.
The "All devices are optional" and "Required module" device parameters
define whether there is a SmartWire-DT error when the actual configuration
is different from the target configuration.
The "Compatible devices permissible" and "Can be replaced with universal
module" device parameters define whether there is a SmartWire-DT error
when the target configuration is different from the planned configuration.
"Replacement during operation permissible" device parameter
The "Replacement during operation permissible" device parameter makes it
possible to hot swap SWD modules block by block. In addition, the"All
devices are optional" parameter must be set to "1". Otherwise, the entire line
will be disabled if communications with one or more SmartWire-DT modules
are lost.
When "Replacement during operation permissible" is enabled, the Smart-
Wire-DT coordinator will perform an automatic addressing routine if it
detects any differences between the target configuration and the actual con-
figuration when comparing them. The comparison between the planned
SmartWire-DT configuration and the target configuration will continue to be
performed.
Examples
Remember that if "All devices are optional" is set to "1"and is enabled, the
SWD line will continue to run even if a module on the line drops out - regard-
less of whether "Replacement during operation permissible" is enabled or
disabled.
When "Replacement during operation permissible"="0", this means that the
device parameter is not enabled. If the module is replaced with an identical
module while the power is off, the target configuration will have to be
imported again after the power is turned back on. The SWD line will not start
running. In other words, the user is required to intervene.
When "Replacement during operation permissible"="1", this means that the
device parameter is enabled. If the module is replaced with an identical mod-
ule while the power is off, a new target configuration will be automatically
imported. If this imported target configuration matches the planned Smart-
Wire-DT configuration, the SWD line will start running. The SWD line will also
NOTICE
Hot swapping modules on the SWD line is only allowed in con-
junction with the SWD4-FFR-PF1-1 power supply module and
SWD4-FFR-ST1-1 cable adapter SmartWire-DT components.
