on SWD coordinator
VALUE
Reaction SWD line
Baud rate SmartWire-DT
4=125 kBit/s
5=250 kBit/s
125 kBit/s =setpoint value
Baud rate on SWD line
Setting options:
• 4 = 125 kBit/s (setpoint value)
• 5 = 250 Kbit/s (operating system V1.10 and higher)
All slaves optional
(0 = No;
1 = Yes)
Defined for each
slave
0=Default setting
The device parameter on each SWD module is used to define
whether the module is optional
Yes
All SWD modules are optional.
The SWD line can be run with any number of failed SWD modules.
Data will be transferred to the field bus master.
The
Section “ Presence of device on SWD”, page 69 setting in
the SWD modules will have no effect.
Compatible devices allowed
(0 = No;
1 = Yes)
No
0=Default setting
The planned SWD modules in the SWD configuration must comply
with the SWD modules of the stored gateway target configuration.
If they do not, no data will be transferred to the field bus master.
Yes
Data will be exchanged if the SmartWire-DT modules connected to
the SWD line are identical to or compatible with the SmartWire-DT
modules in the planned SmartWire-DT configuration.
If they do not, no data will be transferred to the field bus master
This is displayed via the status LED on the device.
You will find the list of devices that are compatible with one
another in
Delay between cyclic data
exchange
(0 - 255ms)
At present the value cannot be changed.
Online replacement
(0 = No;
1 = Yes)
not allowed
0=Default setting;
New SWD modules on the SWD line must always be assigned an
address by importing the target configuration.
allowed
This setting enables block-by-block hot swapping for SWD
modules without having to explicitly reconfigure them via the
device by pressing the configuration button.
In addition, the "All slaves optional" to „Yes“ Otherwise, the entire
line will be disabled if communications with one or more Smart-
Wire-DT modules are lost.
