The EtherCAT
®
master loads this configuration data into the gateway via
SDOs when the gateway is in state
Pre-Operational
.
Also, the device parameters (
Parameters
) of sub index
22
are loaded into
the corresponding SmartWire-DT device, if the device is an I/O module (the
purpose of the device parameters is to configure the sensors of I/O
modules).
The module ID (
Product code
) of sub index
06
and the configuration data
(
CFG
) of sub index
20
are needed by the gateway for identification and
configuration purposes and must not be changed. The device options
(

) of
sub index
21
and the device parameters (

) of
sub index
22
on the other hand can be edited if necessary. This is
described in the following sections.

Configuring device options of SmartWire-DT devices in
TwinCAT
9.3.2.1
Overview
Each SWD device carries an element for configuring certain device options
in TwinCAT. With this
Options
element (sub index
21
), you can determine
for each device individually, whether its presence in the SmartWire-DT
network is mandatory or whether it may be substituted by an M22-SWD-
NOP universal module.
The preset defaults for all devices are:
Presence in SmartWire-DT network: device must be present
Replacement/substitution by universal module: not allowed
Note:
If you reconfigure the “presence option” of an individual device in
order to allow it to be missing in the SmartWire-DT network, this option
will only be effective if the
All Modules Optional
(index
0x2100:08)
parameter of the Coordinator is being kept at its default
0x00
setting.
This allows you to configure the “presence option” for each device
individually in its device options element.
See also
Configuring SmartWire-DT Coordinator
section on page 53.
The parameters of the
Options
element (i. e. the device options) are
configured by entering a single hexadecimal options byte.
Please note that this byte does not only define the two options mentioned
above (i. e. presence in the SWD network and replacement by universal
module), but also defines other parameters like e. g. payload formats. The
presets of these other parameters may vary from device to device and must
not be changed by the user.
Each parameter is represented by a single bit in the options byte, each bit
set TRUE has an individual byte value. The assignment of parameters to
bits and their byte values are shown in the subsequent table:
