Network Communication
As soon as a setting is stored, the Emergency "Changed HW configuration" is
not sent any longer if the bus coupler is started up again without changing the
module configuration.
Attention
If following the storage of a configuration only the module ID is changed via
the DIP switch, the saved configuration is continued to be used. In other
words, all module ID specific entries in the object directory (objects that are
module ID dependent and have the „rw" attribute) signal with the old values.
(i.e. Emergency ID,...)
4.3.4.2.12 Object 0x1011, Restore default Parameters
Idx
0x1011
This object allows to reset the user stored parameters to the original default
values.
Sub-indexes 2 and 3 are not supported.
The load command is processed in the background and takes approx. 2-3 sec-
onds. When the performance is finished, the SDO reply message is sent. Com-
munication can be continued during performance using SDOs. An error mes-
sage is only tripped with another attempt to send a load command, if the pre-
vious one is not yet completed. It is also not possible to trigger a load com-
mand for as long as „Save" is active.
4.3.4.2.12.1 Sub-index 1 - Permanent entry of default parameters
Writing the signature „load" (lower case letters ASCII - MSB 0x64 0x61 0x6F
0x6C LSB) into the index 0x1011 sub-index 1 entails loading of the standard
factory settings after the following Power ON and each further Power On (un-
til the next SAVE command is given).
4.3.4.2.12.2 Sub-index 4 – On-off entry of default parameters
Writing the signature „load" (lower case letters ASCII - MSB 0x64 0x61 0x6F
0x6C LSB) into the index 0x1011 sub-index 4 entails loading of the standard
factory settings once only after the following Power ON. The saved configura-
tion is re-loaded after each further Power ON. This feature can, for instance,
be used during the development phase in order to quickly obtain a behavior
comparison of saved and default configurations without having to re-set and
re-store all parameters each time.
