Detailed Description of the Module
Module restart completed (Xn2), Module restart request (Yn2)
● A restart is necessary to activate the following new settings:
– Function mode (Un\G21), refer to section 3.5.2
– Baud rate (Un\G24), refer to section 3.5.4
– Node-ID (Un\G27), refer to section 3.5.6
– NMT master setting, refer to section 4.8.5.
All not saved settings will be lost.
● To restart the module, please set the module restart request (Yn2) signal to ON. The module will
be set to initialization state as indicated by the Un\G25 bit 7 (refer to section 3.5.5). After the
module is restarted, the module restart completed (Xn2) will be set to ON. The module restart
request (Yn2) signal can be reset to OFF. Not setting this signal back to OFF will cause that the
module will be restarted again and again. The restart procedure will take approx. 6 seconds to
complete.

Module in Layer 2 online mode (Xn3), Layer 2 online mode request (Yn3)
● The Layer 2 online mode request signal (Yn3) must be set to ON to start data exchange with other
network nodes.
● The module in Layer 2 online mode signal (Xn3) will turn ON if the module can be set to online
mode. The configuration of the module can only be changed while this signal is OFF..
NOTE
In case a configuration buffer memory was changed during online mode, Un\G29 bit 5 is set to ON.
Message transmit trigger completed (Xn4), Message transmit trigger request (Yn4)
● The transmission trigger of a message in Layer 2 mode which is set in Un\G8400 to Un\G8402
must be started with a message transmit trigger request (Yn4).
● The message transmit trigger completed signal (Xn4) will turn ON when all the messages have
been written into the transmit buffer. Please refer also to section 3.6.4.
