OPERATION
4.1
Initial Start Up.
The
DT-NN
display is controlled by Profinet comunication.
Every time the display is connected to the power supply, three blocks of illuminated
LEDs are displayed moving throught the display. This allows to visualize the status of the LEDs.
Then, the display reads the message memory and initialises the message table.
During this time (It can take several seconds if there are many messages) the word
“INICI” is shown.
When the initialisation process is finished, the display will be ready to receive messages
from the network. While the display does not receive the first message, it shows the messages
of the internal memory, depending on the selected protocol:
Protocol TDL: Display all memory messages. Presentation mode.
Protocol PROFINET: Display message 0.
